ENCRYPTION AND DECRYPTION TECHNIQUE WITH SMS SUPPORT FOR DIGITAL IMAGE SECURITY

Abstract

With the rise in the use of digital techniques of transmitting and storing images, it becomes an important issue to look into how to protect the confidentiality, integrity, and authenticity of such images. There are various techniques to encrypt images and make them more secure, including Image encryption techniques that scramble the pixels of images and decrease the correlation among the pixels so that there are lower correlations among the pixel of the encrypted image. Encryption generally converts data or information from its original form to another in order to hides the information in it. The protection of images from unauthorised access is critical and essential. In this study, in order to address the issue of image security, an application was developed using encryption and decryption algorithm with SMS technology. This application sends messages containing the encryption and decryption key to the mobile phone of the intended/final owner of the image specifying the key for opening the file sent and the key is shared by both encrypted and decrypted image. The application developed using this algorithm is intended to provide the security so desired.
