TIC-TAC Based Live Acoustic Watermarking With Improved Forgery Detection Performances

Audio recording authentication becomes a necessity as the evolution of technology allowed the manufacturing of small and performant recording devices. The difficulty of editing audio recordings has decreased significantly, given the development of the audio editing software. The paper describes an improved version of a recently proposed live watermarking system based on the TIC-TAC signal. The version presented in this paper eliminates some detection flaws of the original version, studies the effect of the propagation of the original live watermark signal through various acoustic environments, and proposes an improved version that is less affected by those effects.
