Rhode Island - MediaSec Technologies today announced that the
United States Patent and Trademark Office has issued and published
patent number 6,243,480 for MediaSec's watermark-based MediaSign®
technology.
This patent includes 51 claims covering the digital authentication with analog documents that is central to the Company's MediaSign products. It describes a fundamental approach to applying digital watermark or barcode for authenticating any document, no matter whether the document is represented in the digital or analog form. Based on the issued patent, MediaSign embeds a secure hash value of document's semantic or significant information into the document as a digital watermark. This authentication watermark is perceptually invisible and does not alter the meaning of the signed document. Moreover, it is present in the prints of the signed document and therefore can be verified by converting the prints to the digital form. MediaSign takes full advantage of digital watermark's presence in the analog forms of a watermarked document, and bridges the gap between digital and paper authentication.
