Embodiment 1

[0040] figure 1 A schematic flowchart of a method for determining device fingerprints based on similarity according to Embodiment 1 of the present invention is shown. Such as figure 1 As shown, the method includes the following steps:

[0041] Step S100, extracting multiple device attribute data records belonging to the same operating system type in the device fingerprint database.

[0042] Wherein, each device attribute data record is composed of a device fingerprint and a plurality of attribute information corresponding to the device fingerprint, and each attribute information is composed of an attribute and an attribute value corresponding to the attribute.

[0043] In the embodiment of the present invention, the similarity of devices is for devices with the same operating system type. At present, the operating system types of devices can be roughly divided into: IOS operating system, Android operating system, Windows operating system, For the Windows Phone operating sys...

Abstract

The invention discloses a method and an apparatus for determining a device fingerprint according to similarity, a server and a computer storage medium. According to the method for determining the device fingerprint according to the similarity, provided by an embodiment of the invention, a first weight value of each attribute is calculated by utilizing a characteristic weight calculation algorithm or a weight model algorithm according to device attribute data records, and the weight value of a weight is not set by depending on human experience, so that the dependency on the human experience is avoided, the accuracy of device similarity calculation is effectively improved, and the accuracy of judging whether devices are same or not is improved; and the calculated weight value is verified, so that the accuracy of the device similarity calculation can be further improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device, server and computer storage medium for determining device fingerprints based on similarity. Background technique [0002] Now many websites hope to analyze user behavior based on the corresponding information of users to achieve the purpose of anti-fraud or precision marketing, especially some banks or e-commerce companies involved in transactions need to determine whether the user's login device has changed. Specifically, it can be solved by device fingerprinting technology, wherein a device fingerprint refers to a non-repetitive and unique device identification generated based on various attribute information of the device, and is the "ID card" of the device in the virtual space. [0003] The core of device fingerprint technology is the judgment of device similarity. In the prior art, the following two methods are used to determine device similarity: [000...
