ANSI/NIST-ITL 1-2011Data Format for the Interchange of Biometric and Forensic Informationintensity values or a compressed format of the raw data. 12 The polar imageformat is still deprecated, as it was in the earlier versions of this standard.7.13 Type-18 DNA data recordThis record includes the capability to encode DNA dataThe Type-18 record shall contain and be used to exchange DNA data. It wasdeveloped to provide a level of interoperability with the draft format of theISO/IEC 19794-14 DNA data interchange format. Generic DNA data may beexchanged using the mandatory elements of this record type. Optional elementsmay also be used to exchange additional information.7.14 Type-19 Plantar image recordType-19 image records shall contain and be used to exchange variableresolutionplantar print image data together with fixed and user-definedtextual information fields pertinent to the digitized image.The scanning resolution is not specified for this record type. While the Type-19record may be used for the exchange of 19.69 ppmm (500 ppi) images, it isstrongly recommended that the minimum scanning resolution (or effectivescanning resolution) for plantar images be 39.37 ppmm plus or minus 0.40 ppmm(1000 ppi plus or minus 10 ppi). It should be noted that as the resolution isincreased, more detailed ridge and structure information becomes available inthe image. However, in all cases the scanning resolution used to capture aplantar image shall be at least as great as the minimum scanning resolution of19.69 ppmm (500 ppi).The variable-resolution plantar image data contained in the Type-19 record maybe in a compressed form.7.15 Type-20 Original image recordType-20 image records shall contain original images used to transmit an imagethat was prepared for submission in other Record Types. Several Record-20instances may each contain an input used to generate the final image. Thisrecord type also includes logs of the type of data handling done in preparing theimages transmitted in other record Types.Brad Wing 6/19/10 5:07 PMComment: Moving of reference to IREX to afootnote as opposed to main body of the text.Brad Wing 6/19/10 5:07 PMComment: New description for Type 18 record.Brad Wing 6/19/10 5:07 PMComment: This section is re-written7.15.1 Type-20 Original image record value (OIV)The OIR is specified for each original image (Type-20) record It contains twosubfields. The first subfield contains the reference code / OIR for a particularRecord Type-20. This is mandatory for each OIV. The second subfield isoptional. It specifies the reference to the segmentation coordinates of the12•. As an update to the 2007 and 2008 version of the standard, this record also includes compact imageformats shown to be efficient and reliable under the IREX study conducted by NIST.20DRAFT 2
