Abstract:
The present invention relates to a system allowing computers to be un-connected to the internet or networks while still allowing computers to share data on networks. By creating a one-way secure data link from a primary computer not connected to a network to a second, buffer computer which is connected to networks, the primary computer can distribute data on networks without the risks of being connected to networks.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to any pair of computers which are connected via a one-way secure data link from one to the other such that one of them remains un-connected to the internet and the second receives data securely from the first and the second is connected to the internet. 
       BACKGROUND 
       [0002]    Connecting computers to networks has always contained the risk that they could be penetrated with unwanted code via other computers with which they are connected. However with the advent of the internet this security problem has become extremely serious. Unlike previous networks in which a limited number of computers were connected to each other with the internet or world wide web there are so many computers participating from so many different locations that the security problems have become extreme. In order to enjoy the advantages of sharing data or work product on the internet with other users computer users such as individuals, institutions, governments and businesses connected their computers to the internet. When they did this however they later discovered that by so doing they exposed their computers to various unwanted code from other users on the internet. These forms of unwanted code can penetrate other computers using the internet and perform unwanted functions. Some of these functions include cyberattacks and espionage, cybercrime, cyberwarfare, and other forms of malicious or unwelcome or offensive activities which injure, harm or insult the user. 
         [0003]    This aweful state of affairs was never necessary. If users such as individuals, governments, institutions and businesses had been informed of the possibility of these risks they never need to have connected their computers containing vital or sensitive files or programs to the internet. It was always possible to keep their computers un-connected to the internet but enjoy the advantages of sharing data created by their computers by using a second or buffer computer which was on the internet and then transferring data from the un-connected computer to the buffer computer by a variety of secure external means such as disks or flashdrives. In this way such devices can be loaded with data from the computer un-connected to the internet and then the device connected to the un-secure buffer computer connected to the internet and then the dat loaded from the device into the buffer computer to create a file which can be distributed via the internet. By this means it has always been possible to keep certain sensitive computers un-connected to the internet and yet allow data from those computers to be shared on the internet using a buffer computer. If governments, institutions, businesses and individuals had done this then there would be little if any of the security problems which have been created. 
         [0004]    Although it&#39;s always been possible to avoid internet risks to computers by simply keeping them off the internet and using buffer computers for the internet and to distribute data thereon, there have been two problems. One problem is that this involves having two computers in two different cases. This is not as convenient as having the two computers paired into a single case. Having a single case saves room, is more modular, and allows for ease of use and portability. 
         [0005]    The second problem is the physical inconvenience of relying on external data transport systems such as flashdrives or disks to move data or files from one computer which is un-connected to the internet to the buffer computer which is connected to the internet. My invention solves these two problems by placing the pair of computers in a single case, which can be portable if desired. My invention places both computers as a pair into a single case with a single keypad and screen. The user can use the internet with the buffer computer, which contains no sensitive programs or files. When the buffer computer gets loaded down with unwanted code the user can simply wipe it clean of all code. But within the same case and using the same keypad and screen is also contained the uer&#39;s other computer in which the user maintains his vital programs and files which are not intended to be exposed to the internet. That computer has no network connections but possesses flashdrive, disk or other non-network connectors. That computer can however transport data to the buffer computer so such data can be sent or distributed on the internet by the buffer computer. My invention creates a secure on-way data link which ferries data from the un-connected computer to the buffer computer. This device cannot transfer data from the buffer computer to the un-connected computer. It is not possible for unwanted code to travel from the buffer computer to the un-connected computer. In this manner the un-connected computer. In this manner the un-connected computer remains safe from unwanted code which would otherwise penetrate it from sources via the internet. 
       SUMMARY OF THE INVENTION 
       [0006]    The purpose of the invention is to end all security risks stemming from the internet by allowing computers to share data such as work product made on such computers but without having to be connected to the internet. 
