Part 2 ANSI/NIST-ITL 2-2008
substitutes for the abstract element provided by this standard. These
levels of required details shall be agreed upon between the sender and recipient.
208.1.5 Type-8 Signature image record
The XML name for the Type-8 record is , and its
element shall have a value of “08”. Type-8 logical
records shall contain and be used to exchange scanned high-resolution binary or vectored
signature image data. If scanned, the resolution of the image data shall be no less than the
minimum scanning resolution. If necessary, the scanned image data shall be subsampled,
scaled down, or interpolated to fall within the limits of the transmitting resolution requirement.
The resultant transmitting resolution shall be within the bounds of the permissible transmitting
resolutions for the high-resolution fingerprint images. Vectored signature data shall be expressed
as a series of numeric integers.
Typically, there may be up to two of these Type-8 signature records in a file. Each Type-8 record
shall contain image data representing the signature of the person being fingerprinted or of the
official taking the fingerprint.
208.1.6 Type-9 Minutiae data record
The XML name for the Type-9 record is , and its
element shall have a value of “09”. Type-9 logical records shall
contain and be used to exchange geometric and topological minutiae templates and related
information encoded from a finger or palm. Each record shall represent the processed image
data from which the location and orientation descriptors of extracted minutiae characteristics are
listed. The primary use of this record type shall be for remote searching of latent prints but may
also be used for applications such as physical or logical access control. Each Type-9 logical
record shall contain the minutiae data read from a fingerprint, palm, or latent image.
208.1.7 Type-10 Facial & SMT image record
The XML name for the Type-10 record is , and
its element shall have a value of “10”. Type-10 image
records shall contain and be used to exchange facial and image data from scars, marks, and
tattoos (SMT) together with textual information pertinent to the digitized image. The source of the
image data shall be the image captured from scanning a photograph, a live image captured with a
digital camera, or a digitized “freeze-frame” from a video camera.
208.1.8 Type-11 Reserved for future use
208.1.9 Type-12 Reserved for future use
208.1.10 Type-13 Variable-resolution latent image record
The XML name for the Type-13 record is , and its
element shall have a value of “13”. Type-13 image
records shall contain and be used to exchange variable-resolution latent fingerprint or palmprint
image data together with fixed and user-defined textual information elements pertinent
to the digitized image. In all cases, the minimum scanning resolution (or effective scanning
resolution) and transmission rate for latent images shall be 39.37 ppmm plus or minus 0.40
