Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to enhancing security to transaction and, more particularly, to restricting access of an electronic file at one or more specific locations. 
         [0003]    2. Related Art 
         [0004]    Online transactions are becoming more and more prevalent, with an ever-increasing number of online entities that may or may not have a physical real world counterpart. Furthermore, the services offered by these online entities have been improving as well. The popularity of online transactions is partially attributable to the ease and convenience of making a transaction online instead of at a physical location. It is also safer and more convenient to transfer funds online, since these transactions involve no actual cash. 
         [0005]    As online transactions gain more popularity, the security of documents involved becomes more important. For example, it may be desirable to limit online access to sensitive documents such as mortgage agreements or wills to a small number of individuals who have the right to access these documents. Unfortunately, if these individuals&#39; accounts are hacked, a hacker may be able to gain illegal access to these sensitive documents. 
         [0006]    Therefore, while existing online transaction mechanisms have been generally adequate for their intended purposes, they have not been entirely satisfactory in every aspect. It would be advantageous to add additional levels of security to online transaction mechanisms so that access to sensitive documents is more restrictive. 
       SUMMARY 
       [0007]    One of the broader forms of the present disclosure involves a method. The method involves: receiving a request to access an electronically-stored object from a user; prompting the user to go to a target location; receiving electronic feedback from the user with respect to the user&#39;s location; determining, electronically by a processor and based on the electronic feedback, whether the user has reached the target location; and granting access of the object to the user in response to the determining. 
         [0008]    Another one of the broader forms of the present disclosure involves an apparatus comprising a non-transitory, tangible computer readable storage medium storing a computer program. The computer program has instructions that when executed, perform: receiving a request from a party to access a file stored on a computer server; verifying a location of the party based on electronic communication sent from the party; if the location of the party satisfies a set of predetermined criteria, granting electronic access of the file to the party; and if the location of the party fails to satisfy the set of predetermined criteria, denying electronic access of the file to the party. 
         [0009]    Yet another one of the broader forms of the present disclosure involves a system. The system involves: an computer storage that stores an electronic item; an electronic communications interface that is operable to: detect a request to access the item from an entity; and prompt the entity to go to a target location in response to the request; and a computer processor that is operable to: analyze an electronic feedback from the entity with respect to the entity&#39;s location; make a determination as to whether the entity&#39;s location is sufficiently close to the target location; and grant or deny access of the item to the entity based on the determination.

     DETAILED DESCRIPTION 
       [0013]    It is to be understood that the following disclosure provides many different embodiments, or examples, for implementing different features of the present disclosure. Specific examples of components and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. Various features may be arbitrarily drawn in different scales for simplicity and clarity. 
         [0014]    As the Internet continues to evolve, an increasing number of users may choose to engage in and complete transactions online. These transactions may include financial transactions. For example, a user may want to pay for products or services online. Some of these products or services may involve sensitive documents. For example, the user may be trying to purchase a house, in which case a sensitive document may include a mortgage loan agreement. As another example, the user may be asking an attorney to plan an estate, in which case a sensitive document may include a will. 
         [0015]    Sensitive documents as those described above often times contain highly private data pertaining to the user and/or his family. Therefore, the user may wish to limit access of these documents to authorized individuals only. However, conventional online transaction mechanisms may not offer sufficient secured protection of these sensitive documents. The paragraphs below and the accompanying figures will describe a method and apparatus that offer enhanced security to sensitive documents according to various aspects of the present disclosure. 
         [0016]    To facilitate the ensuing discussions, the following example is used. In this example, a user has requested a service—for example an estate planning service—using an online transaction provider. The user may be a single individual in one embodiment, but may also be an entity such as a business entity in other embodiments. The user may also include a plurality of individuals or entities in further embodiments. The online transaction provider may be any entity that is involved in facilitating the user&#39;s transaction. In some embodiments, the online transaction provider may include a bank with which the user maintains a checking or savings account (e.g., JP MORGAN CHASE®), a credit card company (e.g., AMERICAN EXPRESS®), a third party payment provider (e.g., PAYPAL, INC®. of San Jose, Calif.), or another suitable funding source. In some embodiments, the online transaction provider may also be the entity from whom the user requested service (e.g., an attorney or a mortgage company). 
