Privacy-Preserving Proof of Human Authorship via Zero-Knowledge Process Attestation
David Condrey
Process attestation verifies human authorship by collecting behavioral biometric evidence, including keystroke dynamics, typing patterns, and editing behavior, during the creative…
A TEE-Based Architecture for Confidential and Dependable Process Attestation in Authorship Verification
David Condrey
Process attestation systems verify that a continuous physical process, such as human authorship, actually occurred, rather than merely checking system state. These systems face a f…
Detecting Cognitive Signatures in Typing Behavior for Non-Intrusive Authorship Verification
David Condrey
The proliferation of AI-generated text has intensified the need for reliable authorship verification, yet current output-based methods are increasingly unreliable. We observe that…
PoSME: Proof of Sequential Memory Execution via Latency-Bound Pointer Chasing with Causal Hash Binding
David L. Condrey
We introduce PoSME (Proof of Sequential Memory Execution), a cryptographic primitive that enforces sustained sequential computation via latency-bound pointer chasing over a mutable…
Witnessd: Proof-of-process via Adversarial Collapse
David Condrey
Digital signatures prove key possession, not authorship. An author who generates text with AI, constructs intermediate document states post-hoc, and signs each hash produces a sign…
On the Insecurity of Keystroke-Based AI Authorship Detection: Timing-Forgery Attacks Against Motor-Signal Verification
David Condrey
Recent proposals advocate using keystroke timing signals, specifically the coefficient of variation () of inter-keystroke intervals, to distinguish human-composed text from AI-…
