Share No More Than the Request Requires: Federated Disclosure for Perspective-Aware AI

2026-07-24

AI Summary

This work addresses the problem of excessive disclosure of user context in cross-domain data requests by proposing the Provenance Preserving Chronicles (PPC) protocol, which establishes a user-sovereign identity model grounded in temporal knowledge graphs. Integrating relation-aware views, domain ontologies, and explicit authorization workflows, PPC employs federated access control and a two-phase disclosure mechanism to share only the minimal subset of data necessary for a given task while enabling verifiable provenance. The study introduces the first formal framework for the cross-domain minimal disclosure problem, bridging a critical gap in holder-centric sovereignty design within blockchain and peer-to-peer systems. A prototype implementation demonstrates the protocol’s effectiveness in preserving data sovereignty and ensuring regulatory compliance.

Abstract

Modern AI systems bring societal risks such as mass surveillance, extreme concentrations of power, and loss of user autonomy---calling into question a model where third-parties collect and control massive amounts of user data. Users require a sovereign system to securely own, govern, and disclose their context while remaining compliant across regulated domains with strict provenance, interpretability, and policy adherence. Perspective-aware AI approaches this by transforming a user's aggregated personal data into a structured identity model called a \emph{Chronicle}: a temporal knowledge graph that represents and grows with the user. Chronicles support the secure disclosure of context across federated networks. A Chronicle holder may expose a queryable, authorized view that a third-party agent may consult without centralizing anyone's data. This paper explores the problem of minimum-necessary disclosure across domain boundaries: when a requester's agent queries a Chronicle, how can the system constrain its response to release only what the requester's relationship, stated purpose, and specific task require? We propose \textbf{Provenance Preserving Chronicles} (PPC), a federated protocol that compiles each holder's Chronicle into a compact \emph{authorized evidence subgraph} governed by one rule: \emph{share no more than the request requires}. Holders keep local sovereignty; an access controller projects relationship-aware views over domain-expert ontologies; and a two-phase flow returns provenance-linked text first, releasing raw artifacts only after explicit holder approval. We frame the problem, map gaps in blockchain, P2P, and holder-sovereign designs, define the core constructs, and sketch the protocol with an explicit threat model.