         [0017]    At some point, the user is notified that one or more sensitive documents associated with the requested service are now ready for viewing.  FIG. 1  shows an example communication interface  40  from an online transaction provider. The interface  40  may include an electronic communication message sent to the user from the online transaction provider. In the embodiment illustrated in  FIG. 1 , the electronic communication message is an email. In other embodiments, the electronic communication message may be a text message or a telephone call. The electronic communication message may contain text stating “Dear Sir, you have recently used our site to request a service. The document involved in the transaction is ready to be viewed. Please confirm your identity before we proceed with your transaction.” The electronic communication message may include a link  50  on which the user can click to confirm his identity. 
         [0018]    Referring to  FIG. 2 , after the user clicks on the link  50 , he is directed to a communication interface  60  of the online transaction provider. The communication interface  60  prompts the user to enter his username and password to access his account. The requirement for a correct combination of username (or login name) and password (or pass code/PIN) may offer a first level of security, in that it is generally able to prevent unauthorized access to the user&#39;s account. However, a hacker with advanced computer knowledge may “crack” the user&#39;s username and password, particularly if the username and password are poorly chosen such that they have low protection strength. 
         [0019]    For example, for reasons of simplicity, a user may choose a username that is merely his name (e.g., JohnDoe) or a simple variation of his name (e.g., JohnDoe123). For the same reasons, the user may also choose a password that is uncomplicated and easy to memorize (e.g., his birthday: 10131975, or commonly chosen passwords: password1, qwerty, etc). In doing so, the user may have inadvertently reduced the protection strength of his username and password and made them easy to be cracked by a hacker. Therefore, although the requirement for a correct combination of username and password affords some level of protection for sensitive documents, it may not be enough, and that additional levels of security may be needed. Such security is offered according to various aspects of the present disclosure, as discussed below. 
         [0020]    Once the user inputs the correct combination of username and password, another communication interface  80  is displayed to the user, as shown in  FIG. 3A . The communication interface  80  informs the user that a list of sensitive documents have been prepared. In the illustrated embodiment, these sensitive documents include a “Last Living Will and Testament,” a “Durable Power of Attorney,” and a “Directive to Physicians.” It is understood that these documents are merely examples, and that the sensitive documents may include other types of documents in other embodiments, such as mortgage loans, lawsuit settlements, divorce agreements, fund transfer receipts, promissory notes, etc. Regardless of the type of document, these documents may be in a digital format and may be stored electronically on a computer server. As such, they may also be referred to as digital/electronic files or digital/electronic objects. In some embodiments, the user may be given partial access to one or more of these documents, for example a preview of these documents where the user can see a table of contents and/or the number of pages of a document. 
         [0021]    The communication interface  80  also instructs the user that, in order to view the documents, he needs to take one of his GPS-enabled (Global Position System) devices to a set of GPS coordinates among a list of coordinates. Each set of GPS coordinates defines a respective target location. For example, a location may be the firm office of the attorney who drafted these documents. As another example, a location may be a bank which provided the mortgage loan. As yet another example, a location may be a public building, such as a police station, a school, or a library. 
