Claim One:
1. A method implemented by computer means of searching content, at least one extract common to a first file and to a second file, in the form of binary data, being searched for, wherein the method comprises: a prior preparation of the first file at least, comprising the following steps: a) segmenting the first file into a succession of data packets, of chosen size, and identifying addresses of packets in said file, b) associating with the address of each packet a digital signature defining a fuzzy logic state from among at least three states: “true”, “false” and “undetermined”, said signature resulting from a combinatorial calculation on data emanating from said file, and the search for common extract, itself, comprising the following steps: c) comparing the fuzzy logic states associated with each packet address of the first file, with fuzzy logic states determined on the basis of data emanating from the second file, d) eliminating from said search for common extract, pairs of respective addresses of the first and second files whose respective logic states are “true” and “false” or “false” and “true”, and preserving the other pairs of addresses identifying data packets liable to comprise said common extract.
