Audio Encryption Using Fragile Watermarking

Mobile DRM-Enabled Multimedia Platform for Peer-to-Peer Applications

“…The watermarks can also be used to scramble the audio content. [10] This method provides lightweight encryption combined with watermarking.…”

“…The first method utilizes hash chains [11] and the second embeds the counter value in the watermark [10].…”

A teleassistance protocol based on joint watermarking–encryption evidence for identification of liabilities in case of litigation

“…• "Watermarking Followed by Encryption" (WFE) [8,9,17] where the issuer generates and embeds the recipient fingerprint within a copy before encrypting it. Herein, the seller is considered as honest.…”

“…Nowadays, different protocols [8][9][10][11][12][13][14][15][16][17][18][19] combine them in order to benefit from the complementarity of these two mechanisms in terms of a priori/a posteriori protection, and consequently to provide a better security response. Most of them focus on the copyright protection in the framework of video on demand (VOD), where the objective is to identify the person (issuer or recipient) at the origin of an illegal distribution by mean of a watermark (a fingerprint).…”
