Total Recall: Implicit Learning as Cryptography

Memory and Authentication

Cognitive memory operates through three stages: encoding (converting information into memory), storage (maintaining memories), and retrieval (accessing stored information). Understanding these mechanisms enables novel authentication approaches.

Authentication Beyond Traditional Passwords

Standard password-based authentication has a critical flaw: under duress or torture, users can be coerced to reveal credentials. The talk explores authentication schemes that exploit memory limitations to create credentials users cannot consciously reveal.

Implicit Learning and SISL Training

Serial Interception Sequence Learning (SISL) training embeds passwords into implicit memory through repeated exposure and pattern recognition, distinct from explicit memorization. Implicitly learned sequences are harder to consciously access or articulate.

Forensic Hypnosis and Memory Recovery

The research considers whether forensic hypnosis could extract implicitly learned passwords. The speaker reviews current research on memory recovery and the practical security implications of this emerging authentication paradigm.
