The present invention relates to a data security system and method and, more specifically, to a process, program and system which operates to secure files and data objects in a computer system and network with multiple independent levels of security (MILS). The invention extracts on a granular basis, disperses, via a controlled release of data segments, to storage locations, and permits reconstruction utilizing security protocols to provide a security system for data. BACKGROUND OF THE INVENTION The extensive use of computers and the continued expansion of telecommunications networks, particularly the Internet, enable businesses, governments and individuals to create documents (whether text, images, data streams or a combination thereof, sometimes identified as “data objects”) and distribute those documents widely to others. Although the production, distribution and publication of documents is generally beneficial to society, there is a need to limit the distribution and publication of security sensitive words, characters or icons. Concerns regarding the privacy of certain data (for example, an individual's social security number, credit history, medical history, business trade secrets and financial data) is an important issue in society. In another words, individuals and businesses have a greater concern regarding maintaining the secrecy of certain information in view of the increasing ease of distribution of documents through computer networks and the Internet. U.S. Pat. No. 6,055,544 to DeRose et al. discloses the generation of chunks of a long document for an electronic book system. DeRose '544 discloses solutions available to book publishers to publish books in electronic format on the worldwide web. One of the problems is that the books are published as small document fragments rather than publishing an entire book which, due to the formatting, protocol and command structure on the Internet, downloads an entire book to the user. The problem involved with publishing small documents is that there is no relationship to other portions of the book. See col. 3, lines 51-55 and col. 4, lines 3-5. One methodology to solve the problem involves inserting hypertext links in the book. This places a large burden on the book publisher. Col. 4, lines 19-21. Accordingly, it is an object of DeRose '544 to provide a mechanism for accessing only a portion of a large, electronically published document and automatically determining what portion of the document to download to the user based upon user selections that is, previous portions and subsequent portions of the document are downloaded with the selected portion, without maintaining separate data files for each portion of the document. Col. 4, lines 34-39. In other words, if a person wanted to access chapter 4 of a text, the system in DeRose '544 would display chapter 4, chapter 3 (the preceding chapter) and chapter 5 (the subsequent chapter). This publishing of portions of the document utilizes a subset of marked up elements established as being significant and a second subset of elements being less significant. For example, “Title elements” define a table of contents. A first representation of the document structure defined by all of the marked up elements maybe used in combination with a second representation of the document structure defined only by the significant elements to control selection of portions of the documents such that previous and subsequent portions may be selected and rendered in a consistent and intuitive manner.” Col. 4, lines 38-55. A computer system stores a first representation of the hierarchy of all elements in the electronic document. As example, this may be each chapter in its entirety. The computer also stores a second representation of the hierarchy of only significant elements in the electronic document. As an example, this may be a listing of each chapter without the text associated with the chapter. In response to request for a portion of the document, the computer system selects the portion defined by the significant element in the second representation. For example, if the user requested chapter 4, the entirety of chapter 4 would be downloaded from the web server to the client computer. In addition to rendering or publishing the selected chapter, the computer system looks to the relationship of the elements in the first representation of the hierarchy (the list of all chapters) and downloads from the web server the adjacent chapters. In this example, this would involve downloading chapters 3 and chapter 5. In a further embodiment, the computer system selects only a leaf element of the second representation as a significant element during the download. See the Summary of the Invention, col. 4, line 40 through col. 6, line 14. U.S. Pat. No. 5,832,212 to Cragun et al. discloses a censoring browser method for viewing downloaded and downloading Internet documents. The abstract describes the system as including a user profile including user selected censoring parameters. Data packet contents are received from the Internet and the packets are compared with the user selected censoring parameters. Responsive to the comparison, the received data packet contents are processed and selectively displayed. The user selected censoring parameters include censored words and word fragments, and user selected categories. Compared word and word fragments can be removed and selectively replaced with predefined characters or acceptable substitute words. Tallies of weights for user selected categories are accumulated and compared with used selected threshold values. A predefined message can be displayed responsive to an accumulated tally exceeding a user selected threshold value without displaying the received data packet contents. U.S. Patent No. 6,094,483 to Fridrich discloses an encryption methodology hiding data and messages in images. In one application of the system in Fridrich '483, a method is disclosed of embedding a secret digital square image with 256 gray levels within an image carrier. The secret image is first encrypted using a chaotic Baker map. The resulting image is a random collection of pixels with randomly distributed gray levels without any spatial correlations. The carrier image is twice the size (height and width or 2n�2m) the secret image with 256 gray levels. The carrier image is modified according to a mathematical formula. U.S. Pat. No. 5,485,474 to Rabin discloses a scheme for in formation dispersal and reconstruction. Information to be transmitted or stored is represented as N elements of a field or a computational structure. These N characters of information are grouped into a set of n pieces, each containing m characters. col. 1, lines 37-46. The system is used for fault tolerance storage in a partitioned or distributed memory system. Information is disbursed into n pieces so that any m pieces suffice for reconstruction. The pieces are stored in different parts of the memory storage medium. A fairly complex mathematical algorithm is utilized to provide reconstruction of the information utilizing no fewer than m pieces. U.S. Pat. No.6,192,472 B1 to Garay et al. discloses a method and apparatus for the secure distributed storage and retrieval of information. Garay '472 identifies the problem as how to store information in view of random hardware or telecommunications failures. Col. 1, lines 17-20. The initial solution is to replicate the stored data in multiple locations. Col. 1, lines 28-31. Another solution is to disburse the information utilizing in Information Disbursal Algorithm (IDA). The basic approach taking in IDA is to distribute the information F being stored among n active processors in such a way that the retrieval of F is possible even in the presence of up to t failed (inactive) processors. Col. 1, lines 40-44. Another issue is the utilization of cryptographic tools. With the use of tools called distributed fingerprints (hashes), the stored data is distributed using the fingerprints and coding functions to determine errors. In this way, the correct processors are able to reconstruct the fingerprint using the code's decoding function, check whether the pieces of the file F were correctly returned, and finally reconstruct F from the correct pieces using the IDA