Abstract
The present disclosure provides identification and continuous monitoring of content, such as broadcast content, in real time, using a hierarchical, distributed approach to content identification. Identification, synchronization and verification are provided. Identification may be performed by an identification server using a reference database of fingerprints. The same or another computing device may be used perform synchronization, such that at least some portion of each fingerprint generated by client devices that form a verification group are synchronized for verification. Verification used to determine whether a client device continues to receive the same content identified during identification compares at least a portion of each fingerprint generated by each client device of a verification group. If a mismatch occurs, identification may be repeated to identify the new content being received by a client device.
