Space Efficient and Integrity-ensured Secret Sharing Schemes for Multimedia Secrecy without Recursion

Abstract

Multimedia is content that uses a combination of different content forms. To share multimedia among multiple users secretly becomes a tough challenge because the amount of transmitted or involved data might be large. To ensure efficiency and security for multimedia secret sharing, we propose two secret sharing schemes without recursion in this paper, where the second scheme can control the security of produced shares. The proposed schemes ensure both security and efficiency and further provide a mechanism to check the integrity of the recovered secret.
