Steganography is a method of secret communication that hides the existence of hidden message. The hidden message can be text, image, audio, video, etc. The innocent files can be a cover image after inserting the message into the cover image using stego-key, it is reffered to as stego-image. Steganography becomes more important due to the exponential growth and secret communication of potential ...

Now-a-days a fast growth of internet in the present world, social networking websites like Twitter& Facebook are being increasingly used by individuals of all over the world to share their life activities and events via images. But this vastly popular observable fact of image sharing on internet is exposed to a lot of risks. At present, these social networking websites are not bounded by string...

Steganography is the science of secure communication which has received much attention from the scientific community recently. The four main objectives of steganography are: Indefectibility, Security, embedding payload, and Robustness. However, steganography can protect data by hiding it in a cover object but using it alone may not guarantee total security. Thus, the use of encryption in stegan...

Steganography is one of the cryptography techniques where secret information can be hidden through multimedia files such as images and videos. offer a way exchanging encrypted in an untypical mechanism communicating parties only interpret message. The literature has shown great interest least significant bit (LSB) technique which aims at embedding message bits into most insignificant image pixe...

-Steganography is a term used for covered writing. Steganography can be applied on different file formats, such as audio, video, text, image etc. In image steganography, data in the form of image is hidden under some image by using transformations such as ztransformation, integer wavelet transformation, DWT etc and then sent to the destination. At the destination, the data is extracted from the...

Steganography, or communication through covert channels, is desirable when the mere existence of an encrypted message might cause suspicion or provide useful information to eavesdroppers. Text is effective for steganography due to its ubiquity. However, text communication channels do not necessarily provide sufficient redundancy for covert communication. We propose a novel steganographic embedd...

Text-cover of contemporary linguistic steganography approaches has numerous flaws such as incorrect syntax, lexicon, rhetoric, and grammar. Additionally, the content of text-cover is often meaningless and semantically incoherent. Such detectable noise (flaws) by both human and machine examinations can easily raise suspicion. These deficiencies render contemporary approaches highly vulnerable. U...

The staggering growth in communication technology and usage of public domain channels (i.e. Internet) has greatly facilitated transfer of data. However, such open communication channels have greater vulnerability to security threats causing unauthorized information access. Traditionally, encryption is used to realize the communication security. However, important information is not protected on...

Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. The motivation for this work includes provision of protection of information during transmission without any detection of information. We also propose a new technique namely „A New Steganography Technique Based on Difference Scheme of RGB Channels and Text Using Histogram ...
