Providing High Security and Recovering Good Quality Image using Visual Cryptographic Technique
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 5
Abstract
Abstract: Security is an important factor, since many digital images are transmitted through internet, which contains secret information. Symmetric and Asymmetric methods are two types of cryptographic techniques used to encrypt and decrypt the confidential data. Conventional encryption technique is one of the methods usedto transmit secret image which has a drawback of maintaining the secret key. Image splitting is another technique used, in which secret image is divided into different share images. Individual share does not reveal any information about the secret. Qualified set of shares are used to decrypt and get back the original image. Quality of the recovered image and security are the two major issues of this technique. In this paper, we proposed the cryptographic technique which uses three steps for encryption. Encryption process creates two shares, which are like random noise. Shares are transmitted to receiver and shares are decrypted separately and combine both the shares to obtain the original secret image. Proposed method increases the security level and the quality of decrypted image is same as that of original secret image
