业务风控反欺诈

IP地址是互联网的唯一身份标识，通过分析IP地址地理位置信息与网络接入类型，可以在虚假流量识别、账号安全保障、用户访问安全、爬虫流量屏蔽等方面， 帮助完善风控反欺诈的安全业务模型，有效降低经济损失。匿名流量识别通过分析用户访问网站或者APP的日志记录，利用IP网络接入类型可发现是否是VPN或者代理接入，利用IP定位数据可以发现地域聚集性访问等场景，从而实现匿名流量识别。保障账号使用安全当用户进行登录或在线交易时，使用IP数据服务，可以对用户IP地理位置与授权的GPS位置、表单填充信息进行交叉核验， 判断账号是否存在风险行为，保护用户账号登录、交易、支付等环节的安全。用户访问限制账号隐私泄漏、暴力破解、拖库撞库是常见的网络安全隐患，使用基于IP数据服务的安全策略可以针对访问网站或APP的异常用户IP， 限制规定时间内的访问频次及查询的记录条数，防止大批量数据的抽取。阻止爬虫爬取各类信息著名调查机构Aberdeen Group调查报告显示，整个互联网中，恶意爬虫产生的流量占全网流量的24.1%。爬虫问题会导致网站访问速度缓慢，甚至无法访问。 以IP数据服务为支撑，结合安全策略，可以有效拦截恶意爬虫对于网站内容的爬取，提升网站访问速度。

IP addresses are the unique identifiers for the Internet. By analyzing the geolocation information and network access type of IP addresses, enterprises can optimize their security business models for risk management and anti-fraud across scenarios including false traffic identification, account security guarantee, user access security and crawler traffic blocking, effectively cutting down economic losses.
Anonymous Traffic Identification: By analyzing the log records of users accessing websites or mobile applications (APPs), the network access type of IP addresses can be used to determine whether the access is conducted via VPN or proxy. Meanwhile, IP geolocation data can detect scenarios such as regional aggregated access, thereby enabling anonymous traffic identification.
Account Usage Security Assurance: When users perform login or online transaction operations, the IP data service can be used to cross-verify the user's IP geolocation with the authorized GPS location and form filling information, so as to judge whether the account is engaged in risky behaviors and protect the security of user account login, transaction, payment and other links.
User Access Restriction: Common network security risks include account privacy leakage, brute-force attacks, and database dumping and credential stuffing. Security strategies based on IP data services can restrict the access frequency within a specified period and the number of query records for abnormal user IPs accessing websites or APPs, thereby preventing large-scale data extraction.
Blocking Malicious Crawler Scraping: According to the survey report released by the well-known research institution Aberdeen Group, malicious crawlers account for 24.1% of the total global network traffic. Crawler problems will cause slow website access or even complete unavailability. Supported by IP data services and combined with supporting security strategies, malicious crawler scraping of website content can be effectively blocked, thereby improving website access speed.
