| Summary: | A watermarking technique for speech content and speaker authenticationscheme, which is based on using abstracts of speech features relevant tosemantic meaning and combined with an ID for the speaker is proposed inthis paper. The ID which represents the watermark for the speaker, isembedded using spread spectrum technique while the extracted abstracts ofspeech features are used to represent the watermark for the speech, embeddedin the original speech file using secret key. The abstracts speech feature isimplemented using B-spline curve interpolation. The paper provides abackground knowledge for the concept of speaker watermarking and contentfragilewatermarking based on digital speech data. Then, the suggestedfeature based authentication scheme is developed and the results from theevaluation are presented. Show that the suggested scheme is successful incombining speech and speaker watermark authentication. |
