## Title
Transaction authentication

## Abstract

A biometric token is generated for a user and provided to a user-operated device. A pre-staged transaction is defined by a user and the user supplies the token for association with the pre-staged transaction. Subsequently, a user visits a transaction terminal and a new candidate token is generated from biometric attributes of the user. The candidate token is matched to the token associated with pre-staged transaction to authenticate the user and the pre-staged transaction is processed at the transaction terminal as a completed transaction.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of U.S. patent application Ser. No. 17/243,813, filed Apr. 29, 2021, which is a continuation of U.S. Patent application Ser. No. 16/112,753, filed Aug. 26, 2018, which applications and publications are incorporated herein by reference in their entirety.


BACKGROUND
Technology has advanced consumer transactions in a variety of manners. One of the first conveniences that technology provided was introduced decades ago as Self-Service Terminals (SSTs), which permitted consumers to check out or perform banking transactions without clerk assistance. More recently, mobile phones can be used by consumers to perform Self-Service (SS) checkouts within retail stores or remote from any specific brick-and-mortar stores. In some cases, the mobile phones interact with SSTs at retail locations to perform SS checkouts.
Some transactions raise more security concerns for both the consumers and the retailers than other transactions do. For example, an Automated Teller Machine (ATM—one type of SST) is capable of dispensing currency to consumers. The currency in the ATM and the account balance of a consumer with a financial institution are both at risk of loss when unauthorized withdrawals are performed at the ATM by someone other than the true consumer.
Typically, ATMs provide a variety of security features (hardware and software) to thwart theft from the financial institutions and from the consumers' accounts. For instance, ATMs include encrypted Operating Systems (OSs), secure peripherals that perform independent security operations for each transaction, and secure network connections to financial networks. The consumer performs a transaction by inserting a bank card into a card reader peripheral and providing a Personal Identification Number (PIN) through an encrypted PIN pad at the ATM. Yet, security measures can and are still breached resulting in losses to both the consumer and the financial institution.
A financial institution may also face substantial regulatory liabilities as a result of security breaches of the institution's customer data assets. Thus, institutions do not want to be responsible for centrally housing even more customer information in a perceived effort to improve security because even the best-intended security can be compromised and data centrally stored can result in liability for exposure to the entire institution's customer base.
As more convenience in transaction processing is offered by retailers and financial institutions, additional security measures are needed. Adding secure hardware and software security techniques may be unrealistic for many retailers and, is particularly problematic for financial institutions because legacy security provided in the ATM hardware and software is tightly coupled together, such that one small change to accommodate a new consumer feature can require substantial amounts of hardware and human resource capital outlays.
Consequently, and largely due to security concerns and potential liabilities of financial institutions during a data breach, financial institutions are reluctant and, in some instances, actively resistant to adding any new transaction-based features at their ATMs for consumer convenience and/or to centrally storing additional sensitive consumer data.

DETAILED DESCRIPTION
FIG. 1 is a diagram of a system 100 for transaction authentication processing, according to an example embodiment, according to an example embodiment. It is to be noted that the components are shown schematically in greatly simplified form, with only those components relevant to understanding of the embodiments being illustrated.
Furthermore, the various components (that are identified in the FIG. 1) are illustrated and the arrangement of the components is presented for purposes of illustration only. It is to be noted that other arrangements with more or less components are possible without departing from the teachings of transaction authentication processing, presented herein and below.
As used herein and below, the terms “customer,” “consumer,” and “user” may be used interchangeably and synonymously.
As used herein and below, the term “operator” refers to a customer or a clerk that is operating a transaction terminal for a transaction. That is, the operator is a customer when the transaction terminal is a SST, such as a kiosk or an ATM, and the operator is a clerk assisting a customer with a transaction when the transaction terminal is a Point-Of-Sale (POS) terminal.
The system 100 includes a transaction terminal 110 (hereinafter just “terminal 110”). The terminal 110 including: a peripheral biometric-enabled input device 111 (hereinafter just “input device 111”), a biometric agent 112 (hereinafter just “agent 112”), and a transaction manager 113. It is to be noted that although not illustrated in the FIG. 1, the device also includes one or more hardware processors, volatile and non volatile memory, non-volatile storage, and networking circuitry (such as wired ports and/or wireless transceivers).