algorithm. Col.2, lines 50-59. Garay '472 also discloses the use of Secure Storage and Retrieval of information (SSRI) with the added requirement of confidentiality of information. Col. 3, line 56. With this added requirement, any collision of up to t processors (except ones including the rightful owner of the information) should not be able to learn anything about the information. Confidentiality of information is easily achieved by encryption. Col. 3, lines 56-61. The issue involves encryption key management, that is, the safe deposit of cryptographic keys. Garay '472 discloses confidentiality protocol utilizing distributed key management features. This mechanism allows the user to keep his or her decryption key shared among several n servers in such a way that when the user wants to decrypt a given encrypted text, the user would have to interact with a single server (the gateway) to obtain the matching plaintext while none of the servers (including the gateway) gets any information about the plaintext. Col. 4, lines 5-14. U.S. Pat. No. 5,996,011 to Humes discloses a system and a method for filtering data received over the Internet by a client computer. The system restricts access to objectionable or target data received by a client computer over an Internet by a web server by filtering objectionable data from the data received. The Humes '011 system filters the data “on the fly.” Further, the Humes '011system can be applied to process any type of target data from the data received and displayed to the user. Col. 2, lines 32-44. If the web page requested by the user contains only a minimum amount of objectionable or target data, the user receives only a portion of the filtered web page for viewing. Hume '011 also provides that if the web page contains a large amount of objectionable material, the system blocks the entire display of the web page on the user's computer monitor. Col. 2, lines 56-62. Hume '011 provides three levels of filtering. At the first level, if the domain name contains objectionable words or material, the initial download from the domain is blocked. At the second level, the text in the download is filtered and objectionable words are replaced with a predetermined icon, for example, “----”. Col. 3, lines 32-35. The filter uses a dictionary. Col. 3, lines 45-48. The filtered out words are counted. If the final score of “filtered out” material exceeds a predetermined threshold, the entire page is blocked from the user's view. Col. 4, lines 2-4. U.S. Pat. No. 5,905,980 to Masuichi, et al., discloses a document processing apparatus for processing various types of documents, a word extracting apparatus for extracting a word from a text item including plural words, a word extracting method used in the document processing apparatus, and a storage medium for storing a word extracting program. Extracted words are associated with other words via an algorithm. The extracted words and associated words are used as a search index for the document. U.S. Pat. No. 5,996,011 to Humes discloses a computer based system and method for filtering data received by a computer system, and in particular, for filtering text data from World Wide Web pages received by a computer connected to the Internet, for purposes of restricting access to objectionable web sites. U.S. Pat. No. 6,148,342 to Ho discloses a system for managing sensitive data. The system prevents a system administrator from accessing sensitive data by storing data and identifier information on different computer systems. Each query from a user's terminal is encrypted using two codes, the first code readable only by an identifier database and a second code readable only by a data access database. The data is routed from the user's source terminal to the identifier database at the first computer. The first computer/identifier database first verifies the user's ID and the security clearance for the requested information and substitutes a second internal ID to the data packet/query. The modified query is then presented to the data access database (the second computer) and, subject to a second security clearance, the response to the data query is sent back to the user's source terminal. A publication entitled “Element-Wise XML Encryption” by H. Maruyama T. Imamura, published by IBM Research, Tokyo Research Laboratory, Apr. 20, 2000 discloses a protocol or process wherein certain parts of an XML document are encrypted and the balance of the plaintext is not encrypted. The protocol is useful in three party transactions, for example, when a buyer sends an order in an XML document to a merchant which contains the buyer's credit card information. The credit card information is sent to a credit company and the merchant does not need to know the credit number as long as he obtains clearance or authorization from the credit card company. Another instance is an access control policy which requires a certain part of an XML document to be readable only by a privileged user (for example, a manager could access the salary field in an employee records but others could only access name, phone and office fields). The Imamura article discusses encryption protocol, the delivery of keys and the utilization of compression. The article does not discuss separate storage of the critical data apart from the plaintext of the XML document. The Ingrain i100 Content Security Appliance product brochure, available in June, 2001, discloses a system coupled to multiple web servers (computers) to accelerate secured transactions between multiple client computers (over the Internet) and prevents Secure Sockets Layer SSL performance bottlenecks by performing high-performance SSL handshakes and encrypting all data sent to back end servers using long-lived SSL session. An article entitled “Survivable Information Storage Systems” by J. Wylie M. Bigrigg, J. Strunk, G. Ganger, H. Kiliccote, and P. Khosla, published August, 2000 in COMPUTER, pp. 61-67, discloses a PASIS architecture which combines decentralized storage system technologies, data redundancy and encoding and dynamic self-maintenance to create survivable information storage. The Bigrigg article states that to achieve survivability, storage systems must be decentralized and must spread information among independent storage nodes. The decentralized storage systems partition information among nodes using data distribution and redundancy schemes commonly associated with disc array system such as RAID (redundancy array of independent discs) insuring scalable performance for tolerance. P. 61. Thresholding schemes—also known as secret sharing schemes or information disbursal protocols—offer an alternative to these approaches which provide both information confidentiality and availability. These schemes and codes, replicate, and divide information to multiple pieces or shares that can be stored at different storage nodes. The system can only reconstruct the information when enough shares are available. P. 62. The PASIS architecture combines decentralized storage systems, data redundancy and encoding and dynamic self-maintenance to achieve survivable information storage. The PASIS system uses threshold schemes to spread information across a decentralized collection of storage nodes. Client-side agents communicate with the collection of storage node to read and write information, hiding decentralization from the client system. P. 62. The device maintains unscrubable audit logs—that is, they cannot be erased by client-side intruders—security personal can use the logs to partially identify the propagation of intruder-tainted information around the system. P. 63. The article states that, as with any distributed storage system, PASIS requires a mechanism that translates object names—for example file names—to storage locations. A directory service maps the names of information objects stored in a PASIS system to the names of the shares that comprised the information object. A share's name has two parts: the name of the storage node on which the share is located and the local name of the share on the storage node. A PASIS file system can embed the information needed for this translation in directory entries. P.63. To service a read request, the PASIS call client (a) looks up in the directory service the names of the n