Abstract

A method for automatically authenticating unknown video data based on known video data stored at a client server is provided, wherein, unknown and known video data each are made up of segments and include metadata, a hash message digest, and a serial code. The method involves selecting a first segment of the unknown video and locating the serial code within the first segment of the unknown video data. The serial code is used to locate a corresponding first segment in the known video data. The first segment may include a known hash message digest. A new hash message digest for the first segment of the unknown video data is generated and compared with the known hash message digest. If they match, the segment of unknown video data is authentic.

Claims19

Dependent claims

A computer system comprising:

a processor;
and
memory storing processor-executable instructions that, when executed by the one or more processors, configure the computer system to cause the one or more processors to perform actions comprising:
receiving a video;
performing an authentication process on individual segments of the video;
determining, in response to authenticating a subset of the individual segments via the performing the authentication process, that the subset of the individual segments are unmodified video segments;
causing display of the unmodified video segments on a display screen;
and
causing display of an authentication graphic on the display screen, the authentication graphic indicating that the displayed unmodified video segments are unmodified,
wherein the subset of the individual segments is a first subset, the operations further comprising:
determining, in response to failing to authenticate a second subset of the individual segments during the authentication process, that the second subset of the individual segments are modified video segments.

8 more elements

A method comprising:

receiving a video;
determining, using an authentication process, that a first segment of the video is authentic, wherein the performing the authentication process comprises comparing a first hash associated with a message digest generated upon capture of the video clip with a second hash associated with a local message digest generated based at least in part on a hashing of the individual segments of the video;
determining, using the authentication process, a second segment of the video is inauthentic;
determining, based at least in part on determining the first segment of the video is authentic, that the first segment is an unmodified video segment;
causing display of the video on a display screen;
and
causing, during display of the first segment on the display screen during the display of the video, display of a graphic indicating that the displayed first segment is an unmodified video segment.

4 more elements

An electronic device comprising:

a display;
one or more processors;
and
memory storing processor-executable instructions that, when executed by the one or more processors, configure the electronic device to cause the one or more processors to perform actions comprising:
receiving a video;
determining, using an authentication process, that a first segment of the video is authentic, wherein the performing the authentication process comprises comparing a first hash associated with a message digest generated upon capture of the video clip with a second hash associated with a local message digest generated based at least in part on a hashing of the individual segments of the video;
determining, using the authentication process, that a second segment of the video is inauthentic;
determining, based at least in part on determining the first segment of the video is authentic, that the first segment is an unmodified video segment;
causing display of the video on the display;
and
causing, during display of the first segment on the display during the display of the video, display of a graphic indicating that the displayed first segment is an unmodified video segment.
