the editing mode of presetting the coincidence threshold in the threshold module (8) is as follows: manually performing custom editing on the overlapping length of the data characters;
the management module (1) is interactively connected with the storage library (2) and the transaction module (9) through a wireless network, the transaction module (9) is interactively connected with the information acquisition module (10) through the wireless network, the information acquisition module (10) is interactively connected with the marking module (11) through the wireless network, the marking module (11) is interactively connected with the prediction evaluation module (12) through the wireless network, the storage library (2) is interactively connected with the docking module (6) through the wireless network, the docking module (6) is interactively connected with the grabbing matching module (7) through the wireless network, the login module (5) is interactively connected with the docking module (6) through the wireless network, the grabbing matching module (7) is interactively connected with the threshold module (8) through the wireless network, and the alarm module (13) is interactively connected with the threshold module (8) and the prediction evaluation module (12) through the wireless network;
the implementation method of the digital copyright protection system comprises the following steps:
step 1: registering the resource name, the author information and the release time of the digital copyright, and confirming the legality of the digital copyright;
step 2: performing tamper-proof processing on the registered digital copyright resource information, uploading tamper-proof processed data to a blockchain, performing distributed storage on the digital copyright resource information, and authorizing management;
step 3: in the database, the stored digital information is identified and classified under the exclusive label;
step 4: the user logs in the system, inputs the digital copyright information, acquires the key characteristics of the digital copyright information, indexes the digital copyright information in a database, analyzes the coincidence value of the digital copyright information, and alarms after exceeding a preset coincidence threshold;
step 5: in the trading stage, trade information of both sides to be traded is checked, historical trade records of digital rights are traced, ownership of the rights and trade flow are ascertained, and after risk assessment, early warning is carried out on high risk trade;
the tamper-proof processing in the step 2 is as follows: hashing, compressing the registered digital copyright resource into unique irreversible digital fingerprints;
in the process of carrying out distributed storage on digital edition right resources in the step 2, intersymbol interference is reduced by analyzing transmission channel characteristics, multipath mobile data transmission balance control is realized, and a calculation formula of the transmission channel characteristics is as follows:
；
wherein: k is a characteristic quantity of a mobile data transmission channel; q is the multi-path transmission allocation frequency band;characteristic response quantity for multipath transmission channels; />Bandwidth for the mobile data transmission channel; f is an iterative post-function of the critical beam features;
the alarm behaviors in the step 4 and the step 5 are specifically shown as follows: the client side popup window reminds, short message reminds and manager limit transaction reminds.
