Embodiment
For making objects and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the method for the disclosed a kind of protected data of the embodiment of the invention may further comprise the steps:
Step 011: the storer specific region is set to the protected data storage space;
Step 012: described space is provided with authority;
Step 013: data to be protected are saved to the protected data storage space;
Step 014: judge whether the operation to the protected data storage space has authority, if then the protected data storage space is operated.
Described authority to the setting of protected data storage space can be different from the data that do not need protection with described protected data; if certainly enough big the or common data of storage space itself not quite and have necessity of the protected data of being set to; also general data all can be set at protected data; and described general data all is stored in the protected data storage space; data space and protected data storage space can certainly be merged into a protected data storage space, and the space of whole merging is provided with authority.Whether, be protected data storage space, depend on whether this space is set specified permission and only allows protected data to preserve and the fetch program reads and/or writes if that is to say.For example; the function that in cell phone system, has factory reset usually; when the user has carried out the factory reset operation; system can change to return to Default Value its data with access rights; but some data that form in user's practice are arranged or be provided with etc.; the user does not wish to change; and by in storage space, setting the protected data storage space; with the data of not wishing to change or be provided with etc. and be stored in the described space; and the program of visiting this space is provided with authority; the program that only possesses authority just can read, as with default for not having authority, and illegal the deletion.After user's factory reset, program by having authority reads out the data of personalization or setting and is used, in case just can avoid over factory reset, the situation that all data or data all are modified takes place, and has brought convenience for user's use.
Concrete, being operating as of carrying out of described data read and/or write.For example; if for needs being carried out when data recovered preserves; just the protected data storage space is carried out data write operation,, then the data that are stored in this protected data storage space are carried out read operation if when need proposing this protected data.
