Abstract

The invention discloses a data storage method and device, a data acquisition method and device, equipment and a medium. The data storage method comprises the steps of obtaining a target data item identifier corresponding to target user data and a target authentication mode corresponding to the target data item identifier; generating a target certificate according to the target data item identifierand the target authentication mode; querying a target storage space corresponding to the target identity identifier in a blockchain account book; and storing the target voucher into the target storage space. According to the embodiment of the invention, the user data can be disclosed to a certain extent based on the preset authentication mode, so that the leakage of user privacy is avoided.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a data storage and acquisition method, device, equipment, and medium. Background technique [0002] At present, when a user handles business on a service platform such as an application (Application, App), website, etc., he needs to register an account on the service platform first, and then he can perform business. [0003] When a user registers an account on the service platform, the service platform usually requires the user to set an account password and fill in user data such as the user's identity information. After the service platform obtains the account password and user data set by the user, the service platform usually stores the user data in the platform server. Once the account name and password of the business platform are leaked, the user data in the platform server will be leaked, and then the privacy of the user will be leaked, causing troubles ...
