Abstract:
A content fingerprint based recognition system employs local caching of portions of a fingerprint database to manage network services for identifying which programs a user's mobile device is exposed to and the timing of events within the program. The system enables background recognition and synchronization of network services in a way that consumes less device power and bandwidth.
