IDTP is a Maryland-based consulting and technical-services company specializing in biometrics, smart cards, identity systems, and credentialing. Its role appears to be advisory and technical rather than the mass production of credentials or airport screening equipment. A TSA security threat assessment is the vetting process used to determine whether an applicant is eligible to receive or retain certain transportation credentials or authorizations. TSA uses biographic and, in many programs, biometric information to check applicants against criminal, immigration, intelligence, and national security records.