shares that comprise the object; (b) sends read requests to at least m of the n storage nodes; (c) collects the responses and continues to collect the responses until the client has collected m distinct shares; and (d) performs the appropriate threshold operation on the received shares to reconstruct the original information. P. 63. The p-m-n general threshold scheme breaks information into n shares so that (a) every shareholder has one of the n shares; (b) any m of the shareholders can reconstruct the information; and (c) a group of fewer than p shareholders gains no information P. 64. Secret-sharing schemes are m-m-n threshold schemes that trade off information confidentiality and information availability: the higher the confidentiality guaranty, the more shares are required to reconstruct the original information object. Secret sharing schemes can be thought of as a combination of splitting and replication techniques. P. 64. The article discusses the technique of decimation which divides information objects into n pieces and stores each piece separately. Decimation decreases information availability because all shares must be available. It offers no information theoretic confidentiality because each share expresses 1/n of the original information. P. 64. Short secret sharing encrypts the original information with a random key, stores the encryption key using secret sharing, and stores the encrypted information using information disbursal. P. 64. An extension to the threshold schemes is cheater detection. In a threshold scheme that provides cheater detection, shares are constructed in such a fashion that a client reconstructing the original information object can tell, with high probability, whether any shares have been modified. This technique allows strong information integrity guarantees. Cheater detection can also be implemented using cryptographic techniques such as adding digest to information before storing it. P. 65. For the highest architecture to be effective as possible, it must make the full flexibility of threshold schemes available to clients. The article believes this option requires automated selection of appropriate threshold schemes on a per object basis. This selection would combine object characteristics and observations about the current system environment. For example, a client would use short secret sharing protocol to store an object larger than a particular size and conventional secret sharing protocol to store smaller objects. The size that determines which threshold scheme to use could be a function of object type, current system performance, or both. P. 67. The MAIL sweeper and MIME sweeper programs by ReSoft International uses a keyword search engine to review e-mails for certain words or phrases. IF the e-mail does not clear the filter, the addressee data must clear a data base check to protect the privacy and/or confidentiality of the e-mail data. See re-soft.com/product/mimesweep. The Aladdin eSafe Appliance restricts outgoing e-mails from sending classifier or prohibited content. See aks.com/news/2001/esafe. With respect to GPS or global positioning systems, U.S. Pat.

No. 5,757,916 to MacDoran disclose the use of GPS triggered systems which deny access to information when that information is requested by a portable computing device, or limit the delivery of information to a portable device based upon the location of the device obtained from a GPS locator chip or system. Encryption of data to and from GPS located devices is also dislosed in one or more of the GPS references. OBJECTS OF THE INVENTION It is an object of the present invention to provide a data security system, an information processing system and a method for securely storing data and rebuilding that data in the presence of an adequate security clearance. It is another object of the present invention to provide a method for securing data on a single personal computer (PC), on a plurality of computers linked together through a local area network (LAN) or a wide area network (WAN) or the Internet. It is a further object of the present invention to provide a method for securing data utilizing a client-server computer system. The client-server computer system may be implemented over the Internet. The security system may be provided to the public, to government or to private entities as an Application Service Provider or ASP over the Internet. It is a further object of the present invention to provide a method for securing data which is highly flexible and programmable by a user. It is an additional object of the present invention to enable the user to establish (a) the scope of the security sensitive words, characters or icon, data objects, (b) the future use (or destruction or encryption) of a filter enabling extraction of security sensitive data, (c) the selection of storage locations (local, removable, in an LAN, a WAN or on the Internet) for extracted data and remainder or common data and (d) one or multiple levels of security limiting full reconstruction and enabling partial reconstruction of the extracted data and the remainder or common data. It is another object of the present invention to establish and manage the separation of user-based communities of interest based upon crypto-graphically separated, need to know security levels. It is another object to provide an adaptive system responsive to hacking attempts and hacking attacks. These steps may be completely automated (after some parameters are set or programmed by a system administrator), may be fully programmable by the user, or may be a combination of automated and manual controls implemented by the systems administrator and/or the user-client. It is an object of the present invention to parse, disperse and reconstruct the data or data object thereby enabling secure storage of the data. For example, financial data maintained by an institute, can be parsed with an algorithm, the parsed segments dispersed off-site and away from the financial institute, and, upon appropriate security clearance, the dispersed data can be reconstructed to duplicate the data. Large distribution of parsed data is contemplated by this aspect of the invention. The original data remains stable, operable and immediately useful. The securing dispersed data is a back-up of the original data. It is a further object of the present invention to secure e-mail data transmissions and web browser transmissions by extraction of security sensitive data, facilitating the remote storage of said data and sending remainder data to the e-mail addressee or the recipient. It is another object of the present invention to use fine-grained selection of security critical data, extraction and encryption and separate storage of the secured data. The parsing or filtering of plaintext, data object, file or data stream thereby bridges the gap between full encryption of the plaintext etc. and no encryption. The present system is therefore a more efficient use of processing speeds, times, and storage resources. It is a further object to create a credit card number or financial data scrubber. The scrubber may be employed to remove any security critical data. It is another object of the present invention to permit the user to decide on and select a level of risk he or she believes appropriate by selecting no, minimal, intermediate or maximum levels of data security. It is another object of the present invention to permit the user to access data security risks, access data processing resources (processing time, storage facilities, data access time, etc.) and select a security level which balances risks and resources. It is a further object of the present invention to secure files and data objects in portable computing devices. This object is accomplished, in whole or in part, by the system or method which extracts, disperses, via a controlled release of data segments to storage locations, and permits reconstruction utilizing security protocols to provide a security system for data. It is another object of the present invention to permit the scrubbing security icons from maps, credit card data or financial data from text, a data object or data stream. It is a further object of the present invention to provide a method, process and system for handling sensitive