A multi-user security hard disk and a control method thereof

Abstract

The invention discloses a multi-user security hard disk and a control method thereof, the multi-user security hard disk at least comprises an interface module, a hard disk controller and a storage unit, and the interface module is used for carrying out data communication with a host; the storage unit opens up a plurality of independent partitions for multi-user data storage; the hard disk controller is connected with the interface module and the storage unit, is used for controlling the work of the storage unit according to an instruction of the host, and at least comprises a user authentication unit and a partition management unit, and the user authentication unit is used for carrying out user information authentication and sending authentication result information to the partition management unit; and the partition management unit is used for managing the corresponding partition of the storage unit according to the authenticated user information, so that the hard disk controller canonly perform read-write operation on the partition. Compared with the prior art, the physical isolation of each user data storage area is realized through the bottom chip of the storage equipment, sothat the data security performance is greatly improved.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a multi-user secure hard disk and a control method thereof. Background technique [0002] In a public computer application environment, multiple users usually share the hard disk space, such as teaching computers, different students use the same computer; public computers in the company, etc.; in a multi-user application environment, each user has his own private data , put forward a higher demand for data security. The existing technology usually uses software to isolate data of different users. However, in this way, the data among multiple users cannot be completely isolated in physical storage space, making it difficult to protect the data of individual users. [0003] In some multi-user applications, multiple operating systems are installed to meet the application requirements of different users. In the prior art, multiple operating systems are implemented by setting multip...

Problems solved by technology

However, the multi-user operating system data cannot be completely isolated, and only the access rights of users are limited through rights management. Once the rights management is broken, the data security barrier between multiple users will no longer exist. For example, it can be viewed through administrator rights. per user data
