A secure messaging application using steganography and AES encryption a dual-layer secure messaging system

Abstract

This research involves the development of a secure messaging application with the capability to send messages inside images oraudiofiles using the practice called steganography. In this application, a person can secretly communicate in such a way that nooneisawareoftheexistenceof the hidden message. The application uses the Least Significant Bit (LSB) method to hide the messages while encrypting the messages. To provide greater security, AES encryption is used before hiding the messages, thus forcing both sender and receiver to decrypt the message using a shared key. This two-layer approach of steganography and encryption creates this application highly appropriate for people with communication controls or monitored at some level because it gives confidentiality for the message privacy.
