Blind source mobile device identification based on recorded call
The method used the combination of entropy and MFCCs from near-silent frames. EntropyMFCC features exhibit high performance against statistical moments of MFCCs. The traces of the source transmitting devices were identified from recorded call. The method can be implemented through other service providers, i.e. cellular, PSTN.