         [0007]    My invention divides all computers into two kinds. One kind are computers in which valuable or sensitive programs and files reside. These computers are used by individuals, governments, institutions, utilities, etc., and businesses for their vital functions. These vital computers should never be connected to the internet, and are not connected to the internet in my invention. The second kind of computer are computers dedicated for internet use. These second computers store no valuable or necessary programs or files. These second computers are used to navigate the internet and use it for many purposes, however it is understood that by doing so that the computer is exposed to all manner of risks from unwanted code from malevolent sources. This second computer will accumulate unwanted code from the internet but from time to time the computer will be wiped clean of all code. 
         [0008]    My invention consists of two computers housed in one case. The computer which is connected to the internet serves the purpose of a mere browser computer which only operates internet functions. The user operates the browser computer or system using the keypad and screen attached to the computer case if the computer is a desktop or other non-laptop or portable computer, or within the computer case if the computer is a portable or laptop system design. 
         [0009]    However within the same computer case is also a second computer which is never connected to the internet. This is actually the primary computer of the user because it is a computer with substantial computing power, speed, memory storage, and other facilities such that it is suitable for use for the user&#39;s many non-internet functions. These functions are conducted by the programs and software the user needs for the computer to conduct the vital functions of the user. These functions relate to everything required of the computer and it&#39;s programs to operate the user&#39;s core needs, be the user an individual, a company, a business, a government, an institution, or any other kind of organization or individual. This primary computer possesses no network connectors, and cannot be connected to the internet. 
         [0010]    The user operates the primary computer for the user&#39;s needed functions and in so doing from time to time creates work product or files consisting of data which the user wants to use the internet for distribution to others or publication. To do this safely my invention possesses a one-way data transfer link from the primary computer to the browser computer. The user simply uses the keypad and screen shared by the two computers, or pair of systems, to operate the one-way data transfer link. The user employs the keypad and screen as controls to load data files from the primary computer into the data transfer device, or ferry. Once the intended files are loaded into the device, or ferry, the device disconnects from the primary computer and travels, or ferries, the data mechanically or electronically to the browser computer system by attaching to it and loading the intended data files into it. Once the browser computer has received the data file then the device, or ferry, disconnects from the browser computer system. Once the ferry device is disonnected from the browser computer system it is automatically wiped clean of all data. Once all data has been cleaned or purged from the ferry device then it moves mechanically or electronically back for re-attachment to the primary computer system so it may receive another load of data for transfer. 
         [0011]    In my invention the primary computer and the browser computer systems share the same screen and keypad. The user can instruct the keypad and other controls on the computer case to switch from one computer to the other. In this system the user can use the browser for the internet functions when desired and use the same keypad and screen to operate the primary computer when needed. My invention can also be configured for larger computers which cannot be fitted into a single case or use a single keypad or screen. My invention applies to all computers of any size or scale in which the primary functions of the user are operated by one or more computers which are dis-connected from the internet but use secure data transfer systems to ferry files from the secure computer system to less secure computers which are connected to the internet or other networks. 
     
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0012]    As stated above, Computer users almost always use the same computer for internet/intranet use as for all their other sensitive or confidential uses. When they use their computers with sensitive files and data stored therein for internet/intranet use they open their sensitive files to examination, corruption or destruction by others who penetrate their computers. The common methods to counter-measure such penetrations such as the use of firewalls and software to counter access of files or disk storage are ineffective and costly. The invention claimed here solves this problem. 
         [0013]    My invention prevents anyone from accessing sensitive files or data on a computer through the internet or other external sources through structural architecture of the computer making protective measures such as anti-penetration software unnecessary. By placing within one computer chassis two independent sets of microprocessors and drives, or systems, which are structurally separate one microprocessor/drive, can be used to store sensitive files and data with no direct connection to the outside through the internet or other means. A second microprocessor/drive unconnected to the first can be used to access the internet and other vulnerable outside means. To allow the user to send data or files from the first, secured system, to the second, unsecured system, a one way data ferry is made. One way of creating a secure data ferry is to load a data drop connected to the secured system which can then be disconnected from it and then travel to the unsecured system, connect to it, and unload or download the data it conveys. Then before the data drop, or ferry, is re-connected to the secured system it can be wiped completely clean so no data from the unsecured system is transferred to the secured system. 
