Systems and methods for encoding randomly distributed features in an object for use with an authentication label

摘要

A method and apparatus is disclosed which includes the steps of (a) determining randomly distributed features in an object, (b) compressing data representing the randomly distributed features, (c) encoding the compressed data with a signature, and (d) creating a label that includes the object and the encoded data. The step of compressing data includes determining a probability density function associated with the object, determining vectors associated with the randomly distributed attributes based, at least in part, on the probability density function, and encoding the vectors using an algorithmic coding algorithm. A label is provided which includes an authentication object which includes randomly distributed features, and encoded information associated with the authentication object. The information is encoded with a signature, and includes compressed data representing the randomly distributed features in the authentication object. The label itself is self-authenticated by comparing the compressed data in the encoded information, and the data representing the randomly distributed features obtained by analysing the authentication object.
