AUTHENTICATION AND SELF-SYNCHRONISATION OF AUDIO SIGNAL BY WATERMARKING USING EMPIRICAL MODE DECCOMPOSITION

Digital multimedia data is transmitted for numerous real time and non real time applications. In this process undesired intruders may cause the duplication, copying, modification. At this point authentication becomes a zenith issue. To avoid further illegal redistribution and misuse of digital data numerous techniques have been put forth in past decades. The research paper brings to light, number of methods from past years in field of data secrecy. Empirical mode decomposition is a method that provides efficient and resilient transmission of audio signal. Implementation of synchronization sequence causes self-synchronization. This paper brings to notice of the analysts a technique for authentication of such signals based on numerous data evaluation parameters.
