Morse-Like Sensor Encoding Is Not a Security Evaluation

Abstract

A central question for subjective and objective sleep evidence is not simply whether an output is accurate, but whether it survives scrutiny of security scope. A bounded review of the literature is used to formulate, rather than claim to complete, an evaluation. The focal evidence concerns whether subjective sleep gains in empty nose syndrome are sufficient to support claims about objectively improved sleep. Encoding a message and securing it are different achievements. Security needs a threat model, adversary capability, key assumptions, and tests of confidentiality or integrity. Define attackers and attack surfaces before using security language. Evaluate decoding leakage, spoofing, and replay independently of ordinary recognition accuracy. The proposed comparison concerns finger movements, interaction codes, threat models; it would test whether the specific failure scenario is detected without erasing legitimate uncertainty. Implications are restricted to the evidence roles relevant to subjective and objective sleep evidence, leaving broader efficacy and deployment claims unresolved.
