Description
Technical Field
The invention belongs to the technical field of block chains, and particularly relates to a service data processing method based on a block chain.
Background
With the development of computer technology, the block chain technology (also called distributed account book technology) is favored by its advantages of decentralization, transparency in disclosure, no tampering, trusty and the like, and is widely applied in many fields such as intelligent contracts, stock exchange, electronic commerce, internet of things, social communication, file storage, existence certification, identity verification, share rights and crowd funding and the like.
When a service system is implemented based on the blockchain technology, the service system (which may also be referred to as a blockchain system because the service system is implemented by using the blockchain technology) needs to write service data into the blockchain. After the block chain system receives the service data needing to be written into the block chain, the transactions are executed by adopting a first-in first-out queue according to the time sequence, and the operations of transaction verification, implementation, data link entering and the like are completed. There is also a need for a method for processing service data that can access a block chain system with multiple service types and meet the service processing requirements of different types of service data.
Disclosure of Invention
The invention aims to provide a service data processing method based on a block chain, which aims to solve the problem that the existing block chain technology is applicable to a service system and meets the requirements on adaptability of various service data.
The invention provides the following technical scheme:
a service data processing method based on a block chain comprises the following steps: s1, receiving a service transaction request of a client person by the block chain node, wherein the service transaction request comprises personal authentication data and service transaction data; s2, determining the user identification corresponding to the personal authentication data by the blockchain network, and performing client personal authentication through an authentication mechanism; s3, judging whether the client passes personal authentication, if so, determining the attribute of the service data by the block link points, and encrypting the service data according to the attribute; and S4, carrying out consensus processing on the encrypted service data by using a formula algorithm, and carrying out uplink processing on the service data.
Further, the consensus processing includes that a block chain node sends a pre-processing block including the service data to a consensus node, and the consensus node performs consensus verification on the pre-processing block; and if the preprocessing block passes the consensus verification, the block chain link point stores the preprocessing block into a block chain network.
Further, the attributes of the service data include a text type and an image type, and if the data attribute of the service data is the text type, the block link point encrypts the service data by using a preset private key of a public-private key pair corresponding to a user identifier included in the service data; and if the data attribute of the service data is the image type, the block chain node determines the abstract of the service data, and encrypts the abstract by using a preset private key of a public and private key pair corresponding to the user identifier contained in the service data.
Further, the user identifier includes a corresponding area, identity information, social information, and behavior habits of the user.
Further, the user identifier is a unique identifier corresponding to the authentication mechanism, and is used for identity authentication and preventing data from being tampered.
Further, the uplink processing of the service data includes storing the service data in a data field formed in the blockchain network, where the data field includes: version number, public key, signature, hash value of the block to which the block belongs, timestamp and service priority.
The invention has the beneficial effects that:
the invention relates to a service data processing method based on a block chain, which is based on the characteristics of non-tampering, decentralization, data encryption and trust transfer of a block chain technology, can select a matched block chain according to service attribute information of service data to be linked to complete the link entry, and establishes a block chain data recording table to record each block chain corresponding to a service type, so that different types of service data are processed differently, and the processing requirements of different types of service data in a block chain system can be met.

In the drawings:
FIG. 1 is a schematic flow diagram of the process of the present invention.
Detailed Description
As shown in fig. 1, a method for processing service data based on a block chain includes the following steps:
s1, receiving a service transaction request of a client person by the block chain node, wherein the service transaction request comprises personal authentication data and service transaction data;
s2, determining the user identification corresponding to the personal authentication data by the blockchain network, and performing client personal authentication through an authentication mechanism; the user identification comprises a region, identity information, social information and behavior habits corresponding to the user, and is the only identification corresponding to the authentication mechanism and used for identity authentication and preventing data from being tampered;
s3, judging whether the client passes personal authentication, if so, determining the attribute of the service data by the block link points, and encrypting the service data according to the attribute;
and S4, carrying out consensus processing on the encrypted service data by using a formula algorithm, and carrying out uplink processing on the service data.
Specifically, the consensus processing comprises that a block chain node sends a preprocessing block comprising service data to a consensus node, and the consensus node performs consensus verification on the preprocessing block; and if the preprocessing block passes the consensus verification, the block link point stores the preprocessing block into the block chain network.
Specifically, the attributes of the service data include a text type and an image type, and if the data attribute of the service data is the text type, the block link point encrypts the service data by using a preset private key of a public-private key pair corresponding to a user identifier included in the service data; and if the data attribute of the service data is the image type, determining the abstract of the service data by the block link point, and encrypting the abstract by using a preset private key of a public and private key pair corresponding to the user identifier contained in the service data.
Specifically, the uplink processing of the service data includes storing the service data in a block chain network to form a data field, where the data field includes: version number, public key, signature, hash value of the block to which the block belongs, timestamp and service priority.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
