Palm Print RecognitionA biometric modality that uses the physical structure of an individual's palm print for recognition purposes, as illustrated below.
PerformanceThose operational and support characteristics of the system that allow it to effectively and efficiently perform its assigned mission over time.
PIN (Personal Identification Number)A security method used to show "what you know." Depending on the system, a PIN could be used to either claim or verify a claimed identity.
Pixels Per Inch (PPI)A measure of the resolution of a digital image. The higher the PPI, the more information is included in the image, and the larger the file size.
Populationthe totality of items or units of material under consideration.
ProbeA sequence of DNA or RNA, labeled or marked with a radioactive isotope, used to detect the presence of complementary nucleotide sequences. See Nucleotide.
Receiver Operating Characteristics (ROC)A method of showing measured accuracy performance of a biometric system. A verification ROC compares false accept rate vs. verification rate.
RecognitionA generic term used in the description of biometric systems (e.g. face recognition or iris recognition) relating to their fundamental function.
recordAll the documents and evidence plus transcripts of oral proceedings in a case.
referenceA document that discloses subject matter that is material to a determination of the patentability of a claimed invention. MPEP 2126, MPEP 2126.
Ridge EndingA minutiae point at the ending of a friction ridge, as illustrated below. See also bifurcation, friction ridge.
Rolled FingerprintsAn image that includes fingerprint data from nail to nail, obtained by �rolling� the finger across a sensor, as illustrated below.

Similarity ScoreA value returned by a biometric algorithm that indicates the degree of similarity or correlation between a biometric sample and a reference.
SkimmingThe act of obtaining data from an unknowing end user who is not willingly submitting the sample at that time.
Slap FingerprintFingerprints taken by simultaneously pressing the four fingers of one hand onto a scanner or a fingerprint card, as illustrated below.

Speaker Recognition EvaluationsAn ongoing series of evaluations of speaker recognition systems. For more information, visit www.nist.gov/speech/tests/spk/index.htm.
Speech RecognitionA technology that enables a machine to recognize spoken words. Speech recognition is not a biometric technology.
SpoofingSome market analysts maintain that the increased volatility in stock markets may be the result of an illegal practice known as spoofing, or phantom bids.
Submissionany single delivery of evidence in a specific investigation.
Technology EvaluationOne of the three types of performance evaluations. The primary goal of a technology evaluation is to measure performance of biometric systems, typically…

ThreatRelated to Aggro. This is what a character "gives off" to generate or draw monster aggro.
Thresholdthe point a system must cross to enter a new state or condition.
Throughput RateThe number of biometric transactions that a biometric system processes within a stated time interval.
VerificationTo confirm the truth or correctness of something. Vitreous humor – The ocular fluid (from within the eye) that is often used as a sample for testing in…
Verification RateA statistic used to measure biometric performance when operating in the verification task. The rate at which legitimate end-users are correctly verified.
VulnerabilityWeakness in an information system, system security procedures, internal controls, or implementation that could be exploited or triggered by a threat…
WatchlistA term sometimes referred to as open-set identification that describes one of the three tasks that biometric systems perform.
Wavelet Scalar Quantization (WSQ)An FBI-specified compression standard algorithm that is used for the exchange of fingerprints within the criminal justice community.
WhorlA fingerprint pattern in which the ridges are circular or nearly circular.... The pattern will contain 2 or more detals.
