System and method of secure touch screen input and display

BACKGROUND OF THE INVENTION

[0002] Electronic commerce is achieving widespread use. Transactions are performed everyday over the Internet and through point of sale (POS) or bank systems. Such transactions are typically performed after the person requesting access to some information is authenticated and access is given to that person's private information, such as financial, medical, or other type of restricted records. Present systems are designed to maintain the integrity of the user's credit card, debit card, and account number. However, no measures are taken to ensure the secure authentication of the user in order to prevent unauthorized access by a potential thief.

[0003] Presently, applications providing access to sensitive information are based upon information that a potential thief may appropriate with relative ease. For example, some of the information presently required to grant access to sensitive material, such as a person's Social Security Number, date of birth, or mother maiden's name, is readily available. Once a potential thief collects any two pieces of this information, the thief may obtain access to the person's financial, medical, or other private information. In addition, most secure access systems are set up to divulge a person's entire file, once they receive the appropriate password and/or correct answers to the security questions. Therefore, a potential thief may steal the person's identity and ruin that person's credit.

[0004] Further, “heads up” display devices on windshields of vehicles typically operate by displaying information for the user. These heads up display devices do not have the ability to receive information entered by the user. Additionally, these heads up display devices also do not recognize each unique user.

SUMMARY OF THE INVENTION

[0005] A system and method for viewing, entering, and editing information through a transparent screen are described. The invention allows a user to interactively view, enter, and edit information on a transparent window. In one embodiment, the window display device includes a transparent media configured for allowing the user to see through the transparent media; a display module coupled to the transparent media wherein the display module is configured for displaying information to the user; and an input module coupled to the transparent media wherein the input module is configured for receiving an input from the user, wherein the user is capable of viewing through the transparent media while viewing the information.

DETAILED DESCRIPTION

[0014] In the following descriptions for the purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that these specific details are not required in order to practice the present invention. In other instances, well-known electrical structures or circuits are shown in block diagram form in order not to obscure the present invention unnecessarily.

[0015] A system and method for secure touch screen input and display is enabled through a secure transactional system between different access points are described below. The invention allows a user to utilize a window interface both for display and entry of information. This window interface includes a “heads up” display concept enabled in applications such as vehicle windows, home windows, business windows, interior store windows at a mall, and the like. In one embodiment, the invention also allows for user authentication through biometric identification. In one embodiment, the invention operates in conjunction with a secured transaction exchange, controlled content access, and the like.

[0016] Security of the user's identity may be achieved in a variety of ways. In one embodiment, a single trusted location. For example, a transaction privacy clearing house (TPCH) contains user data. The user interfaces with the TPCH using the user's transaction device. The user therefore does not fill out online the electronic purchase forms at every product vendor's website. The TPCH acts as a financial transaction middleman, stripping off user identity information from transactions. As a result, the user's private information is not stored in several databases across the Internet and in private business networks. The secure locations where the financial data is stored minimizes the possibilities that hackers can access the data or accidental releases of the data can occur. In one embodiment, multiple secure locations are utilized for storage to prevent theft of confidential information.

[0017]
FIG. 1 is a simplified block diagram of one embodiment of a secure transaction system, which may be used in electronic commerce. As illustrated in FIG. 1, in this embodiment, a transaction privacy clearing house (TPCH) 115 interfaces a user (consumer) 140 and a vendor 125.

[0018] In this particular embodiment, a personal transaction device (PTD) 170, e.g., a privacy card 105, or a privacy card 105 coupled to a digital wallet 150, is used to maintain the privacy of the user while enabling the user to perform transactions. The personal transaction device 170 may include a window interface, a privacy card, a digital wallet, a point of sale terminal, a laptop computer, a desktop computer, a PDA, or any other device under the control of the user 140.

[0019] The personal transaction device 170 provides an interface for the user to exchange information. This exchange of information may include but is not limited to the user 140 receiving audio and/or visual content, instructions, requests, and the like from the personal transaction device 170. Further, this exchange of information may also include but is not limited to the personal transaction device 170 receiving instructions, payment authorization, authentication, and the like from the authorized user 140.

