Abstract

The present invention provides a method for generating fingerprints (1) of information signals (2), and in particular of video signals, those fingerprints being robust with respect to the frame rate of the information signal. Embodiments achieve this robustness by computing a sequence (3) of sub-fingerprints (30) from the sequence of frames of the source information signal, the sequence of sub- fingerprints having a predetermined rate independent of the frame rate of the source, and each sub- fingerprint being derived from and dependent upon a data content of at least one frame of the information signal. The sub- fingerprints at the predetermined rate are then concatenated to form the fingerprint (1) of the source signal.
