ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONThe Type-16 image record is designed for developmental purposes and for the exchange ofmiscellaneous images. This record shall contain and be used to exchange image datatogether with textual information fields pertinent to the digitized image. Such an image isusually not elsewhere specified or described in this standard. With the exception of thefields at the start of the record and the descriptors for the image data, the remaining detailsof the Type-16 record are undefined by this standard and shall be agreed upon between thesender and recipient.5.3.17 Type-17 recordsType-17 image records shall contain iris image data. This record type was developed toprovide a basic level of interoperability and harmonization with the ANSI INCITS 379-2004Iris image interchange format and the ISO/IEC 19794-6 Iris image data interchange format.It also contains optional descriptive data fields and (new to the 2011 of the standard) imagemarkup fields. Generic iris images may be exchanged using the mandatory fields of thisrecord type. Field 17.018 (Global unique identifier) from the 2007 and 2008 version ofthe standard has been deprecated in this version.5.3.18 Type-18 recordsThe Type-18 record (new to the 2011 of the standard) shall contain and be used to exchangeDNA and related data. It was developed to provide a basic level of interoperability with thedraft format of the ISO/IEC 19794-14 DNA data interchange format.With full consideration to privacy, this standard only uses the non-coding regions of DNA.The regions of the DNA that encode phenotypic information are deliberately avoided.5.3.19 Type-19 recordsType-19 image records (new to the 2011 version of the standard) shall contain and be usedto exchange variable-resolution plantar print image data together with fixed and userdefinedtextual information fields pertinent to the digitized image. While the Type-19record may be used for the exchange of 19.69 ppmm (500 ppi) images, it is stronglyrecommended that the class resolution for plantar images be 39.37 ppmm (1000 ppi). Itshould be noted that as the resolution is increased, more detailed ridge and structureinformation becomes available in the image. However, in all cases the scanning resolutionused to capture a plantar image shall be at least as great as the minimum scanning resolutionof 19.69 ppmm (500 ppi). The variable-resolution plantar image data contained in theType-19 record may be in a compressed form.5.3.20 Type-20 recordsThe Type-20 record (new to the 2011 versio of the standard) shall contain the sourcerepresentation(s) from which other Record Types were derived. Typically, one Type-20source representation is used to generate one or more representations for use in other recordtypes. When a source representation (in a Type-20 record) is processed and the derivedrepresentation is to be used as the source for further derivations, then the derivedrepresentation is contained in a Type-20 record.May, 2013 DRAFT VERSION UPDATE 2013 Page 39

ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONIn some cases, several Type-20 records may be processed to derive a single Type-20record.. Some possible uses of the Type-20 record are shown here.• From a group photo stored in a Type-20 record, a subject’s face is segmented andstored in a Type-10 record.• From a high-resolution color image in a Type-20 record, two latent fingerprintimages are segmented, rescaled and gray-scaled for separate Type-13 records.• From a series of off-angle face images stored in separate Type-20 records, a single2D face image is generated (using fusion) that is stored in a Type-10 record.5.3.21 Type-21 recordsThe Type-21 record shall contain an associated context image, audio / visual recording orother related data. This record type does NOT contain information used to derive biometricinformation contained in other records. Record Type-20 serves that function. RecordType-21 may be used to convey contextual information, such as an image of the area wherelatent fingerprints were captured.[2013d>] Record Type-21 may be used to transmit images (including x-rays) and otherexamination data (such as spectroscopic examinations) on non-human objects or animals.(Such information may be helpful in the analysis of wounds on an unknown deceased thatmay have been caused by scavaging by wild animals). The user should take full advantageof Field 21.020 Comment / COM to enter text descriptions of the images or objectsdescribed in a Type-21 record. [] The Type-22 record is designed to transmit imagery other than standardvisible-wavelength 2D photographic images – including images such as CT scans, andradiographs. These images may be very useful in Disaster Victim Identification andidentification of Unknown Deceased or living persons unable to identify themselves.Ultraviolet and infrared images can also be transmitted using this record type. Thisrecord type may also be used to transmit electronic medical records, such as thosestored in conformance with the DICOM standard. The format of the data is specified inthe record. [
