Embodiment 1

[0021] The present invention is as Figure 1-4 As shown, the present invention provides a method for anonymous identification of terminal equipment (VAID), comprising the following steps:

[0022] S1. Client SDK local anonymous device ID generation strategy

[0023] Locally generated VAID=version number+SHA256(AndroidID+Manufacture+Model). Collect the AndroidID of the system. If the collected AndroidID is empty or abnormal, a random string (d_fixed header followed by 16-bit random characters, such as d_85f5e85c62a64314) is used to cache locally. If the normal AndroidID of the system is obtained in the future, the system AndroidID shall prevail. If the system AndroidID abnormality cannot be obtained, the cached one shall prevail. The uploaded AndroidID must be consistent with the local AndroidID participating in the calculation of the VAID, and ensure that the AndroidID must not be empty. vaid has a version number, which identifies the vaid version (starting from d0) vaid sto...

Abstract

The invention discloses a terminal equipment anonymous identification (VAID) method. The method comprises the following steps: S1, a client sdk local anonymous equipment ID generation strategy; and S2, a server participates in anonymous device ID verification, when the client is started, the SDK can acquire some necessary information of the device without permission application, generates a VAID,uploads the VAID and equipment matching information to the server, and the server analyzes the legality of the uploaded VAID according to corresponding rules and returns the legality to the SDK to judge whether the local VAID needs to be rewritten or not. The method has the following beneficial effects: 1, permission is requested in a non-intrusive manner, user experience is friendly, and compliance requirements are met; 2, different from the traditional local single generation method, the front end and the rear end are linked, so that the anti-erasure and anti-tampering stability is greatly improved; and 3, the global uniqueness of the anonymous equipment ID is guaranteed.

Description

technical field [0001] The present invention relates to the field of wireless communication and terminals, in particular to a method and system for anonymous identification (VAID) of terminal equipment. Background technique [0002] For risk control modeling, security protection decision-making, Shence and other platform data analysis, improving product marketing user experience, etc., it is generally necessary to identify user devices, so it is hoped to obtain a stable, reliable and unique device identification code, but due to Android Due to limitations such as system version and bugs in the manufacturer's customized system, the stability and uniqueness of most similar generated device identification codes are not ideal at present. The identification of other hardware information also has different degrees of problems due to system version, mobile phone hardware and other restrictions. A single locally generated device ID has serious authority dependence, and it is diffic...
