Detect Risk Through Behavioural Analysis at Scale
Airport screening analysis identifies stress, deception and cognitive load signals in individuals passing through security checkpoints — using standard camera infrastructure, no contact and sub-second latency. EchoDepth applies the FACS standard at screening scale.
Current screening technology monitors bags and bodies. The behavioural signal goes unread.
Metal detectors, X-ray and biometric systems address physical threats. Behavioural threat detection — the stress, deception and cognitive load signals that precede incidents — is largely dependent on individual officer observation.
Officer observation is inconsistent, fatigues over shift duration, and is subject to the same unconscious bias patterns as any human assessment. It cannot be audited or scaled.
Polygraph has no scientific consensus and is legally inadmissible in UK courts. There is no current defensible, evidence-based alternative for assessing credibility during security interactions.
High-throughput environments make individual observation impractical. The volume that requires analysis exceeds what officer capacity can address.
EchoDepth provides a behavioural risk signal that can prioritise secondary screening decisions — identifying individuals displaying stress, deception or cognitive load patterns that warrant additional assessment.
Generate timestamped AU analysis during security interviews. Provide investigators with a structured, auditable record of behavioural signals — a defensible alternative to subjective observation.
Compare officer behavioural assessments against EchoDepth signal data. Identify inconsistencies in officer assessment and calibrate screening standards.
Questions
Is airport screening analysis ethical and legal?
EchoDepth operates under a consent-first architecture. Deployment in public security environments requires legal authority, proportionality assessment, and compliance with the UK Data Protection Act 2018 and ICO guidance on biometric data. Cavefish provides full legal and governance documentation for every security deployment. We engage only with government-authorised security operators.
Does EchoDepth detect lies?
No. EchoDepth measures the physiological markers that accompany stress, cognitive load and emotional state change — it does not detect deception. The distinction is critical: EchoDepth provides evidence of behavioural state, not intent. Human judgment and due process remain essential.
What cameras does this require?
EchoDepth works with standard RGB cameras at typical security checkpoint resolution. No specialist hardware, no contact, no wearables. The system integrates with existing CCTV and checkpoint camera infrastructure.
What is the accuracy at scale?
EchoDepth is calibrated across 14 cultural cohorts in 6 countries to address the demographic bias that uncalibrated systems introduce. Accuracy claims in screening contexts depend on specific deployment conditions — contact us for a technical briefing on your specific environment.
