A secure server may be utilized to support watermark embedding in multimedia system-on-chips, by generating an encrypted and signed watermarking signal for use in each particular system-on-chip. The encrypted and signed watermarking signal is generated based on a unique per-chip ID associated with the particular system-on-chip. The watermarking signal may be signed by the secure server utilizing a random number generated in and/or provided by the particular system-on-chip. The watermarking signal may be encrypted by the secure server based on a secret encryption key associated with the particular system-on-chip. The secret encryption key may be determined based on the unique per-chip ID associated with the particular system-on-chip. The secure server may store information, received from various system-on-chips, for use during generation of watermarking signals.
