Biometric chain of provenance


The present disclosure is directed towards methods and systems for ensuring integrity of biometric data for one or more transactions. A mobile biometric device may acquire biometric information of an individual. A ranging module of a transaction device may determine that a distance between the mobile biometric device and a physical location of a first transaction with the individual is within a predefined value. The transaction device may link, responsive to the determination, the acquired biometric information to the first transaction if the biometric information is acquired within a specific time limit from the distance determination. The transaction device may link the acquired biometric information to a universal biometric record of the individual. A biometric integrity engine may compare information from the first transaction and a second transaction for inconsistency or fraud.

FIELD OF THE DISCLOSURE

The present disclosure relates to identity verification technologies, and more specifically to systems and methods directed to providing or ensuring a biometric chain of provenance.

BACKGROUND

The potential for fraud in financial transactions has increased significantly due to the increasing diversity in the means for transactions to be performed. For example, it is often challenging to ensure that biometrics acquired by a biometrics device are really those of an individual at the biometrics device. Moreover, in certain contexts, it may be necessary or more acceptable to acquire biometric of a moving individual without constraining the individual\'s advance or movements. However, conventional systems are typically not very robust against fraud and/or mistake when biometric acquisition is decoupled from traditional access control systems, or when individuals whose biometrics are being acquired are not rigidly constrained for the biometric acquisition process. Some ability to track an individual across one or more transactions may be a way to reduce fraudulent activity.

SUMMARY

The present disclosure describes methods and systems for tracking the provenance of an individual between disparate transactions that they perform, be they logical and/or physical access transactions. The present methods and systems may use acquisition and optional matching of potentially disparate biometrics at each point of transaction, and may provide means to ensure the provenance of each step within each transaction and/or between each transaction.

In some aspects, we leverage on one or more of the following to ensure integrity of acquired biometrics linked to one or more transactions: 1) the ability to track a particular individual to a transaction, and 2) the ability to track one transaction to a second transaction. In this way, the activity of a single individual can be tracked from one transaction to the next. This Biometric Chain of Provenance (BCP) can then be audited and verified, for example, not just between two transactions, but between many transactions that the individual performs. Every transaction, be it buying a coffee or buying a house or setting up a bank account, is therefore an opportunity for the integrity of the biometric chain of provenance to be validated. Any inconsistencies in the BCP computed either in real-time while a transaction is performed, or after-the-fact indicates that fraudulent activity is occurring (or potentially occurring) or has occurred (or potentially occurred). Due to the BCP, there is a substantial audit-trail and therefore we may: a) detect fraud based on the detection of anomalies in the audit-trail, b) identify the fraudster based on information contained in the audit-trail, and c) deter fraudulent activity since fraudsters know that such a biometric-based audit trail is known to exist.

As mentioned above, the ability to track a particular individual to a transaction can be a critical element in the process. Biometrics is the field of measurement of human characteristics, and the acquisition and optional matching of biometric data can be a component in such a process. However, it may be important that the provenance of the biometric information itself is ensured step by step between the individual, a device (static or mobile) that collects the biometric data, any point of sale (POS) terminal that communicates to said device, and the rest of the transactional system, for example in everyday environments, such as a busy check-out line with multiple people, or in a mobile unattended environment. The present disclosure describes embodiments of such methods in detail.

It is also recognized that the device platforms on which transactions are performed are becoming more disparate, as are the locations where they are performed. Devices and applications may therefore contain only certain biometrics such as iris, face or voice due to cost or availability constraints. The iris biometric in particular can be a powerful biometric for tracking transactions due to its standardization and its accuracy. If there is a need to search through millions of records to associate transactions just based on a biometric, then the iris biometric may be best-placed to do so compared to face and voice and many other biometrics. This can be most significant at the beginning of the BCP when a customer presents themselves to open up a new account, for example. A verification step in the BCP may check whether the customer should be linked to prior BCP activity (e.g., is the customer attempting to assume multiple identities). This can be performed reliably and quickly with the iris biometric. However, as discussed earlier, the platforms on which transactions are performed are becoming more disparate and non-iris biometrics may be used. The present disclosure describes in detail embodiments of methods for maintaining the Biometric Chain of Provenance even when disparate biometrics are used.

