Title:
SECURE RE-ENROLLMENT OF BIOMETRIC TEMPLATES USING DISTRIBUTED SECURE COMPUTATION AND SECRET SHARING
Document Type and Number:
Japanese Patent JP2019185781
Kind Code:
A
Abstract:
To perform re-enrollment of a living body using distributed secure secret sharing in a networked authentication system.SOLUTION: A computing device includes a shares generation unit configured to generate a plurality of secret shares of biometric information of a user; a storage interface to store each of the plurality of secret shares into a corresponding storage node; and a computation engine to generate helper data to authenticate a user according to the biometric information of the user and to perform re-enrollment of the biometric information. The computing device outputs a plurality of messages in order to instruct each of the plurality of storage nodes to generate respective shares of new helper data in order to perform re-enrollment of the biometric information, receives the respective share of the new helper data from two or more storage nodes out of the plurality of storage nodes for next authentication of the user, and determines new helper data.SELECTED DRAWING: Figure 4
