Abstract
A method and device for improving data storage security, related to the technical field of cloud storage is disclosed. The method includes: detecting access counts of user data sets in a cloud storage resource pool, where the user data sets in the cloud storage resource pool are data obtained by encoding with an erasure coding algorithm of a first security level; determining a first user data set whose access count in the cloud storage resource pool meets a preset condition; obtaining a second security level according to attribute information of the cloud storage resource pool, wherein the attribute information includes the first security level and an increment for security step; and re-encoding the first user data set with an erasure coding algorithm of the second security level to obtain re-encoded first user data sets.