In one aspect, the present disclosure is directed to a method for ensuring integrity of biometric data linked to one or more transactions. A mobile biometric device may acquire biometric information of an individual. A ranging device may determine that a distance between the mobile biometric device and a physical location of a transaction with the individual is within a predefined value. The ranging device or a transaction device may link, responsive to the determination, the acquired biometric information to the transaction if the biometric information is acquired within a specific time limit from the distance determination.

In some embodiments, the ranging device or transaction device may compute the specific time limit based on an amount or rate of change in the location of the mobile biometric device. The ranging device may determine the distance between the mobile biometric device and the physical location via a global positioning system. The ranging device may determine the distance between the mobile biometric device and the physical location using a short-range location system, using one or more of a: radio-frequency, laser, infra-red and audio ranging process. In some embodiments, the biometric device may transmit the acquired biometric information to a biometric matching device located at or connected to the physical location. The biometric device may transmit the acquired biometric information to a transaction device located at or connected to the physical location if the distance is determined to be within the predefined value.

In some embodiments, the ranging device or transaction device may link the acquired biometric information to the transaction if the acquired biometric information is received by a transaction device associated with the physical location within a predetermined time period of initiating the transaction. The ranging device or transaction device may link the acquired biometric information to the transaction if the distance between the physical location and the biometric device at the time the transaction is initiated is within a specified value. The transaction device at the physical location may allow or deny the transaction at the physical location based on biometric verification using the acquired biometric information. The transaction device may allow or deny the transaction based on biometric verification using the acquired biometric information, the transaction comprising one of: a point-of-sale transaction, a point-of-service transaction, and an access control transaction.

In some embodiments, the ranging device determines the distance between the mobile biometric device and a physical location based on strength of a signal received at one of: the physical location and the mobile biometric device, and transmitted by the other. The biometric device and/or the transaction device may identify the individual based on the acquired biometrics, and linking the transaction at the physical location with the individual. The biometric device and/or the transaction device may retrieve an identifier of the individual based on the acquired biometrics, and linking the transaction at the physical location with the identifier. The transaction device may link the transaction with another transaction linked to the individual, and comparing information of both transactions for inconsistency or fraud. The transaction device may link the transaction to a universal biometric record of the individual. The universal biometric record may include biometric information of a first type that matches the acquired biometric information.

In another aspect, the disclosure is directed to a method for ensuring integrity of biometric data linked to one or more transactions. A biometric device may acquire biometric information of an individual. A transaction device may link the acquired biometric information to a first transaction of the individual and a universal biometric record of the individual. The universal biometric record may include biometric information of a first type that matches the acquired biometric information, and may include biometric information of a second type. The transaction device or a biometric integrity engine may identify, via the universal biometric record, a second transaction. The second transaction may be linked to acquired biometric information that matches the biometric information of the second type. The transaction device or biometric integrity engine may compare information from the first transaction and the second transaction for inconsistency or fraud.

In yet another aspect, the disclosure is directed to a method for ensuring integrity of biometric data linked to one or more transactions. A biometric device may acquire biometric information of an individual. A transaction device may link the acquired biometric information to a first transaction of the individual. The universal biometric record may include an identifier of the individual and/or biometric information of a first type that matches the acquired biometric information. The transaction device or a biometric integrity engine may identify a second transaction linked with the identifier of the individual. The transaction device or biometric integrity engine may compare information from the first transaction and the second transaction for inconsistency or fraud.

In still another aspect, the disclosure is directed to a system for ensuring integrity of biometric data linked to one or more transactions. The system may include a mobile biometric device acquiring biometric information of an individual. A ranging device may determine that a distance between the mobile biometric device and a physical location of a transaction with the individual is within a predefined value. The ranging device or a transaction device of the physical location may link, responsive to the determination, the acquired biometric information to the transaction if the biometric information is acquired within a specific time limit from the distance determination.

In some embodiments, the system includes a database comprising a universal biometric record of the individual, for linking to the transaction. The universal biometric record may include biometric information of a first type that matches the acquired biometric information, and biometric information of a second type. The ranging device may compute the specific time limit based on an amount or rate of change in the location of the mobile biometric device. In certain embodiments, the system includes a mirror module at the physical location. The mirror module may be oriented to allow the acquisition of the biometric data using a rear-facing camera on the biometric device. In some embodiments, the system includes a second biometric device for acquiring imagery of the individual at substantially the same time as the acquisition of the biometric data.
