Embodiment 1

[0042] When the third application A accesses the camera permission and sends a camera permission request, and this camera permission request meets the query frequency f, the user responds to the camera permission request, that is, the user makes a decision, and stores the current camera decision request, decision information and environmental information; this data is then used to train a decision model.

Embodiment 2

[0044] When the third application B accesses the microphone permission and sends a microphone permission request, and this microphone permission request does not meet the inquiry frequency f; therefore, the decision model makes a decision on this microphone permission request, and then verifies the decision information; the verification result is correct , then reduce the query frequency f, store the microphone decision request, decision information and environment information at the same time, and use the data to train the decision model.

Embodiment 3

[0046] When the third application C accesses the storage permission and sends a storage permission request, and this storage permission request does not meet the inquiry frequency f; therefore, the decision model makes a decision on this storage permission request, and then verifies its decision information; the verification result is If it is wrong, increase the query frequency f, store the storage decision request, decision information and environment information at the same time, and use the data to train the decision model.

Abstract

The invention discloses a method for automatically generating user privacy policies and its device, and a handheld device, including a monitor for obtaining sensitive resource requests from third-party applications; a response module for setting the inquiry frequency f, and if the condition of the inquiry frequency f is met, Respond to the sensitive resource request, and obtain the decision information and the environmental information corresponding to the decision information; the intelligent decision module establishes a decision model through the incremental decision tree algorithm and the rule-based classification algorithm; if the condition of the query frequency f is not met, the The decision-making model makes a decision on the sensitive resource request of the monitor, and obtains the decision information and the environment information corresponding to the decision information; the data collector collects and stores the decision information and the environment information corresponding to the decision information. The method solves the disadvantage that the existing privacy protection method needs the user's full participation, and the problem that it leads to failure of the application function.

Description

technical field [0001] The invention belongs to the technical field of user privacy protection, and also relates to the application technical field of machine learning algorithms; in particular, it relates to a method and device for automatically generating user privacy policies, and also relates to a handheld device based on the above device. Background technique [0002] With the continuous popularization of smart phones, the leakage of user privacy on mobile terminals is becoming more and more serious. In order to prevent the leakage of user privacy information, Android provides a simple permission management method, which requires developers to clearly indicate the mobile phone resources required by the App in the manifest file when developing the App. When installing the App, the user either chooses to agree to all resource requests in the list, or gives up installing the App. Once a user has installed the app, the only way they can revoke a permission is to uninstall ...
