MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202641065595 A) filed by Dr. D. K. Sheena Christy; and Abdul Alima, A on May 25, 2026, for Adaptive Medical Image Encryption Using Hyperchaotic System With Hypergraph Grammar Rewriting.
Inventors include Dr. D. K. Sheena Christy; and Abdul Alima, A.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: ABSTRACT I The present invention proposes an adaptive medical image encryption framework using hyperchaotic system dynamics and hypergraph grammar rewriting. Medical images are transformed into hypergraph structures and recursively evolved using adaptive graph grammar production rules controlled by a five-dimensional hyperchaotic system. The evolving graph topology generates adaptive pixel permutation, graph-derived keystreams, and diffusion operations for secure medical image encryption. The proposed invention provides topologyaware region-sensitive encryption suitable for MRT, CT, PET, and telemedicine imaging systems while improving randomness, entropy evolution, and resistance against statistical and differential cryptographic attacks
