Body ImagesFacePrior -- Ante-mortem:* Passport, driver license,family photos, etc.* Try to get frontal andfairly recentPost-mortem or for livingamnesiacs:Other Parts, Scars, Tattoos, InjuriesPrior -- Ante-mortem:* As available* Distinctive features (e.g. club foot, extra finger, brokennose, etc.)Post-mortem or for living amnesiacs:* With ruler* All angles•Mark eye locations using 2Dmarkups-- Automated Matching-- Forensic Analysis &Comparison-- Forensic Analysis & Comparison

Image Markups• Forensics: 2D and 3D anthropomorphic facial image markup fields

DNA•Rapid DNA andLaboratoryProcessing•Pedigree tree• Claimed and Validatedrelationships• Data on victim andrelatives in onetransaction• X-STR, Y-STR,Mitochondrial

Conformance Test ToolsBiometric ConformanceTest Software forANSI/NIST-ITL 1-2011(AN-2011) Transactions *• Test assertions based onNIST SP 500-295• CTM for AN-2011• Tests for selected RecordTypes in traditionalencoding:• Installer• Command Line Interface• Under development: toolto test XML encoding* Developed by NIST/ITL Computer Security Division. Sponsored, in part, by DHS/US-VISIT

Dental Working Group• Dental Forensics Working with the AmericanDental Association to base Type-12 record upon their Spec 1058 Meetings held in Argentina,Washington, D.C., New York(with SWG-DVI), Lyon (withINTERPOL), Atlanta (withAAFS), and San Francisco (withADA) FBI has done the update to theANSI/NIST-ITL XML schemafor the current draft Will be presented as a supplementto ANSI/NIST-ITL 1-2011 forvoting

Dental ForensicsDraft available athttp://www.nist.gov/itl/iad/ig/ansi_standard_dental_forensics.cfmBased on ADA Specification 1058Familial Data SetDental History Data SetTooth Data SetMouth Data SetVisual Image Data SetRadiograph Image Data SetIncludes DICOM data & images (Electronic Health Record)

Key Challenges : Dental ForensicsTeeth numbering not the same in US and other nationsDecision: Use ISO standard for transmissionDental Forensic Systems all use different datadefinitions and levels of detailDecision:* Use the ADA Spec 1058 as a ‘translator’* State the level of aggregation for each system(i.e. NamUS, WinID, NCIC, UDIM, Plass & FastID)* Include original encoding with transmission tohelp resolves ambiguities

Pattern InjuryNew Fields added to Type-10Field 10.046: Victim / VICcurrent subject statuslivingbody statusdeceasedunknownClass 1 Natural Tissue (Whole or Fragment)Class 2 Decomposed (Whole or Fragment)Class 3 Skeletal (Whole or Fragment)Field 10.047: Data collection organization / DCO

Pattern InjuryField 10.048: Pattern injury descriptionImage location (using NCIC codes to define body parts)Type of injury (Avulsion, laceration, etc.)Color of injurySurface contourShape and size (measured using 2D ABFO ruler)Tissue characteristicsUnderlying structurePossible cause (human, animal, object, etc.)

Perioral / CheiloscopicRecommend use of Field 10.029: 2Dfacial feature points / FFP to indicatefeatures of the lip print when sendingan image of the lips of the possiblesuspect.Add new code to Table 58 (Type-10image types) as Perioral.Modify Field 10.040 NCIC SMT codeto use the NCIC codes to specifylocation of the lip print on thevictim’s body.Include information about commoncheiloscopic classifications

New Image TypesModify Field 10.012 Color space / CSP to include morepossibilities than currently (grayscale, color andundefined)SonogramRadiograph (X-ray), including CT scansand cone-beamsMagnetic resonance image (MRI)

Palatine DescriptorsProblem: ADA Mouth Data Set does notinclude descriptors for dental arch,rugae ramification or shape.Solution:Initiate a revision to ADAspecification 1058 instead of addingdescriptors to ANSI/NIST-ITL in theSupplement.Impact:Descriptors will not be includedinitially when Dental Supplement isadopted. Expected to take more than ayear.

Forensic VoiceFor investigatory and forensic usesnot intended for applications like access controlIncludes audio recordings, as well as related informationdiarization (when speech occurs during the recording)transcription (what is said)redaction annotation (‘bleeping’ of portions –sometimes required by legal authorities)snipping annotation (cutting out portions of a longer recording)audio characteristics (recording device, CODECs, etc.)geographic location of speakers and recording device(s)speaker characteristics (impairment, language, etc.)Example: Compare a recording of a ransom call in a kidnapping caseagainst known voice samples of suspects

Mobile BiometricsMobile ID Best Practice Recommendation (BPR)* issued in 2009* defined subject acquisition profiles* defined military and law enforcement profiles* requires use of ANSI/NIST-ITL standardANSI/NIST-ITL 1-2011* incorporates key points of the BPRTechnological advancements and modified operationalneeds suggest that a new document is neededKey point: What type?

ANSI/NIST-ITL LITE

Object Oriented DataBullets and CartridgesIssue: Advances in imaging analysis are making new approaches toidentification of weapons or classes of weapons more accurate (i.e. 3Dtopographic data)Need: Databases for matcher system development and initial testing as wellas for sequestered testing (much like is usually done at NIST)Problem: How to receive the data (transmission protocols) and how to makeit accessible

Issue:Disaster Victim Identification Procedures usingANSI/NIST-ITL for data transmissionData to be received from around the worldFingerprints, Facial images, Dental records, DNA samplesData to be collected together relating to a subject and updated as needed (i.e.pedigree trees and established relationships)Medical examiners & disaster recovery teams have not worked with policedepartments to transmit data in ANSI/NIST-ITL formatSolution:Develop a Best Practice Recommendations document

NEW PROPOSAL2013/2014: Prepare interfaces based upon standard• 2014: Demonstration at ADA meeting of a simulateddisaster with to show receiving information from NewYork, overseas, INTERPOL to the conference andentering it into NCIC, NamUs, WinID and checkingresults• focus on dental data exchange• 2015: Data-exchange simulation of a disaster, tocommemorate the 10 th anniversary of Katrina• include capabilities for DNA (including RapidDNA), fingerprints, as well as dental
