an audit log implemented by the one or more processors and configured to persistently record each authorization determination, including the identity of the requesting entity, an authorization outcome, a timestamp, and a permitted or denied operation within the permitted usage scope, the audit log being queryable by the real individual or the designated rights holder;

a Data Ingestion Module implemented by the one or more processors and configured to receive and process multimodal data comprising one or more of photos, videos, audio recordings, written content, and behavioral profiling data, the Data Ingestion Module being operable only upon a prior positive authorization determination by the Licensing & Usage Management System;

The system of claim 1 , wherein the Licensing & Usage Management System supports monetization models selected from the group consisting of per-session access, subscription access, and non-fungible token-based (NFT) licensing, wherein each monetization model is conditioned on a prior positive authorization determination from the license verification engine and each transaction is recorded in the audit log.

11 . The system of claim 1 , wherein the Rendering Engine synchronizes lip movement of the AI avatar to the synthesized speech output.

12 . The system of claim 1 , wherein the Rendering Engine triggers avatar animations based on real-time analysis of user sentiment and conversational context.

13 . A method for creating and deploying an interactive artificial intelligence (AI) avatar of a real individual, the method comprising the steps of:

performing, by a Licensing & Usage Management System, an identity-linked consent evaluation prior to any avatar synthesis, interaction, or deployment, comprising: retrieving one or more authorization records from a consent registry associated with the real individual or a designated rights holder;

verifying a license key and authenticating an identity of a requesting entity against the authorization records to produce an authorization determination, including enforcing time-based access control constraints;

persistently recording the authorization determination in an audit log, an audit log entry comprising the identity of the requesting entity, an authorization outcome, a timestamp, and a permitted or denied operation within a permitted usage scope;

receiving, by a Data Ingestion Module, multimodal data associated with the real individual comprising photos, videos, audio recordings, written content, and behavioral profiling responses, only upon a prior positive authorization determination;