[0020] In one embodiment, the personal transaction device 170 is a mobile window interface within a vehicle. In one embodiment, the personal transaction device 170 is a fixed window interface within kiosk at a mall. Both the mobile window interface and the fixed window interface may be available for use by the general public if installed on public transportation or in public areas. In one embodiment, both the mobile window interface and the fixed window interface display information to the user and allows information to be entered by the user through the same display. In one embodiment, a user authentication mechanism such as a fingerprint recognition unit or other mechanism may be built directly into the card. In addition, the personal transaction device 170 may also contain wireless data communication, data storage and communication protocols for selectively communicating with outside devices such as a digital wallet described herein, point-of-sale terminal, or personal computer, and digital televisions.

[0021] In one embodiment, the personal transaction device 170 is configured to manage and control access to content and/or transactions received by individual accounts associated with the users of the personal transaction device.

[0022] In an alternate embodiment, account management and control of access to content is achieved through the PTD 170. The PTD 170 may assign particular accounts with varying levels of content access and may place accounts into convenient groupings for account management.

[0023] In one embodiment, the personal transaction device 170 is configured to automatically handle contextual information and share this information with appropriate parties on behalf of the user.

[0024] In an alternate embodiment, the PTD 170 may be any suitable device that allows unrestricted access to TPCH 115. In one embodiment, the personal transaction device 170 may include a full screen that covers one side of the card. Alternately, in one embodiment in which the personal transaction device 170 is one embodiment of a privacy card, the privacy card may be coupled to device such as a digital wallet described herein, that provides a display. In one embodiment, the screen may be touch sensitive and be used for data input as well as output. In one embodiment, a user authentication mechanism such as a fingerprint recognition or other mechanism may be built directly into the card. Furthermore, the privacy card may have a wireless communication mechanism for input and output.

[0025] A variety of user interfaces may be used. In one embodiment, and input device may be incorporated on the transaction device. Alternately, a supplemental input device may be coupled to the transaction device. In one embodiment, an input device may be provided on a digital wallet coupled to a privacy card. User inputs may be provided on the point-of-sale terminals including a personal point-of-sale terminal.

[0026] The personal transaction device information is provided to the TPCH 115 that then indicates to the vendor 125 and the user 140 approval of the transaction to be performed. The transaction device utilizes an identification to maintain confidentiality of the user's identity by applying the transaction device identification and the identity of the entity performing the transaction. Thus, all transactions, from the vendor's perspective, are performed with the transaction device.

[0027] In order to maintain confidentiality of the identity of the user 140, the transaction device information does not provide user identification information. Thus, the vendor 125 or other entities do not have user information but rather transaction device information. The TPCH 115 maintains a secure database of transaction device information and user information. In one embodiment, the TPCH 115 interfaces to at least one financial processing system 120 to perform associated financial transactions, such as confirming sufficient funds to perform the transaction, and transfers to the vendor 125 the fees required to complete the transaction. In addition, the TPCH 115 may also provide information through a distribution system 130 that, in one embodiment, can provide a purchased product to the user 140, again without the vendor 125 knowing the identification of the user 140. In an alternate embodiment, the financial processing system 120 need not be a separate entity but may be incorporated with other functionality. For example, in one embodiment, the financial processing system 120 may be combined with the TPCH 115 functionality.

[0028] In one embodiment, the financial processing system (FP) 120 performs tasks of transferring funds between the user's account and the vendor's account for each transaction. In one embodiment, the presence of the TPCH 115 means that no details of the transactions, other than the amount of the transactions and other basic information, are known to the FP 120. The TPCH 115 issues transaction authorizations to the FP 120 function on an anonymous basis on behalf of the user over a highly secure channel. The FP 120 does not need to have many electronic channels receiving requests for fund transfer, as in a traditional financial processing system. In one embodiment, a highly secure channel is set up between the TPCH 115 and the FP 120; thus, the FP 120 is less vulnerable to spoofing.

[0029] In one embodiment, the TPCH 115 contacts the FP 120 and requests a generic credit approval of a particular account. Thus, the FP 120 receives a minimal amount of information. In one embodiment, the transaction information, including the identification of goods being purchased with the credit need not be passed to the FP 120. The TPCH 115 can request the credit using a dummy charge ID that can be listed in the monthly financial statement sent to the user, so that the user can reconcile his financial statement. Further, the personal transaction device 170 can include functionality to cause the financial statement to convert the dummy charge ID back to the transactional information so that the financial statement appears to be a conventional statement that lists the goods that were purchased and the associated amount charged.

