Provided is an imaging device including a light source that radiates light in at least two different wavelength bands and an imaging element that acquires signals individually from the light in the two different wavelength bands. The two different wavelength bands include a first wavelength band from 400 to 580 nm for use in dermatoglyphic pattern authentication, and a second wavelength band of 650 nm or more mainly including near-infrared rays for use in vein authentication.

A system provides intelligent gallery management for biometrics. A first gallery is obtained that includes biometric and/or other information on a population of people. An application is identified. A subset of the population of people is identified based on the application. A second gallery is derived from the first gallery by pulling the information for the subset of the population of people without pulling the information for the population of people not in the subset. Biometric identification (such as facial recognition) for the application may then be performed using the second gallery rather than the first gallery. In this way, the system is improved as less time is required for biometric identification, fewer device resources are used, and so on.

A station device in a biometric pre-identification system uses identity to perform one or more actions. Identities are determined (such as via a backend) using biometric information. A biometric pre-identification device obtains biometric information and/or a digital representation thereof from a person approaching the station device. The biometric pre-identification device transmits such to the station device, facilitating the station to begin and/or perform various actions. The station device begins or performs the actions using the identity determined based on the biometric information before the person arrives at the station device.

In authentication using sensor information, both reduction of processing burdens and assurance of security can be achieved.

Provided is an information processing device including an authentication unit configured to authenticate a user on the basis of collected sensor information, and the authentication unit authenticates the user on the basis of a single feature quantity extracted on the basis of sensor information collected by at least two sensors and a single registered feature quantity extracted on the basis of sensor information collected in advance by the at least two sensors.

A plurality of subpixels is included in one pixel. An imaging device includes a subpixel, a pixel, and a pixel array. The subpixel includes a photoelectric conversion element that receives light incident at a predetermined angle and outputs an analog signal on the basis of intensity of the received light. The pixel includes a plurality of the subpixels, a lens that condenses light incident from an outside on the subpixel, and a photoelectric conversion element isolation portion that does not propagate information regarding intensity of the light acquired in the photoelectric conversion element to the adjacent photoelectric conversion element, and further includes a light-shielding wall that shields light incident on the lens of another pixel. The pixel array includes a plurality of the pixels.

A fingerprint module includes: a lens, a crystal, and an optical fingerprint chip, where the crystal is an anisotropic medium, the lens is located on one side of the crystal, the optical fingerprint chip is located on the other side of the crystal, and the optical fingerprint chip is fixed in a substrate of an electronic device. Incident light including fingerprint information is incident to the crystal through the lens and is incident to the optical fingerprint chip after being refracted by the crystal; and the optical fingerprint chip is used for generating a fingerprint image, and the fingerprint image is used for fingerprint recognition.

A method for generating an electronic signature for an electronic document is implemented by an electronic device that is in communication with a stylus pen and a handwriting input device that includes a writing area. The method includes: initiating a signature input procedure associated with the electronic document; obtaining a signature pattern and an experienced pressure dataset recorded by the handwriting input device during the signature input procedure, and obtaining a fingerprint dataset and an applied pressure dataset recorded by the stylus pen during the signature input procedure; determining whether the experienced pressure dataset corresponds with the applied pressure dataset; and in the case where the experienced pressure dataset corresponds with the applied pressure dataset, generating a signed electronic document by presenting the signature pattern on a part of the electronic document and embedding the fingerprint dataset in the signature pattern.