words, characters and data objects (“words/objects”) in a MILS or multiple independent levels of security which MILS systems are currently used by various governmental entities. It is an additional object of the present invention to modify the existing separated network, break free of the prior art constraints, and enable collaborative sharing and editing of documents across multiple security levels. It is another object of the present invention to provide cross domain exchanges of documents and permit collaboration on cross-domain basis. It is a further object of the present invention to (a) permit multi-level documents, that is, single documents which contain multiple sections of varying classification and compartmentalization; (b) promote secrecy whereby users may never view sections of documents for which they do not have clearance or approval; (c) enhance editing, that is, to save a document without disturbing sections of the document for which the editing party does not have sufficient clearance and approval; and (d) provide a high level of assurance in that the solution is certifiable for deployment in secret and below environments. It is an additional object of the present invention to deploy the inventive solution to potential applications in a wide range of public and commercial settings. For example, patient records have stringent requirements on releasability, yet multiple individuals have needs to access and update information. Similarly, universities require confidentiality of student records, and grades, again with many access roles defined. In the commercial world, inter-corporate collaboration can be significantly enhanced through the use of shared documents that limit information exposure, from confidential comments, through proprietary information, to enforcing Chinese wall style integrity policies. It is a further object of the present invention to provide an adaptive filter which can be built for single or multiple uses by (a) accepting a base set of security sensitive words, characters, icons and/or data objects and then (b) building a filter which identifies the sensitive words/objects in the compilation of additional data (typically networked to the user's filter generator), and retrieves contextual, semiotic and taxonomic words/objects from the additional data compilation that are related to the sensitive words/objects. It is an additional object of the present invention to provide an adaptive filter that can be used to defeat inference engine attacks on the secured document by construction the filter at each security session or periodically. It is another object of the present invention to provide an adaptive filter, an editor and in general a security system which represents multiple layers of defenses in depth. It is a further object of the present invention to provide a basic editor which output matches the current protocols for various security levels, which can be configured to match security concerns with compliance with law, regulation or policy, privacy, national, organizational or private security concerns, which can be added to the adaptive filter, and which provide the user with choices of secure document storage, dispersion, survival and “pay per view” or the purchase of sensitive word/objects to complete a partially re-assembled document. It is a further object of the present invention to provide an inventive system that adopts an information rights management approach rather than limiting access to information due to the ownership of the network. It is an additional object of the present invention to provide a system which is decentralized and distributed in a coordinated environment wherein different entities can share information and which facilitates the sharing of all information across all levels of security and provides an automated enforcement of policy. SUMMARY OF THE INVENTION The method for securing data in a computer system in one embodiment includes establishing a group of security sensitive words, characters, icons, data streams or data objects, filtering the data input from a data input device and extracting the security sensitive data. The extracted data is separated from the remainder data and is separately stored. In one embodiment on a personal computer (PC) system, the extracted data and the remainder or common data is stored in different, distributed memory segments. In a network implementation, the extracted data may be stored in one computer and the remainder or common data may be stored in another computer. In a client-server implementation, the server may direct storage of the extracted data to a different location than the remainder data, either on the server or on a further memory system (computer) interconnected to the server or on the client computer and in distributed memory segments. A map may be generated by a software module or sub-system indicating the location of the extracted data and the remainder data in the network. The filter may be destroyed (via a deletion routine) or may be retained for future use by the user. If retained, encryption is preferred. The map may be stored on the client computer or the user's PC or may be stored on the server. Copies of the map may be removed (deleted) from the user's PC or the client computer. The map may be encrypted. The extracted data and/or the remainder data may be removed (deleted or scrubbed) from the originating computer. Encryption can be utilized to further enhance the security levels of the system. All transfers of the filter between the client to the server may be encrypted, and all data (whether extracted data or remainder data) may be encrypted prior to storage in the distributed memory. Any transfer of extracted data or remainder data or maps or filters may include an encryption feature. Reconstruction of the data is permitted only in the presence of a predetermined security clearance. A plurality of security clearances might be required which would enable a corresponding plurality of reconstructing users to view all or portions of the data. Persons with low level security clearance would only be permitted to have access to low level extracted data (low level security sensitive data) and the common data. Persons with high level security clearances would be pemitted access to the entire document reconstituted from the extracted data and the remainder data. A computer readable medium containing programming instructions carrying out the methodology for securing data is also described herein. An information processing system for securing data is also described. In another embodiment, the method for securing data in a computer network and transparently establishing and managing the separation of user-based communities of interest based upon crypto-graphically separated, need to know, security levels, by necessity, utilizes communities of interest representing a plurality of users having corresponding similar security levels, each with a respective security clearance. In other words, all members of Community A have the same security level and security clearance, which is different than the users of Community B which have a different security level and security clearance. The method and the computer media containing programming instructions includes filtering data from the data input computer, extracting security sensitive words, phrases, characters, icons, or data objects and forming subsets of extracted data and remainder data. The subsets of extracted data are stored in one or more computer memories in the network identified as extracted stores. The remainder data is also stored in the network if necessary. Reconstruction of some or all of the data via one or more of the subsets of extracted data and the remainder data is permitted only in the presence of a predetermined security clearance from the plurality of security levels. The cryptographically separated, need to know, security levels correspond to respective ones of the plurality of security levels and the method includes, in one embodiment, encrypting subsets of extracted data with corresponding degrees of encryption associated with the plurality of security levels. During reconstruction, all or a portion of the plaintext data is decrypted only in the presence of the respective security level. The