A new approach algebraic to speech signal encryption using watermarking

Abstract

The watermark is an effective tool for encoding signals of all kinds, whether in the field of sound or image. The watermark can be a way to identify and indicate the owner of the content. There are several types of watermarks also vary in durability and use to counter attacks and types of threats. Regarding the watermark used in our research, it is a text sentence as a gray square image with dimensions (128*128*3) converted into a binary matrix. We can also change the watermark with another larger or different one according to our needs, in order to use it later with a speech signal.
