VECTOR GENERATION DEVICE, VECTOR GENERATING METHOD, AND INTEGRATED CIRCUIT

摘要

Provided are a vector generation device for generating data (or vector) to furnish a basis for an authentication processing such as a biometric authentication, while protecting such information against a secondary exploitation as can be authenticated at a high speed by exploiting the resources of a server and as should be handled as the secret information represented by a biometric template, a vector generating method and an integrated circuit. A terminal (100) includes a receiving unit (101) for receiving a characteristic extraction vector as a first vector from the outside, a storage unit (102) for storing a biometric template vector as a second vector, a vector operation unit (103) for calculating a correlation factor between the first vector and the second vector thereby to generate a third vector identical in the correlation factor but different from the second vector, and a transmission unit (104) for transmitting the third vector to a server (10).
