An apparatus for reading an image executes operations including receiving a plurality of images for a same subject from a photographing device, obtaining a screen division value related to the plurality of images, checking focused sections of the plurality of images based on the obtained screen division value, and determining type of the plurality of images based on a result of checking the focused sections. According to the apparatus, it can be determined whether an image is actually photographed without a separate ToF module.

Method for photographing and reading an image, and apparatus therefor

A method for photographing an image performed by a computer device according to an embodiment of the present application includes obtaining a screen division value for photographing an image, classifying a photographing screen into a plurality of sections based on the screen division value, photographing a first image by focusing a first section among the plurality of sections, photographing a second image by focusing a second section among the plurality of sections and transmitting the first image and the second image to a server. According to the method, it is capable of reading whether an image is actually photographed without having a separate ToF module, and applicable to an outdoor environment on which interference from other light rays is strong.

A method for preventing forgery of data according to an embodiment includes determining a noise level based on metadata of original data, generating noise by applying the determined noise level to a preset noise pattern, generating transformed data of the original data by adding the generated noise to the original data, and transmitting the transformed data and the metadata to a server.
