Efficient prevention of fraud
First Claim
1. A method for selective identification of biometric data for efficient compression, the method comprising:
- (a) determining, by an evaluation module operating on a biometric device, if a set of biometric data acquired from a subject satisfies a quality threshold indicating sufficiency of quality for subsequent automatic or manual biometric recognition, while satisfying a set of predefined criteria that includes criteria for achieving efficient compression of a corresponding type of biometric data, which includes estimating an expected amount of compression artifacts that data compression would introduce to the set of biometric data, accessing a table that relates amounts of compression artifacts introduced in biometric data to predetermined threshold levels for biometric recognition, and comparing the expected amount with a corresponding threshold level indicated by the table for the biometric recognition, the determination including the estimation, the access and the comparison performed prior to performing data compression on the set of acquired biometric data; and
(b) classifying, based on the determination, whether to retain the set of acquired biometric data for subsequent data compression.

Abstract
This disclosure is directed to methods and systems for managing difficulty of use and security for a transaction. A transaction manager operating on a computing device may determining a range of possible steps for a transaction comprising security measures available for the transaction. The transaction manager may identify a threshold for a security metric to be exceeded for authorizing the transaction, the security metric to be determined based on performance of steps selected for the transaction. The transaction manager may select for the transaction at least one step from the range of possible steps, based on optimizing between (i) a difficulty of use quotient of the transaction from subjecting a user to the at least one step, and (ii) the security metric relative to the determined threshold.

11. A system for selective identification of biometric data for efficient compression, the system comprising:
-
a sensor, configured to acquire a set of biometric data; and an evaluation module comprising circuitry configured to; determine, prior to performing data compression on the set of biometric data acquired from a subject, if the acquired set of biometric data satisfies a quality threshold indicating sufficiency of quality for subsequent automatic or manual biometric recognition, while satisfying a set of predefined criteria that includes criteria for achieving efficient compression of a corresponding type of biometric data, which includes estimating an expected amount of compression artifacts that data compression would introduce to the set of biometric data, accessing a table that relates amounts of compression artifacts introduced in biometric data to predetermined threshold levels for biometric recognition, and comparing the expected amount with a corresponding threshold level indicated by the table for the biometric recognition, the determination including the estimation, the access and the comparison performed prior to performing data compression on the set of acquired biometric data; and classify, based on the determination, whether to retain the acquired set of biometric data for subsequent data compression. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
