Symbol Representing Biometrics in Use



Yee-Yin Choong, Mary Theofanos, Brian Stanton


During the InterNational Committee for Information Technology Standards (INCITS) M1 task group meetings in 2008, it was recognized that there is a need for a symbol to represent that any biometrics (fingerprint, iris, photo, etc.) are in use. The symbol is to be used to indicate that biometric collection may be in use, for example, to indicate to the public that their photo may be taken or their fingerprints may be scanned. The symbol should be independent of any specific biometric collection processes. It will also need to be generic such that it is applicable to all of the modalities including iris, face, fingerprint, voice, vein, and temperature and any modalities that may be developed in the future. This document describes the development and usability testing of a symbol representing biometrics in use.