The system 100 further includes a server 120 that is networked interfaced to the device 110 (through a wired and/or wireless network connection). The server 120 includes a biometric token generator 121 (hereinafter just “token generator 121”), a biometric registration service 122 (hereinafter just “registration service 122”), and a pre-staged transaction manager (hereinafter just “pre-staged manager 123”). The server 120 also includes, not shown in the FIG. 1, one or more hardware processors, volatile and non-volatile memory, non-volatile storage, and networking circuitry (such as wired ports and/or wireless transceivers).
Moreover, the system 100 includes one or more user-operated devices 130 (hereinafter just “device 130). The device 130 includes a server interface 131 and a biometric token 132 (hereinafter just “token 132”) securely housed in non-volatile storage of the device 130. The device 130 includes, not shown in the FIG. 1, one or more hardware processors, volatile and non-volatile memory, non-volatile storage, and networking circuitry (such as wired ports and/or wireless transceivers).
The system 100 provides mechanisms for a user operating the device 130 to pre-stage a transaction with the server 120 and at a later or subsequent point in time complete processing of the transaction at the terminal 130 utilizing secure biometric authentication processing.
The agent 112, the transaction manager 113, the token generator 121, the registration service 122, the pre-staged manager 123, and the server interface are implemented as executable instructions that reside in a non-transitory computer-readable storage medium on their respective devices and the executable instructions are executed by one or more hardware processors on their respective devices.
Authentication performed at the terminal 110 does not require, in some embodiments, the user to possess any device or authentication card for proper authentication by the terminal 110.
Furthermore, the authentication performed at the terminal 110 does not require, in some embodiments, the user to affirmatively perform any act or action for proper authentication by the terminal 110 other than to make a selection from a user-facing interface of the transaction manager 113.
Furthermore, the server 120 and the terminal 110 do not retain in storage and/or memory of their respective devices any biometric data or the biometric token 132 after a pre-staged transaction is completed as a transaction at the terminal 110. In fact, the biometric data of the consumer is not retained at all except for initial token 132 generation at the server 120, as discussed below and then such biometric data is removed from the server once the token 132 is generated.
The system 100 includes at least two modes of operation: a registration mode and a transaction execution mode.
During the registration mode, a user operates the device 130 to initiate and interact with the service interface 131. The server interface 131 presents interface screens for the user to authenticate to an existing account that the user has with services of the server 120 (such as a financial/banking services) using an authentication mechanism provided by the server 120 for accessing the user's account. The device 130 and the server 120 are placed in network communication with one another for a communication session after successful user authentication with the server 120.
The user selects a biometric token registration option from the interface screens of the service interface 131. The biometric registration service 122 is initiated responsive to the user's selection of the biometric token registration option. The user then selects a biometric token type from available token types presented in the interface screens by the server interface 131. One or more peripherals of the device 130 are activated in response to the selected biometric token type by the server interface 131. Instructions are provided by the server interface 131 for the user to use the peripheral device to capture biometric data from the user. The biometric data is provided by the server interface 131 back to the token generator 121.
The token generator 121 processes the received user's biometric data based on the selected biometric type to produce a unique token 132 that can be relied upon to authenticate the user for transactions at the transaction terminal 110. This token 132 can be in a variety of formats, such as a template that includes readings and/or measurements for biometric attributes of the user. The token generator 121 returns the generated biometric token back to the server interface 131.
At this point in time during the registration mode of operation, the token generator 121 and the biometric registration service 122 deletes and removes from storage and memory of the server 120 the biometric token 132 that was generated and the received user's biometric data. The server 120 does not retain and proactively removes both the generated token 132 and the biometric data associated with the user.
This provides enhanced security to both the user and the enterprise associated with the server 120 because this private information that uniquely identifies the user through biometrics is not centrally stored on the server 120, such that should the server 120 become compromised by an intruder the token 132 and the biometric data are unavailable to the intruder.
The token 132 is received by the server interface 131 from the token generator 121 and obfuscated and/or encrypted in storage of the device 130, such that the token 132 is only accessible to the server interface 131 on the device 130.
