ARRANGEMENT FOR COMPARING CONTENT IDENTIFIERS OF FILES
First Claim
1. An arrangement (1) comprising a comparator (11) for comparing a content identifier of a file with a content identifier of a further file, which content identifier is defined by at least one parameter, the arrangement (1) further comprising a selector (12) for selecting, from a group of at least two content identifiers of the file, in dependence of values of the parameters of the group of content identifiers, a sub-group of at least one content identifier of the file for said comparing.

Abstract
Arrangements (1) comprising comparators (11) for comparing content identifiers with each other, such as audio/video fingerprints, unique identifiers, hash algorithms, cyclic redundancy checks, titles, names, durations, sizes, album names and artist names of files such as audio/video/data files, are provided with selectors (12) for selecting, 5 from groups of content identifiers, in dependence of values of parameters of the content identifiers, sub-groups of content identifiers, to increase flexibilities. Calculators (13) calculate functions of the values of the parameters and further comparators (14) compare the functions with thresholds. Content identifiers may be defined by cost and accuracy parameters. Then, calculators (13) calculate first functions of the values of the cost 10 parameters and calculate second functions of the values of the accuracy parameters and further comparators (14) compare the first functions with first thresholds and compare the second functions with second thresholds.
