MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641046901 A) filed by Agni College Of Technology, Chennai, Tamil Nadu, on April 13, for 'quantum-resilient multimedia blockchain framework with steganographic privacy preservation and cloud-enabled distributed verification.'
Inventor(s) include Revathi K; Preethika C; Shakthi Aravindhan V; Srinidhi C; and Sudharsan K.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A Privacy- Preserving Post-Quantum Blockchain Architecture is suggested in this study that incorporates the steganography, AWS cloud services and MATLAB-based video processing to transmit and store data in a secure fashion. The traditional blockchain technology is becoming more susceptible to quantum computing attacks that pose a threat to classical cryptographic systems. In order to solve this, the proposed structure implements post-quantum cryptographic algorithm and hides sensitive transaction/identity data inside the video frames with state of the art steganographic algorithms. Feature-level security analysis of embedded videos is done using MATLAB and verified and range of storage is offered by AWS on a scaled and distributed manner. Through experimental means, strong quantum-resistant data encryption, capacity to embed large amounts of data, and little visual impairment of multimedia material are realized. The hybrid system proposed guarantees confidentiality, integrity, and immutability, which facilita."
