Embodiment Construction

[0017] A method for generating Android APP device fingerprints applied to security risk control, wherein the device fingerprints include: a device identifier, a device unique code and an anti-counterfeit code.

[0018] Described android device fingerprint generation method comprises the following steps: S1: setting device identifier; Judging whether equipment is real machine; Read the cpu information of the mobile phone that APP is installed, if the hardware of cpu is then identified as emulator for Goldfish, otherwise it is true machine; if it is a real machine, set the device identifier to 1; if it is an emulator, set the device identifier to 2; S2: Set the unique code of the device; when installing the app for the first time, check whether the mac address and imei number of the device exist and whether Readable; if the mac address and imei number of the device both exist and are readable, then generate a 32-bit device unique code according to the preset rules as the device u...

Abstract

The invention specifically relates to an android APP equipment fingerprint generation method applied to security risk control. The method includes the following steps: S1, setting an equipment identifier to 1 for a real machine, and setting the equipment identifier to 2 for a simulator; S2, generating a 32-bit equipment unique code as an equipment unique code of the method; S3, extracting a key kof an APP program, arranging the key k and the equipment unique code in parallel to form a new sequence, calculating a corresponding md5 value based on the new sequence obtained by group arrangement,and taking the last three bits of the md5 value as a security code of the method; and S4, sequentially arranging the equipment identifier, the equipment unique code and the security code together to form a 36-bit character which is a fingerprint of the equipment. According to the method, results cannot be changed by the influence of recalculation; and the equipment fingerprint produced by the method has uniqueness and tamper-proof performance.

Description

technical field [0001] The invention relates to the field of Internet security risk control, in particular to a method for generating fingerprints of Android devices. Background technique [0002] "Handheld business hall" is an important mobile Internet product for mobile operators in terms of electronic channels. It has become a key target of hackers. At the same time, more anti-hacking cutting-edge technologies have emerged as the times require, and have won the favor of Internet and mobile enterprise risk control. Among them, the device fingerprinting technology is the most popular, and almost every anti-fraud company regards it as one of the key technologies for big data risk control. Currently in the Android system, the methods of identifying devices adopted by third-party operators can be divided into the following three categories: operating system information: Android ID; device-related information: IMEI, Build.Serial; Sim card-related information: IMSI, mobile pho...
