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.

Claims (34)

1. A method for verifying video content, 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, and encrypted content 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 match files included in the video archive; and

in response to determining that the plurality of files indicated in the file list matches files included in the video archive, requesting a decryption key for decrypting the encrypted content.

2. The method of claim 1 , wherein determining that the plurality of files indicated in the file list matches the files included in the video archive further comprises determining whether a file of the plurality of files is missing from the video archive.

3. The method of claim 1 , wherein determining that the plurality of files indicated in the file list matches the files included in the video archive further comprises determining whether a file that is not included in the plurality of files is included in the video archive.

4. The method of claim 1 , further comprising verifying a signature corresponding to video metadata prior to determining whether the plurality of files indicated in the file list match files included in the video archive, wherein the video metadata and the signature corresponding to the video metadata are included in the video archive.

5. The method of claim 1 , wherein the encrypted content was received at a server from a second user device, and wherein the video archive is received by the user device from the server.

6. The method of claim 5 , further comprising verifying a signature corresponding to video metadata, wherein the video metadata indicates information about the second user device, and wherein the video metadata and the signature corresponding to the video metadata are included in the video archive.

7. The method of claim 1 , further comprising inhibiting a request for the decryption key for decrypting the encrypted content in response to determining that the plurality of files indicated in the file list does not match the files included in the video archive.

8. A system for verifying video content, the system comprising:

a hardware processor that:

receives, 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, and encrypted content corresponding to the video, and wherein the file list indicates a plurality of files that are to be included in the video archive;

verifies the signature corresponding to the file list;

in response to determining that the signature corresponding to the file list has been verified, determines whether the plurality of files indicated in the file list match files included in the video archive; and

in response to determining that the plurality of files indicated in the file list matches files included in the video archive, requests a decryption key for decrypting the encrypted content.

9. The system of claim 8 , wherein determining that the plurality of files indicated in the file list matches the files included in the video archive further comprises determining whether a file of the plurality of files is missing from the video archive.

10. The system of claim 8 , wherein determining that the plurality of files indicated in the file list matches the files included in the video archive further comprises determining whether a file that is not included in the plurality of files is included in the video archive.

11. The system of claim 8 , wherein the hardware processor further verifies a signature corresponding to video metadata prior to determining whether the plurality of files indicated in the file list match files included in the video archive, wherein the video metadata and the signature corresponding to the video metadata are included in the video archive.

12. The system of claim 8 , wherein the encrypted content was received at a server from a second user device, and wherein the video archive is received by the user device from the server.

13. The system of claim 12 , wherein the hardware processor further verifies a signature corresponding to video metadata, wherein the video metadata indicates information about the second user device, and wherein the video metadata and the signature corresponding to the video metadata are included in the video archive.

14. The system of claim 8 , wherein the hardware processor further inhibits a request for the decryption key for decrypting the encrypted content in response to determining that the plurality of files indicated in the file list does not match the files included in the video archive.

15. A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for verifying video content, 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, and encrypted content 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 match files included in the video archive; and

in response to determining that the plurality of files indicated in the file list matches files included in the video archive, requesting a decryption key for decrypting the encrypted content.

16. The non-transitory computer-readable medium of claim 15 , wherein determining that the plurality of files indicated in the file list matches the files included in the video archive further comprises determining whether a file of the plurality of files is missing from the video archive.

17. The non-transitory computer-readable medium of claim 15 , wherein determining that the plurality of files indicated in the file list matches the files included in the video archive further comprises determining whether a file that is not included in the plurality of files is included in the video archive.

18. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises verifying a signature corresponding to video metadata prior to determining whether the plurality of files indicated in the file list match files included in the video archive, wherein the video metadata and the signature corresponding to the video metadata are included in the video archive.

19. The non-transitory computer-readable medium of claim 15 , wherein the encrypted content was received at a server from a second user device, and wherein the video archive is received by the user device from the server.

20. The non-transitory computer-readable medium of claim 19 , wherein the method further comprises verifying a signature corresponding to video metadata, wherein the video metadata indicates information about the second user device, and wherein the video metadata and the signature corresponding to the video metadata are included in the video archive.

21. The non-transitory computer-readable medium of claim 15 , wherein the method further comprises inhibiting a request for the decryption key for decrypting the encrypted content in response to determining that the plurality of files indicated in the file list does not match the files included in the video archive.
