According to the abstract released by the Intellectual Property India: "Secure Pixel Blockchain based Authentication for Digital Image Integrity 2. Abstract The present invention relates to a secure pixel-level blockchain-based authentication system for ensuring the integrity and authenticity of digital images. The proposed approach embeds cryptographic hash information derived from individual pixel values or pixel blocks into a blockchain framework, enabling tamper-resistant verification of image content. Each image or image segment is uniquely represented through secure hash generation and immutably recorded on a distributed ledger, ensuring traceability and non-repudiation. Any modification to pixel data results in a mismatch between the stored blockchain record and the current image state, thereby enabling reliable detection of unauthorized alterations. The system enhances data security by combining pixel-level integrity verification with decentralized blockchain authentication, eliminating reliance on centralized authorities. The proposed method is applicable to digital forensics, medical imaging, legal evidence management, surveillance systems, and secure multimedia communication, where image integrity and authenticity are critical. Keywords Digital image integrity, Blockchain authentication, Pixel-level security, Cryptographic hashing, Tamper detection, Distributed ledger technology."
