A UNIQUE TECHNIQUE FOR MOBILE IMAGE ENCRYPTION

Abstract

Improvements in the realm of mobile apps are on the rise. In addition to their widespread usage on multi-platform mobile devices, Intruders may use comparable technologies to obfuscate their malevolent actions and conceal their identities. Accordingly, safety is paramount. To ensure the safe transfer of sensitive images across mobile nodes, this project prioritizes the use of precautionary encryption and decryption methods such as the PNSR metric and the elliptic curve digital signature algorithm. We will build a defensive app using these algorithms. This project aims to enhance secure transmission by using four distinct tiers of technology. Secret picture selection is the first level. File formats such as jpg and png will be compatible with the hidden image. Using an encryption technique, we encrypt the picture obtained from the first level in the second layer of security. In this case, the PSNR metric is used to quantify the picture quality. The third stage involves identifying the LSB and 3m (Mean, Mean, Mode) of the image in order to conceal the message within the cover image. The last step in security is to compress the resulting stegnographic picture using GZIP. To improve a security procedure, one uses an elliptic curve, which is a digital signature technique. Hence, this is the recommended way to transmit a covert message across critical mobile apps.
