“…The extracted image will be having dual shares. These dual shares will give the original image.In [11], the author proposed model the input image is a plain image in which a function has been applied to obtain the secret key. The secret key is used to shuffle the pixels on the plain image based on an algorithm and it produce the ciphered image which can be stored or transmitted.…”

Secure storage and easy retrieval of data is major concern for patients when medical data is stored over cloud platform. The unique features of cloud environment are high performance, data availability and security among which security of data stored in cloud environment is sensitive it can be easily attacked by intruders. Concerning medical images, while storing data, proper secure authentication method should be applied in order to avoid misuse of medical data. When this medical image is retrieved, the clarity of retrieved image should be high in order to determine the exact cause of sickness. This paper focuses on proposing a secure storage and retrieval of medical images stored in cloud with visual cryptographic technique using AES algorithm. The experimental results show that the proposed system is able to store images securely and retrieve medical images with high clarity.

The role of internet became a non replaceable one in our day to day life. Internet users also face various security threats such as eavesdropping and unauthorized access through intrusion. Internet users need to be protected and provided privacy. Network security and image encryption has become important and high profile issues. Various cryptographic techniques are already available in literature for secured data transmission. Image encryption is still a major area of research with extensive effort being spent in determining a standardized image encryption technique that is difficult for hackers to crack the image. Hence the proposed work aims at developing an effective and standardized image encryption technique. At the transmission side it involves the following steps: subdividing an image in to n number of sub images of p x q, finding a suitable permutation/combination to interchange the pixels, merging the sub images in to a single image and transmitting it. At the receiver side the received encrypted image is subdivided in to n number of sub images of size p x q, the original pixel positions are obtained and the original image is formed. The effectiveness of the technique is measured in terms of correlation index and entropy for different rules of permutation. Finally the most effective permutation is identified which results in lesser correlation index and stronger entropy. The computational complexity of the algorithm is also analyzed.

RSA algorithm founded by Rivest, Shamir and Adleman is an algorithm that based on the use of factorization of a significant number to its factor, and the element must be the prime number. Factorization used to find the private key. In this paper, the RSA algorithm will be used in a visual cryptographic to encrypt and decrypt a color image. The test will conduct with five different photos. Assessment performed using Structural similarity (SSIM) to compare the matrix value of the initial image with the decrypted image. SSIM generates a value of 1 on all pictures. The proves that the Matrix Value in the initial and after decoded images has the same amount. The image decryption will worsen; can be seen from the smaller SSIM value.