information processing system which secures data per the community of interest security level in the includes a data filter for the data input from the data input computer which extracts the security sensitive words, phrases, icons or data objects. A system and a methodology for storing the subsets of extracted data and remainder data is provided and a compiler permits reconstruction of some or all of the plain text data in the presence of an appropriate security clearance level. Multiple level encryption in one document is also available. An adaptive method of securing data responsive to a plurality of hacking events utilizes a hacking monitor which generates a corresponding plurality of hack warnings dependent upon the severity of the hacking attack. Based upon respective ones of the hacking or hack warnings, data is filtered to extract security sensitive words, phrases etc. and the extracted data and the remainder data (if necessary) is stored based on the degree of hack warning. Reconstruction is permitted of some or all the data utilizing the extracted data and the remainder data only in the presence of the predetermined security clearance level. Automatic reconstruction is permitted after the hack attack terminates. The method sometimes includes encrypting extracted data dependent upon the degree or severity of the hack warning and decrypting that data during reconstruction. A computer readable medium containing programming instructions similar to the method is also provided. The information processing system includes a filter which is adjusted based upon the degree of hack warning to extract security sensitive words. A storage system stores extracted data and remainder data (if necessary) based upon the level of the hack warning and a compiler is used to reconstruct the data in the presence of the appropriate security clearance level. The parsing and dispersion aspects of the present invention enable the user to parse, disperse and reconstruct the data or data object thereby enabling secure storage of the data. The original data may be maintained in its original state and stored as is customary, encrypted or destroyed. For example, financial data may be maintained by an institute in its original state, and a copy thereof can be parsed with an algorithm, the parsed segments dispersed off-site, (that is, separated and stored in extract and remainder stores or computer memories), away from the financial institute, and, upon appropriate security clearance, the dispersed data can be reconstructed to duplicate the data. Large distribution of parsed data is contemplated by this aspect of the invention. The original data remains stable, operable and immediately useful in its stored location. The secured and dispersed data is a back-up of the original data. Destruction of the original source is also an alternative embodiment. Another embodiment of the present invention operates in an e-mail or a web browser environment. In a specific embodiment, the invention operates as a credit card or financial data scrubber. The e-mail data has one or more security sensitive words, characters or icons and the method or computer program works in a distributed computer system with a remote memory designated as an extract store. The method extracts the security sensitive words, characters or icons from said e-mail data to obtain extracted data and remainder data therefrom. The extracted data is stored in the extract store. The methodology emails the remainder data to the addressee. The addressee is permitted to retrieve the extracted data from said extract store only in the presence of a predetermined security clearance and hence, reconstruct the e-mail data with said extracted data and remainder data. The program and method on the user's e-mail device extracts the security sensitive data, facilitates storage of the extracted data in said extract store and, emails the remainder data to the addressee. Rather than extracting security data, the method and program may parse the data. The method and program for safeguarding data entered via a browser involves extracting security sensitive data, facilitating the storage of such data in the remote store, and forwarding the remainder data to a targeted destination in the distributed computer system. The scrubber may utilize a pop-up window to enable user activation of the scrubber on an email or a web browser communication. In a computer system with a portable computing device, the method secures security sensitive words, characters, icons, data streams or data objects by determining when the portable computing device is within or without a predetermined region and then extracting the security sensitive data from the file, text, data object or whatever. The extracted data is separated from the remainder data and is separately stored either on media in a local drive or remotely, typically via wireless communications network, to a remote store. In a military application, security icons on a map are extracted, remotely stored and therefore access to the secured data is limited geographically and further by password or pass code control. Encryption can be utilized to further enhance the security levels of the system. Extraction may be automatic, that is, when the portable device is beyond a predetermined territory, or it may be triggered by an event, such a “save document” or a time-out routine. Reconstruction of the data is permitted only in the presence of a predetermined security clearance and within certain geographic territories. A computer readable medium containing programming instructions carrying out the methodology for securing data is also described herein. An information processing system for securing data is also described. The present invention can be configured in various forms. The following descriptions discuss various aspects of the invention and further advantages thereof. The present invention enables the user to obtain automatic classification and declassification of documents on the fly. The extraction process downgrades and declassifies documents on the fly (in real time) so that they are useless to unauthorized parties. Presentation by a user of a valid security clearance enables substantially instant and seamless reconstitution of the security sensitive content. The present invention can be configured to automatically secure unstructured documents and freeform documents, for example, e-mail, instant messaging, or Word documents (input documents). The present invention may also be configured to automatically secure structured documents and transactional documents for example, database records or XML documents (input documents). The present invention introduces flexibility into security management, risk management of data, data storage, and data flows and enable automatic responsiveness to threats. The innovation enables automatic response to security challenges and threats. The innovation can maintain, upgrade and downgrade the levels of security through implementation of a leveled granular extraction process and a controlled-release mechanism. Attacks or other external events can trigger a response in the form of higher extraction levels, expanding the type of content extracted, and constricting the release of important and critical data control from storage. How much and what to extract depends on the level of threat or perceived risk. In same manner, the amount and type of content released from storage and reconstituted depends on the level of threat or risk perceived by the system. The system delivers a level of security protection specifically matched to meet security needs as dictated by the changing security threats, environment, policy and organizational needs. The present invention enables a user to introduce and maintain multiple levels and standards of security. It is common knowledge that the highest security is delivered through total separation. Whereas this concept has only been implemented physically or by isolating computer environments, the invention achieves this concept of total separation within open and networked computer environments. The invention can implement a total physical and logical separation of important and critical data from its context and can preclude access to that information without