         [0022]    The user may have previously been asked to register one of his GPS-enabled devices with the online transaction provider (or with a third party identity verification authority). The GPS-enabled device may be a mobile phone, a tablet, a laptop equipped with a GPS transceiver, a GPS navigator, or another suitable device that transmits GPS signals. In some embodiments, the user may be allowed to register several GPS-enabled devices. When the user arrives at the target location with his GPS-enabled device, the GPS signals emitted by his GPS-enabled device are detected by the online transaction provider (for example through a GPS satellite). Through a computer processor, the online transaction provider analyzes the 
         [0023]    GPS signals received from the user and makes a determination as to whether these signals are consistent with the GPS device(s) previously registered. If so, then the online transaction provider may grant access of the sensitive documents to the user. The user may be able to open, download, or otherwise manipulate the documents. If not, then the online transaction provider may deny access of the sensitive documents to the user and may optionally display a warning message. 
         [0024]    In the manner described above, the locational requirement adds another level of security for the protection of the sensitive documents. For a hacker to be able to gain access to the sensitive documents, not only must he obtain the user&#39;s username and password, but he needs to know which of the owner&#39;s GPS-enabled devices are registered, and he also needs to take actual physical possession of one of these devices to the target location. Short of stealing or robbing the user, it may be quite difficult for the hacker to take physical possession of the GPS-enabled devices, as most hackers tend to operate “behind the scenes.” Therefore, requiring the user to be at a target location with a GPS-enabled device before gaining access to certain documents adds an additional level of security to these documents. 
         [0025]    It is understood that the interface  80  shown in  FIG. 3A  is merely one of the many embodiments suitable for verifying the user&#39;s identity.  FIGS. 3B and 3C  illustrate alternative embodiments for the interface  80 . For example, in the embodiment illustrated in  FIG. 3B , instead of displaying a set of GPS coordinates, the communication interface  80  directly displays an address of the target location to the user, as well as a map corresponding to the address. In other variations of the embodiment illustrated in  FIG. 3B , additional addresses and maps associated with alternative target locations may be displayed to the user as well. In some embodiments, the GPS coordinates and the addresses of  FIGS. 3A and 3B  may contain hyperlinks, such that they will pull up a map when clicked on. 
         [0026]    In the embodiment illustrated in  FIG. 3C , the user interface  80  displays a generic location name to the user rather than a set of GPS coordinates. For example, the generic location may be a hospital, where a doctor needs to view the user&#39;s medical directive. It is understood that a hospital is used merely as an example to indicate a generic location. Other generic locations may include banks, schools, government facilities, parks, etc. 
         [0027]    Although not specifically illustrated herein for the sake of simplicity, it is understood that the communication interface  80  may be implemented differently in other embodiments. For example, the communication interface  80  may display only one target location (or one set of GPS coordinates). In yet other embodiments, the communication interface  80  may display a location that is contextually based. For example, the communication interface  80  may state, “please take your GPS-enabled device to the place where you first met with the attorney.” Such information is known to the user himself, but is not readily known to the general public and therefore not known to the hacker either. Consequently, it may be even more difficult for the hacker to gain access to the sensitive documents. 
         [0028]    In some embodiments, instead of requiring the user to go to a target location, the interface  80  may inform the user that he can stay at (or go back to) his home. Thereafter, he will receive a phone call from the online transaction provider, as the phone number may have been registered with the online transaction provider during account setup. During the phone call, the user may be asked security questions, the answers to which are not generally known to the public. As examples, the security questions may include the user&#39;s wedding date, his favorite TV show, his first car, his first grade teacher&#39;s name, etc. The user may have supplied these answers previously. Once again, this process will thwart a hacker because the hacker would have to go to the user&#39;s home and answer the user&#39;s phone, which involves breaking and entering. In addition, even if the hacker has taken physical possession of the user&#39;s home and/or phone, the hacker would still have to know the answers to the security questions. Since neither of these scenarios is likely, the sensitive documents are afforded good security protection. In another embodiment, if simplicity is desired, the user may be verified through a GPS-enabled device, rather than being verified through a telephone call. 
