GB/T 40694.5-2022 Information technology—Pictograms,icons and symbols for use with biometric systems—Part 5:Face applications

Scope

The GB/T 40694 series of standards focuses on the interaction between data collection entities. This document includes a series of diagrams,icons, and symbols to help the public understand the concept and process of using electronic systems to collect and/or evaluate face images. Operators can use this document, as well as other symbols and information. The design of the series of diagrams, icons, and symbols can be used for: -- Identifying the type of biometric recognition sensors; -- Providing supporting explanations related to face image collection. To provide this function, the series of diagrams, icons, and symbols includes directional diagrams, icons, and symbols, as well as action or feedback-based diagrams, icons, and symbols. These face image diagrams, icons, and symbols include: -- Face image collection; -- Single person; -- No headgear; -- No sunglasses; -- Natural expression; -- Hair swept back; -- Visual direction. Although the diagrams, icons, and symbols are displayed separately, they are intended to be combined to fully illustrate the interaction of face image collection. For example, in customs or immigration environments, a procedure composed of individual diagrams, icons, and symbols can be represented as: -- A series of posters while waiting to use the biometric recognition system; -- A series of dynamic screens at the biometric recognition workstation; -- Animated videos or a series of dynamic screens for passengers to watch while queuing; -- Explanatory leaflets for passengers to read while queuing.
