ABSTRACT:
Our invention describes a method and a system for matching securely an unknown audio recording with known audio recordings. A plurality of known audio recordings, each known audio recording associated with an index to information uniquely identifying the known audio recording is stored on a server. An unknown audio recording cross-correlated securely with each of the plurality of known audio recordings to determine a best matching known audio recording, in which the unknown audio recording and the plurality of known audio recordings are encrypted with a public key. A best matching known audio recording is determined securely according to the cross-correlation. Next, the index of the best matching known audio recording is determined securely. Finally, the information associated with the index of the best matching known audio recording is provided securely to a user of the unknown recording.