It is to be noted that although the processing was described as a token registration process, this is not intended to mean that the server 120 retains any vestiges of the biometric data and the token 132 once the token 132 is generated and provided back to the device 130. That is, the presence of the token, control of the token, and storage of the token remains in control of the user and the user's operated device 130 following the token registration process.
During the transaction execution mode of operation for the system 100, the user accesses the service interface 131 and authenticates to the services of the server 120 using the server's authentication mechanism, which again establishes a communication session and connection between the device 130 and the server 120. (Although, it is to be noted that a user may already be in an authenticated session with the services of the server if the user is prestaging a transaction during a same session that the user first registered for receiving the biometric token 132.)
The user provides input to interface screens for pre-staging a transaction with the transaction terminal 110. The user selects a pre-stage transaction option from the presented interface screens and the server interface 131 initiates the pre-staged manager 123. At least one interface screen may ask if the user wants to use a token 132 for authenticating at the terminal 110 and if selected, the server interface 131 obtains the token 132 from the device 130 and sends the token 132 to the pre-staged manager 123. Assuming the user completed the registration processing, the token 132 is discovered and provided by the server interface 131 back to the pre-stage manager 123. When, the user indicates an option to use the token 132 but the token 132 is not found by the server interface 131, the server interface 131 can call the registration service 122 and perform the registration processing discussed above within a same authenticated communication session between the device 130 and the server.
It is to be noted that the token 132 (provided with the input for a pre-staged transaction in the transaction execution mode of operation for the system) is not the biometric data of the user but is rather a computational template produced from the user's biometric data based on a selected biometric type. Such that, the token 132 if acquired by an intruder over the network wire is useless unless the same processing that was performed by the token generator 121 is also compromised. This provides additional security with respect to the user's biometric attributes. In some cases, before the server interface 131 provides the token 132 to the pre-stage manager 123, the token 132 can be encrypted. Furthermore, the connection between the device 130 and the server 120 is an encrypted communication session that is secure. Additionally, the token 132 can include metadata that identifies the biometric type to which the token 132 is associated, such that the pre-staged manager 123 can identify the proper algorithm and processes for capturing user biometric data once the user is at the terminal 110 and is ready to authenticate for processing a transaction associated with the pre-staged transaction.
The pre-staged transaction manager 123 maintains the token 132 and the pre-staged transaction on the server 120 until the transaction associated with the pre-staged transaction is completed by the transaction manager 113 of the terminal 110 and/or until some predefined event occurs, such as user cancelation through the server interface 131, a preset elapsed period of time from creation of the pre-staged transaction during which the transaction was not processed at the terminal, etc.
When the user appears at the terminal 110 for purposes of performing a transaction representing the pre-staged transaction, the transaction manager 113 includes an operating-facing interface that includes an option for the user to authenticate by biometric authentication. The operator of the terminal 110 selects this option and then another option may appear asking for a selection by the operator of a specific type of biometric authentication. Based on these selected options, the transaction manager 113 initiates the biometric agent 112. The biometric agent 112 activates the biometric-enabled input device of the terminal 110 and provides through the operator-facing interface instructions for the user to interact with the input device so that biometric data can be captured for the user while the user is physically present at the terminal 110. The collected biometric data is then processed to generate a candidate biometric token/template and sent by the biometric agent 112 to the pre-staged transaction manager 123.
The pre-staged transaction manager 123 compares the candidate biometric token/template against a list of current pre-staged transactions that have token associates to locate the user's pre-staged transaction and the user's provided biometric token 132. Assuming a match is achieved, the pre-staged manager 123 provides the pre-staged transaction details for the pre-staged transaction back to the transaction manager 113 along with an identifier for the user and an indication that the user has been successfully authenticated.
The transaction manager 113 processes the pre-staged transaction details to complete the pre-staged transaction as a completed transaction on behalf of the user.
