  • Homomorphic Encryption For Secure Watermarking
    Publication number: 20080212780
    Abstract: A method and a system for embedding a watermark in a media signal x are disclosed. The method comprises providing an at least partially encrypted media signal cx of said media signal x, wherein encryption is performed using a first encryption key k1; providing an at least partially encrypted watermark signal cw, wherein encryption is performed using a second encryption key k2; combining the at least partially encrypted media signal cx and the at least partially encrypted watermark signal cw in a combiner to obtain an encrypted combined media signal cy; and obtaining a decrypted watermarked media signal y by decrypting said encrypted combined media signal cy using a third decryption key k3. The present invention provides a framework for secure watermark embedding within untrusted devices.
