Survey on Wavelet Based Image Encryption and Decryption

Manju Lakshmi ^[2] | Smita C Thomas ^[2] | Sreelakshmi K ^[4]

Abstract: The process of transmitting image encryption using the image securely over the network so that an unauthorized user cannot able to decrypt the image. Different techniques for using image encryption. The most common method of image encryption is wavelet transform. Wavelet transform of the image generates the different components basically classified in the approximation and detail components. The approximation component has major information. A partial encryption technique is using only approximation component. The decryption techniques used a key for decryption. In this paper say that survey of different wavelet based image encryption and decryption techniques.

Keywords: image encryption, decryption, MSE, DWT, CWT, PSNR,
