Compensation of degradation, security, and capacity of LSB substitution methods by a new proposed hybrid n-LSB approach

This study proposes a new hybrid n-LSB (Least Significant Bit) substitution-based image steganography method in the spatial plane. The previously proposed substitution by authors of this paper is combined with Rivest-Shamir-Adleman (RSA), RC5, and Data Encryption Standard (DES) encryption algorithms to improve security steganography, which one requirements Lempel-Ziv-Welch (LZW), Arithmetic Deflate lossless compression increase secret message capacity. Also, embedding was done randomly using logistic map-based chaos generator more. classical approaches based on were implemented different messages cover images. When results examined, it has been seen that approach showed improvement all three criteria steganography. consists n-LSB, RSA, Deflate, map had best regarding capacity, security, imperceptibility.
