New Image Encryption Method Based on two Stage Scrambling

New Image Encryption Method Based on ICA

Shot change detection is an essential step in video content analysis. However, automatic shot change detection often suffers high false detection rates when there are camera or object movements. In this paper, we propose an approach to solve this problem based on local keypoint matching of the video frames. Experimental results show that the proposed algorithm is effective for all kinds of shot...

Effect of Pixel Scrambling Method on Image Encryption

Four Level Image Encryption Using Scrambling and Key Based Methods

In this study, we present a novel image encryption algorithm based on four level hash based encryption. Our approach integrates scrambling scheme with hash based methods which masks the image signal and make it more secure. The resulting system can securely encrypt the images for the purpose of storing images and transmitting them over the Internet. There are two major advantages associated wit...

Image Encryption using Curved Scrambling and Diffusion

In the recent world, designing of a secure cryptosystem is prime focused area for the researchers. This paper emphasizes on the image encryption/decryption technique using a key derived from a plain image. In the proposed algorithm, encryption key is derived by applying new curved scrambling method to the RGB layers of a plain image. In next step, a temporary cipher image is obtained by modulo ...

Image Encryption Using Block Scrambling Technique

Due to the rapid growth of digital communication and multimedia application, security becomes an important issue in data exchange process over the wide network. In this paper, an efficient technique is presented with the help of cipher block chaining (CBC) operation ,which is used for image encryption. We test our proposed technique using MATLAB R2010a, it can achieve various image quality para...
