Abstract
A biological information authentication device is provided with a biological information memory means, a user group information confirmation means, a biological information registering means and an authentication unit. The user group information is the information representing a trust relationship among a plurality of users; the biological information memory unit associates each biological information extracted from a plurality of users with the user group information and stores them. The user group information confirmation unit receives a determination as to whether or not a trust relationship exists among a plurality of users from whom the biological information is extracted and confirms the relationship between users. The biological information registering unit matches the user group information and stores each biological information extracted from each user in association with the biological information memory means.
