Biometric Data Fusion
Biometric Maturity
Considerations
Maturity of biometric products (esp. multimodal) Next Generation Identification (NGI) Impact of transnational organised crime Convergence of biometrics and forensic science Application of multi-media data fusion techniques on
biometrics and forensic science Improved capabilities through advancements in
information and communications technology (Cloud computing & quantum computing)
Proliferation of mobile devices “Enter once, search many” operation
PolicingInvestigative Activity
What is an investigation?“an investigation is a search for the truth, in the interests of justice
and in accordance with the specifications of the law”
What does an investigator need to establish1. Has a crime been committed
2. Identity of the offender(s)
3. Location of the offender(s)
4. Connection between the offender and the offence
Crime Scene
Primary Secondary Locard’s principle of exchange, ‘every contact
leaves its trace’ Evidence located
Searchable Identifiable Probative weight Intelligence value

Linking Biometrics and Forensic Science
Bioinformatics
National DNA databases for plants, animals, birds, and insects
Geo-referenced templates may help to locate unique geographical areas
Help in the management of animal/plant disease and bio-containment strategies
Identify stolen animals and stock Identify owners in animal welfare investigation Identify owners of animals in criminal investigations and
local enforcement (animal hair at crime scenes, dog attacks and fecial deposits in public spaces)
Commodity - Drugs
Organic drugs - DNA analysis
Synthetic drugs chemical composition
Pattern recognition of images on packaging
Automated extraction and matching of pill press impressions/features
Commodity – Tool Marks
Tool mark examination and firearm/ballistic examination
Develop templates for common articles (eg. shoe impressions)
Reactive or Proactive Capture and storage of
images of known and recovered firearms
The future
Forensic multi-media data fusion and information retrieval platform Consideration of evidence in the context of all other
evidence Open architecture to support interoperability Integrated/networked computerised system(s) Facilitate high volumes of transactions and fast turn
around Processing scalability and matcher performance
scalability
