Provided are an apparatus and method for verifying the integrity of a video file. The method includes receiving a video file and model information of a video recording device which is claimed to have recorded a verification-target video, extracting a header structure and a header value of the video file, extracting characteristic information according to the received model information of the video recording device from a characteristic database, and determining whether the extracted characteristic information according to the model information of the video recording device corresponds to the header structure and the header value of the video file.

Apparatus and method for verifying the integrity of video file

A device for integrity verification of image data. The device comprises: a database configured to store multiple field signatures respectively corresponding to multiple editing tools; a memory configured to store a program for integrity verification of image data; and a processor configured to execute the program stored in the memory. The processor: extracts a field from the image data when the program is executed; determines whether or not there is a field signature matched with the extracted field from among the multiple field signatures; and determines whether or not the image data are edited depending on a result of the determination.
