Obtaining a user access control value YH of a registered userRj(ii) a B3, b4, b5, b6 and b7 are all preset proportional coefficients, and lambda is a correction factor and takes the value of 0.83665; u shapeRjStoring the total times for the blocks of the registered users;
SS 6: and the personnel analysis module sends the user access control value of the registered user to the server for storage.
4. The intelligent access control system based on the block chain as claimed in claim 1, wherein the specific distribution and storage steps of the block chain module are as follows:
v1: the block chain module sends a storage acquisition instruction to a mobile phone terminal of a registered user, and marks the time for sending the storage acquisition instruction as an instruction sending time;
v2: after receiving a storage acquisition instruction through a mobile phone terminal, a registered user sends the residual memory to a block chain module through the mobile phone terminal; the block chain module marks the mobile phone terminal of the registered user receiving the residual memory as a storage node, and the storage node is represented by a symbol Mh, wherein h is 1, 2, … … and n; meanwhile, marking the time of receiving the residual memory as the instruction receiving time;
v3: calculating the time difference between the instruction sending time and the instruction receiving time to obtain the response time length of the storage node, and marking the response time length as T1Mh；
V4: setting all mobile phone models to correspond to a preset terminal value, matching the models of the storage nodes with all the mobile phone models to obtain corresponding preset terminal values, and marking the preset terminal values as KMh；
V5: calculating the time difference between the mobile phone purchasing time of the storage node and the current system time to obtain the purchasing duration of the storage node, and marking the purchasing duration as T2Mh；
V6: the response time length, the preset terminal value and the purchase time length are subjected to dequantization processing, the numerical values are obtained, and a formula is utilized
Obtaining a block value F of a storage nodeMh(ii) a Wherein b8, b9, b10 and b11 are all preset proportionality coefficients;
v7: selecting the storage node with the largest block value as a selected node; the block chain module compresses and encrypts the registration information, sends the compressed and encrypted registration information to the selected node for storage, and simultaneously performs block chain communication connection with the selected node; the total number of times of block storage of the selected node corresponding to the registered user is increased once.
