VECTOR GENERATION DEVICE, VECTOR GENERATING METHOD, AND INTEGRATED CIRCUIT

摘要

An object of the invention is to provide a vector generation apparatus, a vector generation method, and an integrated circuit for generating data (vector) as a basis for authentication processing such as biometric authentication while protecting information that can be authenticated at high speed using the resources of a server and should be handled as secrete information typified by a biometric template against secondary use. A terminal 100 includes a reception section 101 for receiving a feature extraction vector as a first vector from the outside; a storage section 102 for storing a biometric template vector as a second vector; a vector computation section 103 for calculating a correlation efficient between the first vector and the second vector and generating a third vector different from the second vector, with the correlation coefficient matching the correlation efficient; and a transmission section 104 for transmitting the third vector to a server 10.