It is noted that this entire process occurring at the terminal 110 is achieved without the user taking any actions related to: inserting a bank card, using a mobile device for presenting a bar code, entering a PIN, or any other action relevant to authenticating the user or identifying the pre-staged transaction. The only action taken by the user (assuming the terminal 110 is a SST and the user is the operator of the terminal 110), is selection from the operator-facing interface an option for the transaction manager 113 to perform biometric authentication (and perhaps selection of a specific biometric type associated with the user's biometric token 132). It is noted that when the terminal 110 is a POS terminal, the 1-2 actions discussed above are taken by a clerk on behalf of the user at the terminal, in such case, the clerk does not require a photo identification for the user and does not even need to ask the user's name; rather, the clerk selects biometric authentication and, optionally, a user-provided biometric type, and then instructs the user to interact with the input device 111 in the manner provided by instructions of the agent 112.
So, a user can authenticate and process a pre-staged transactions with 1 or 2 interface selections and without providing any affirmative authentication information; rather such information is passively acquired from the user through the input device 111.
Once the transaction completes, both the transaction manager 113 and the pre-staged manager 123 delete from memory and storage of their respective devices the candidate token, the token 132, and any of the biometric data collected by the input device 111. Such, that should the user access the server interface 131 for a different pre-staging of a transactions, the server interface 131 needs to resupply the user's token 132 because no vestiges of the token 132 is retained anywhere in the system 100 after the initial pre-staged transaction is processed as a transaction at the terminal 110.
The processing also allows the enterprise associated with the processing to support multiple different biometric types of authentication. That is, the user defines the type of biometric that is to be processed with the token 132. This provides flexibility to the system 100 and provides integration of multiple different biometric types.
As used herein, a “biometric type” refers to the biometric attributes being captured from a user for a specific biometric authentication. Such types can include biometric data gathered for biometric attributes representing, by way of example only, a fingerprint, a palm print, a facial scan, a retina scan, a length of user digits (fingers and thumb) or some combination of user digits, a voice print, etc.
“Biometric data” includes measurements or readings collected from biometric enabled devices, such as shapes of biometric attributes, distances between attributes, patterns in attributes, lengths of attributes, color of attributes, etc.
“Biometric attributes” are the physical features obtained in images, sensor readings, and/or audio by the biometric enabled devices, such as lines and arcs in a user's finger, palm, face shape, voice pitch, thermal temperatures of user's finger/hand, etc.
“Biometric enabled devices” or “biometric input device 111” can include: a touch-enabled display, a fingerprint reader, a camera, a scanner, a retina scanner, a microphone, a video camera, a thermal sensor, etc.
In an embodiment, the biometric token 132 is a template having biometric measurements with respect to one or more of: a user's face, a user's eye, a user's finger or multiple digits of the user, and a voice pattern of the user.
A variety of optional processing can also be provided by the system 100 in some embodiments.
For example, and in an embodiment, when the user provides input for a pre-staged transaction through the server interface 131, the pre-staged transaction manager 123 can generate a unique hash based on pre-staged transaction identifier that is assigned to the user-provided token 132. When the user appears at the terminal 110 for authentication and for processing the pre-staged transaction the pre-staged transaction manager 123 validates the hash value with validation of the candidate token against the token 132. This can provide a second level of authentication, and make the token 132 only usable with a specific pre-staged transaction.
In an embodiment, the token 132 can be sent to the pre-staged transaction manager 123 for association with a pre-staged transaction at a time subsequent to when the user defined and provided the pre-staged transaction through the server interface 131. In one case, the server interface 131 includes scheduling options that the user controls, such that the user can define the date and time that the server interface 131 is to send the token 132 to the pre-staged manager 123 for association with the pre-staged transaction. In another case, the server interface 131 utilizes locations services to identify when the device 130 is within a preconfigured distance of the terminal 110 and when such distance is detected, the server interface 131 sends the token 132 to the pre-staged manager 123 for association with the pre-staged transaction. These embodiments, reduce the amount of time that the server 120 is actually in possession of the token 132, reducing the time during which the token 132 could be potentially compromised from the server 120.
In an embodiment, the device 130 is one of: a mobile phone, a wearable processing device, a desktop computer, a laptop computer, a tablet, and a device that is part of the Internet-of-Things (IoTs).
In an embodiment, the server interface 130 is an enhanced mobile banking application that includes the additional biometric token-based processing discussed herein and above and that includes existing online banking features provided by a financial institution of the user.
