===Attacks at presentation===
In the context of biometric systems, presentation attacks may also be called "[[spoofing attack]]s".

As per the recent ISO/IEC 30107 standard,<ref>{{Cite web|url=http://www.iso.org/cms/render/live/en/sites/isoorg/contents/data/standard/05/32/53227.html|title=ISO/IEC 30107-1:2016|website=iso.org|language=en|access-date=2019-04-23}}</ref> presentation attacks are defined as "presentation to the biometric capture subsystem with the goal of interfering with the operation of the biometric system". These attacks can be either impersonation or [[obfuscation]] attacks. Impersonation attacks try to gain access by pretending to be someone else. Obfuscation attacks may, for example, try to evade [[face detection]] and [[Facial recognition system|face recognition]] systems.

Several methods have been proposed to counteract presentation attacks.<ref>{{Cite journal|date=2014|editor-last=Marcel|editor-first=Sébastien|editor2-last=Nixon|editor2-first=Mark S.|editor3-last=Li|editor3-first=Stan Z.|title=Handbook of Biometric Anti-Spoofing|journal=Advances in Computer Vision and Pattern Recognition|doi=10.1007/978-1-4471-6524-8|issn=2191-6586|isbn=978-1-4471-6523-1|s2cid=27594864}}</ref>
