The measure of the fingerprint image quality is in dots per inch (DPI). [8] Optical scanners take a visual image of the fingerprint using a digital camera. Capacitive or CMOS scanners use capacitors and thus electric current to form an image of the fingerprint. This type of scanner tends to excel in terms of precision.
Automated fingerprint verification is a closely related technique used in applications such as attendance and access control systems. On a technical level, verification systems verify a claimed identity (a user might claim to be John by presenting his PIN or ID card and verify his identity using his fingerprint), whereas identification systems ...

Others have tried to reduce the size of the fingerprint by only looking around shot changes. [5] Video fingerprinting does not rely on any addition to the video stream. A video fingerprint cannot be removed, because it is not added. In addition, a reference video fingerprint can be created at any point, from any copy of the video. [6] [7]
As of 2016, facial recognition was being used to identify people in photos taken by police in San Diego and Los Angeles (not on real-time video, and only against booking photos) [94] and use was planned in West Virginia and Dallas. [95] In recent years Maryland has used face recognition by comparing people's faces to their driver's license photos.
