MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541123371 A) filed by Ms. Shaini. A; Ms. L. Dharani; Dr. V. Kaliraj; and S. A. Engineering College, Chennai, Tamil Nadu, on Dec. 8, 2025, for 'hybrid multi-domain steganography system with cryptographic protection and adaptive embedding selection.'
Inventor(s) include Ms. Shaini. A; Ms. L. Dharani; and Dr. V. Kaliraj.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a hybrid multi-domain steganography systemwith cryptographicprotection and adaptive embedding selection for secure digital data communication. The systeminitially encrypts the secret payload using a robust cryptographic algorithm to ensure confidentiality, followed by distributing the encrypted data across both spatial and frequency domains of the covermedia. An adaptive embedding mechanism intelligently selects high-texture and visually insensitiveregions to maximize imperceptibility and maintain media quality. The hybrid domain approachenhances robustness against compression, noise addition, filtering, and advanced steganalysis attacks. Additionally, integrity verification is incorporated to detect tampering during transmissionor storage. The proposed invention significantly improves security, payload reliability, and visual qualitycompared to conventional single-domain steganographic techniques, making it suitable for critical applications such as defense communication, medical data protection, and secure multimediatransmission."
