MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641017325 A) filed by Easwari Engineering College; and Srm Institute Of Science And Technology, Chennai, Tamil Nadu, on Feb. 17, for 'dual-layer secure messaging framework integrating aes encryption and image-based steganography.'
Inventor(s) include Aditya S; Aravindhan G; and Mrs. M. Bhuvaneswari.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The system also facilitates secure transmission of messages through a combination of AES encryption and LSB steganography. The AES encryption is used to encrypt messages, and then LSB is used to hide messages, making them invisible to hackers trying to intercept messages over a web network. The web app is a Flask app that does not require installation because it is browser-executable. The sharing of encryption keys is facilitated by generating a QR code, thus eliminating any vulnerabilities associated with manually sharing keys. The system has also adopted SHA-256 hash verification, which ensures image integrity by checking for any attempts to compress, alter, or tamper with images before decryption. Key features include user authentication, sessions, a persistent inbox for message storage, and notifications. Unlike existing systems, which either facilitate encryption or steganography, this proposed system offers both techniques along with other practical features like integrity verification and secure key exchange."
