olemus
ISO/IEC 19794:
lõpliku arvu sammudega käsujada, mis
ütleb biomeetriasüsteemile, kuidas
lahendada mingit probleemi,
enamasti otsustamiseks, kas
biomeetriline proov ja biomeetriline etalon
ühtuvad
= sequence of instructions that tell a biometric system how to solve a particular problem
Note. A biometric algorithm will have a finite number of steps and is typically used by the biometric system software to decide whether biometric probe data and a biometric reference match.

ISO/IEC 2382-37:
kogum käske ja reegleid
biomeetriliste proovide töötluseks;
biomeetriasignaalide ja -andmete täielik töötlus
võib sisaldada signaali tuvastust, segmentimist, biomeetriliste erisuste ekstraktimist, kvaliteedi hindamist, biomeetrilise mudeli genereerimist, biomeetrilise malli genereerimist, võrdlust,
biomeetrilist võrdlusotsustust,
tihendust, hõrendust jm
=
set of instructions and rules for processing biometric samples Note .The complete processing of biometric signals and data may involve: signal detection, segmentation, biometric feature extraction, quality assessment, biometric model generation, biometric template generation, comparison, biometric comparison decision, compression, decompression, etc.
