Provided is an authentication system that improves user convenience. This authentication system includes at least one first terminal, a plurality of second terminals, and a server device. The first terminal is capable of providing services using a biometric authentication function or non-biometric authentication function. Each of the second terminals is capable of switching between a biometric authentication function and a non-biometric authentication function and capable of providing services using the biometric authentication function or non-biometric authentication function. The server device is connected to the first terminal and the plurality of second terminals. The server device calculates the rate of usage of a biometric authentication function by the at least one first terminal. The server device determines an operation mode for at least one of the plurality of second terminals on the basis of the calculated rate of usage.

This fingerprint registration method by a user terminal device includes: capturing an image of a fingertip by a camera provided to the user terminal device; generating and displaying an enlarged image obtained by enlarging a fingertip image that includes the captured fingertip; receiving a user operation whether or not the fingertip image is to be registered for fingerprint authentication on the basis of the enlarged image; and transmitting, to an external server as fingerprint data, the fingertip image on which registration operation has been performed through the user operation.

The disclosure accurately authenticates a subject, regardless of which audio device is used for the in-ear acoustic authentication. A feature extraction unit (11) applies a test signal to an ear of a subject using an audio device, and upon receiving an acoustic signal from the subject, extracts, from the acoustic signal, a first feature relating to the system consisting of the audio device and the ear of the subject; a correction unit (12) corrects the first feature to a second feature that would result if a prescribed reference device were used instead of the audio device; and an authentication unit (13) authenticates the subject by comparing the second feature with a feature indicated by pre-registered authentication information.

Devices, systems, and methods for storing and managing sensitive information in a connected environment are provided. The system comprises a master controller and a sensitive information storage device (“SIS device”). The SIS device has an island that can be activated by user interaction with the SIS device. In general, the island is deactivated by default and when the island is deactivated, sensitive information that is stored on the SIS device cannot be accessed. Only when the island is activated by user interaction can the stored sensitive information be accessed.

Disclosed are various approaches for performing biometric authentication of users using an application running on a client device. A biometric model can be trained using biometric data from a population of users. The biometric model can be used by the client application to authenticate users and can be separate from system-level biometric authentication capabilities of the client device.

An electronic device is provided. The electronic device includes a communication circuit, a display, a memory including a first display driver, a processor functionally connected with the communication circuit, the display, and the memory, and a secure module which is physically separated from the processor, and includes a secure processor and a second display driver, and the secure processor is configured to: when secure data is received from an external server through the communication circuit, disable the first display driver and enable the second display driver, and output a user interface including a first object corresponding to the secure data to the display by using the enabled second display driver.

Corporate information technology (IT) networks can protect sensitive data sent to computers located outside of the corporate IT network. For example, a computer located outside of the corporate IT network may receive a message that instructs the computer to operate in a data protection mode in which the computer reduces a frame rate of a monitor of the computer from a first frame rate to a lower second frame rate. In this example, the computer receives sensitive information that includes sensitive visual content to be displayed on the monitor and displays the sensitive visual content on the monitor configured to operate at the second frame rate.
