Detailed Description
The present invention is further described in the following with reference to the drawings and the specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention, and the embodiments and the technical features of the embodiments can be combined with each other without conflict.
The embodiment of the invention provides a garbage classification credit score construction system and method based on a block chain, which are used for solving the technical problem of how to establish garbage classification credit scores of users.
Example 1:
the invention discloses a garbage classification credit score construction system based on a block chain. Both the user terminal and the garbage collection terminal are interconnected with the blockchain data.
The user terminal is a terminal APP, and the terminal can be a mobile phone or a tablet computer or a computer. The user terminal is used for applying for an account number on the block chain for each user to store the related information of the user, obtaining the user information and the key pair corresponding to each user, encrypting the user information through the key pair, and uploading the public key and the encrypted user information to the block chain.
The user applies for an account number on the blockchain through the user terminal and generates a key pair corresponding to the user, wherein the key pair comprises a public key and a private key. The private key is stored in the corresponding user terminal, and the public key uploads the blockchain.
The user information comprises private data and public data, the private data is only limited to be viewed by the user, and the public data allows others to view. After the user terminal obtains the user information, the public data is encrypted through the public key, the private data is encrypted through the private key, and then the encrypted public data and the encrypted private data are uploaded to the block chain.
The garbage collection end is used for obtaining garbage throwing data and a public key corresponding to each user, encrypting the corresponding garbage throwing data through the public key, uploading the encrypted garbage throwing data to the block chain, and the garbage throwing data is used for evaluating garbage classification credit.
In this embodiment, the rubbish collection end includes rubbish scanning terminal and data entry terminal, and rubbish scanning terminal is an X-ray machine, and the data entry terminal is rubbish collection APP, and rubbish collection APP is towards rubbish recovery staff, gathers rubbish through the X-ray machine and puts in data, and wherein rubbish is put in data and is included rubbish input volume and rubbish classification result, and the rubbish classification result is used for the sign rubbish classification whether correct.
After collecting the data that the user put in rubbish through X-ray machine, rubbish recovery staff puts in data entry rubbish collection APP with user's rubbish, and rubbish collection APP obtains the public key that the user corresponds from the block chain and after encrypting rubbish through the public key and putting in data, puts in data upload block chain with encrypted rubbish.
And a user account system is formed on the block chain, a public key, user information and junk putting data of each user are stored, the public key, the user information and the junk putting data of each user are evaluated to generate credit points, and the credit points are encrypted through the corresponding public keys.
Specifically, after the block chain receives the encrypted user information, the correctness of the encrypted user information is verified through the corresponding public key, the encrypted user information which meets the rule is allowed to be added into the block chain, and the encrypted user information which does not meet the rule cannot be stored into the block chain. Thereby ensuring the correctness of the user information stored on the block chain.
At the same time, the blockchain fulfills its function: evaluating the garbage putting data of each user to generate credit points, wherein the credit points are realized by the following functions:
carrying out structuralization processing on the obtained garbage throwing data, wherein the structuralization processing comprises the steps of converting the garbage throwing data into data with a preset format and discarding all incomplete data and data with errors;
calculating a score corresponding to the garbage throwing data according to a preset quantification rule;
and calculating the credit score of the user by integrating historical scores in a preset period.
Through the above functions, after the block chain acquires the garbage input data of the user at each time, the garbage input data is structurally processed to obtain data in a certain format, and the acquired garbage input data is converted into data in a Jason format in the block chain in this embodiment.
For each acquired garbage throwing data, a score is quantized in a block chain according to a preset rule, and the calculation method in the embodiment is as follows: and dividing the garbage amount correctly classified by the user by the total garbage amount thrown into the user to obtain a score corresponding to the garbage throw of the user.
Meanwhile, historical scores of the user in a preset period are integrated in the block chain to calculate credit points of the user. For example, each user initially receives 100 hidden credits in a monthly cycle, and if the user has garbage delivery activity during the month and all delivery records remain above 90%, a credit score of 1 point can be obtained, up to 120. If the record of the release is lower than 80%, 1-point credit score is lost, and the lowest score is not lower than 0.
The scores and the credit scores are stored in the block chain after being encrypted by the corresponding public keys, so that the user can conveniently check the scores of the user who puts garbage each time and the credit scores corresponding to the periods.
As a further improvement, the blockchain is further used for summarizing credit points of the users in a preset period, calculating reward points of the users according to a preset reward rule, and encrypting the reward points of the users through corresponding public keys.
For example, in a month period, if the user has garbage throwing behavior and no throwing record in the month is lower than 80%, the average score of the throwing record multiplied by the credit score can be obtained as the reward point of the month.
Example 2:
the invention discloses a garbage classification credit score construction method based on a block chain, which evaluates the garbage classification credit score of each user through a garbage classification credit score construction system based on the block chain disclosed by embodiment 1.
The method comprises the following steps:
s100, generating an account for each user on a block chain for storing relevant information of the user;
s200, acquiring user information and a key pair of a user, and uploading the encrypted user information to a block chain after encrypting the user information through the key pair;

s400, evaluating the junk putting data of each user through a block chain to generate credit points, and encrypting the credit points based on the corresponding public keys.
The user applies for an account number on the blockchain through the user terminal and generates a key pair corresponding to the user, wherein the key pair comprises a public key and a private key. The private key is stored in the corresponding user terminal, and the public key uploads the blockchain.
The user information comprises private data and public data, the private data is only limited to be viewed by the user, and the public data allows others to view.
After encrypting the user information through the key pair, uploading the encrypted user information to the blockchain, comprising the following steps:

Meanwhile, historical scores of the user in a preset period are integrated in the block chain to calculate credit points of the user. For example, each user initially receives 100 hidden credits in a monthly cycle, and if the user has garbage delivery activity during the month and all delivery records remain above 90%, a credit score of 1 point can be obtained, up to 120. If the record of the release is lower than 80%, 1-point credit score is lost, and the lowest score is not lower than 0.
The scores and the credit scores are stored in the block chain after being encrypted by the corresponding public keys, so that the user can conveniently check the scores of the user who puts garbage each time and the credit scores corresponding to the periods.
