Summary:A method and system for fingerprinting a content item is described, the content item including a set of content item elements E, providing information uniquely associated with a single user including a string of bits S0, parsing S0 into a plurality of substrings which are functions of S0, providing a matrix of content item replacement elements, each row of which includes, for each member of E, an array of content item replacement elements for Ei, uniquely associating each substring of S0 so that for every substring there exists a corresponding element of E, for every substring, replacing at least one instance of the corresponding element E in the content item with one substitute matrix element for the corresponding substring, and outputting a replacement content item including the result of the replacing, the substitute matrix elements being chosen according to at least one similarity criterion.
