Technical Architecture and Annexes of the Book "The Digital DNA of Images"

In the era of deepfakes and AI-generated content, digital authenticity has become a critical global issue.Micaël Lanoix, inventor of the concepts PNGIA, Pixel 4D, and Digital DNA (Digital Detection Agent), presents in this technical annex the architectural foundation of a new digital standard for image authentication and traceability. The PNGIA system introduces a 4-dimensional pixel structure that embeds cryptographic integrity and provenance metadata directly into the image file.Through the combination of cryptography, artificial intelligence, and blockchain anchoring, each image becomes self-verifiable, tamper-evident, and permanently traceable. This document consolidates the technical annexes of the book “PNGIA: The Digital DNA of Images”, detailing the algorithms, data structures, and verification protocols forming the core of this innovation.It establishes the theoretical and practical framework for a new generation of media integrity systems, where digital truth becomes measurable, verifiable, and sustainable.
