A Palette Based Approach for Invisible Digital Watermarking Using the Concept of Run-Length

TL;DR: A technique for hiding the data of images using palette based approach with the concept of run length has been proposed and both the image is initially quantized using the palette.
Abstract: In this paper, a technique for hiding the data of images using palette based approach with the concept of run length has been proposed. At the source, the image which is to be hidden (target image) is encoded within another image (cover image). Firstly, the cover image and the target image can be of any size which will be adjusted by our resize function thereby removing the size constraint. The final encrypted image (cover and target) image is sent over the network. This image is decoded at the receiver end. This approach is a palette based approach since both the image is initially quantized using the palette. The encoding of the target image at the sender end is done using the concept of run-length.

TL;DR: A new technique for hiding the data of images is proposed to hide an image file entirely with in another image file keeping two considerations in mind which are Size and Degree of Security.
Abstract: In this paper, a new technique for hiding the data of images has been proposed This method is invented to hide an image file entirely with in another image file keeping two considerations in mind which are Size and Degree of Security At the source, the image which is to be hidden (target image) is encoded at the end of another image (cover image) Double layer security of the hidden image can be achieved (over the untrusted network) by; firstly, the starting point of encoding the image data is depended on the size of the images and it is stored within the encoded image at the end of its header information as a cipher text; secondly, the target image is hidden behind the cover image by following our encrypted image hiding technique

TL;DR: A heuristic approach for Information hiding in the form of multimedia objects or text using Steganography is proposed keeping in mind two considerations - Size and degree of security.
Abstract: The dynamic growth in the field of Information communication has hiked the ease of Information transmission. But this type of real advancement in other sense has explored so many possibilities of information being snooped, at the time of communication in between the sender and the intended receiver. So, day by day Information Security is becoming an inseparable part of Computing and Communication. Various tools are available in order to address those issues and in them Steganography plays a significant role. In this paper, a heuristic approach for Information hiding in the form of multimedia objects or text using Steganography is proposed keeping in mind two considerations - Size and degree of security. Here, the Information is hidden behind an image in the form of an encoded matrix which is obtained from the bit matrix of the embedded object.
