The Human Fingerprint Protocol Thermodynamic Verification of Biological Cognition in Digital Environments
Richard G. Prouse
ABSTRACT
As of Q1 2026, the digital economy faces a structural crisis of “Cognitive Provenance.” The proliferation of Agentic AI, driven by advanced Transformer architectures, has rendered legacy verification methodologies statistically obsolete. This paper presents the theoretical framework and operational methodology of The Sentinel, a forensic engine designed to verify human presence through Multifractal Detrended Fluctuation Analysis (MFDFA) and Linguistic Thermodynamics. By quantifying the specific entropic signatures of biological motor control (Pink Noise, 1/f) and cognitive load, we establish a deterministic standard for distinguishing biological intent from algorithmic emulation. Empirical simulations indicate that biological cognition exhibits a persistent Hurst Exponent (0.55 < H < 0.95) and Staccato Variance (CV ≈ 1.0), markers that current synthetic agents fail to replicate without stochastic collapse.
