MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202521125015 A) filed by Dr. Damodar Tiwari; and Dr. Anvesh Singh, Bhopal, Madhya Pradesh, on Dec. 11, 2025, for 'a system and method for authenticating digital image ownership using adaptive invisible watermarking.'
Inventor(s) include Dr. Damodar Tiwari; and Dr. Anvesh Singh.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The invention discloses a system and method for authenticating digital image ownership using adaptive invisible watermarking combined with cryptographic verification. The system includes an image preprocessing module that identifies optimal embedding regions, an adaptive watermark embedder that selects embedding strength based on local image features and human visual perception, an ownership signature generator that produces a cryptographically secure signature, and a secure watermark mapper that encodes the watermark redundantly across spatial and frequency components. The watermark extraction and verification engine reconstructs the embedded watermark from potentially altered images and validates ownership by comparing the extracted signature with the original. The system further includes a tamper detection unit and an optional decentralized ledger interface for immutable proof of ownership. The invention provides robust, invisible, and tamper-resistant watermarking suitable for various digital imaging platforms, ensuring reliable ownership authentication under real-world conditions."
