چکیده
To develop and check the Steganography based information’s by using Matlab this proposal investigates the detection of information hidden in digital media by both the least significant bit (LSB) matching and replacement scheme. Which can completely recover the original images without any distortion from the secret images by utilizing the parity features of the original images and defining two embedding pairs are used embeds hidden message via LSB matching and replacing the LSB of the cover image with the MSB of the message image will help us to form a stego image which would contain the message. This message can be retrieved only by that receiver who knows that it is a stego image sent by the sender. The proposed method always has lower distortion for various levels of abstractions. Experimental results disclose that the proposed method not only provides better performance and size reductions than those of OPAP and DE, but also is secure under the detection of some well-known steganalysis techniques tested here.

Optimizing image steganography by combining the GA and ICA
In this study, a novel approach which uses combination of steganography and cryptography for hiding information into digital images as host media is proposed. In the process, secret data is first encrypted using the mono-alphabetic substitution cipher method and then the encrypted secret data is embedded inside an image using an algorithm which combines the random patterns based on Space Fillin...

This paper devotes itself to the study of secret message delivery using cover image and introduces a novel steganographic technique based on genetic algorithm to find a near-optimum structure for the pair-wise least-significant-bit (LSB) matching scheme. A survey of the related literatures shows that the LSB matching method developed by Mielikainen, employs a binary function to reduce the numbe...

In this paper, a faster method for embedding cryptographic information in the image ispresented by expressing the concept of latent prints (Steganography). Data is encrypted bytwo methods before embedding to increase reliability. Then they are embedded into the imageby a button, a method has been expressed to reduce potential noise impact on the wayinformation is encoded.
متن کاملTailored Image District Processing Precision Andwritten Appreciation
The project proposes the data hiding technique using adaptive pixel pair matching (PPM) and LSB Replacement for secret data communication. The basic idea in LSB is the direct replacement of LSBs of pixel bits of the cover image with the secret message bits. The basic idea of PPM is to use the values of pixel pair as a reference coordinate and search a coordinate in the neighborhood set of this ...
متن کاملLsb Steganography with Improved Embedding Efficiency and Undetectability
In this paper, we propose a new method of non-adaptive LSB steganography in still images to improve the embedding efficiency from 2 to 8/3 random bits per one embedding change even for the embedding rate of 1 bit per pixel. The method takes 2-bits of the secret message at a time and compares them to the LSBs of the two chosen pixel values for embedding, it always assumes a single mismatch betwe...
