Detailed Description
The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
As shown in fig. 1, the method for sharing community rectification information based on a block chain includes,
and constructing a community correction information data sharing platform, wherein the data sharing platform has a function of writing data into a block link interface to the outside and provides a function of an external data access interface. The data template configuration function of the data sharing platform comprises the following steps: JSON data template inquiry function; a JSON data template inputting function; JSON data template modifying function; and a JSON data template deleting function.
The data sharing platform comprises a digital identity and data space management system, a user data encryption and decryption system, a data communication management system, a block chain system and a data storage system;
registering, by the digital identity and data space management system, user data in a user information blockchain for a service, the user data including a personal digital identity and a legal digital identity;
setting a block chain gateway, carrying out identity authentication on each block visitor, and allowing an accessed user to access the data storage system through the block chain gateway;
based on the information sharing protocol, all nodes exchange blockchain data through blockchain gateways.
In this embodiment, the user data encryption and decryption system ensures that the transaction is added to the super account book fabric on the basis of using a symmetric encryption technology, and does not need a user to manage or memorize each symmetric key, and only encrypted data but not an original file are stored in an object storage, and the original file cannot be tampered, so that the data security is improved, and meanwhile, related information of the encrypted data is stored in a block chain, and the information is not only a trace for encryption, but also the data ownership is ensured.
All communication networks in the data communication management system use SSL, the communication capacity is taken as the basis, the access of an interface requires HTTPS, and SSL certificate is taken as a trust certificate to be processed in a client side SDK so as to prevent the attack behavior of a middleman.
The block chain system is a alliance chain, is managed and participated in by multiple parties, supports POD by a consensus mechanism, meets the node authorization mechanism and the failover capability, and comprises the following characteristics:
(1) must be a federation chain, with multiple parties co-hosting and participating;
(2) the block chaining-out time is not higher than 1 second;
(3) the block chain transaction confirmation time is not higher than 1 second;
(4) block chain TPS > = 1000;
(5) block storage requirements: the number of the empty blocks of the block is less than 10 percent;
(6) the block chain intelligent contract requires complete compatibility with a general intelligent contract and supports a general contract language identity;
(7) requiring consensus mechanisms to support POA;
(8) the node authorization mechanism is satisfied;
(9) meeting the failover capability.
The data storage system adopts a symmetric encryption technology, each encryption needs a symmetric key, if different data are encrypted by using the same key, the key is exposed to the risk that all encrypted data are cracked once the key is leaked, and if different data are encrypted by using different keys, the key management is very complicated, the trace retention and the right confirmation maintenance of the data encryption consume a large amount of manpower, and the leakage risk still exists.
As shown in fig. 2, the digital identity and data space management system registers user data in a user information blockchain, including:
firstly, converting a key seed of a user into a hash value through a SHA512 algorithm;
secondly, hashing the hash value after SHA512 again by using a Bcrypt algorithm;
thirdly, hashing the value subjected to Bcrypt hashing again by using AES 256;
fourthly, finally, the digital identity KEY of the individual or the legal person is generated.
In this embodiment, the private key is encrypted and protected by a scrypt encryption algorithm and stored, and the private keys of the user and the legal user are saved by using a keystore technology on a block chain.
To securely control access to the institution, the system assigns a digital identity to each restricted institution. Each authority can access the system only by means of its private key and the corresponding digital identity.
In this embodiment, a specific flow of accessing data for information sharing is as follows:
firstly, scanning a two-dimensional code by a user through an IMI system, acquiring a basic information function of a login user, and acquiring real-name authentication information of the login user; the background system confirms that the user information is legal, and the system finishes login operation;
wherein, the digital identity login of legal person includes: a manager login function; administrator additions and deletions; creating a digital identity; distributing keys and saving keys; improving the basic information function of the legal person; a corporate information query function; identity recovery and key update functions.
Secondly, the administrator can apply identity authentication to the block chain after meeting the conditions set by the administrator through the block chain definition access control, and can access the data of the first party and operate the data after obtaining permission, thereby effectively realizing the safe access and the effective use of the user data.
Third, new data must be added to a new block. And whether the block (and the transaction within the block) is legitimate is checked by computing a hash. Any node maintained can propose a new legal block, but must go through a certain consensus mechanism to reach agreement on the block finally selected.
Fourthly, the administrator defines the data access control rule def (data) according to the sensitivity degree of the data and expresses the access rule in the form of an intelligent contract to be deployed into the submit (contract) of the blockchain network. When accessing data, a user first needs to perform authentication v (id), AND if the user passes the authentication AND meets contract conditions C (condition), the user can obtain an identity token T, for example, T = { v (id) AND C (condition) }, AND the user can hold the token to access the data object.
In summary, the method of the embodiment is based on the block chain digital identity and data space technology, realizes data sharing of multiple departments, perfects the existing management mechanism, and realizes humanization, informatization, datamation and scientization of community correction work. The information intercommunication interconnection, office datamation and supervision full coverage of a plurality of departments are realized, real data can not be falsified, and the public, transparent and standard operation of community correction work is promoted.
