METHOD OF ZERO KNOWLEDGE PROCESSING ON BIOMETRIC DATA IN DISCRETISED VECTOR REPRESENTATION

摘要

The present invention provides a method comprising: encoding of a biometric vector-stream, as comprises a sequence of biometric vector-frames, during an authentication interaction between a client and a server sub-system, wherein encoding of any particular biometric vector-frame is different from any other biometric vector-frame in vector-stream of interest; secure transmission of such an encoded biometric vector-stream as originating from a particular user of interest operating the client to the server; and then decoding at the server of the encoded biometric vector-stream as received from the client; further comprising limitation in capability of server to undertake such decoding by subject to correct demonstration of private PKC credential corresponding to public credential stipulated by the user during the authentication interaction.
