Problems solved by technology

In traditional information systems, data is stored in business databases (for example, relational or non-relational databases, etc.) in a formatted form, which is not easy to expand, and data writing and reading operations are performed by effective users of the database. implement
In other words, if the user name and corresponding password of the database are leaked, the data stored in the database will encounter problems such as loss, theft, or malicious tampering, as well as challenges such as difficult identification and time fixing

Abstract

The embodiment of the invention discloses a data storage method and device based on a block chain. The method comprises the following steps: receiving a data writing request, service data and first user information for identifying a first user from the first user; calculating the service data to generate a first characteristic value; based on the data type and / or data size of the service data, determining storage data and mode information associated with the service data, the storage data comprising the first characteristic value, and the mode information representing a generation mode of thestorage data; and storing the storage data, the mode information and the first user information in a blockchain account book in an associated manner based on the data writing request. Compared with the traditional data storage method, the technical scheme disclosed by the invention can ensure the safe and reliable storage of the data for electronic storage, and provides the validity verification of the data.

Description

technical field [0001] The present disclosure generally relates to the field of information security, and in particular relates to a blockchain-based data storage method, device and corresponding computer-readable storage medium. Background technique [0002] Blockchain (block chain) is a new type of distributed system that combines computer technologies such as distributed data storage, point-to-point transmission, encryption algorithm and consensus mechanism. It maintains a set of distributed ledgers jointly by multiple participating nodes, realizing The tamper-proof and traceable characteristics of data information create a secure distributed trust system. [0003] With the development of Internet technology, more and more business data (for example, electronic contracts, electronic certificates, digital assets, etc.) are stored in the information system (for example, electronic depository system, etc.) in the form of electronic data. In traditional information systems, ...
