Suspect Detection Systems Inc.'s Cogito Data Center (Cogito DC) is a central knowledgebase and control server that serves as a complete analytical back office to the Cogito Rapid Interrogation System. Cogito DC will enable SDS customers to create a central storage base of all examinee data. The interrogation system collects an vast amount of data with each examination beginning with a scan of the examinees passport or identification card. The system then scans unique biometric identification information including fingerprint and iris (eye) imaging, and voice signature. The Cogito DC knowledgebase then aggregates and analyzes the interrogation results of all examinees. The system compares test results of potential suspects from common backgrounds, which then enables interrogators to perform intelligence analysis over the entire scope of collected metadata.