[0030] A display input device 160 (shown in phantom) may be included to enable the user, or in some embodiments the vendor 125, to display status and provide input regarding the PTD 170 and the status of the transaction to be performed.

[0031] In yet another embodiment, an entry point 110 interfaces with the personal transaction device 170 and also communicates with the TPCH 115. The entry point 110 may be an existing (referred to herein as a legacy POS terminal) or a newly configured point of sale (POS) terminal located in a retail environment. The user 140 uses the PTD 170 to interface to the POS terminal in a manner similar to how credit cards and debit cards interface with POS terminals. The entry point 110 may also be a public kiosk, a personal computer, or the like.

[0032] In another embodiment, the PTD 170 interfaces through a variety of interfaces including wireless interfaces such as BlueTooth and infrared transmission; contactless transmission such as FeliCa and AmexBlue; and plugin port transmission such as USB and RS-232C. A stand-in processor 155 (STIP) can interface with the PTD 170 in the event that the connection between the front end and the back end is disrupted for any reason. This way, the PTD 170 can gain authorization for a specified floor limit without necessarily receiving authorization from the back end. Further, this limits the amount of authorization thus minimizing fraud and insufficient funds.

[0033] The system described herein also provides a distribution functionality 130 whereby products purchased via the system are distributed. In one embodiment, the distribution function 130 is integrated with the TPCH 115 functionality. In an alternate embodiment, the distribution function 130 may be handled by a third party. Utilizing either approach, the system ensures user privacy and data security. The distribution function 130 interacts with the user through PTD 170 to ship the product to the appropriate location. A variety of distribution systems are contemplated, for example, electronic distribution through a POS terminal coupled to the network, electronic distribution direct to one or more privacy cards and/or digital wallets, or physical product distribution. In one embodiment for physical product distribution, an “anonymous drop-off point”, such as a convenience store or other ubiquitous location is used. In another embodiment, it involves the use of a “package distribution kiosk” that allows the user to retrieve the package from the kiosk in a secure fashion. However, in one embodiment, the user may use PTD 170 to change the shipping address of the product at any time during the distribution cycle.

[0034] A user connects to and performs transactions with a secure transaction system (such as shown in FIG. 1) through a personal transaction device (PTD) that has a unique identifier (ID). In one embodiment, a privacy card is used. In an alternate embodiment a digital wallet is used. In yet another alternate embodiment, a privacy card in conjunction with a digital wallet are used.

[0035]
FIG. 2 is a simplified block diagram of one embodiment of a privacy card 205 for a personal transaction device. As illustrated in FIG. 2, in one embodiment, the card 205 is configured to be the size of a credit card. The privacy card includes a processor 210, memory 215 and input/output logic 220. The processor 210 is configured to execute instructions to perform the functionality herein. The instructions may be stored in the memory 215. The memory is also configured to store data, such as transaction data and the like. In one embodiment, the memory 215 stores the transaction ID used to perform transactions in accordance with the teachings of the present invention. Alternately, the processor may be replaced with specially configured logic to perform the functions described here.

[0036] The input/output logic 220 is configured to enable the privacy card 205 to send and receive information. In one embodiment, the input/output logic 220 is configured to communicate through a wired or contact connection. In another embodiment, the logic 220 is configured to communicate through a wireless or contactless connection. A variety of communication technologies may be used.

[0037] In one embodiment, a display 225 is used to generate bar codes scanable by coupled devices and used to perform processes as described herein. The privacy card 205 may also include a magnetic stripe generator 240 to simulate a magnetic stripe readable by devices such as legacy POS terminals.

[0038] In one embodiment, biometric information, such as fingerprint recognition, is used as a security mechanism that limits access to the card 205 to authorized users. A fingerprint touch pad and associated logic 230 is therefore included in one embodiment to perform these functions. Alternately, security may be achieved using a smart card chip interface 250, which uses known smart card technology to perform the function.

[0039] Memory 215 can have transaction history storage area. The transaction history storage area stores transaction records (electronic receipts) that are received from POS terminals. The ways for the data to be input to the card include wireless communications and the smart card chip interface which functions similar to existing smart card interfaces. Both of these approaches presume that the POS terminal is equipped with the corresponding interface and can therefore transmit the data to the card.

