Video fingerprinting or video hashing are a class of dimension reduction techniques [1] in which a system identifies, extracts and then summarizes characteristic components of a video as a unique or a set of multiple perceptual hashes or fingerprints, enabling that video to be uniquely identified. This technology has proven to be effective at ...
As with fingerprints, an individual's DNA profile and characteristics are unique. [citation needed] Forensic identification using DNA can be useful in different cases such as determining suspects in violent crimes, solving paternity/maternity, and identifying human remains of victims from mass disasters or missing person cases. [21]
Perceptual hashing is the use of a fingerprinting algorithm that produces a snippet, hash, or fingerprint of various forms of multimedia. [ 1 ] [ 2 ] A perceptual hash is a type of locality-sensitive hash , which is analogous if features of the multimedia are similar.
Similarly to the use of fingerprint powder in fingerprint analysis, fingerprint powder is used when there is a latent footprint that is composed of mostly oils, instead of dust or dirt. The use of fingerprint powder allows the analyst to more easily find the print and identify the characteristics of the print. [2]
The FBI then catalogs the fingerprints along with any criminal history linked with the subject. Law enforcement agencies can then request a search in IAFIS to identify crime scene (latent) fingerprints obtained during criminal investigations. Civil searches are also performed, but the FBI charges a fee and the response time is slower.
The project's goal is to expand the capabilities of the Integrated Automated Fingerprint Identification System (IAFIS), which is currently used by law enforcement to identify subjects by their fingerprints and to look up their criminal history. The NGI system will be a more modular system (allowing easy expandability).

Magnetic resonance fingerprinting (MRF) is methodology in quantitative magnetic resonance imaging (MRI) characterized by a pseudo-randomized acquisition strategy. It involves creating unique signal patterns or 'fingerprints' for different materials or tissues after which a pattern recognition algorithm matches these fingerprints with a predefined dictionary of expected signal patterns.
