Description 258-269
There are big challenges to handle the content authentication and tamper detection in speech watermarking techniques.
These challenges can be addressed using the detection of epoch locations, logistic mapping, verification of the tamper
locations, and the Min algorithm. Epoch events provide the variable length epoch intervals, and it has been used to find the
variable lengths of frame segments in this work. The logistic mapping provides strong security for original signals. They can
provide a robust and secure method that addresses copyright issues, illegal intentional, or unintentional modifications, and
tampered locations. In this paper, we have implemented an epoch event based speech watermarking technique for tamper
detection using the logistic map method. It has been observed that the simulation results demonstrated that the PRE value is
approximately more than 82% and the PESQ value lies between excellent and good. It means that there are no significant
differences between original and watermarked signals and we have obtained a highly imperceptible, robust, and secure
system. Moreover, the overall simulation results of the proposed method provide the better solution as well as more security
than existing methods.