In an embodiment, the server interface 130 is provided through a web-based browser of the device with the web pages for the server interface 130 hosted by the server 120.
In an embodiment, the terminal 110 is one of: a SST, an ATM, a kiosk, a teller-operated terminal, and a POS terminal.
In an embodiment, the server 120 is a server that is within a Local Area Network (LAN) with the terminal 110.
In an embodiment, the server 120 is a server that is within a Wide Area Network (WAN) with the terminal 110.
In an embodiment, the interaction between the server 120 and the terminal 110 is achieved through an intermediate LAN server to which the terminal 110 is connected.
In an embodiment, the server 120 is a collection of servers that logically cooperate as a cloud-based server.
In an embodiment, the user-operated device 130 that the user operates to define a pre-staged transaction is different from a second user-operated device 130 that the user operates to initially obtain the token 132 during the registration mode of operation of the system 100. Here, an option on the device 130 is provided to the user for sending the token 132 to the device 130 where the pre-staged transaction is going to be subsequently defined. For instance, the device 130 can be another instance of terminal 110 where the user goes to initially acquire the token 132, once the token 132 is acquired, the user can obtain the token 132 for use in another device 130 in a number of manners, such as: email, text, a Universal Serial Bus (USB) memory device, etc. If the device 130 is another instance of a terminal 110, then after the token 132 is provided to the user's other device 130, the device 130 removes the token 132, such that just the device 130 that the user operates to define pre-staged transactions is the only device 130 that has possession of the token 132.
These and other embodiments are now discussed with reference to the FIGS. 2-4.
FIG. 2 is a diagram of a method 200 for transaction authentication processing, according to an example embodiment. The software module(s) that implements the method 200 is referred to as a “biometric-based pre-stage transaction manager.” The biometric-based pre-stage transaction manager is implemented as executable instructions programmed and residing within memory and/or a non-transitory computer-readable (processor-readable) storage medium and executed by one or more processors of a device. The processor(s) of the device that executes the biometric-based pre-stage transaction manager are specifically configured and programmed to process the biometric-based pre-stage transaction manager. The biometric-based pre-stage transaction manager has access to one or more network connections during its processing. The network connections can be wired, wireless, or a combination of wired and wireless.
In an embodiment, the device that executes the biometric-based pre-stage transaction manager is the server 120. In an embodiment, the server 120 is a cloud-based server.
In an embodiment, the biometric-based pre-stage transaction manager is all or some combination of: the token generator 121, the registration service 122, and the pre-stage manager 123.
At 210, the biometric-based pre-stage transaction manager receives a candidate biometric token for a user from a transaction terminal. This is the processing discussed above with respect to the transaction execution mode of operation for the system, where the pre-staged manager 123 is interacting with the transaction manager 113 of the transaction terminal 110. The interaction between the pre-staged manager 123 and the transaction manager 113 initiated when a user is at the terminal and an operator of the terminal has selected from the operating-facing interface of the transaction manager 113 an option to authenticate via biometric authentication, which triggers processing of the biometric agent 112 to capture biometric data for the user from the input device 111 and generate the candidate biometric token, which is then supplied by the transaction manager 113 to the biometric-based pre-stage transaction manager.
At 220, the biometric-based pre-stage transaction manager matches the candidate biometric token to a biometric token associated with a pre-staged transaction of the user.
In an embodiment, at 221, the biometric-based pre-stage transaction manager searches a list of available and pending pre-staged transactions that have an associated biometric token for a match to the candidate biometric token.
At 230, the biometric-based pre-stage transaction manager authenticates the user for processing the pre-staged transaction at the transaction terminal based on a match between the candidate biometric token and the biometric token assigned to the pre-staged transaction.
In an embodiment, a match can be determined based on a scoring technique such that a score for the biometric token and a candidate score of the candidate biometric token are within a preconfigured tolerance range of one another, such that an exact match does not have to occur for a match to exist. This is particularly useful when the peripheral device of the transaction terminal has different tolerances or quality of data capturing than that which was associated with the device that the user had when initially registering the biometric token. Furthermore, this is useful because biometric attributes of the user can gradually change or be altered such that an exact match is unrealistic.
