An authentication system for an electronic device with a high security level is provided. The authentication system includes a data retention means that accumulates first data related to a state of the electronic device being used by a first user registered in advance and generates a first data group, a first authentication means that authenticates a second user operating the electronic device as the first user and releases a locked state, a data acquisition means that acquires second data related to a state of the electronic device being used by the second user in a state where the locked state is released, and a second authentication means that authenticates the second user as the first user on the basis of the first data group and the second data and sets the electronic device to the locked state when the second user is not authenticated. The data retention means has a function of deleting the oldest first data of the plurality of pieces of the first data included in the first data group.

Authentication system for electronic device

An image retrieval system with high retrieval accuracy is provided. The image retrieval system includes a database and a processing portion. The database has a function of storing a plurality of pieces of database image data, and a database tag is linked to each of the plurality of pieces of database image data. The processing portion has a function of obtaining database image feature value data representing a feature value of the database image data for each piece of the database image data. The processing portion has a function of obtaining query image feature value data representing a feature value of the query image data. The processing portion has a function of calculating first similarity of the database image data to the query image data for each piece of the database image data. The processing portion has a function of obtaining a query tag linked to the query image data using some of the database tags.

Image retrieval system and image retrieval method

A display position of an image is moved in accordance with positional information of a display device having a curved display surface. Displacement of a display device is sensed by a camera portion and an acceleration sensor, and the display position is determined in accordance with the displacement, so that the image is displayed in the display position. In the case where the display device rotates and the like, a desired piece of information can be displayed automatically in a display region that can be easily seen.

Display device, driving method of display device, program, and memory medium

A novel information processor that can be easily operated is provided. In addition, a novel information processor that is less likely to be operated incorrectly is provided. The conceived information processor includes an arithmetic device including an arithmetic unit and a storage unit that stores a program to be executed by the arithmetic unit and an input/output device including an input unit that can supply an operation instruction and a bend sensor that can supply bend data. The program makes the arithmetic device execute different types of processing in accordance with the combination of the supplied operation instruction and bend data.

Information processor

Information processor for processing and displaying image data on a bendable display unit

A novel data processor which can display a plurality of images arranged in a predetermined order, a novel method for displaying data, or a novel program is provided. The data processor includes an input/output unit which supplies operation instructions, an arithmetic unit which determines data marked as a starting point according to the operation instructions to generate image data, and a display portion which displays the image data.
