ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic InformationFigure 8: Palm and finger segment positions. 20If the physical position for the image cannot be determined, the following fieldsshall be used (see Table 9):If the image is from a finger (including the lower joints) but the finger positionis unknown, the code “0” (Unknown fingerprint) shall be used.If the image is from a palm but the location cannot be determined, the code“20” (Unknown palm) shall be used.If the type of friction skin is unknown, each of the possible positions shall beincluded as separate data entries. Codes “0” (Unknown fingerprint) and “20”(Unknown palm) together address all friction ridge areas on the hands; codes“37” (Unknown sole of foot) and “40” (Unknown toe) together address allfriction ridge areas on the feet.If the image/region of interest contains multiple areas, this field allows the optionto label and mark each of those areas within the region of interest. Each of theareas present shall be indicated using the appropriate Position Code/Finger20Note that the interdigital and hypothenar areas overlap at the base of the little finger70DRAFT 2
