ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONup to 99 segments listed in Field 21.016, but only the relevant segment is contained inField xx.995.Figure 2: Associated Context IndicesRECORD TYPE-21DATA RECORD WITH THE APPROPRIATESOURCE REPRESENTATIONField xx.995 / ASCSubfield k (there can be multiplesource representations)information item ACN value = a ← Field 21.021 / ACN value = ainformation item ASP value = z ← Field 21.016 / SEGSubfield j(for the proper segment)information item ASP value = z7.3.4 Type-10 referenceThere may be several Type-10 images of a particular part of the body. For instance, aphotograph of a tattoo may cover the entire tattoo. Another may be a zoom-in shot of aportion of the tattoo. In order to link these two images, the same index number is assignedto Field 10.039: Type-10 reference number / T10, which is new to the 2011 version of thestandard. Note that these images would have different IDC values.7.3.5 Simultaneous captureIn order to accommodate the emergence of technology that can simultaneously capturefingerprint images on separate platens or other technology that does not preserve the fullrelative position of the fingers to each other, Field 14.026: Simultaneous capture / SCFallows the user to specify the same reference number for all images that weresimultaneously captured. With this field included in a record, the transmitter states thatsequencing errors definitely did not occur on the finger images. Field 14.026 is new to the2011 version of the standard. Multi-finger images generated within a single device basedupon adjacent platens are considered a single capture and thus are not marked assimultaneous capture in this field.7.4 Data Processing LogsThe 2011 version of the standard introduced several capabilities to record operationsperformed to process the biometric sample.7.4.1 Annotation information / ANNNew for the 2011 version of the standard, optional field xx.902 is used to store annotation,May, 2013 DRAFT VERSION UPDATE 2013 Page 51
