Information technology. Security techniques. Security evaluation of biometrics. | Status: Superseded, Withdrawn

1 Scope This International Standard specifies the subjects to be addressed during a security evaluation of a biometric system. It covers the biometric-specific aspects and principles to be considered during the security evaluation of a biometric system. It does not address the non-biometric aspects which might form part of the overall security evaluation of a system using biometric technology (e.g. requirements on databases or communication channels). This International Standard does not aim to define any concrete methodology for the security evaluation of biometric systems but instead focuses on the principal requirements. As such, the requirements in this International Standard are independent of any evaluation or certification scheme and will need to be incorporated into and adapted before being used in the context of a concrete scheme. This International Standard defines various areas that are important to be considered during a security evaluation of a biometric system. These areas are represented by the following clauses of this International Standard:

• — Clauses 4 and 5 of this International Standard give an overview of all terms, definitions and acronyms used,
• — Clause 6 introduces the overall concept for a security evaluation of a biometric system,
• — Clause 7 describes statistical aspects of security-relevant error rates,
• — Clause 8 deals with the vulnerability assessment of biometric systems and
• — Clause 9 describes the evaluation of privacy aspects.

This International Standard is relevant to both evaluator and developer communities.

• — It specifies requirements for evaluators and provides guidance on performing a security evaluation of a biometric system.
• — It serves to inform developers of the requirements for biometric security evaluations to help them prepare for security evaluations.

Although this International Standard is independent of any specific evaluation scheme it could serve as a framework for the development of concrete evaluation and testing methodologies to integrate the requirements for biometric evaluations into existing evaluation and certification schemes. This International Standard refers to and utilizes other biometric standards, notably those for biometric performance testing and reporting from ISO/JTC1 SC 37. These standards have been adapted as necessary for the specific requirements of biometric security evaluation.