a needed granular access permission. The invention is also effective for sounds and images (data objects or data streams with security words, characters, terms, icons or other data objects). Some aspects of the present invention introduce a new method and apparatus to monitor security sensitive content through a process of analysis and categorization of each word or character, in a document. The invention enables processing of every character, word, number, as they are entered into a document and categorizes each into one of many pre-set categories. Categories can include surnames, locations, currency, defined terminology, and unknown words or phrases. The present invention, in some embodiments, introduces a method and apparatus for plain text extraction and dispersion of security sensitive data. Maximum security with traditional methods encumbers free flow of information and business efficiency. Encryption burdens computer systems with high performance overhead, and its use is limited to the parties who have decryption capabilities. The invention offers a new solution. It enables leveled security in plain-text format, in addition to none, some, or all of pre-existing encryption, decryption, firewalls, and other security infrastructure. The level of security is determined by the extent of the security sensitive items, selection process; the extent of dispersal to various distributed storage locations; the rules for controlled-release from storage; and the access rules governing the reconstitution of extracts into the secured document. In this configuration of the invention, the extractions are dispersed to distributed storage on a granular level. The rest of the document can be stored at its original location and/or other storage locations. Dispersal of extractions introduces new barriers not existing in current security. In certain situations, an attacker has first to find the (encrypted) map to the locations, then locate and access the distributed storage, get the data released from the controlled-release storage, and finally reintegrate the extracts into the appropriate documents. Further, the present invention enables the user to implement a method and apparatus for targeted extraction and encryption of security sensitive items. The extraction capabilities of the system enable different workflow modes. The system enables extraction and encryption of important and critical content. In essence, only the critical content is extracted and/or encrypted, whereas the rest of the document remains as plaintext. This capability enables the following: advantages and flexibility; and the ability to share the document within the organization or transmit it to outsiders while still maintaining security over the most important and critical content of the document. This is an automatic process for controlling the content of outgoing e-mail. The document owner releases the important and critical content by enabling access to it to defined parties at defined times within defined threat modes. The present invention, in some implementations, introduces a method and apparatus for encrypting document or extractions with multiple encryption types. The invention can deliver the highest level of security by using multiple types of encryption (and/or multiple keys) for one line, paragraph or document. Maximum security is delivered through automatic selection of security sensitive items, and encrypting these extractions with one or more types of encryption. The remainder data can also be encrypted. Multiple encryption types within one document statistically precludes deciphering that document regardless of the available computer power. Common encryption methods are vulnerable through existing technologies, social engineering methods, carelessness, and workflow habits. Furthermore, simple encryption becomes more vulnerable (including triple DES) assuming future mathematical breakthroughs or quantum computing. Existing methods to crack block ciphers are being improved to compromise the future AES Rinjdael standard. The present invention also enables the user to configure the system to introduce a method and apparatus for content dispersion. The innovation enables control over specific important and critical content items within the general contents of documents or digital files in a computer or within a network. The immediate controlled-release of those important content items according to specific identification and access criteria proactively safeguards the security and the value of documents or digital files. The content control enables broad dissemination of the digital files in closed networks, as well as open networks including the Internet, without compromising the security of the important and critical information in the digital file. The dispersal channels can include any of all of the following: networks, Internet, Virtual Private Channel. Telephone lines, Optical lines, Wireless, Fax, Documents, Verbal communication. The present invention, when configured in an appropriate manner, introduces a method and apparatus for enhancing the survivability capabilities of an organization and its networks. If networks get damaged, the decryption capability, such as PKI, is likely to be compromised, or at a minimum, suspended. In such instances, the invention enables continuation of work on channels, which need not be secure. In addition, the dispersion of information guarantees maximum partial reconstitution to documents and transactions, or total reconstitution to documents and transactions benefitting from backup at distributed storage facilities. The present invention, in the appropriate environment, introduces a method and apparatus for delivering security for inter-connecting networks. It enables security for closed networks connecting to the Internet and other open networks. The Internet infrastructure and open networks are not secure. Even secured closed networks, such as VPNs, are not secured enough. The critical content of documents is the critical asset of the organization and must be highly secured, with maximum reliability, full transparency and instant accessibility. To remain competitive, organizations must maximize utility of the critical data within their documents, files, databases and servers. The securing of such documents must not be at the expense of compromising the access or processing speed of such documents. The invention enables work in plain text, as well as with encryption. Working in plain text reduces the computing performance overload. Some aspects of the present invention introduce a method and apparatus for delivering information flow control in decentralized environments. Protection of privacy and confidentiality of information represents a long-standing challenge, The challenge has become much bigger with the expansion of the Internet, which has created decentralized networks. Parties, who do not know or trust each other, have to exchange information. The invention enables free flow and sharing of information between parties by removing burdening security restrictions and creating top security with a controlled-release of the security sensitive content in the documents. The technology enables top security through introduction of user and organization's ownership and control of the critical granular data in documents. The system, in certain embodiments, introduces an additional layer of access controls at the granular level of the user document. In order to view the reconstructed critical information the user would need to be verified by additional access controls at the data storage level. The user access code or a physical key enables release of data from the storage. Today's access controls do not stop the user from distributing documents to other parties. The inventions fined grained controlled-release mechanism releases the critical information, only under a required set of circumstances and access validation. The invention enables the user ownership of his security sensitive critical data and conditions for its release and dissemination. The user has the option to hide the critical data through declassification process and release through a reclassification process in which the critical data would be reconstituted in the document. The present