A Modified Lsb Image Steganography Method Using Msb-Based Pixel Filtering Algorithm

Abstract

Data is one of the most particularly substantial ways now and has to fight correctly with the rising concern of cybersecurity. Furthermore, every time, info is lurked and changed from the online when directed. Thereupon, to strengthen safety when broadcast, aside from the two ways accessible, one is cryptography and second one is steganography. In the cryptography system, info is programmed to cryptogram text by non-public key, yet the data’s corporeality is apparent to others, regardless of how impenetrable they are. In addition, steganography hides private data in a common confidential file to escape eye recognition. This study offered a unique information concealing approach leveraging LSB image steganography, in which concealed data employs just the user-selected picture elements. On the contrary, image element info is employed to strainer the complete picture to find the seeker image element, and a stoner-defined word is utilized to protect the LSB steganography. To improved safety, the XOR mathematical scheme is utilized to incorporate confidential information, before performing steganography, the AES system encodes the confidential text. During the case study, various quality measure metrics values are multiplied to determine the quality of the succeeding stego image. The stego image offers developing PSNR and lower MSE value as related to other investigated styles, which suggests the inflexibility of the recommended scheme.
