Abstract

The invention relates to a data pledge method and system, an electronic device and a storage medium, and the data pledge method comprises the steps: obtaining target data of a user side through responding to a pledge request of the user side, carrying out the local encryption of the target data through employing a preset encryption algorithm, obtaining a first ciphertext, and carrying out the local encryption of the target data based on a preset intelligent contract rule, performing Hash calculation on the first ciphertext to obtain a first Hash value, and transmitting the first Hash value to a block chain system of a guarantee party of the target data, so that the guarantee party compares the first Hash value with a second Hash value pre-uploaded by a user party, and when the first Hash value is consistent with the second Hash value, the target data is transmitted to the block chain system of the guarantee party of the target data. And providing a guarantee for the target data. According to the method, the authenticity of the encrypted pledge data is checked, so that the non-compliance behavior that the pledge data is unreal data can be avoided, and the safety of loan funds can be improved on the basis of improving the data safety.

Description

technical field [0001] This application relates to the field of blockchain technology, and in particular to a data pledge method, system, electronic device and storage medium. Background technique [0002] In order to promote the progress of technological innovation, the current financial policy supports technological innovation enterprises to obtain financial support from banks and financial institutions through data credit. [0003] In the process of enterprise data pledge, the methods of data custody pledge and data encryption pledge are usually adopted. Among them, data custody pledge cannot guarantee the security of data in the pledge process, and there is a problem of data leakage. The data encryption pledge cannot avoid non-compliant loan behaviors, resulting in the loss of loan funds. Therefore, the current data pledge cannot take into account data security issues and financial security issues. [0004] There is no effective solution to the problem that data secur...
