AISIS for diamond security and internal investigations.
AI-assisted review for structured, examiner-led interviews in high-value mineral environments.
- Examiner-led
- Trained professionals remain responsible for questions, review, and conclusions.
- Portable
- Designed for authorized investigative work in offices, facilities, or field environments.
- Evidence-led
- Stress-related indications guide clarification and corroboration, not a verdict.
Operational relevance
When a security issue needs disciplined interviews.
In a high-value diamond environment, a loss, discrepancy, access irregularity, or suspected internal collusion may involve many people and limited physical evidence. AISIS gives trained examiners an additional source of structured information while they assess the full investigative record.
Potential operational applications
- Suspected diamond theft, diversion, or unexplained loss
- Vault, inventory, access-control, and chain-of-custody discrepancies
- Security-procedure violations and irregular handling or movement
- Interviews involving employees, contractors, drivers, couriers, vendors, and security personnel
- Internal collusion, corruption, organized theft, or deliberate security failures
- Post-incident interviews where additional clarification or corroboration is needed
AISIS in practice
Technology supports the examiner, it does not replace the investigator.
AISIS presents stress-related vocal information during a structured interview. It can help identify responses that may warrant clarification, further questioning, or corroboration through access records, surveillance, physical evidence, witness statements, and other investigative sources.
No AISIS or VASIS result independently determines whether a person is truthful or deceptive. The examiner remains accountable for the process and its interpretation.
- PrepareDefine the issue, establish clear questions, and document suitable interview conditions.
- ReviewConsider vocal information alongside question wording, timing, context, and the full interview record.
- CorroborateTest any follow-up lead through independent evidence before reaching an investigative conclusion.
