发明名称 IDENTIFICATION OF INPUT FILES USING REFERENCE FILES ASSOCIATED WITH NODES OF A SPARSE BINARY TREE
摘要 <p>An input profile is generated from an input audio file using a measurable attribute that was also used to generate reference profiles from reference audio files. The input profile is then subjected to a process that was also used to generate a reference profiles tree, which is structured as a sparse binary tree, from the reference profiles. As a result of the process, information of reference profiles having similar characteristics as the input profile, with respect to the measurable attribute, are retrieved from resulting nodes of the reference profiles tree. The input profile is then compared with this subset of the reference profiles, representing potential matches, to determine that either it matches one of the reference profiles, or that it is a spoof, or that it does not match any of the reference profiles.</p>
