Abstract: An apparatus for generating an encrypted moving picture file of an ISO(International Organization for Standardization) base media file format, an apparatus for recovering an encrypted moving picture, and a recovery method therefor are provided to protect contents from illegal copy in streaming or download service environment by allowing a server to apply encryption and decryption technique, encrypt moving picture contents of the ISO base media file format, and service the encrypted moving picture contents, and allowing a client to decrypt the encrypted moving picture in real time. An ISO base media file analyzing unit(12) receives an original moving picture file of an ISO base media file format, analyzes box information describing information about a media stream in an ISO base media file structure, and extracts positions of video and audio samples and a position of a hint sample of a hint track. A sample encrypting unit(13) confirms video and audio frame headers from video/audio sample position information extracted in the ISO base media file analyzing unit(12), and encrypts only video/audio data except for the video and audio frame headers in the video and audio samples according to an encryption option. A hint information generating unit(14) changes a streaming packet charged load size in the hint sample to a value which is times of a block size used in a block encryption method and is smaller than an MTU(Maximum Transport Unit) size, and newly generates hint information when a hint track does not exist. A meta data generating unit(11) receives meta data necessary for streaming or downloading an encrypted moving picture file, and generates meta data structured to be suitable for the ISO base media file format. An ISO base media file configuring unit(15) receives an encrypted video/audio sample from the sample encrypting unit(13), receives hint track information corrected or newly generated from the hint information generating unit(14), receives structured meta data information from the meta data generating unit(11), and replaces an original video/audio sample in the original moving picture file with the encrypted video/audio samples. The ISO base media file configuring unit(15) replaces the hint track with a corrected hint track or adds a hint track when the hint track does not exist, inserts the meta data into a user definition area of the ISO base media file, and configures a moving picture file encrypted to be suitable for the ISO base media file format.
