Outline of Final Research Achievements

We defined third person cannot obtain evidence of remote biometric authentication transaction as "receipt-freeness", if the third person could not collects intermediate information of biometric authentication process such as communicating data. Depending upon the discussion of "receipt-freeness", we also defined no user could obtain the evidence such that coercer who constrained the user to execute biometric authentication is convinced as "coercion-resistance."
From the above definition, we investigated whether "receipt-freeness" and "coercion-resistance" are satisfied or not in conventional remote biometric authentication protocols. As a result, most of them did not satisfy. We read the papers of the results at domestic conference (4 papers) and international conference (2 regular papers and 2 invited lectures) of information security.
