Securing Medical Images by Image Encryption using Key Image
This paper presents two methods for encryption and decryption of images using XOR operation. In the first method the original image is encrypted by the key image using XOR operation and decryption process also uses the same key image with XOR operation. In the second method one of the bit planes of the key image is used for encrypting the bit planes of the original image and shuffling is done f...
متن کاملImage Encryption by Using Combination of DNA Sequence and Lattice Map
In recent years, the advancement of digital technology has led to an increase in data transmission on the Internet. Security of images is one of the biggest concern of many researchers. Therefore, numerous algorithms have been presented for image encryption. An efficient encryption algorithm should have high security and low search time along with high complexity.DNA encryption is one of the fa...
متن کاملSegmentation of Medical Images using Image Registration
Medical image segmentation is one of the most essential task in many medical image applications, as well as one of the most complex tasks. Medical image segmentation aims at partitioning a medical image into its constituent regions or objects, and isolating multiple anatomical parts of interest in the image. The precision of segmentation often determines the final success or failure of the whol...
متن کاملA Visual Cryptographic Encryption Technique for Securing Medical Images
The increased growth in the use of transmission of multimedia medical contents over unsecured and open networks provides insecurity for confidential patient information over these networks. Digital encryption of medical images before transmission and storage is proposed as a way to effectively provide protection of patient information. Encryption before watermarking of these images is necessary...
متن کاملA Many-key Image Encryption Method Using the Lorenz System
A many-key chaotic image encryption scheme based on the Lorenz system is presented. Using the time-delay Lorenz system, the proposed approach performed the pixel permutation on a bit-by-bit basis in the diagonal and antidiagonal directions, providing the necessary pixel confusion. Then, the Lorenz system is employed again to generate a sequence of random bytes that are used in the diffusion ste...