[0040] Memory 215 can also have user identity/account information block. The user identity/account information block stores data about the user and accounts that are accessed by the card. The type of data stored includes the meta account information used to identify the account to be used.

[0041] In another embodiment, the memory 215 also stores the embedded content received by the privacy card.

[0042] In another embodiment, the memory 215 also stores the account management information such as categories and the account access levels of content.

[0043] In another embodiment, the memory 215 also stores the contextual information gathered by the personal transaction device.

[0044]
FIG. 3 is a simplified block diagram of one embodiment for a personal transaction device 305. As illustrated in FIG. 3, the PTD 305 includes a coupling input 310 for the privacy card 205, processor 315, memory 320, input/output logic 325, display 330, and peripheral port 335. The processor 315 is configured to execute instructions, such as those stored in memory 320, to perform the functionality described herein. Memory 320 may also store data including financial information, ecoupons, shopping lists, embedded content, and the like. The PTD 305 may be configured to have additional storage. In one embodiment, the additional storage is in a form of a card that couples to the device through peripheral port 310.

[0045] In one embodiment, the privacy card 205 couples to the PTD 305 through port 310; however, the privacy card 205 may also couple to the PTD 305 through another form of connection including a wireless connection.

[0046] Input/output logic 325 provides the mechanism for the PTD 305 to communicate information. In one embodiment, the input/output logic 325 provides data to a point-of-sale terminal or to the privacy card 205 in a pre-specified format. The data may be output through a wired or wireless connection.

[0047] The PTD 305 may also include a display 330 for display of status information to the user. In one embodiment, the display 330 is a window display device. The window display device may display information and receive information through a transparent surface. For example, a window display device may be embodied as part of a vehicle windshield. The window display device projects information onto the windshield such that the user may view this information. The window display device also has an input component to receive user entered input through the window display device. For example, the window display device may include a touch sensitive interface, a heat sensitive interface, a light sensitive interface, and/or a motion sensitive interface. In one embodiment, the input component is overlaid and integrated with the area for displaying information to the user.

[0048] The transaction device enhances security by authenticating the user of the card prior to usage such that if that transaction device is useless in the hands of an unauthorized person. One means of authentication is some type of PIN code entry. Alternatively, authentication may be achieved by using more sophisticated technologies such as a biometric solution. This biometric solution can include fingerprint recognition, voice recognition, iris recognition, and the like. In addition, in one embodiment in which multiple transaction devices are used, it may be desirable to configure the first device to enable and program the second device in a secure manner. Thus, the means of communication between the first device in the second device may include mutual device verification such that an unauthorized first device may not be used to enable a particular second device that does not belong to the same or authorized user.

[0049] In one embodiment, the transaction device, point of sale terminals and/or TPCH may function to verify the authenticity of each other. For example the transaction device may be configured to verify the legitimacy of the point-of-sale terminal and/or TPCH. A variety of verification techniques may be used. For example, in one embodiment, the public key infrastructure may be used to verify the legitimacy of the user.

[0050] Communication protocols include those that allow the digital wallet to specify which of several possible data structures to use for a transaction and communication protocols that allow the digital wallet and other devices to securely share data with the transaction device. The transaction device may represent a single account such as a particular credit card, or it may represent multiple accounts such as a credit card, telephone card, and debit card.

[0051] In one embodiment, the transaction device is intended to be the means by which the user interfaces with the invention. In one embodiment, the transaction device stores e-commerce related data on behalf of the user including transaction histories, meta account information needed to carry out a transaction using the transaction privacy clearinghouse function of the system, and various content. In one embodiment, the meta account information may be an abstraction of the user's real identity as opposed to the actual user's name, address, etc. For example, the TPCH keeps records of the user's real bank account numbers, but assigned a different number for use by retailers and point-of-sale terminals. For example, and actual Bank Account No. may be 1234 0000 9876 1423 could be represented as 9999 9999 9999 9999. This number, in association with the transaction card's identification, could enable the TPCH to know that the bank account No. 1234 0000 9876 1423 was actually the account being used.

[0052] The purpose of this data is to abstract the user's identity while at the same time providing the necessary information for the transaction to be completed.