At 240, the biometric-based pre-stage transaction manager provides the pre-staged transaction back to the transaction terminal for processing on the transaction terminal on behalf of the user.
It is noted that the transaction processed (representing the pre-staged transaction) is processed at the transaction terminal without the user being in possession of any payment card, mobile device, or even being in possession of the biometric token or any other token. The user also does not need any PIN for authentication and for the transaction to be processed. A mere single selection of an option on the transaction terminal by an operator (user or clerk assisting the user) for biometric authentication and passive acquisition of user biometric data is all that is needed for completing the pre-staged transaction. Moreover, because at any given point in time the number of actual users attempting to perform a transaction using the biometric token is relatively low, response time for searching for the biometric match to locate the pre-staged transaction is quick. The entire customer database does not need searched only those pre-staged transactions that have an associated biometric token have to be searched when the user approaches the terminal and selects authenticate by biometrics.
In an embodiment, at 241, the biometric-based pre-stage transaction manager provides pre-stage transaction details including an account identifier for an account of the user with the pre-staged transaction back to the transaction terminal. Receipt of this information is an indication to the transaction terminal that the user is authenticated and is identified for the provided transaction details.
In an embodiment, at 242, the biometric-based pre-stage transaction manager instructs the transaction terminal to delete the candidate biometric token (generated on the transaction terminal) and any biometric collected data by the transaction terminal for the user from the transaction terminal when the transaction is completed. This ensures that only the user on a user-designated device has possession of the user's biometric token once the pre-staged transaction is processed as the transaction at the transaction terminal, and ensures that no device (not even the user-designated device retails any user biometric data.
In an embodiment, at 250, the biometric-based pre-stage transaction manager deletes both the candidate biometric token and the biometric token upon confirmation from the transaction terminal that the transaction was completed on the transaction terminal. Again, no vestiges of the biometric data and biometric tokens remain on the server that processes the biometric-based pre-stage transaction manager and the transaction terminal once the transaction is completed.
In an embodiment, at 260, the biometric-based pre-stage transaction manager performs the registration mode of operation discussed above in the FIG. 1 by the pre-staged manager 123. This occurs at a time prior to the processing identified at 210. Here, the biometric-based pre-stage transaction manager obtains biometric data from a user-operated device, generates the biometric token based on a user-selected biometric type, provides the biometric token to the user-operated device for storage thereon, and deletes the biometric token and the biometric data from the server that processes the biometric-based pre-stage transaction manager.
In an embodiment of 260, and at 270 (representing a portion of the transaction execution mode of operation discussed above with the system 100), the biometric-based pre-stage transaction manager acquires pre-stage transaction details that define the pre-stage transaction from a user and acquires the biometric token with the pre-staged transaction from the user-operated device.
In an embodiment of 270, and at 271, the biometric-based pre-stage transaction manager obtains the biometric token responsive to a user-selected option for biometric authentication with the pre-staged transaction. In other words, the server interface 131 of the user-operated device makes biometric authentication with pre-staged transactions optional and when the user-selects the appropriate option when defining the pre-staged transaction, the biometric authentication transaction processing is made available for that pre-staged transaction.
FIG. 3 is a diagram of another method 300 for transaction authentication processing, according to an example embodiment. The software module(s) that implements the method 300 is referred to as a “biometric-based pre-stage transaction agent.” The biometric-based pre-stage transaction agent is implemented as executable instructions programmed and residing within memory and/or a non-transitory computer-readable (processor-readable) storage medium and executed by one or more processors of a device. The processors that execute the biometric-based pre-stage transaction agent are specifically configured and programmed to process the biometric-based pre-stage transaction agent. The biometric-based pre-stage transaction agent has access to one or more network connections during its processing. The network connections can be wired, wireless, or a combination of wired and wireless.
In an embodiment, the device that executes the biometric-based pre-stage transaction agent is the device 110. In an embodiment, the device 110 is one of: a mobile phone, a wearable processing device, a tablet computer, a laptop computer, a desktop computer, and a device that is part of the IoTs.
