Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). Scope This part of ISO/IEC 30107 establishes terms and definitions that are useful in the specification, characterization and evaluation of presentation attack detection methods. Outside the scope are standardization of specific PAD detection methods; detailed information about countermeasures (i.e. anti-spoofing techniques), algorithms, or sensors; and overall system-level security or vulnerability assessment. The attacks to be considered in ISO/IEC 30107 are those that take place at the sensor during the presentation and collection of the biometric characteristics. Any other attacks are considered outside the scope of ISO/IEC 30107.