         [0014]    The claimed invention differs from what currently exists. Protective anti-virus, anti-spyware, anti-malware, and all other protective software and firewalls are subject to penetration and countermeasures rendering such protective measures costly, cumbersome and ineffective. The only effective way to prevent sensitive files and data from being accessed from outside sources such as the internet is to use two computers—one for sensitive data and a second for internet use. Then if the user wishes to email or send data from the first computer he must use a flashdrive, disk or other mechanism to selectively transfer particular data from the first to the second so it may be sent out. This architecture is cumbersome and expensive. As well the means for transferring data from the first to the second may be compromised unless conscious actions are taken to make sure the flashdrive or other means is not contaminated by its connection to the second computer. 
         [0015]    This invention is an improvement on what currently exists. Protective anti-virus, anti-spyware, anti-malware, and all other protective software and firewalls are subject to penetration and countermeasures rendering such protective measures costly, cumbersome and ineffective. The only effective way to prevent sensitive files and data from being accessed from outside sources such as the internet is to use two computers—one for sensitive data and a second for internet use. Then if the user wishes to email or send data from the first computer he must use a flashdrive, disk or other mechanism to selectively transfer particular data from the first to the second so it may be sent out. This architecture is cumbersome and expensive. As well the means for transferring data from the first to the second may be compromised unless conscious actions are taken to make sure the flashdrive or other means is not contaminated by its connection to the second computer. 
         [0016]    Software to provide counter-measures to malware, spyware, or other unwanted penetrating code are expensive, troublesome to install and update, and have vulnerabilities rendering them ineffective. The alternative of using two independent computers requires that two different keyboards and screens be used which takes up unnecessary space and is inconvenient relative to using a single keyboard and screen. Then the means employed of transferring data from the non-internet/intranet computer to the one connected to the outside must be consciously wiped clean or disposed of so and new and uncontaminated device may be safely used. 
         [0017]    By placing two independent sets, or systems, of microprocessors and hard drives into one computer chassis, and creating a secure data ferry which is automatically wiped clean and sanitized after each use there are not two different computer keyboards, screens, etc. to be negotiated. As well because the data ferry is automatically wiped clean and sanitized there is no risk that its prior connection to the internet connected unsecured system will contaminate the secured system which contains the sensitive data. 
         [0018]    The Version of the Invention Discussed Here Includes:
       1. secured drive/processor system with accompanying software   2. unsecured drive/processor system with accompanying software   3. data ferry   4. data ferry conveyance mechanism   5. data ferry sanitation device with accompanying software       
 
         [0024]    Relationship Between the Components: 
         [0025]    Number 3 the DATA FERRY is used to store data from the Number 1 SECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE by connecting to it and receiving data from it. Once Number 3 the DATA FERRY has received the data it disconnects from Number 1 the SECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE and Number 4 the DATA FERRY CONVEYANCE MECHANISM physically or electronically moves Number 3 the DATA FERRY and/or it&#39;s contained stored data to connect to Number 2 the UNSECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE where it is available for attachment to emails or other means of transference out of the computer. Once Number 3 the DATA FERRY has unloaded its data to Number 2 the UNSECURED DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE it is disconnected from Number 2 the UNSECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE and then is automatically wiped clean of all data of any kind Number 5 the DATA FERRY SANITATION DEVICE WITH ACCOMPANYING SOFTWARE. 
