ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONTable 56 EFS codes for comparison determinationsCategory Code Description / UsageIndividualization INDIV The two impressions originated from the same source.Inconclusive due toinsufficientinformationInconclusive, butwith correspondingfeatures notedInconclusive, butwith dissimilarfeatures notedInconclusive due tono overlapping areaExclusion of sourceINC_IINC_CINC_DINC_NEX_SRCIndividualization and exclusion are not possible because of insufficientcorresponding or contradictory data. This category should be used if thespecific other types of inconclusive determinations do not apply.No conclusive determination can be made. Corresponding features arepresent, and no substantive contradictory features are present. Thecorrespondence of features is supportive of the conclusion that the twoimpressions originated from the same source, but not to the extentsufficient for individualization.This determination should be made if the examiner determines that theimpressions are almost certainly from the same source, but cannot makean individualization determination. This is sometimes described as aqualified conclusion.No conclusive determination can be made. Non-corresponding featuresare present. The dissimilarity of features is supportive of the conclusionthat the two impressions originated from different sources, but not to theextent sufficient for exclusion.This determination should be made if the examiner determines that theimpressions are almost certainly not from the same source, but cannotmake an exclusion determination. This is sometimes described as aqualified exclusion.Individualization and exclusion are not possible because no correspondingor potentially corresponding areas of friction ridge detail are present.This determination should be made if there is sufficient information in theimpressions to determine that there are no areas in the impressions tocompare, such as when one print is of the left half of a finger and theother is of the right half.The two impressions originated from different sources of friction ridgeskin (e.g. different fingers), but the subject cannot be excluded.Exclusion of subject EX_SUB The two impressions originated from different subjects.No determination NONE No determination has been made. (default)8.9.7.50 Field 9.363: EFS relative rotation of corresponding print / RRCThis optional field may be used when two or more images contained in a single ANSI/NIST-ITL transaction are compared. This field indicates the relative overall rotation necessary forthe prints to be compared. Each subfield consists of 2 information items. The number ofsubfields is limited only by the number of Type-9 records in the transaction.The first information item (rotation IDC reference / RIR) indicates the IDC for theType-9 record associated with the target image/ Type-9 record for a given RRC. See Section7.3.1. See Field 9.360 or Field 9.362 for examples of other IDC references.)The second information item (relative overall rotation / ROR) defines the integernumber of degrees that the target image and/or features referenced by RIR shall be rotatedto correspond to the data in this Type-9 record. Positive numbers indicate degreescounterclockwise; negative numbers indicate degrees clockwise: ( -179 to 180 inclusive).The allowed special character is the negative sign.186
