Secure Image Transmission for Mobile Application Using PSNR Metric and Elliptic Curve Digital Signature

The industry of mobile applications is mostly seeing an increase in upgrades. These days, mobile applications are utilized across several platforms on single-handed devices. Additionally, attackers can employ comparable technologies to conceal their identity and anonymize their malicious conduct. Security is crucial as a result. We emphasize on sensitive secure encryption and decryption approaches in this article, like the PSNR metric and the elliptical curve digital signature algorithm, to ensure safe transfer of images that are private between the mobile stations. These algorithms will be used to create a defensive application. In order to enhance secure transmission, this article will employ four distinct technological tiers. Choosing a hidden picture is the first stage. Different file formats will be supported by the hidden image. Using an encryption method, the picture obtained from the first degree of security is encrypted at the second level. The overarching objective of the project is to provide a comprehensive approach that effectively shields private photographic information from potential threats in the rapidly evolving sector of mobile computing. The third stage includes working out the image's LSB and 3m (Mean, Median, Mode) with the aim to mask the message beneath the cover image. The final security step involves compressing the resulting stenographic image with GZIP. An oval curve and a digital authentication procedure have been employed to strengthen a security strategy. As a result, it is advised to use this technique to convey a covert message via applications that are particularly significant across mobile applications.