In an embodiment, the biometric-based pre-stage transaction agent is the server interface 131.
The biometric-based pre-stage transaction agent interacts with the server 120 (in the manners discussed above with the FIG. 1) and/or the method 200.
At 310, the biometric-based pre-stage transaction agent requests a biometric token from a server. That is, a user is authenticated to an enterprise for services of that enterprise, such as banking services, and the user access the server interface 131 (representing at least a portion of the biometric-based pre-stage transaction agent) and makes a request to register (obtain) a biometric token. This request is identified by the biometric-based pre-stage transaction agent on the user-operated device 130.
In an embodiment, at 311, the biometric-based pre-stage transaction agent identifies a biometric type for the biometric token.
In an embodiment of 311, and at 312, the biometric-based pre-stage transaction agent receives the biometric type based on a user-selected option. The biometric type is one of: a fingerprint, a palm print, an iris scan, a voice sample (for voice-based biometric authentication), and a facial scan.
At 320, the biometric-based pre-stage transaction agent supplies biometric data of a user captured by a peripheral device. The biometric data corresponds to a particular biometric type.
The peripheral device can be any of the peripheral device discussed above, such as: a touch screen display, a fingerprint reader, a camera, a video camera, a microphone, a thermal sensor, a face scanner, and others.
In an embodiment, at 321, the biometric-based pre-stage transaction agent provides instructions on an interface screen of a display to the user that instructs the user on how to interact with the peripheral device to capture the biometric data from the user.
In an embodiment of 321 and at 322, the biometric-based pre-stage transaction agent activates a particular peripheral device based on a biometric type to capture the biometric data of the user.
In an embodiment of 322 and at 323, the biometric-based pre-stage transaction agent provides feedback through the interface for the user to re-interact with the peripheral device when the biometric data is determined to be insufficient for biometric authentication in order to obtain an acceptable new version of the user's biometric data from the peripheral device.
At 330, the biometric-based pre-stage transaction agent receives the biometric token back from the server based on the biometric data supplied at 320.
At 340, the biometric-based pre-stage transaction agent saves the biometric token on a device of the user.
In an embodiment, at 341, the biometric-based pre-stage transaction agent writes the biometric token to a USB device provided by the user and interfaced to the particular device that is executing the biometric-based pre-stage transaction agent. Here, the particular device executing the biometric-based pre-stage transaction agent may be a different device from a device that the user operates to supply a pre-staged transaction and the user acquires the biometric token during the registration mode of operation on the USB device and then subsequently interfaces the USB device to the device that the user accesses for supplying a pre-staged transaction.
In an embodiment, at 342, the biometric-based pre-stage transaction agent sends the biometric token to a user-designated device for the saving of the biometric token. This can be done through wireless transactions, such as Wi-Fi, Bluetooth®, Radio Frequency (RF), and/or Near Field Communication (NFC). This can also be done through SMS text messaging and/or through email. Again, this is an embodiment, where the registration mode of processing is done on a different device from a device that the user operates when supplying a pre-staged transaction.
In an embodiment, at 343, the biometric-based pre-stage transaction agent performs one or more of: obfuscation of a file on the device (the file including the biometric token) and encryption of the biometric token with a private key of the device. This is an embodiment, were the user is operating a same device for the registration mode of operation as a device that is operated for providing the pre-staged transactions defined by the user.
At 330, the biometric-based pre-stage transaction agent provides the biometric token when the user provides a pre-staged transaction for subsequent processing on a transaction terminal.
It is to be noted that the biometric token is only retained on the device that the user operates when supplying the pre-staged transaction to the server for staging, such that the device in possession of the biometric token is capable of supplying the biometric token for biometric authentication at the time that the user defines and provides the pre-staged transactions to the server.
In an embodiment, multiple independent executing instances of the biometric-based pre-stage transaction agent are processed in performing the method 300, such that the processing associated with 310-340 is performed by a first instance of the biometric-based pre-stage transaction agent on a first registration device and the processing associated with 350 is performed by a second instance of the biometric-based pre-stage transaction agent on a second device.
In an embodiment, the biometric-based pre-stage transaction agent performs all of the processing recited 310-351 on a single and same device.
