draft-ayerbe-trip-protocol-04 has been posted, with Muhammad Usama Sardar
(TU Dresden) joining as co-author.

The substantive change is a new Appendix A positioning TRIP relative to the
four parallel geo-location proposals in RATS and WIMSE -- per the
commitment made to this list in February.

Feedback welcome.

Thanks, Camilo

Abstract:

   This document specifies the Trajectory-based Recognition of Identity
   Proof (TRIP) protocol, a decentralized mechanism for establishing
   claims of physical-world presence through cryptographically signed,
   spatially quantized location attestations called "breadcrumbs."
   Breadcrumbs are chained into an append-only log, bundled into
   verifiable epochs, and distilled into a Trajectory Identity Token
   (TIT) that serves as a persistent pseudonymous identifier.

   The protocol employs a Criticality Engine grounded in statistical
   physics to distinguish biological movement from synthetic
   trajectories.  Power Spectral Density (PSD) analysis detects the 1/f
   signature of Self-Organized Criticality in human mobility through the
   PSD scaling exponent alpha.  A six-component Hamiltonian energy
   function scores each breadcrumb against the identity's learned
   behavioral profile in real time.

   This revision (-03) addresses three areas identified through expert
   review by researchers in the statistical physics community: it
   replaces informal terminology with standard spectral analysis
   nomenclature; it provides the analytical and numerical bridge between
   the Levy flight displacement exponent and the PSD scaling exponent;
   and it introduces a convergence analysis framework for quantifying
   the minimum trajectory length required for reliable single-trajectory
   classification.  Additionally, this revision removes Passive
   Verification mode entirely, requiring all Attestation Results to be
   bound to Relying Party nonces via the Active Verification Protocol.

   TRIP is designed to be transport-agnostic and operates independently
   of any particular naming system, blockchain, or application layer.
