Abstract:
Methods, systems, and media for protecting and verifying video files are provided. In some embodiments, a method for verifying video streams is provided, the method comprising: receiving, at a user device, a request to present a video that is associated with a video archive, wherein the video archive includes a file list, a signature corresponding to the file list, video metadata, a signature corresponding to the video metadata, and at least one encrypted video stream corresponding to the video, and wherein the file list indicates a plurality of files that are to be included in the video archive; verifying the signature corresponding to the file list; in response to determining that the signature corresponding to the file list has been verified, determining whether the plurality of files indicated in the file list are included in the video archive; in response to determining that the plurality of files indicated in the file list are included in the video archive, verifying the signature corresponding to the video metadata; in response to determining that the signature corresponding to the video metadata has been verified, requesting a decryption key corresponding to the video stream; in response to receiving the decryption key, decrypting the encrypted video stream; and causing the decrypted video stream to be presented on the user device.
