An implementation is described herein facilitates certification of goods and/or identifications of the source of such goods. At least one implementation, described herein, embeds a watermark into a relatively small amount of data in a deterministic manner. At least one implementation, described herein, generates an authentication transformation matrix based, at least in part, upon an authentication watermark and a pre-defined humanly perceptible authentication pattern (e.g., image, audio). With this implementation, it obtains subject goods that may have the authentication watermark embedded therein. It generates a humanly perceptible resultant pattern (e.g., image, audio) based, at least in part, upon the watermark detected in subject goods and the transformation matrix. If the detected watermark is the authentication watermark, then the resultant pattern and the pre-defined authentication pattern will match (or nearly so). At least one implementation, described herein, hides a secret key around the periphery of watermarked goods. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
An architecture facilitating authentication of goods, the architecture comprising:
A processor-readable medium having processor-executable instructions that, when executed by a processor, performs a method comprising:
A method comprising:
A system comprising:
A processor-readable medium having processor-executable instructions that, when executed by a processor, performs a method comprising:
A method for authenticating goods, the method comprising:
A goods authentication system, comprising a goods authenticator configured to facilitate a determination regarding whether subject goods are genuine based at least in part upon a presentation of a humanly perceptible pattern based upon a combination of a pre-defined transformation matrix and the subject goods, wherein the predefined transformation matrix is based, at least in part, upon a pre-defined humanly perceptible authentication pattern and a watermark of marked original goods, wherein a function of the matrix and the marked goods produces a humanly perceptible pattern that is significantly similar to the authentication pattern.