[0053] In one embodiment, the personalization process of the transaction device may be as described below. In this example, the transaction device is a digital wallet. The user turns on the transaction device. This can be accomplished by touching the finger print recognition pad or simply turning a switch. The transaction device performs at start a procedure, and recognizes that it has not yet been personalized. Thus, it first prompt the user to enter the secret pin code. If the pin code entry fails, the user is prompted again. Ideally the user is given a finite number of chances to enter the data. After the last failure, the device may permanently disable itself and thus becomes useless. It may also display a message requesting that the transaction device be returned to an authorized facility.

[0054] Assuming a successful pin code entry, the user may then be prompted to answer several of the security questions which were entered into the transaction device at processing center. Some of these questions might require data entry, and others might be constructed as simple multiple-choice, with both the correct as well as incorrect answers supplied. Assuming successful response to these questions, the user may then be prompted to enter secure personal identification information such as fingerprint data. In one embodiment, in which the fingerprint data is used, the user is prompted to enter fingerprint data by successively pressing one or more fingers against the recognition pad. The device prompt the user for each fingerprint that must be entered, for example, using a graphical image of a hand with the indicated finger.

[0055] The fingerprint data entry process may be performed at least twice to confirm that the user has entered the correct data. If confirmation succeeds, the device writes the fingerprint image data into their write once memory, or other memory that is protected from accidental modification. If confirmation fails, the user is prompted to start over with entry. Failure to reliably enter the fingerprint data after a finite number of tries will result in the device permanently disabling itself, and optionally providing an on-screen message to the user to go to secure processing facility such as a bank to complete the process. After successful personalization, the device is then ready to be used for the initial set of services that the user requested during the registration process. Once the device has been initialized for secure transactions, additional services could be downloaded to the device.

[0056] One embodiment of the system that utilizes a point-of-sale terminal is shown in FIG. 4. In this embodiment, the privacy card 405 interfaces with the point-of-sale terminal 410 and that point of sale terminal 410 communicates with that TPCH 415. That TPCH 415 interfaces with the financial processing system 420, the vendor 425 and the distribution system 430. The point-of-sale terminal may be an existing or newly configured point-of-sale terminal located in a retail environment. The user 440 uses the privacy card 405 to interface to the point-of-sale terminal a manner similar to how credit cards and debit cards interface with point-of-sale terminals. Alternately, a digital wallet 450 may be used by itself or with the privacy card 405 to interface to the point-of-sale terminal 410. Alternately, a memory device may be utilized solely as the interface with that point-of-sale terminal 410.

[0057] One embodiment of the TPCH is illustrated in FIG. 5. In one embodiment, the TPCH 500 is located at a secure location and is accessible to the transaction device. The TPCH 500 functions to provide the user with authorization to perform transactions without compromising the user's identity. The TPCH 500 may be embodied as a secure server connected to the transaction device in some form of direct connection or alternately a format in direct connection over the Internet or point-of-sale network.

[0058] Incoming communications mechanism 505 and outgoing communications mechanism 510 are the means of communicating with external retailers and vendors, as well as the transaction device such as the digital wallet. A variety of communication devices may be used, such as the Internet, direct dial-up modem connections, wireless, cellular signals, etc.

[0059] The TPCH agent 515 handles system management and policy control, informs their core functionality of the TPCH 500. In one embodiment, within the entire system, there is one clearinghouse agent, which resides permanently at the clearinghouse. Among the responsibilities handled by the agent include internal system management functions such as data mining, financial settlement and allocation of payments to internal and external accounts, embedded content management, and registration of new users joining the system.

[0060] The security management functions 520 ensure secure communications among the component internal to the TPCH 500 and the entities external to the TPCH 500. This function includes participating in secure communications protocols to open and maintain secure connections. This ensures that only authorized entities are allowed to access to data and that only authorized transaction devices can execute transactions against a user's account.

[0061] The TPCH agent 515 also provides a direct marketing and customer contact service 525, which in one embodiment is a data access control mechanism and maintain separate, secure access between various client and their databases. The data access control mechanism ensures that vendors have access only to the appropriate data in order to carry out the tasks of the system. One of the key features at the TPCH 500, the ability to carry out focused direct marketing while maintaining the privacy and identity protection of consumer, is handled by this mechanism.

