If the function of generating the virtual data is started, when the application program acquires the real data, the mobile phone generates corresponding virtual data according to the attribute type (short message, call record, mail, address book and the like) of the real data to be acquired by the application program. The virtual data is corresponding to the format, type and the like of the real data, and the effect of falsifying and falsifying can be achieved. In this way, the virtual data is obtained by the application program, and the real data is correspondingly protected.
Before generating the virtual data, a feature library (a first preset database) and a context-aware library (a second preset database) of various attribute types can be established in the mobile phone. For example, the text content of the short message corresponds to a feature library of the text content of the short message, the address book corresponds to a feature library of the address book, and the mail content corresponds to a feature library of the mail content. These feature libraries are a structure similar to conditions plus decisions, indicating what decisions need to be made under what conditions are met. Before the feature library works, the feature library needs to be trained through a data source (keywords). The data sources are also the same structure of conditions plus decisions, and each piece of data corresponds to information about what kind of decision is made under a certain condition. After training of a large number of data sources (according to the principle of highest use frequency, selecting a target virtual word with the highest use frequency from a plurality of virtual words as a virtual word corresponding to any keyword), the feature library can make relevant decisions according to conditions more accurately. The user can also train the feature library, and can set conditions and make decisions by himself to be added to the feature library. The context-aware library is similar to the feature library, but is responsible for generating more logical virtual data (determining an application scenario of real data according to at least one keyword; searching a second preset database for scenario data bound with the application scenario according to the application scenario; merging the virtual data and the scenario data so that the first application program obtains the merged final virtual data), and after the feature library and the context-aware library are obtained, the virtual data can be generated through the context-aware library.
