YY Live officially launched the "Wind Shield" anti-fraud system and has intercepted more than 10 million yuan of risk transactions

"From November last year to now, through the security risk control system, we have helped the defrauded users recover more than 4 million yuan in losses, and more than 10 million people have been intercepted by us through the system's judgment as risk transactions." YY live broadcast security risk control system leader introduction.

In February 2020, the exclusive system of yy live anti-fraud and anti-fraud was put into research and development, and in November, the system completed the second iteration and was officially put into operation. Recently, this system was upgraded again and officially named "Wind Shield".

"'Wind Shield', as the name suggests, is a powerful shield against risks, based on the company's self-developed microservice architecture, combined with distributed caching, real-time computing, big data components, decision computing and container technology, in the yy live broadcast system, built an anti-fraud AI firewall."

In recent years, the incidence of online fraud cases has been high and frequent, seriously infringing on the property safety and legitimate rights and interests of the people, and forming a number of black and gray industrial chains with clear division of labor and strict organization. The development of network black and gray production has opened up barriers between different formats such as telecommunications, networks, payment and settlement, and social software. Internet companies such as short videos, social networking, e-commerce, and live broadcasting are easily exploited by fraudsters.

In June this year, yy live and the police in Changzhou, Jiangsu Province, smashed a criminal gang that used the "one-dollar purchase" of pornographic app members as a gimmick to carry out "dark thunder" fraud, arresting 18 criminal suspects and involving more than 200 victims. The "Wind Shield" played an active role in the entire process of solving the case.

"'Wind Shield' has a very significant personalized advantage, the entire system and the customer complaint system is completely open, once the customer complaint has a new fraud complaint comes in, we immediately according to big data, draw a sensitive user portrait, continue to monitor the risk trend, and effective judgment research information feedback to the police, in the 'one dollar purchase' fraud case, 'Wind Shield' data and information tracking support is indispensable." The person in charge of the yy live security risk control system said.

The essence of the risk control system lies in the risk (control) pre-positioning and timely stop loss, the "Wind Shield" system has a self-built big data analysis platform, which has the ability to model massive user data. It can not only achieve refined management of the transaction process, intercept suspicious accounts, but also establish a suspicious stop payment database to check and restrict or ban the risk accounts in the library. That is to say, once it is listed as a suspicious account by the "Wind Shield", it means that the account has lost its trading ability on the yy platform. Since November last year, the "Wind Shield" system has effectively intercepted 38,460 high-risk accounts and maintained the property security of many users.

From part-time brushing to impersonating customer service, from fake social security to impersonating the public prosecutor's law, from killing pigs to killing chickens, according to incomplete statistics, the current network fraud methods are as many as 6 categories and more than 300 kinds, and they are constantly "innovating". In the face of the cunning means of fraudsters, the "Wind Shield" system has built a complete self-circulation processing mechanism. Through a large number of user behavior analysis and modeling in advance, a user risk profile is established, risk challenges and interceptions are carried out through real-time rule strategies during the event, and risk trends are monitored and the profiles and rules are adjusted through report boards, risk control early warnings, and customer complaint feedback afterwards, so as to complete the full closed loop of risk control before, during and after the event.

"The ideal perfect 'wind shield' system has strong AI capabilities, can dynamically perceive risks, automatically adjust defense strategies, and intelligently fight." Realizing a benign model in which human and intelligence complement each other can more effectively assist users in preventing fraud and anti-fraud, and protecting the property safety of more people. The person in charge of the yy live security risk control system said.

Anti-fraud and anti-fraud is not only the responsibility of yy live to ensure the safety of users' entertainment, but also the mission of building a clear cyberspace. While continuously improving the "wind shield" of the platform's exclusive anti-fraud system, yy Live has continuously upgraded the security precautions and telecommunications fraud handling mechanism within the company, and actively cooperated with public security organs in many parts of the country to severely crack down on online black and gray production and create a safer and clearer network environment.