         [0029]    Though the present embodiment illustrates location-restricted access of sensitive documents by way of GPS signals, it is understood that other mechanisms may be utilized to ascertain a user&#39;s location as well. In one embodiment, the user may be prompted to bring a portable device with network connectivity to one of the target locations. For example, the portable device may be a laptop, a tablet, or a phone. The portable device may be allowed to connect to a network at the target location, so that the portable device is assigned an Internet Protocol (IP) address. The IP address may be received and analyzed by the online transaction provider. Based on the results of the analysis, the online transaction provider may ascertain whether the user has physically arrived at the target location, and consequently whether access to the sensitive documents should be granted to the user. 
         [0030]    In a different embodiment, the user may be prompted to bring a mobile telephone to one of the target locations. Once there, the user&#39;s mobile phone communicates with cell towers nearby (for example through a cellular band or mode). The cell towers can be used to triangulate the user&#39;s position based on communication with the user. In that manner, the online transaction provider may ascertain whether the user has physically arrived at the target location, and consequently whether access to the sensitive documents should be granted to the user. 
         [0031]    In another embodiment, the user may be prompted to bring a device with digital photographing capabilities (such as a digital camera or a camera phone) to one of the target locations. Once there, the user can take a digital picture of the target location and then send the picture (for example through email) to the online transaction provider. In some embodiments, the GPS coordinates of the location may be embedded within the digital picture. The online transaction provider may electronically analyze these pictures, and correspondingly ascertain whether the user has physically arrived at the target location. Based on the analysis results, the online transaction provider may decide whether access to the sensitive documents should be granted to the user. 
         [0032]    In yet another embodiment, the user may arrive at the target location and meet with a person at the target location. The person may be an attorney, a paralegal, a legal secretary, a mortgage loan officer, or another suitable official who can verify the user&#39;s identity in person. After the user&#39;s identity has been verified by such person, the user may be given a security code or a confirmation code. The user may send the security code to the online transaction provider, and if the code is correct, access to the sensitive documents may be granted to the user. 
         [0033]    As discussed above, the user may include more than one individual. Thus, the user discussed above may constitute multiple users or multiple parties in some cases. In embodiments where the user includes two or more users, each of the users may be asked to go to a respective target location. For example, a husband may be on a business trip to Texas, and his wife is in California. While the husband is in Texas, he is prompted that his mortgage loan agreement is ready for viewing. In that case, the husband may be prompted to go to a target location in Texas (for example, a branch of the loan-issuing bank in Texas), and the wife may be prompted to go to a target location in California (for example, a branch of the loan-issuing bank in California) before access to the mortgage loan agreement is viewable by either one of them. 
         [0034]    Other scenarios are possible involving multiple users. For example, in an embodiment, one or more of the multiple users may be prompted to go to the same target location. In another embodiment, only a subset (instead of all) of the users is required to be at their respective target locations before access is granted. In yet another embodiment, different levels of access are granted to different users. For example, the wife in the above example may be allowed to view the document in its entirety, while the husband may be allowed to view only a portion of the document. 
         [0035]    It some embodiments, the access to the sensitive documents may only be granted for a predetermined period of time. For example, once the user has been deemed to be at the target location, and the sensitive documents are “unlocked,” the user may be notified that he only has one hour (or any other suitable amount of time) to download or view the documents. After this time expires, the access to the documents may become restricted again. The time-based restriction to document access in addition to location-based restriction further enhances the security of the documents. 
         [0036]    Returning to the embodiment illustrated in  FIG. 3A , once the user takes his GPS-enabled device to one of the target locations defined by the GPS coordinates, access to the documents is granted. This is indicated in the communication interface  100  illustrated in  FIG. 4 . The same would happen for the embodiment illustrated in  FIG. 3B , after the user takes his GPS-enabled device to a specific text-based or map-based address. For the embodiment illustrated in  FIG. 3C , once the user takes his GPS-enabled device to the generic location such as a hospital, a reverse GPS process is executed to determine if the location the user is at is in fact a hospital. If so, then access to the documents can be granted to the user. It is understood that in some embodiments, a certain predefined tolerance may be built in for the determination of whether the user has in fact arrived at the target location. That is, the user may be within a certain number of feet or meters within the exact target location to be considered physically present at the target location. 