[0062] The TPCH agent 515 can be configured to actively look for content on behalf of the user as well as filter out unwanted incoming information. In one embodiment, the data may be described by XML and the agent may operate via Java applets.

[0063] The window display device is enabled with detection and identification of location-based input such as a global positioning system (GPS) within the display area of the window display device. Technologies such as fiber optics, temperature gradient sensors, and motion detector sensors do not interfere with the transparency of the display/input area yet still detect input by the user.

[0064]
FIG. 6 illustrates one embodiment of a window display device 600. The window display device 600 includes a display component 610 and a entry component 620. In one embodiment, the window display device 600 is transparent. The display component 610 is configured to display information to be viewed by the user. The entry component 620 is configured to accept data entry from the user. The entry component 620 may sense the data entry from the user via a pressure sensor, a heat sensor, a light sensor, an optical sensor, and the like. The display component 610 and the entry component 620 are configured to be transparent such that other than information displayed to the user, the view for the user is transparent. In one embodiment, the entry component 620 is overlaid on top of the display component 610.

[0065] The operation of the system of FIG. 6 while a user interacts with a window display device 600 is described with references to the flow diagram shown in FIG. 7.

[0066] The flow diagram as depicted in FIG. 7 is merely one embodiment of the invention. The blocks may be performed in a different sequence without departing from the spirit of the invention. Further, blocks may be deleted, added or combined without departing from the spirit of the invention.

[0067] In Block 700, information is displayed on the window display device. In Block 710, the window display device verifies the identity of the user by either receiving a token, receiving a PIN, receiving a biometric parameter, or the like. In Block 720, the window display device receives information from the user through an input on the input module. In Block 730, the window display device receives edited information from the user via an input on the input module. In Block 740, the window display device allows the user to view an object through the window display device.

[0068] The window display device integrates the output of information to a user and the interactive input from the user. In one embodiment, the window display device enables information to be displayed, entered, and/or edited by the user. This information may include a PIN number, shipping address, and the like.

[0069] Further, the window display device enables an “on window” viewing and entering of information, wherein the information is displayed and edited in a semi-transparent overlay manner on a physical window or transparent media. This way the display and entry of information does not obstruct the visibility through the window.

[0070] In one embodiment, the window display device enables actual “on screen” location manipulation by the user when viewing, editing, or entering information. For example, multiple display windows may be simultaneously utilized for viewing, editing, and entering information.

[0071] In one embodiment, the window display device also includes an integrated user identification and authentication. The user's identity is validated through a verification process through the window display device by the user entering a PIN number or some form of biometric feedback. Once, the identification of the user has been verified, the identity of the user will determine the level of access to services and/or content that is available through the window display device. In another embodiment, a token may be inserted into the window display device for automatic creation and transmission of a digital certificate.

[0072] The window display device, in conjunction with the secure transaction system described in FIG. 1, has many applications. In one embodiment, a “first time” user may register with the secure transaction system by utilizing the window display device. This registration process is utilized once upon set-up. The registration involves establishing a relationship between the consumer and the token. The token may include a portable storage device such as a Memory Stick™, a portable computer (laptop, PDA, and the like), and the like. In one embodiment, the token is integrated within the window display device. In one embodiment, the initialization involves creating a consumer profile. The consume profile may include payment preferences, payment information, shipping address, and the like. This consumer information may be stored locally on the token or remotely.

[0073] In one embodiment, in the case of a PIN-based token, a secure link to the consumer's identity is make through an association of a unique identification via use of a vehicle's existing buttons. The vehicle's existing buttons may include stereo interface, on-board computer interface, integrated cell phone interface, and the like. In another embodiment, the window display device is utilized to enter the unique identification.

[0074] In one embodiment, the vehicle windshield is utilized as the window display device. The secure transaction system is capable of automatically establishing secure links between the user and the service provider that the consumer has an existing relationship with. The service provider may include an automobile roadside assistance, automatic toll collection, hotel chains, airline reservation/confirmation, navigation assistance, concierge services, and the like. For example, if the secure transaction system with the window display device is integrated with a home security system, the home security system would prompt the consumer through the window display device to identify and/or verify their identity in order to open the garage door and turn off the alarm system when the consumer enters within a predetermined radius of the home. The identification and verification may utilize PIN entry, portable token insertion, biometric identification, and the like.
