Abstract :
A group signature scheme allowed a group member to sign messages anonymously on behalf of the group. Fingerprinting schemes enable a merchant to identify the buyer of an illegally distributed digital good by providing each buyer with a slightly different version. An anonymous fingerprinting scheme allows the buyer to purchase goods without revealing her identity to the merchant. We propose an efficient anonymous fingerprinting scheme that uses group signature schemes.
