To serve its intended purposes, a fingerprinting algorithm must be able to capture the identity of a file with virtual certainty. In other words, the probability of a collision — two files yielding the same fingerprint — must be negligible, compared to the probability of other unavoidable causes of fatal errors (such as the system being destroyed by war or by a meteorite): say, 10 −20 or ...
Scanning forms ("fingerprint cards") with a forensic AFIS complies with standards established by the FBI and National Institute of Standards and Technology (NIST). To match a print, a fingerprint technician scans in the print in question, and computer algorithms are utilized to mark all minutia points, cores, and deltas detected on the print ...
Automated fingerprint identification is the process of using a computer to match fingerprints against a database of known and unknown prints in the fingerprint identification system. Automated fingerprint identification systems (AFIS) are primarily used by law enforcement agencies for criminal identification purposes, the most important of ...

Many implementations of the Rabin–Karp algorithm internally use Rabin fingerprints. The Low Bandwidth Network Filesystem (LBFS) from MIT uses Rabin fingerprints to implement variable size shift-resistant blocks. [2] The basic idea is that the filesystem computes the cryptographic hash of each block in a file. To save on transfers between the ...
Perceptual hashing is the use of a fingerprinting algorithm that produces a snippet, hash, or fingerprint of various forms of multimedia. [ 22 ] [ 23 ] A perceptual hash is a type of locality-sensitive hash , which is analogous if features of the multimedia are similar.
The Wavelet Scalar Quantization algorithm (WSQ) is a compression algorithm used for gray-scale fingerprint images. It is based on wavelet theory and has become a standard for the exchange and storage of fingerprint images.
The Fingerprint Verification Competition (FVC) is an international competition for fingerprint verification algorithms organized in 2000 by the Biometric System Laboratory (University of Bologna), the U.S. National Biometric Test Center (San Jose State University) and the Pattern Recognition and Image Processing Laboratory (Michigan State University).
