s54: matching the mobile phone terminal model of the preferred user with all mobile phone terminal models to obtain a corresponding preset value, and marking the preset value as YRi；
S55: dequantizing the distance difference, the predicted duration, the response duration and the preset value, taking the values, and using a formula
Obtaining address processing value A of preferred userRi(ii) a Wherein d1, d2, d3 and d4 are all preset proportionality coefficients; wherein T3RiThe registration duration of the preferred user is the time difference between the current time of the system and the registration time of the preferred user;
s56: selecting the preferred user with the maximum address processing value as the selected user, generating a verification selection instruction by a verification issuing module, and sending the verification selection instruction to the mobile phone terminal of the selected user;
s6: the verification issuing module generates a verification and selection instruction to a mobile phone terminal of a selected user, the selected user arrives at the address to be processed at the expected arrival time of the address to be processed after receiving the verification and selection instruction, then a plurality of photos of the address to be processed are shot through the mobile phone terminal, then the photos of the address to be processed are combined to form a photo set, the photo set is compressed to obtain picture information, the selected user sends the picture information to the verification issuing module through the mobile phone terminal, and meanwhile the total shooting times of the selected user are increased once;
s7: the verification issuing module receives the picture information and sends the picture information to the issuing verification module;
step two: the issuing auditing module receives the corresponding picture information and sends the picture information to a computer terminal of a license issuing department;
step three: the staff of the license issuing department verifies the license data and the picture information through the computer terminal, and after the verification is successful, the license data and the picture information are marked as block chain license storage data and sent to the server;
the server receives the block chain license storage data and then sends the block chain license storage data to the data management module;
the data management module is used for processing the block chain license storage data and distributing the block chain license storage data to the corresponding nodes for storage; the distribution process is as follows: firstly, carrying out data chaining on block chain license stored data to obtain new block data; marking the node as Fm, acquiring the residual memory capacity of the node and marking the node as SYFmAcquiring the position of the node, and calculating the distance difference between the position of the node and the address in the new block data to obtain the distance difference JFmDequantizing the residual memory capacity and the pitch difference and taking the value thereof, using the formula HFm=SYFm×d5+JFm× d6, and finally the data management module sends the new block data to the node with the maximum node storage value for storage, wherein d5 and d6 are both preset proportionality coefficients;
the block chain storage module comprises a plurality of nodes for storing data.
2. The block chain-based license issuance security management system according to claim 1, further comprising a registration login module, wherein the registration login module is configured to submit registration information for registration by a user and send the registration information that is successfully registered to a server for storage; the registration information comprises a name, an identity card number, a mobile phone number and a model of a mobile phone terminal; the server marks the user receiving the registration information as a registered user, and marks the time when the registration information is received as the registration time of the registered user.
3. The block chain-based license issuance security management system according to claim 1, further comprising a number ordering unit and a query adjusting unit in the issuance auditing module; the serial number sequencing unit is used for sequencing the license data in sequence according to the receiving time and generating serial numbers of the license data, and sequentially sending the license data to a computer terminal of a license issuing department according to the serial numbers; the inquiry adjusting unit is used for checking the number of the license data and adjusting the number by the registered user through the mobile phone terminal, and the specific adjusting steps are as follows:
v1: a registered user sends a number exchange instruction to an inquiry adjusting unit through a mobile phone terminal, and the inquiry adjusting unit acquires the registration duration, the total shooting times and the total replacement value and the total adjustment value of the registered user;
v2: setting the total shooting times of the registered users as WLkThe registration time of the registered user is T3Lk(ii) a Total replacement value Z1Lk(ii) a Adjusting the total value to Z2Lk(ii) a When the registered user is the first query and adjustment, the value of the total replacement value and the total adjustment value is zero;
v3: using the formula WULk=WLk×d7+T3Lk×d8+Z1Lk-Z2LkObtaining a user value WU of a registered userLk(ii) a Wherein d7 and d8 are both preset proportionality coefficients;
v4: dividing the user value of the registered user by a preset conversion coefficient and rounding to obtain an adjustment quantity MT; simultaneously marking the registered user as a user needing to be called;
v5: the registered users with the numbers which are adjacent to the MT numbers before the demand users are marked as the adjusting users, and are sorted according to the numbers;
v6: firstly, sending an interchange regulation instruction to a mobile phone terminal of a regulation user with the most front serial number, sending an agreement instruction to an inquiry regulation unit by the regulation user with the most front serial number in a preset time range through the mobile phone terminal, after receiving the agreement instruction, exchanging the serial number of a user to be called with the serial number of the regulation user with the most front serial number, and simultaneously obtaining a single conversion value DH by using a formula DH = MT × d9, wherein d9 is a preset proportionality coefficient; increasing the single conversion value DH for the adjustment total value of the user to be adjusted, and increasing the single conversion value DH for the replacement total value of the adjustment user with the most serial number; and when the inquiry adjusting unit does not receive the agreement instruction sent by the last adjusting user in the sequence within the preset time range, the adjustment fails, an adjustment failure instruction is generated, and the inquiry adjusting unit sends the adjustment failure instruction to the mobile phone terminal of the user in need.