         [0037]    In some embodiments, the interface  80  may contain a confirmation button (or another suitable mechanism), on which the user needs to click to notify the online transaction provider that he has arrived at the target location. The click of the button sends an alert signal to the online transaction provider, which can then begin the verification process. 
         [0038]    In some embodiments, access to all the documents is granted when the user is verified to be at anyone of several locations displayed by the user interface  80 . In other embodiments, access to each document (or to a subset of documents) may be granted at one of the particular locations displayed by the user interface  80 , where access to other documents may be granted at another one of the locations displayed by the user interface  80 . Stated differently, each document (or each subset of documents) may be unlocked at a different one of several locations. 
         [0039]    In one embodiment, the interfaces discussed above and illustrated in  FIGS. 1-4  may be implemented using Internet web pages. In other words, the user may access these interfaces through an Internet web browser, such as Internet Explorer® or Firefox®. In another embodiment, these interfaces may be accessed as an application software, also known as an “App” that may be downloaded in an “App store.” For example, the app stores may be available for an IOS® or Android® enabled smart-phone or tablet. 
         [0040]    It is also understood that the user may be able to change the security level of his account, or the security level of the documents specifically. In more detail, the documents may be designated with a relatively low security level by default, for example a security level that allows access by the user without location-based restrictions. Through a suitable interface similar to those discussed above, the user may be able to change the security level of the documents to a high level that requires the user (or multiple users) to be at the target location(s) before the document can be accessed. 
         [0041]    Conversely, the user may adjust the security level of a document from a higher level down to a lower level, where location-based access is unnecessary, or that it only requires a subset of the criteria discussed above to be met. For instance, in a low security level, a document may be accessed if a subset of a multiple users is present at any one of a plurality of locations, whereas these users may all need to be at their target locations in a high security level. Other differences between high and low security levels are contemplated but are not discussed herein for the sake of simplicity. 
         [0042]    The user may be allowed to change these security levels for the account as a whole (which affects all the documents associated with the account), or for each document individually. The ability to change the security level of the documents (or of the account) gives the user more control and flexibility in managing his documents. 
         [0043]      FIG. 5  is a flowchart illustrating a method  200  for performing an online transaction according to various aspects of the present disclosure. The method  200  includes a block  210  in which a request to access an electronically-stored object is received from a user. In an embodiment, the user includes a plurality of different parties. In an embodiment, the object is a digital file or electronic document stored on a computer server. The file or document may contain private or sensitive information, such that the user wishes to restrict access to the file or document. 
         [0044]    The method  200  includes a block  220  in which the user is prompted to go to a target location. The user may be prompted to take a GPS-enabled device to the target location. In an embodiment, contextually-based instructions are displayed to the user. The contextually-based instructions are known by a correct user but not publicly known. 
         [0045]    The method  200  includes a block  230  in which electronic feedback is received from the user with respect to the user&#39;s location. In an embodiment, the electronic feedback may be one of: a GPS signal, a mobile telephone signal, an IP address, a digital picture of the target location, and a confirmation code. 
         [0046]    The method  200  includes a block  240  in which a determination is made as to whether the user has reached the target location. The determination is made electronically by a processor and based on electronic feedback from the user&#39;s device. The user may be deemed to be sufficiently close to the target location if the GPS coordinates contained in the electronic feedback are within a predetermined threshold of the GPS coordinates of the specified target location. For example, the predetermined threshold may require the received GPS coordinates to be within 0.0001% (or another suitable number) of the specified GPS coordinates. 
         [0047]    The method  200  includes a block  250  in which access of the object is granted to the user in response to the determination made in block  240 . In an embodiment, the access of the object is granted to the user if it has been determined that the user is at the target location. In an embodiment, when the access of the object is granted, it access is limited to a predetermined time period. 
