Abstract
Systems and methods are provided for recording and validating modifications to a secured container. Modifications to the secured container by trusted parties are logged. The log may be maintained in a secured memory of an IHS (Information Handling System) and may be periodically validated. Each logged modification specifies a timestamp of the modification and the digital watermark assigned to the trusted party making the modification. Upon completing modifications, the secured container is sealed by imprinting the first digital watermark and the first timestamp at locations in the secured container specified by a watermarking algorithm assigned to the trusted party making the modification. Additional modifications may be serially watermarked on the secured container according the watermarking algorithm of the trusted party making each modification. The secured container is unsealed by re-applying each of the watermarking algorithms in reverse order. The integrity of the secured container, and each modification, is thus validated.
