Abstract: An electronic apparatus for managing data based on a block chain and a method therefor are provided. The electronic apparatus includes a communication interface, a memory, and a processor to receive a request for accessing data from an authenticated user, generate first block information regarding the request by including information on the request and at least one second block information related to the request from among a plurality of second block information stored in the memory, transmit the generated first block information to at least one of a plurality of external apparatuses constituting a block chain, and update the plurality of second block information stored in the memory based on the generated first block information. The plurality of second block information includes information on a block regarding a latest access history by category among a plurality of blocks included in block chain data shared by the plurality of external apparatuses.

Abstract: A method includes: obtaining a first image of an object including a surface having a non-flat shape; identifying a region corresponding to the surface as a region of interest by applying the first image to a first artificial intelligence model; obtaining data about a three-dimensional (3D) shape type of the object by applying the first image to a second AI model; obtaining a set of values of a 3D parameter related to the object, the surface, or the first camera, based on the region and the data; estimating the non-flat shape of the surface, based on the set of values of the 3D parameter; and obtaining a flat surface image in which the non-flat shape of the surface is flattened, by performing a perspective transformation on the surface.

Abstract: A method of generating a spatial map includes obtaining a captured image of a target area in a space, obtaining light detection and ranging (LiDAR) scan data by scanning a depth of the target area with respect to a first height, performing object detection on the captured image, and, according to the performed object detection, generating a spatial map of the target area, based on all of the LiDAR scan data and the captured image.

Abstract: A method and apparatus for executing an application are provided. The method of executing an application may include: measuring internal air pressure in an electronic device by using a barometer; receiving a user input of applying a force to an external surface of the electronic device by using the barometer, and detecting a value of variation of the internal air pressure, the variation occurring due to the force; and performing a preset operation of the electronic device based on the detected value of the variation of the internal air pressure.
