Performance Improvement of Threshold based Audio Steganography using Parallel Computation

Abstract

Abstract-Audio steganography is used to hide secret information inside audio signal for the secure and reliable transfer of information. Various steganography techniques have been proposed and implemented to ensure adequate security level. The existing techniques either focus on the payload or security, but none of them has ensured both security and payload at same time. Data Dependency in existing solution was reluctant for the execution of steganography mechanism serially. The audio data and secret data pre-processing were done and existing techniques were experimentally tested in Matlab that ensured the existence of problem in efficient execution. The efficient least significant bit steganography scheme removed the pipelining hazard and calculated Steganography parallel on distributed memory systems. This scheme ensures security, focuses on payload along with provisioning of efficient solution. The result depicts that it not only ensures adequate security level but also provides better and efficient solution.

Improvement of Steganography Technique: A Survey

“…The parallel mechanism also implemented into FPGA device with creating instruction sets [13] and creating AVX instruction for vectorization [14]. The parallel mechanism in steganography also proposed hiding messages into audio files by calculating histogram and inserting message in parallel processes [12]. The advantages of steganography using parallel mechanisms besides less processing time also eliminate dependency on serial processes [12].…”
