Problems solved by technology

These positioning databases mainly use the distribution information of CNNIC (China Internet Network Information Center, China Internet Network Information Center), the IP address deployment information of operators, and the IP information actively fed back by users, and are obtained through applications or refer to other IP address positioning databases, etc. There are many problems such as different data acquisition interfaces, different data presentation forms, different positioning accuracy, asynchronous update speed, inconsistent positioning between databases, etc., resulting in the inability to objectively and accurately evaluate the credibility of each positioning database

example

[0061] In order to verify the effectiveness of the present invention, we use five mainstream positioning databases on the Chinese Internet with better positioning effects as the positioning database of the algorithm, including IP2LOCATION, Pure, IP138, Sina and Taobao.

[0062] Collect 300 IP addresses identified as Beijing and use them as the original data set for the algorithm. In order to ensure that the location address of the collected IP addresses is determined to be Beijing, we first selected 300 network access points determined to be units in Beijing, including national government agencies, administrative institutions, scientific research institutions, and universities; and then based on the corresponding Domain name reverse analysis to obtain its IP address. In order to ensure the validity of the IP address, it is verified based on the IP address filing database of China Internet Network Information Center CNNIC; for the missing IP address items in the filing database...

Abstract

The invention provides an IP positioning database credibility evaluation method based on a dynamic trust model. The method comprises the steps that (1) the consistency of an IP positioning database is analyzed based on the geographical location attribute value; (2) based on the consistency of the current behavior and historical behavior of the IP positioning database, the direct credibility is determined; (3) the indirect credibility of the IP positioning database is determined based on the recommendation credibility of a third-party entity; and (4) the comprehensive credibility is determined based on the direct credibility and the indirect credibility of the IP positioning database. According to the invention, relative objective credibility evaluation of the current domestic mainstream IP positioning database is realized at the provincial level by quantifying the credibility evaluation of the IP positioning database into a dynamic trust model.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for evaluating the credibility of an IP positioning database based on a dynamic trust model. Background technique [0002] IP location databases are widely used to map IP addresses of network devices to physical locations. However, due to problems such as errors in geographic location attribute values ​​and untimely updates in the positioning database, it cannot provide accurate positioning information for some IP addresses, which affects the credibility of the positioning database. [0003] At present, the mainstream databases with better positioning effects on the Chinese Internet include IP2LOCATION, Pure, IP138, Sina and Taobao. These positioning databases mainly use the distribution information of CNNIC (China Internet Network Information Center, China Internet Network Information Center), the IP address deployment information of operators, and th...
