This Recommendation defines the requirements of guideline to provide security countermeasures for the telebiometrics protection procedures. This Recommendation defines the vulnerabilities and threats in operating telebiometric systems, and proposes a general guideline for security countermeasures from both technical and managerial perspectives in order to establish a safe environment for the use of telebiometric systems and to protect individual privacy. This Recommendation describes countermeasures that allow the protection of biometric devices as related to their installation, removal, and delivery. Countermeasures are proposed for the protection of biometric systems as related to their operational procedures, as well as the roles and responsibilities of personnel involved in system design. It is expected that the proposed countermeasures will ensure security and reliability of the flow of biometric information in a telecommunications environment.
