Abstract: A technique for inverted client side fingerprinting and matching provides the benefits of disposable fingerprinting to identify multiple content streams from multiple clients without overloading a fingerprinting system. Rather than tasking a fingerprinting system with the generation and comparison of all fingerprints, the technique distributes some fingerprinting tasks to the clients receiving the content streams. As a result, the fingerprinting system is not bottlenecked by fingerprinting tasks. In one embodiment, the fingerprinting system can provide additional services to the clients.

Abstract: Systems and methods are provided herein relating to audio matching. Adaptive weighting of popular reference content can be used to more efficiently allocate space in a weighted reference index used to match audio signals. An audio reference index can be maintained that contains a set of audio references wherein each audio reference in the set of audio references is associated with a score. A weighted reference index can be generated based on the audio reference index and the score associated with each audio reference wherein respective audio references are up-weighted or up-scored based at least in part of user popularity. The benefits in using adaptive weighting of popular reference content can improve the accuracy of an audio matching system.

Abstract: Systems and methods described herein can assign a confidence score to a match of unstructured descriptive information with structured reference information in a reference database. The systems and methods can take into account the structured nature of the reference information in assigning the score, thereby facilitating increased confidence in the match, and consequently, facilitating improved database organization and content identification.

Abstract: An audio recognition service recognizes an audio sample across multiple content types. At least a partial set of results generated by the service are returned to a client while the audio sample is still being recorded and/or transmitted. The client additionally displays the results in real-time or near real-time to the user. The audio sample can be sent over a first HTTP connection and the results can be returned over a second HTTP connection. The audio recognition service further processes check-in selections received from the client for content items indicated by the results. Responsive to receiving the check-in selections, the service determines whether a user is eligible for a reward. If the user is eligible, the service provides the reward.

Abstract: Systems and methods for facilitating higher confidence matches are provided. In one embodiment, a system includes a memory that stores computer executable components, and a microprocessor that executes the computer executable components stored in the memory. The components can include a metadata matching component that determines a metadata match level between metadata of a plurality of files, and a thresholding component. The thresholding component may compare a metadata threshold with the metadata match level and output a signal configured to cause a decrease in a melody matching strength threshold from a first value to a second value based at least on the metadata match level being greater than the metadata threshold.

Abstract: The present disclosure includes, among other things, systems, methods and program products for selecting subsequences (shingles or tuples) generated from sequences of tokens.
