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

چکیده
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.

Improve Security & Quality of Stego Image Using Proposed LSB Method
Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information.In this paper proposed method focus on improving quality of stego image by increasing value of PSNR and SNR with less number of LSB changed compare to simple LSB method result in better security. This paper also compares results of proposed method with simple LSB.

In this paper, proposed an advance approach for dynamic data protection using LSB and hybrid approach. Steganography is the art of communicating a message by embedding it into multimedia data. The proposed method for replacing one or two or three LSB of each pixel in video frame and apply Advance encryption standard (AES). It becomes very difficult for intruder to guess that an image is hidden ...
