ACCESS CONTROL MECHANISM BASED MESSENGER APPLICATION FOR SECURE COMMUNICATION USING AES ENCRYPTION METHODOLOGY

Abstract

Messaging application is among the most popular applications for smartphones. These essentially eliminate client's conversation expenses because they can initiate phone conversations and send texts via the Internet. Practically everyone who owns a smartphone uses these apps. Unfortunately, like every other type of application, the majority of these contain integrity and confidentiality flaws and can be attacked by hackers. Thus, the technology of using cryptography for transmitting information—in which the texts are encrypted and sent by the sender—makes this application unique. The encrypted message is also sent to the recipient. After the authentication and validation phase is finished, the message is decrypted. We employ the access control mechanism for this procedure. It is a system that restricts access to the decrypted message or message session to only those who are permitted. For the highest level of protection, we can employ the iris/face recognition technique. Only when the authenticated the individual's face matches the pre-registered credentials the message will be encrypted. The combination of encryption and access control mechanism offers this messaging app the highest level of privacy.
