MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202621107079 A) filed by Ayushi Dubey; Madhu Nagar; Shubham Sharma; and Madhuri Hardia on September 05, 2026, for Forensic Tamper-Evident Evidence Management System With Cryptographic Chain-Of-Custody Verification.
Inventors include Ayushi Dubey; Madhu Nagar; Shubham Sharma; and Madhuri Hardia.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention discloses a forensic evidence integrity and provenance system (100) for tamper-evident management of digital evidence. The system comprises an acquisition module (110) with cryptographic hashing and manifest generation, an evidence repository module (120) with immutable storage and encryption, an event ledger module (130) recording hash-chained and digitally signed custody events, a time and trust module (140) providing trusted timestamps and certificate validation, a provenance layer module (150) tracking derivation relationships between evidence entities, and a review and export module (160) generating human-readable verification reports. A role-based access control module (170) enforces separation of duties, while a verification engine (180) enables independent integrity verification through hash recalculation, signature validation, and hash chain reconstruction. The architecture separates evidence data, custody metadata, and identity services to prevent single-point compromise.