         [0026]    How the Invention Works: 
         [0027]    The UNSECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE is a data system which can perform any of the applications desired by a computer except for connection to, and exporting data to, the world outside of itself. For that reason it never needs to be cleaned because it will never be accessed or penetrated from outside. When the user wishes to take data from it and send it to others he commands the DATA FERRY [which has been previously cleaned] to attach itself mechanically or electronically to the SECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE and the latter device system loads the DATA FERRY with the desired data. Once the DATA FERRY is loaded with data it disconnects from the SECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE and the DATA FERRY CONVEYANCE MECHANISM physically/mechanically or electronically conveys the DATA FERRY and/or its data to connect to the UNSECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE. Once the UNSECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE has received the data it may use the data for emailing or other transferal functions via internet or intranet or telephonic connection or any other connectivity function which the computer user wishes to perform. By performing this function this way, by this system, the computer user is only exposing the UNSECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE to penetration from outside and corruption or examination of data therein. Only the UNSECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE need be cleaned in order to purge it of unwanted code while the SECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE remains pristine. To assure that the SECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE remains pristine after the DATA FERRY disconnects from the UNSECURED SYSTEM DRIVE/PROCESSOR/ACCOMPANYING SOFTWARE the DATA FERRY is wiped clean of any data by the DATA FERRY SANITATION DEVICE WITH ACCOMPANYING SOFTWARE. 
         [0028]    How to Make the Invention: 
         [0029]    Take the internal mechanisms of two computers: their hard drives and accompanying processors, and assemble them into two independent computing systems installed into a single computer chassis with a single keyboard and screen. Then give each of the two systems of drives and processors its own software so that they can be independently operated from the same keyboard, mouse or screen. Create a data ferry by installing a data memory device between the two systems, and construct a mechanism for the ferry and/or its contained data to be moved or conveyed so as to be connected and disconnected between the two systems. Make sure that the memory device, or data ferry, cannot be connected to both systems at the same time. Design the conveyance for the memory device, or data ferry, between the two systems so that after it has been disconnected from the unsecured system into which it&#39;s data is transferred that it automatically is wiped clean of all data by a device appropriate to do so which itself cannot be corrupted by any data the memory device may contain. 
         [0030]    The two systems with their accompanying software are necessary as is the data ferry/memory device and its conveyance mechanism and the sanitizing device which wipes it clean before it is re-connected to the secure system. None of these parts are optional except for the data ferry sanitizing device if the data ferry is constituted such that it cannot receive data from the unsecured system or the unsecured system is constituted in such a way that it cannot transfer data to the data ferry. 
         [0031]    The data ferry may itself be physically moved between the secured and unsecured systems by the conveyance mechanism. However the same function may be conducted by the data ferry remaining stationary and the data it conveys being transferred to it and then to the unsecured system by means of electrical gates which can be securely opened and shut. For this system to work these gates like the data ferry sanitizing device must be completely independent from the unsecured system, or corruption of the system could be used to control the gates such that they could allow data to pass from the unsecured system via the data ferry to the secured system. No sanitizing device for the data ferry is required if it is constituted to not be able to receive data from the unsecured system or the unsecured system is constituted so it cannot transfer data to the data ferry. 
         [0032]    How to Use the Invention: 
         [0033]    The user or operator would shift back and forth between the two unconnected and independent systems depending on the task performed. When the user wishes the convenience of using a system connected to the internet for purposes which are not sensitive and require no security he may use the unsecured system. He may keep few software packages on the unsecured system and clean it of unwanted code from time to time by wiping its hard drive and other components clean without having to reload many software programs. However when the user wishes to perform tasks for which security is desired and wishes to store software programs which cannot be easily unloaded and reloaded when a hard drive, etc. is cleaned, then the user can use the secured system. Whenever the user wishes to load or transfer data into the secure system he can do so through flash drives or disks for which he maintains discretion and accounting/management. Otherwise there is no way that the secured system can be penetrated or its codes or data accessed by unintended parties. Then when the user wishes to transport data from the secured system to parties outside of his computer he can instruct the data ferry conveyance system to connect the clean data ferry to the secure system so the desired data can be loaded into it. Once the data is loaded into the data ferry it [or its data] is conveyed to the unsecured system, and the data is transferred to it. When the data has been transferred to the unsecured system the data ferry disconnects automatically from the unsecured system and is wiped clean of all data by the sanitizing device. The user can use the transferred data in the unsecured system for transmittal to outside parties via email or any other means the user can instruct the unsecured system to do. 
         [0034]    Additionally: The use of a data ferry as described can be used to transfer data between a secured device and an unsecured device although the devices may not be computers but other forms of electronic devices uses data or signals or information such as radio transmitters or receivers or telephones, etc.
