Imperceptible Technique to Secure Digital Audio Signals while Attaining Trade-Off among the Parameter of Magic Triangle

Abstract

Abstract: This paper outlines an audio encryption method that is used during audio compression. Security for the multimedia data is provided by encryption methods. Here, audio encryption is a method used to communicate secret information by subtly altering an audio stream. It is a technique that guarantees secure data transfer between parties that often interact online. Here, we offer a fresh method for dealing with issues raised by audio encryption's substitution mechanism. We employ an enhanced RSA encryption technique, which is incredibly difficult to crack, to encrypt messages in the first level of protection. The encrypted message bits are embedded into random LSB layers to boost robustness against purposeful assaults, in which the hackers constantly attempt to reveal the hidden message, as well as some inadvertent attacks, like noise addition. Here, GA operators are utilised to lessen distortion. The major goal of this work is to propose a good, effective way for hiding data from hackers and sending it to the target in a safer manner by maintaining randomization in message bit insertion into audio data.
