An apparatus for content item signature matching comprises a database (103) which has signatures for a plurality of content items. A likelihood processor (105) determines a match likelihood indication for the content items where the match likelihood indication is indicative of a likelihood of a match between the content item and an unknown signature. An interface (111) receives a query signature associated with a content item and in response a search processor (113) searches the database (103) for a matching signature to the query signature. The search processor (113) is operable to search the database in response to the match likelihood indication of the plurality of content items. In particular the database (103) may be ordered in order of decreasing probability of a match and the search processor (113) may search the database in this order. Hence, the probability of an early match is increased and the average search time is reduced.

A digital signature is obtained by digitising a set of data points obtained by scanning a coherent beam over a paper, cardboard or other article, and measuring the scatter. A thumbnail digital signature is also determined by digitising an amplitude spectrum of a Fourier transform of the set of data points. A database of digital signatures and their thumbnails can thus be built up. The authenticity of an article can later be verified by re-scanning the article to determine its digital signature and thumbnail, and then searching the database for a match. Searching is done on the basis of the Fourier transform thumbnail to improve search speed. Speed is improved, since, in a pseudo-random bit sequence, any bit shift only affects the phase spectrum, and not the amplitude spectrum of a Fourier transform represented in polar coordinates. The amplitude spectrum stored in the thumbnail can therefore be matched without any knowledge of the unknown bit shift caused by registry errors between the original scan and the re-scan.
