Today, steganography is known as an effective way to convey secret data. A wide range of
techniques has been developed in this context, each seeking to improve certain problems of …

This work presents a steganographic scheme based on Laplacian-of-Gaussian (LoG) edge
detection and least significant bit (LSB) substitution. The cover image is first divided into …

Data hiding is the art of hiding data for various purposes such as; to maintain private data,
secure confidential data and so on. There are lots of techniques used for data hiding and the …

With the massive growth in internet applications, there is a continuous need of efficient
steganography techniques for the purpose of secret data communication and for the …

Image-based steganography is an essential procedure with several practical applications
related to information security, user authentication, copyright protection, etc. However, most …

An effective spatial domain steganographic scheme is proposed in this paper. Particle
swarm optimisation (PSO) can be used to identify the most efficient pixel position in the …

With the intrusion of internet into the lives of every household and terabytes of data being
transmitted over the internet on daily basis, the protection of content being transmitted over …

Several problems arise among the existing LSB-based image steganographic schemes due
to distortion in a stegoimage and limited payload capacity. Thus, a proposed scheme has …

In this paper we have proposed a new technique of hiding a message on least significant bit
of a cover image using different progressions. We have also compared the cover image and …
