Advanced Partial Image Encryption using Two-Stage Hill Cipher Technique
Information security is a fast growing research field which includes numerous problems in it. Partial image encryption is one of the important problems in the field of image information security. This paper describes the partial image encryption in two ways using hill cipher technique. First encryption technique uses two slightly different keys to construct two self-invertible matrices, which a...

متن کاملSteganography- A Data Hiding Technique
Steganography is the art of hiding information and an effort to conceal the existence of the embedded information. It serves as a better way of securing message than cryptography which only conceals the content of the message not the existence of the message. Original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable. In this paper we w...
متن کاملImage Hiding Algorithms Based on Halftoning Technique
Halftoning technique is used to convert a continuous-tone image into a binary image with pure black and white pixels. This technique is necessary when printing or displaying a monochrome or color image by a device with limited color levels. The main contribution of this paper is to present a halftoning method that conceals a small binary image into a large binary image. More specifically, two d...
متن کاملA Novel Approach of Steganography using Hill Cipher
In the modern technological world, where data or image transfer through the internet has gained utmost importance, security of the data has become a major issue. We use cryptography for the security of the above mentioned data. By the help of cryptography, we convert plain text into cipher text, or data that is unreadable to the attacker. Another approach is to hide data in image and then send ...
