FIELD: physics, computer engineering.
SUBSTANCE: invention relates to image forming apparatus with an identity authentication function. Disclosed is an image forming apparatus which includes an image forming unit. The apparatus also includes a recording unit, configured to record a plurality of data on characteristic features, up to the maximum limit, in non-volatile memory with reference to the same object. The apparatus also includes an authentication unit, configured to identify whether an object detected based on an image captured by the image forming unit is a recorded object based on data on characteristic features recorded in the nonvolatile memory. Furthermore, the apparatus includes a selection unit, configured to select one of the objects recorded in the nonvolatile memory, for which new data on characteristic features were recorded through the recording unit.
EFFECT: high accuracy of authenticating an object by selecting new data on characteristic features.
