Embodiment Construction
[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0058] figure 1 It exemplarily shows a schematic flowchart corresponding to a device identification method provided by an embodiment of the present invention, as shown in figure 1 shown, including the following steps:
[0059] Step 101, acquiring static attribute information and dynamic attribute information from the attribute information of the device under test.
[0060] Step 102, searching for a similar device with the same static att...

The invention relates to the technical field of information security, and particularly relates to an equipment identification method and device. The method comprises the following steps: firstly, acquiring static attribute information and dynamic attribute information from attribute information of equipment to be tested; and then searching similar equipment that has the same static attribute information as the equipment to be tested from an equipment information base; and then determining a similarity value between the equipment to be tested and the similar equipment for each similar equipmentaccording to the dynamic attribute information of the equipment to be tested and the dynamic attribute information of the similar equipment; and finally, taking equipment fingerprints of the similarequipment of which the similarity value is greater than a preset threshold as the equipment fingerprints of the equipment to be tested. According to the equipment identification method and device disclosed by the invention, equipment identification can be implemented in the similar equipment with a smaller range and higher accuracy, and thus the equipment identification rate can be effectively improved; and moreover, the attribute information can be taken into account as much as possible, the accuracy of equipment identification can be effectively improved, and thus the equipment can be identified efficiently, rapidly and real-timely.
Description
technical field [0001] The present invention relates to the technical field of information security, in particular to a device identification method and device. Background technique [0002] At present, with the continuous development of Internet technology, people can shop through the Internet without leaving home, which greatly facilitates people's life. However, the risk of fraudulent transactions brought about by online shopping is gradually increasing. In response to this risk, each shopping platform needs to provide a strong security system, such as collecting device fingerprints to ensure that one device can only register for one account. Prevent fraudsters from using the same device for multiple transactions. [0003] The key point in device fingerprint technology is the matching and calculation of similar devices. In the existing technology, one solution is to identify devices through matching and verification of a small amount of feature information, but this solu...