invention, when configured by the user, introduces a method and apparatus for delivering compartmentalization of security sensitive content by leveled access to users. The invention creates leveled sharing of information, for example such that persons with level 3 access will have keys for encryption type RSA persons with level access 2 will have access to Blowfish encryption within one document. The present invention, in certain embodiments, introduces a method and apparatus for enabling more use of distributed and dispersed storage including ASPs (application service providers). There is a major human tendency to refrain from sending important documents to web storage locations because of potential security breaches. This cultural issue is both driven by psychological issues and well-founded security concerns. The retention of those documents as is in physical proximity or locked security, provides actual security but precludes gaining any utility from those documents in a functional business setting. Instead the invention enables functional distribution of those documents without the security sensitive data, and a controlled-release of some or all of the extractions in a granular way in order to support business activities while retaining security. The present invention, in certain configurations, introduces a method and apparatus for enabling lower storage costs. The extraction process declassifies and downgrades mission critical documents. The downgrading and transformation of a critical document into a non-critical document, enables storage in less secured and lower cost storage. Taking advantage of this security-initiated, extraction process can yield substantial storage cost savings. The invention enables a high return on investment ROI for system storage cost arbitrage. Splitting the data into critical and non-critical enables 20 to 90% savings on storage cost. The present invention, in certain circumstances, delivers an automated security risk management system that creates added in-depth security defenses at the semantic-level as well as creation of controlled-release mechanisms at the storage-level with significantly reduced performance overhead requirements. Certain embodiments of the present invention present a technology which answers the security demands as required by Committee on Information Systems Trustworthiness of the National Research Council. The Committee's report, Trust in Cyberspace (1999), defines the security paradigms needed for a safe future. The report states: The substantial commercial off-the-shelf (COTS) makeup of a network information systems, the use of extensible components, the expectation of growth by accretion, and the likely absence of centralized control, trust, or authority demand a new approach to security: risk mitigation rather than risk avoidance; technologies to hinder attacks, rather than prevent them outright; add-on technologies and defense in depth; relocation of vulnerabilities rather than their elimination; none of the existing or security technologies addresses these needs in whole. The invention breakthroughs this barrier by providing a single system which implements each one of those four elements in a unified way. The invention controls information flow in centralized and decentralized environments, through controlled-release of information within distributed systems. The present invention can be implemented to enable certain security measures while accommodating the performance needs of a network. The invention provides a method and apparatus to ease overhead performance on congested computer networks. It can adjust the security defenses based on the performance needs of the network. Many security systems overburden the already burdened computing environment in terms of computational overhead, labor, and training requirements. The invention enables to ease the overhead performance of a network by transforming from high overhead performance, encryption methods, and other security methods, to the method presented by this invention. Certain aspects of the present invention minimize the time of exposure of the important content within a document. The invention enables to separate the important content from the rest of the document for substantial periods of time, thereby minimizing substantially the exposure to risk. It is possible for example to extract the important content from the document and release it for reconstitution only when the user will open the document. In such situations the important content could for example be time and unexposed for over 99% of the time and exposed for less than 1% of the time, which lowers the risk substantially. Further, embodiments of the present invention provide a security risk management method and system to minimize security risks. The invention enables minimization of security risks by: Automatic separation and extraction of granular critical data from the core document. Dispersal of the extracted critical data groups to different secured storage locations. Reconstitution of the critical data in document for limited time, to minimize exposure to risk. Partial reconstitution, of the critical data, in core document, through a controlled release of granular critical data. Granular controlled release of data to specific authorized people only. The present invention, in certain configurations, provides a controlled release security mechanism to enable the release of content and granular content from storage locations in a centralized and decentralized environment. The controlled release mechanism enables release of the appropriate content to the authorized party at the right time under the right circumstances. The present invention sometimes provides a security solution against damage by insiders. Studies show that insiders cause 70%-85% of the damage. These nine innovations are described in detail as follows: The invention enables insiders and employees to work with documents while managers and owners control the release of the critical prioritized information. The control is granular, thereby enabling continued work with the rest of the content in the document. The objective is to empower the user with the highest security while enabling him maximum sharing and delivery flexibility. This enables free flow of information between closed networks and public networks, such as the Internet, without compromising the security through extraction of important and critical content. The user can transport documents through various networks and e-mail services knowing that the critical information, which is still under control, and is not compromised. The present invention can be configured to provide an automatic security system in order to overcome human flaws that create security vulnerabilities. Human engineering flaws are the cause of 90% of security vulnerabilities. For example, passwords are exposed through human fault enabling reading of plain text before it is encrypted. The invention enables an automatic process of appropriate response to security threats in an objective way and on an on going basis. Certain aspects of the present invention provide an automatic security system in order to reduce human labor, and training costs. The present invention provides, in one or more embodiments, protection for important granular content within a document. A feature left out in computer development is the protection and automatic protection of granular important content in a document. In every facet of life critical assets are immediately protected. For example, credit cards and cash are protected in a wallet, important items at home are placed in closets, wall units, cabinets and safes. The present system extracts the digital equivalent of these items, e.g., extracts all credit card data, and stores the extracted data in secure location(s). In general, the present invention provides an alternative method to encryption. Mathematical security and encryption could be broken. Discovery of a mathematical equation for a shortcut of the factoring of prime numbers would be make mathematical security and encryption extremely vulnerable. In 1999 a 512-bit RSA key was broken-at that time 95% of keys in e-commerce were 512 bits long. U.S. government 56-bit Data Encryption Standard was cracked in just 22 hours by the Freedom Foundation. 