Description
Technical Field
The invention relates to the technical field of storage, in particular to a non-inductive control method, a system and equipment based on movable storage.
Background
In the current society, the movable memory is a strong demand of many people, and for specific crowds with confidential demands on data, it is particularly important to select the movable memory with the confidential function, such as government confidential information personnel, military police personnel, scientific research personnel, business plans, business negotiations and the like, which all pay great attention to the confidentiality of information.
In the existing control scheme based on the removable storage, a login interface is provided for the encryption function of the removable storage, whether based on a software or hardware mode, and a user inputs a correct login account number and a correct password to log in the storage space of the removable storage. Of course, the existing means of brushing face, fingerprint, iris and the like can well solve the problem of login authentication of the removable memory.
However, none of the existing removable storage based control schemes can solve the storage data security protection function of the removable storage during the time period when the user temporarily leaves. Although the existing control scheme based on the removable storage can encrypt the stored data, a system interface logout function is provided, the removable storage is moved out and automatically changed to an un-logged state, and the like, the above modes can start the stored data of the protection/security user when the user leaves, but the problem of inconvenient operation exists.
For example, the user only takes a cup of coffee, goes to a toilet, or takes a print/copy/fax transmission piece, but only 1 minute, and the operation process of exiting the storage security interface of the removable memory is cumbersome and inconvenient, so that a large number of users can select the bare computer of the removable memory to run, i.e. leave without exiting the storage security interface of the removable memory.
Or the user sometimes wants to leave in a short time, and the computer does not leave the sight range, such as taking coffee, printing documents and the like, and does not exit the security interface of the movable memory, but encounters an emergency or a colleague/leadership chat in the middle, even goes out and forgets to close the security interface of the movable memory.
However, the inventors found that at least the following problems exist in the prior art:
the existing control scheme based on the removable storage provides a login interface for the encryption function of the removable storage, whether based on a software or hardware mode, so that a user inputs a correct login account number and a correct password, and then log in the storage space of the removable memory, but in the time period when the user temporarily leaves, the user needs to operate the mode of closing the storage encryption function of the removable memory to start the security protection of the storage data of the removable memory, for example, a user needs to start the security protection of the stored data of the removable memory by operating a storage security interface of the removable memory to log out or moving out the removable memory to automatically return to an un-logged-in state, which is inconvenient to operate and cannot realize that the security protection of the stored data of the removable memory can be started invisibly without closing the storage encryption function of the removable memory by the user operation during a time period when the user temporarily leaves.
