DHDNA: A Framework for Ethical Digital Identity as Inheritable Heritage

We present DHDNA (Human Digital DNA), a novel framework for treating digital identity as inheritable heritage rather than exploitable data. As digital footprints expand across thousands of platforms, current approaches focus exclusively on authentication and security, neglecting the preservation of meaning, continuity, and ethical use. We introduce five core innovations: (1) Narrative Topology — a mathematical framework for mapping personal meaning across digital interactions; (2) Cognitive Genome Encoding — a dynamic representation of individual values and decision patterns; (3) Temporal Identity Architecture — maintaining coherent identity across past, present, and future states; (4) Heritage Protocols — legal and technical frameworks for digital inheritance; and (5) E-Cortex Integration — enterprise infrastructure for ethical AI validation. We describe our implementation consisting of 38 cognitive modules, 12 applications, and a comprehensive governance framework. We argue that digital identity infrastructure represents a civilizational challenge requiring ethical foundations fundamentally different from current data-centric approaches.
