A study of different steganographic methods

Abstract

Audio Steganography is a technique used to transmit hidden records by means of editing an
audio signal in an imperceptible manner. it is a way that ensures secured records transfer
among parties generally in internet network [2]. here we gift a novel technique for resolving
the troubles related to the substitution method of audio steganography. inside the first degree
of protection, we use an progressed RSA encryption algorithm (RPrime RSA) to encrypt
message, which could be very complex to interrupt. Within the next level, the encrypted
message is to be encoded into audio statistics for this we use a more powerful GA (Genetic
set of rules) based totally Least huge Bit) algorithm. a good way to boom the robustness
against intentional attacks wherein the hackers constantly strive to reveal the hidden message
in addition to some unintended attacks together with noise addition, the encrypted message
bits are embedded into random LSB layers. right here in order to reduce distortion, GA
operators are used. The fundamental concept at the back of this paper is maintained
randomness in message bit insertion into audio statistics for hiding the records from hackers
and to provide a terrific, efficient technique for hiding the facts from hackers and dispatched
to the vacation spot in a safer manner [5].
