Abstract
A method and a system are provided for matching a fingerprint, for example, an audio fingerprint. In one example, the system receives, from a user device, a chapter and a query about the chapter. The chapter includes computer readable data generated from a waveform of an audio signal. The query is a request to receive data related to the chapter. The system generates, at a computer, a fingerprint of the chapter. The fingerprint includes at least a digital measure of certain properties of the waveform of the audio signal. The system generates, at a computer, a hash value of the fingerprint by applying a hash function to at least a portion of the fingerprint of the chapter. The hash value serves as an identifier for the fingerprint. The system looks up, in a database system, a matching hash value for the hash value of the fingerprint.