100,000 PCs were connected with a supercomputer which enabled the testing of 245 billion keys per second. The invention, in a larger sense, provides an automated security risk management system. The system automatically responds to attacks by matching the defenses level to the level of threats. The system responds to security threats through the following mechanisms: (1) controlled extraction of sensitive security data: in normal circumstances, extractions will take place according to pre-set rules; in threat situations, additional extractions will take place to deliver higher security; in an attack, additional substantial amounts of critical data will be extracted to deliver the highest security; (2) controlled dispersal to storage locations; in normal circumstances, dispersal to different storage locations according to pre-set rules will take place; in threat and attack situations, more dispersal to more storage locations, via additional communication channels will take place; and (3) controlled release of extracts for reconstitution; controlling amount of extracts released for reconstitution; controlling time of exposure of extracts in reconstitution; limiting access to specific people; and limiting access to specific times. The present invention also defends, in certain embodiments, against devices like keyboard sniffers and mouse sniffers that can read information keyed into the computer and transmit it to an adversary. The invention enables to input security sensitive items through data input devices other than the keyboard. For example credit card numbers can be inputted through a hand held wireless devise. The inputted data would be transferred to storage for possible reconstitution. The present invention can also be configured to defend against devices that intercept electromagnetic signals from computers, monitors, printers, and keyboards. For example the Van Eck receptors which can read information off the screen the display screen. The invention enables separation contents of document into two or more displays thereby limiting the potential damage of electromagnetic eavesdropping. The present invention, in many embodiments, enables the controlled release of data objects, full or partial release of plaintext source documents to persons or organizations with the appropriate security clearances. Another object of the present invention is to enable the control of information flow over a PC, a network, a LAN, a WAN and over the Internet. A further object of the present invention is to enable the interoperability of several secured networks based upon the relative security clearances of each network. It is another object of the present invention to provide a process for synthesizing a document. In one embodiment, the method, program and information processing system secures data, and particularly security sensitive words, characters or data objects in the data, in a computer system with multiple independent levels of security (MILS). Each level of MILS has a computer sub-network with networked workstations. The MILS sub-networks are connected together via security guard computer(s) and each guard computer has separate memories for each level (TS, S, C, UC(or remainder)). The method extracts the security sensitive words/data (a granular action), from the source document for each MILS level, stores the extracted data in a corresponding extract store for each level and permits reconstruction/reassembly of the dispersed data via said extracted data at each said level of said multiple security levels and remainder data only in the presence of a predetermined security clearance commensurate with each MILS level. In another embodiment, the method, program and information processing system involves filtering and securing data (security sensitive words-characters-data objects) in a source document. The adaptive filter uses a compilation of additional data (typically, but not necessarily, provided via a computer network) and identifies the sensitive words/objects in the compilation of additional data, retrieves contextual, semiotic and taxonomic words/objects from the additional data compilation that are related to the sensitive words/objects. A filter is compiled with the retrieved data and the filter is used to extract sensitive words/objects and the retrieved data (words/objects) from the source document to obtain extracted data and remainder data therefrom. The resulting scrubbed document can be pushed or transmitted to others having a need to know or can be dispersed into classified memories unique to each security level. Contextual words related to the security sensitive words/objects are obtained based upon statistical analysis of the additional data compilation. Semiotic words related to the security words are synonyms, antonyms, and pseudonyms, syntactics relative to the target words and retrieved words, and pragmatics relative to the sensitive words and retrieved words as reflected in the compilation of additional data. The taxonomic words, characters or data objects from the compilation of additional data is based upon categorization and classification of the sensitive words/objects as located and as reflected in the compilation of additional data. In another embodiment of the invention, the method, program and information processing system secures data (security sensitive words, characters or data objects) contained in a data source document with an editor. In a simple implementation, the security sensitive words/objects are known and are pre-grouped into subsets corresponding to respective security levels. The program electronically identifies and displays, in situ in the source document, the sensitive words/objects and uniquely displays each subset of sensitive words/objects. Additionally, the system conforms the precursor data document (marked by security subset) to predetermined protocols for each security levels by identifying and displaying in situ adjunctive words/objects. Upon command, the system inserts security level tags corresponding to the plurality of security levels into the precursor data document at or near the identified security sensitive words/objects and adjunctive words/objects. The marked, precursor document is then processed to extract the identified sensitive words/objects and adjunctive words/objects. The stripped or scrubbed data, that is, the extracted data is either separately stored from remainder data (UC unclassified data) or partial versions of the extracted data with the remainder data is stored based upon security levels unique to each partial version. The process may, upon command, insert placeholders into the remainder data which mark the extracted data. This process may be automatic. Further, manual additions to the marked sensitive words/objects is permitted. In a more comprehensive security editor, a method, process and program of securing content data and meta data contained in a document formatted as a document object model (DOM) is provided. The document object model has a blueprint and root, branch and leaf components. The editor maps the root, branch and leaf components of the source document as binary files populated with content data and meta data representing subsets of the document object model blueprint. Security introns and associated content data and meta data are excluded from further processing. The security introns are previously identified with respect to the DOM blueprint (the blueprint provided by the DOM vendor) based upon predetermined informational attributes relative to the document object model. Introns are identified by the organization subject to the security clearance. The method/process/program obtains a security safe document formatted as a safe document object model. Security exons are copied from the content data and meta data binary files into the security safe document (template) formatted as the safe document object model. Thereafter, the system extracts the security sensitive words, characters or data objects from the copied content data and meta data and either stores the extracted data separately from remainder data or stores partial versions of the extracted data with the remainder data based upon security levels unique to each partial version.
