Problems solved by technology

[0004] After research, it is found that the method of this patent mainly has the following two problems: first, the user who obtains the root authority (root authority) can modify the information of the mac address arbitrarily, so the reliability of using the mac address as the unique code of the Android device is low ; Second, to obtain imei number information, you need to apply for the "android.permission.READ_PHONE_STATE" (access phone state) permission. This permission is a sensitive permission. Obtaining this permission requires the user's consent, which will affect the user experience. If the user does not agree, it will not be obtained. Need to obtain imei number information, and obtaining this permission will bring security threats

Abstract

The present invention relates to a method for extracting feature information of an Android device, comprising: extracting a process number and a process name; forming a final mapping table according to the process number and the process name; The process number and the process name are spliced ​​to form a character string; and the characteristic information of the Android device is formed according to the character string. The process information extracted by the present invention is a process number and a process name, the reliability of the feature information obtained through the process number and the process name is good, the feature information of the extracted Android device does not need to apply for sensitive permissions, the user experience is good, and the feature Information security is high.

Description

Technical field[0001]The present invention belongs to the technical field of device feature information, and in particular, a method for extracting feature information of an ANDROID device.Background technique[0002]Mobile ad is an advertisement displayed when accessing a mobile app or mobile web page via mobile devices (such as mobile phones, tablets, etc.), including: pictures, text, insert ads, links, videos, gravity sensing ads, etc. When a mobile advertisement provides a personalized service for different Android devices, you need to match and identify the intelligent terminal, so the device feature information is required.[0003]Currently, Android devices match and identify, typically borrow applications to read information in the system, such as the Mac (Media Access Control, Media Access Control) address, and IMEI (InternationalMobile Equipment Identity, mobile device international identity) Number and other information. In the disclosure: 107908948A, China patents named "an A...
