Image recognition is a process in which a captured image, typically an image of a biometric attribute of an individual, is matched against the copy of the image that is stored in the database of recognition system. In order to perform image recognition process, the biometric identification oriented organ (such as iris, palm vein, etc.) of an individual is scanned through the sensor, which captures the current image of the organ. The captured image is then matched against the image stored in the database for identification and authentication.
Image recognition process involves two steps. In the first step, an image of any biometric attribute is enrolled with the database of the biometric identification system (as discussed above). The second step of image recognition process is when the image is matched against the copy of the image stored in the database. In case the current image of the biometric attribute fails to match, access to the sensitive information for that particular individual is denied whatsoever. This means, that an image recognition system provides complete security to the classified data.
