  1. Development of DICOS:Data Format and Transmission Standard for Security Screening NEMA - The Association of Electrical and Medical Imaging Equipment Manufacturers Defense Daily Open Architecture Summit November 18, 2010

  2. What is NEMA? • Founded in 1926 • ≈ 450 member companies in 55 sections (product categories) that manufacture products used in the generation, transmission and distribution, control, and end-use of electricity. • Medical Imaging & Technology Alliance (MITA), a division of NEMA, developed & maintains DICOM • a global information technology standard—used in virtually all hospitals worldwide • ensures interoperability of systems that produce, store, display, process, send, and retrieve medical images and manage related workflow. • ANSI-accredited Standards Developer • Manages 500 standards; about half are ANSI standards

  3. NEMA Objective • Maintain and extend DICOS airport security implementations, enabling scanning equipment interoperability • Ensure that DICOS capabilities extend to cargo screening and border protection activities to further the DHS/TSA mission

  4. Security Equipment Communication • DICOS enables sharing data among different vendors’ equipment. Data includes: • Images and metadata • Results of Automated Threat Detection (ATD) algorithms • Operator/TSO decisions

  5. Equipment Interoperability • With interoperability, screening equipment could produce, store, display, process, send, and retrieve information — without regard to manufacturer • Use different Automated Target Recognition (ATR) / Automated Threat Detection (ATD) algorithms as needed DICOS specifically addresses the interoperability challenge

  6. Member Manufacturers Analogic Corp. Applied Visual Sciences AS&E Aware Inc. Brijot Imaging DatCard Systems General Dynamics L-3 Communications NEMA Members • Optosecurity Inc. • Rapiscan Systems • Reveal Imaging • Safran/Morpho Detection • Siemens Corp. • Smiths Detection • SureScan Corp. • TeleSecurity Sciences

  7. Lawrence Livermore National Laboratory Battelle Memorial Institute U.S. Navy SPAWAR Systems Center, Pacific Sandia National Laboratories U.S. National Institute of Standards and Technology (NIST) NEMA DICOS Contributors 7

  8. DICOS Project Development • NEMA has standards development expertise, member technical expertise, and DICOM experience • A standards project is born • At the request of DHS, DICOM (medical) was adapted into DICOS (security) • DICOM provided a sound technical basis for DICOS development • Many existing DICOM services and data infrastructure were inherited and leveraged without change

  9. DICOM Patient Subject of Exam = Patient Only About 3 patients per hour/CT device, depending on complexity of exam, with scans ≈ 8 bags DICOM versus DICOS DICOS • Passenger • Subject of Exam = Passenger + checked bags + carry-on • 1,000 bags per hour/CT device

  10. DICOS Project Status – Phase 1 Complete • Published NEMA IIC 1 v01 (DICOS v01) August 2010 • DICOS overview, including roots in DICOM • Addresses data representation for CT, DX, TDR • Security scan site agnostic

  11. NEMA Role – How We Work DICOM experience Facilitate member discussion & decision Teleconferences – Working Groups Meeting times determined by the WG Full Section and Technical Committee Face-to-face Meetings and teleconferences Monthly Status Update to DHS compiled/ distributed by NEMA 11

  12. Challenges • Open standards development arena vs. security-sensitive / classified information • Extensibility • International Implementation • Speed vs Consensus

  13. Additional Steps • Ensure DICOS is developed with extensibility in mind • A standard that can be applied to any potential security scanning environment, including port cargo inspections, customs inspections, border patrol stations • Include the ability to share images and data reports, to include possible “remote screening” applications • Incorporate appropriate data encryption safeguards for shared data • Extend DICOS to support software interoperability that will facilitate rapid update of threat detection algorithms

  14. Additional Steps • Extend DICOS implementations to include border protection and cargo security applications • Integrate security checkpoints to create an “electronic border” capable of seamlessly sharing all data, regardless of source • Formulate a plan to address unique DHS cargo security and border protection needs with DICOS
