Abstract

Key-dependent sampling of a biometric characteristic is performed at a client, to thereby generate key-dependent biometric data samples. The key-dependent biometric data samples are then transmitted from the client to a server. By sampling the biometric characteristic at the client in a key-dependent manner, the key-dependent biometric data samples may be transmitted from the client to the server without the need for additional encryption and / or a signature. A key is preferably transmitted from the server to the client. The key is then used to perform the key-dependent sampling of the biometric characteristic at the client. The key-dependent sampling may be performed by sampling the biometric characteristic at a sampling frequency that is a function of the key. Alternatively, the key can be applied to the sampled biometric data, to thereby generate the key-dependent biometric data samples that are a function of the key. The key is preferably used to perform nonlinear key-dependent sampling of the biometric characteristic at the client, for example by using the key to determine the sampling frequency and also using the key to apply a nonlinear function to the sampled biometric data. Further encryption of the biometric data and / or the use of a signature with the biometric data need not be performed.

Description

field of invention [0001] The present invention relates to a system, method and computer program product for identifying and / or authenticating an individual, in particular, to a system, method and computer program product for identifying and / or authenticating an individual with biometric data. Background of the invention [0002] Currently, biometric information is used as a technique for identifying and / or authenticating an individual. As is well known to those skilled in the art, biometric information is one or more behavioral and / or physiological characteristics of an individual. Biometric identification and / or verification uses a data processing system to automate the identification and / or verification of an individual's identity through computerized assessment of biometric characteristics. In biometric verification, the biometric information of a known individual is verified. In biometric identification, an individual's biometric information is compared with the biomet...
