Abstract: Client devices periodically capture ambient audio waveforms, generate waveform fingerprints, and upload the fingerprints to a server for analysis. The server compares the waveforms to a database of stored waveform fingerprints, and upon finding a match, pushes content or other information to the client device. The fingerprints in the database may be uploaded by other users, and compared to the received client waveform fingerprint based on common location or other social factors. Thus a client's location may be enhanced if the location of users whose fingerprints match the client's is known. In particular embodiments, the server may instruct clients whose fingerprints partially match to capture waveform data at a particular time and duration for further analysis and increased match confidence.

Abstract: A dialog system is accessed by a remote user and is typically configured to receive a natural language query from the user and return a natural language answer to the user. Dialog systems can be copied without authorization or can become an out-of-date version. A dialog system with a signature, referred to herein as a “signed” dialog system, can indicate the signature without affecting usage by users who are unaware that the dialog system contains the signature. The signed dialog system can respond to input such that only the designer of the dialog system knows the signature is embedded in the dialog system. The response is a way to check the source or other characteristics of the dialog system. A designer of signed dialog systems can prove whether an unauthorized copy of the signed dialog system is used by a third party by using publically-available user interfaces.

Abstract: Positive identification of local inhabitants plays an important role in modern military, police and security operations. Since terrorists use all means to masquerade as local inhabitants, the identification of terrorist or hostile suspects becomes an increasingly complicated task. The instant software solution will assist military, police and security forces in the identification of suspects using Voice Print Recognition (VPR) technology. Our VPR software will compare and recognize, or match, specific voice samples with stored, digital voice models (voice prints) for the purpose of establishing or verifying identity. VPR software will support an operator's decision and situational awareness through the verification of a person's identity (for instance: remote access control), but more importantly will assist in the identification of suspect individuals (identifying suspects among a large group of captured individuals).

Abstract: A file-identifying fingerprint or marker is associated with a media/audio file after waveform values are extracted therefrom via certain data extraction and/or audio analysis routines. The extracted waveform values are statistically manipulated so as to render an array of statistical values for the analyzed media/audio file, which are then compiled to form the custom marker, and embedded with the metadata of the media/audio file thereby marking the media/audio file. The custom marker or fingerprint can be matched against a set of reference fingerprints (e.g., in a database) to determine the identity of the signal or the similarity between two signals. Because of the nature of the fingerprint extraction algorithm, it does not suffer from many of the problems that plague existing solutions, and as compared to such solutions it is fast, efficient, highly accurate, scalable, and robust.
