"In this paper, the authors propose a threshold digital signature scheme by using RSA cryptography to authenticate multimedia content. Multimedia authentication deals with genuineness of the structure and content of the multimedia such as text, image, audio, video etc. The proposed scheme uses an efficient key distribution scenario where, the private key of the group is distributed as unique shares among the group members. The shares are calculated and distributed based on the ID of the group members by using efficient Shamir's secret sharing scheme."
