WITNESS · Physical security sensing

UK-hosted. Embedding-only. No facial-recognition store.

The sovereignty signature of TicketWave Witness. Every hop, every residency claim, every regulator's first question — answered on one page. If the topology below doesn't match what your DPO needs to sign off, we'd rather know before the pilot, not after.

ReID via embeddings is not the same as facial recognition.

The Information Commissioner's Office has been explicit on automated facial recognition in private settings: the Facewatch decision (December 2024), the South Wales Police Bridges case, the Serco custody-suite contract. All three turn on whether a facial template is extracted, stored or matched. We extract none of those.

What we compute is a 512-dimensional float vector that summarises body shape, gait and clothing colour. A human cannot reconstruct a face from it. A second AI model can't reconstruct a face from it without training data we don't collect. It is not a biometric template under the UK GDPR Schedule 1 special-category meaning.

We hold written legal opinion from a UK data-protection specialist to that effect. The opinion is shared with customers under NDA during the pilot enquiry.

The 30 June 2026 audit. Pre-mapped.

The Data Security and Protection Toolkit v8 is the NHS-aligned control framework that becomes mandatory for relevant care and adult-care-adjacent settings on 30 June 2026. Build-to-rent operators with assisted-living elements; boutique hotels with care or wellness adjuncts; venues hosting CQC-regulated events — all increasingly within scope.

  • § 01 · DATA SECURITY

    Embedding store hardening

    AES-256-GCM at rest. TLS 1.3 in transit. UK region only. No backup snapshots leave the jurisdiction.

  • § 02 · ACCESS CONTROL

    Per-role, per-camera, per-window

    Operators see only the cameras they're assigned. Reviewers see only the events flagged in their window. Admins see audit logs; nobody sees raw embeddings.

  • § 03 · INCIDENT

    72-hour breach posture

    Customer notified within 24 hours of any embedding-store breach. ICO notification window of 72 hours is met by default; we draft the notification, the customer files it.

  • § 04 · STAFF

    Quarterly training, annual attestation

    Every staff member with embedding-store access completes the DSPT v8 awareness module quarterly and signs an annual attestation. Records held in the customer's audit pack.

What the DPO asks first.

  • 01

    Is this facial recognition?

    No. We compute a 512-dimensional embedding from body shape, gait and clothing colour. We don't extract or store a facial template under the UK GDPR Schedule 1 special-category meaning. The ICO has been explicit that automated facial recognition needs an Article 9 lawful basis. ReID via embeddings is a different category of processing.

  • 02

    Where is the data?

    Edge inference runs at the LHR (London) region. Embedding vectors are stored in the UK region with a 14-day expiry. Raw frames are held in a 30-second rolling buffer on the edge node and never persisted. No US transit at any hop.

  • 03

    Are you DSPT v8 ready?

    Yes. The Data Security and Protection Toolkit v8 audit becomes mandatory on 30 June 2026 for relevant care and adult-care-adjacent settings. Our control mappings are built for the v8 controls and shared with the customer's auditor before the assessment window opens.

  • 04

    Who is the data controller?

    The customer is the data controller. We are the processor. ICO ZA-registration is in progress; we'll publish the ZA number on this page on issuance.
