Claims8
An electronic device comprising:
- a display portion comprising a plurality of light-emitting devices and a plurality of light-receiving devices,
- wherein the plurality of light-emitting devices and the plurality of light-receiving devices are placed close to each other,
- wherein the display portion displays a keyboard key with the plurality of light-emitting devices,
- wherein a first character string is input by first touch operation on the keyboard key with a finger,
- wherein an image of a fingerprint of the finger used for the first touch operation is captured by the plurality of light-receiving devices provided close to the plurality of light-emitting devices displaying the keyboard key used when the first character string is input, and
- wherein information of the first character string and information of the fingerprint of the finger used for the first touch operation are compared with registered information to perform authentication.
A method for authentication of an electronic device performing touch operation and fingerprint image capturing on a display portion,
- wherein a keyboard key is displayed on the display portion,
- wherein a first character string is input by first touch operation with a finger, to the keyboard key,
- wherein an image of a fingerprint of the finger inputting the first character string is captured when the first touch operation is performed, and
- wherein whether or not the first character string matches registered information and whether or not information of the fingerprint of the finger inputting the first character string matches the registered information are checked.
