ABSTRACT:
Methods and systems for watermark embedding in a multimedia system-on-chip are disclosed and may comprise decrypting an encrypted and signed watermarking signal using a security processor integrated within the system-on-chip and embedding a watermark into a multimedia signal utilizing the decrypted watermarking signal, which may comprise an embedding key, a message to be embedded, and embedding parameters. The encrypted and signed watermarking signal may be received from an external memory via a host CPU within the system-on-chip or a secure server. The decrypted watermarking signal may be verified utilizing a signature, a public key and a random number generated locally. The verified watermarking signal may be stored on a non-volatile memory within the system-on-chip, or re-encrypted and re-signed before storing on a non-volatile memory that is external to the system-on-chip. The watermarking signal may be retrieved from the external non-volatile memory and re-decrypted and re-verified within the system-on-chip.
