Problems solved by technology

In the existing technology, there is no particularly good way to deal with the abnormal data collection caused by this new type of mobile phone or the release of the new version of the system. It can only be avoided by updating the SDK and background system immediately after this situation occurs, and self-discovery cannot be achieved. self-healing

Abstract

The invention discloses a method and device for detecting whether a device fingerprint collides with a risk control system. The method includes the following steps: S1. The Internet terminal device collects device environment information and reports it to the device fingerprint service; S2. The device fingerprint system collects data After decryption and analysis, the device environment information and network environment information are sent to the decision-making system together. The device environment information and network environment information contain several features; S3. The decision-making system calculates and judges each The repetition rate and null value rate of each feature. For the feature whose repetition rate exceeds the preset first threshold or the null value rate exceeds the preset second threshold, it is marked as an abnormal feature. The device fingerprint system adjusts in real time according to the abnormal feature to avoid fingerprinting. Calculations collide.

Description

technical field [0001] The invention relates to the field of computer and network communication, in particular to a method and device for detecting whether device fingerprints collide with a wind control system. Background technique [0002] Device fingerprint technology is a relatively common technology in the Internet field, especially in the field of business security, and is a basic security service. Its purpose is to collect a series of characteristic information of the device and send it to the server. After algorithm analysis and matching, the server generates a unique identifier for each device. The specific workflow is as follows: figure 1 shown. [0003] The device fingerprint application has two core indicators, uniqueness and stability. The uniqueness is that different devices need to generate different fingerprints. If different devices calculate the same fingerprint, a collision occurs. Stability means that after the device undergoes some operations, such as...
