MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611112500 A) filed by Pradumn Kapil on September 18, 2026, for Digital Media Provenance Systems And Related Methods.
Inventor includes Pradumn Kapil.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A system and method (100, 200) may establish digital media provenance by capturing media data, computing a content descriptor before signature embedding, and assembling a composite signature including a non-exportable unique identifier, the content descriptor, a capture timestamp, and a hardware-backed device signature. A steganographic coder (120) may divide the media data into carrier units and redundantly embed chunks of the composite signature before a retrievable unsigned file is accessible. A registration server (140) may publish signed registry snapshots with log-root commitments, record device attestation certificates, and monitor signing-rate and geographic-plausibility patterns for revocation. A verifier module (130) may extract the composite signature, validate a device or group signature offline, compare descriptors, generate a tamper indication, and report verification states based on payload-layer recovery.
