Method of securing authenticity and evidentiary status of video recording, terminal device, and computer readable storage medium applying the method

A terminal device comprises:

• a storage medium;
• and
• a processor,
• wherein the storage medium stores computer programs, and
• the processor executes the computer programs to implement the following:
• acquiring an instruction to apply time labeling, and labeling each recorded video with a timestamp based on the instruction of time labeling;
• generating first mark information based on a content of each recorded video and uploading the first mark information and the timestamp into a blockchain;
• generating second mark information based on a content of at least one to-be-checked video;
• the at least one to-be-check video is one or all of the recorded videos;
• determining whether the first mark information is the same as the second mark information;
• finding the to-be-checked video to be undistorted and authentic if it is determined that the first mark information is the same as the second mark information;
• and
• finding the to-be-checked video to be non-authentic if it is determined that the first mark information is different from the second mark information.

A computer readable storage medium, the computer readable storage medium stores computer programs, and the computer programs are executed by at least one processor to implement the following steps:

• acquiring an instruction to apply time labeling, and labeling each recorded video with a timestamp based on the instruction of time labeling;
• generating first mark information based on a content of each recorded video and uploading the first mark information and the timestamp into a blockchain;
• generating second mark information based on a content of at least one to-be-checked video;
• the at least one to-be-check video is one or all of the recorded videos;
• determining whether the first mark information is the same as the second mark information;
• finding the to-be-checked video to be undistorted and authentic if it is determined that the first mark information is the same as the second mark information;
• and
• finding the to-be-checked video to be non-authentic if it is determined that the first mark information is different from the second mark information.
