A multi-user shared U disk permission hierarchical management method and system

Abstract

The application is suitable for the field of authority management, and relates to a multi-user shared U disk authority hierarchical management method and system.The method comprises the following steps: configuring a basic authority quota corresponding to the physical capacity of a private partition for each user, and associating an adjustable credit score; when the first user data write-in amount reaches the basic authority quota, applying for a temporary authority quota to the second user based on the credit score and generating an authority mapping record; when the second user writes in data, temporarily storing the written data in an emergency partition and performing overdue judgment on the first user according to the authority mapping record; performing space recycling processing according to the judgment result and performing back migration on the data written in the emergency partition.The application changes static and passive storage space allocation into an active hierarchical management mode of flexible authority allocation based on credit dynamic evaluation, and significantly improves the storage resource utilization efficiency of the multi-user shared U disk.
