Abstract

The invention provides a block chain-based data file access control method, medium and device, and the method comprises the steps: querying an access control table stored in a block chain in response to an access request for a data file from a requester, so as to verify whether the access request is authorized or not; when it is verified that the access request of the requester is authorized, querying a denial of service information table stored in a block chain to verify whether the access request of the requester is legal; and providing the requested data file for the requester under the condition that the access request of the requester is verified to be legal.

Description

technical field [0001] The present disclosure relates to the fields of cloud computing and the Internet of Things, and in particular relates to a blockchain-based data file access control method, medium and device. Background technique [0002] With the development of communication technology, user data continues to increase, and data sharing and integration has also become a trend. However, the security and privacy risks brought about by sharing and querying data are the biggest challenges for cloud storage. It is particularly important to ensure the security, confidentiality and integrity of data while ensuring that authorized users can access legally. Commonly used access control models (such as Discretionary Access Control (DAC), Role-Based Access Control (RBAC), Attribute-Based Access Control (ABAC), Authority-Based Access Control (CaBAC), etc.) are implemented through a Centralized access paths, if a single point is hijacked, will suffer security risks. In view of t...
