In order to solve the above technical problems, on one hand, a general platform of a security service organization needs to be constructed, organization or individual information for developing security service business is collected on the platform, the platform performs real name authentication and business level test on the organization or individual of the security service business to provide for corresponding clients to perform screening, and on the other hand, the security service information generated in the security service process belongs to private information of the clients, the platform cannot be involved and stored, and is encrypted and distributed in a block chain information platform through a block chain technology.
The solution of the technical problem mainly depends on the block chain technology, and the block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The method is essentially a decentralized database, uses a block chain technology in the security service process, and has two functions, namely, a security service demander signs a contract signed by an organization or an individual providing security service business and provides a public key to a node on the block chain, and the node on the block chain performs system verification on the contract signed by the individual according to the provided public key to determine the correctness of the contract. On the other hand, the organization or the individual who provides the security service business encrypts the contract of the security service and the information collected and generated in the service process by using the public key of the security service demander, and the security service demander can decrypt the information by using the private key, store the decrypted information locally and further supply the information to the next security service organization or the individual. The contract and the security service information which are encrypted by the public key are stored in the block chain, and in order to enable each node in the block chain to have the incentive to carry out the encrypted contract and security service information recording, the general certificate reward is introduced. The voucher can be exchanged for a commodity and then mortgage and replaced at a pawn. According to the method and the system, a block chain technology is used, and the problems of asymmetric information and the like of the two parties of the existing security service mechanism or the individual are solved by calling the uplink data, so that the trust cost is greatly reduced, and the efficiency of security service is improved.

The construction and execution of the intelligent contract are described in detail below.
1. The security service provider and the security service demander participate together to make an intelligent contract
(1) Firstly, a security service provider and a security service demander must register as a user of a block chain, and the block chain is returned to the security service provider and the security service demander by a pair of public keys and private keys; the public key is used as an account address of a security service provider and a security service demander on a blockchain, and the private key is used as a unique key for operating the account.
(2) Two or more than two safety service providers and safety service demanders agree a commitment according to the needs, and the commitment comprises the rights and obligations of both parties; these rights and obligations program the machine language in an electronic manner; the participants use respective private keys to sign; to ensure the validity of the contract.
(3) The signed intelligent contract is transmitted into the blockchain network according to the promised content and the information collected and generated in the service process.
2. Contracts are flooded across the P2P network and stored in block chains
(1) The contracts are diffused in the whole block chain network in a mode of P2P, and each node receives one contract; the verification node in the block chain can firstly store the received contract into the memory, wait for a new round of consensus time and trigger consensus and processing of the contract.
(2) When the consensus time is up, the verification node packs all contracts stored in the latest period of time into a contract set (set), calculates the Hash value of the contract set, and finally assembles the Hash value of the contract set into a block structure to be diffused to the whole network; after receiving the block structure, other verification nodes take out the Hash of the contract set contained in the block structure and compare the Hash with the contract set stored by the other verification nodes; simultaneously sending a contract set approved by the user to other verification nodes; through such multiple rounds of sending and comparing; all the verification nodes eventually agree on the latest contract set within a specified time.
(3) The newly agreed contract set is spread across the network in blocks, each block containing the following information: the Hash value of the current block, the Hash value of the previous block, the timestamp when consensus is achieved, and other description information; the most important information of the block chain in the same time is a set of contracts with agreed consensus; and the nodes receiving the contract set verify each contract, and the verified contract is finally written into the block chain, wherein the verified content is mainly whether the private key signature of the contract participant is matched with the account.
3. Intelligent contract automatic execution for blockchain construction
(1) The intelligent contracts can regularly check the state of the automaton and traverse the state machine, the affairs and the triggering conditions contained in each contract one by one; pushing the transaction meeting the condition to a queue to be verified, and waiting for consensus; transactions that do not meet the trigger condition will continue to be deposited on the blockchain.
(2) The latest round of verified transactions can be diffused to each verification node, and the verification nodes firstly carry out signature verification to ensure the validity of the transactions as common block chain transactions or transactions; the transaction passing the verification enters a to-be-identified set, and after most verification nodes achieve the identification, the transaction is successfully executed and the user is informed.
(3) After the transaction is successfully executed, the state opportunity of the intelligent contract judges the state of the contract, and when all the transactions included in the contract are sequentially executed, the state opportunity marks the state of the contract as complete and removes the contract from the latest block; otherwise, the mark is marked as in progress, and the mark is continuously stored in the latest block to wait for the next round of processing until the processing is finished; the whole transaction and state processing is automatically completed by an intelligent contract system arranged in the bottom layer of the block chain, and the whole process is transparent and cannot be tampered.
Has the advantages that:
1. through the established security service platform, a plurality of social service organizations or individuals (such as security service companies and individuals working on security services) serve a plurality of private security requirement organizations or individuals under the mode, and clients can freely select the satisfied service organizations or individuals according to the requirements of the clients, so that a large number of private security service requirements on the market can be met.
2. In the security service process, the blockchain technology is used, and the two roles are that on one hand, a security service demander signs a contract signed with an organization or an individual providing security service business, and provides a public key to a node on the blockchain, and the node on the blockchain performs system verification on the signed contract according to the provided public key to determine the correctness of the contract. On the other hand, the organization or the individual who provides the security service business encrypts the contract of the security service and the information collected and generated in the service process by using the public key of the security service demander, and the security service demander can decrypt the information by using the private key, store the decrypted information locally and further supply the information to the next security service organization or the individual. The contract and the security service information which are encrypted by the public key are stored in the block chain, so that the security service contract between a service organization or an individual and a client is ensured to be executed without discount on the premise of ensuring privacy, and the security service information mastered by the security service organization or the individual can be accurately transmitted to the next service organization or the individual without tampering.
