1. a kind of vision operation record protection method based on block chain, it is characterised in that:

  • Include following steps:



    One)

    Video modification record enters block for the first time:

    1)

    Video is sent to video server by video terminal;

    2)

    Video server gives one identifier of the video distribution;

    3)

    Video server calculates the cryptographic Hash of the video;

    4)

    Video identifier, timestamp and video cryptographic Hash are combined into video modification record and are sent to block chain by video serverServer;

    5)

    Block chain server creates new block and stores video modification record;



    Two)

    Video enters block flow by modification rear video modification record:

    6)

    User changes the video on video server;

    7)

    Video server calculates the cryptographic Hash of modified video;

    8)

    The cryptographic Hash of video identifier, timestamp and modification rear video is combined into newest video modification and remembered by video serverRecord is sent to block chain server;

    9)

    Block chain server according to the identifier of video traverses block and finds a nearest video of timestamp from back to front to be repaiiedChange record;

    10)

    The cryptographic Hash of the nearest video modification record of block chain server computation times stamp is as last video modificationThe cryptographic Hash of record;

    11)

    Block where cryptographic Hash that block chain server records last video modification, last video modification recordCryptographic Hash and the record combination of newest video modification form video modification record deposit block.
