Abstract

The present invention discloses a method for identifying mobile devices in a similar sound environment. Each of the at least two mobile devices captures an input sound and extracts a sound signature from the input sound. In addition, the mobile device extracts sound features from the input sound, and determines a reliability value based on the sound features. The reliability value may refer to a probability of a common sound class given the sound feature. A server receives from the mobile device a packet containing the sound signature and a reliability value. A similarity value between sound signatures from a pair of mobile devices is determined based on corresponding reliability values ​​from the pair of mobile devices. Specifically, the voice signature is weighted by the corresponding reliability value. The server identifies mobile devices in similar sound environments based on the similarity values.

Description

technical field [0001] The present invention generally relates to identifying mobile devices in similar sound environments. More specifically, the present invention relates to identifying mobile devices in similar sound environments based on input sounds of the mobile devices. Background technique [0002] Modern mobile communication systems provide a variety of services to mobile device users. Such systems often provide advertising and social networking services based on location information of mobile device users. Location information of a user's mobile device may allow service providers to infer the user's environment and provide more targeted advertising and social networking services to the user. Additionally, location information for mobile devices in nearby locations or similar types of locations may allow service providers to provide information about users located in similar environments. [0003] One of the conventional methods determines the location of the mob...