         [0048]    It is understood that the method  200  may include additional steps that may be performed before, during, or after the blocks  210 - 250 . For example, before the access of the object is granted to the user, the user may be required to enter a correct combination of a username and a password. As another example, the method  200  may allow the user to change the security level associated with the user&#39;s account. The security level may specify a manner in which the object can be accessed. As yet another example, the method  200  may offer the user a preview of the object. 
         [0049]      FIG. 6  is a block diagram of a computer system  300  suitable for implementing various methods and devices described herein, for example, the various method blocks of the method  200 . In various implementations, user devices may comprise a network communications device (e.g., mobile cellular phone, laptop, personal computer, tablet, etc.) capable of communicating with a network, and a transaction provider device may comprise a network computing device (e.g., a network server, a computer processor, an electronic communications interface, etc). Accordingly, it should be appreciated that each of the devices may be implemented as the computer system  300  for communication with the network in a manner as follows. 
         [0050]    In accordance with various embodiments of the present disclosure, the computer system  300 , such as a mobile communications device and/or a network server, includes a bus component  302  or other communication mechanisms for communicating information, which interconnects subsystems and components, such as processing component  304  (e.g., processor, micro-controller, digital signal processor (DSP), etc.), system memory component  306  (e.g., RAM), static storage component  308  (e.g., ROM), disk drive component  310  (e.g., magnetic or optical), network interface component  312  (e.g., modem or Ethernet card), display component  314  (e.g., cathode ray tube (CRT) or liquid crystal display (LCD)), input component  316  (e.g., keyboard), cursor control component  318  (e.g., mouse or trackball), and image capture component  320  (e.g., analog or digital camera). In one implementation, disk drive component  310  may comprise a database having one or more disk drive components. 
         [0051]    In accordance with embodiments of the present disclosure, computer system  300  performs specific operations by processor  304  executing one or more sequences of one or more instructions contained in system memory component  306 . Such instructions may be read into system memory component  306  from another computer readable medium, such as static storage component  308  or disk drive component  310 . In other embodiments, hard-wired circuitry may be used in place of (or in combination with) software instructions to implement the present disclosure. 
         [0052]    Logic may be encoded in a computer readable medium, which may refer to any medium that participates in providing instructions to processor  304  for execution. Such a medium may take many forms, including but not limited to, non-volatile media and volatile media. In one embodiment, the computer readable medium is non-transitory. In various implementations, non-volatile media includes optical or magnetic disks, such as disk drive component  310 , and volatile media includes dynamic memory, such as system memory component  306 . In one aspect, data and information related to execution instructions may be transmitted to computer system  300  via a transmission media, such as in the form of acoustic or light waves, including those generated during radio wave and infrared data communications. In various implementations, transmission media may include coaxial cables, copper wire, and fiber optics, including wires that comprise bus  302 . 
         [0053]    Some common forms of computer readable media includes, for example, floppy disk, flexible disk, hard disk, magnetic tape, any other magnetic medium, CD-ROM, any other optical medium, punch cards, paper tape, any other physical medium with patterns of holes, RAM, PROM, EPROM, FLASH-EPROM, any other memory chip or cartridge, carrier wave, or any other medium from which a computer is adapted to read. 
         [0054]    In various embodiments of the present disclosure, execution of instruction sequences to practice the present disclosure may be performed by computer system  300 . In various other embodiments of the present disclosure, a plurality of computer systems  300  coupled by communication link  330  (e.g., a communications network, such as a LAN, WLAN, PTSN, and/or various other wired or wireless networks, including telecommunications, mobile, and cellular phone networks) may perform instruction sequences to practice the present disclosure in coordination with one another. 
         [0055]    Computer system  300  may transmit and receive messages, data, information and instructions, including one or more programs (i.e., application code) through communication link  330  and communication interface  312 .
