TikTok, a Chinese video-sharing company, held an event last month to give money to friends when they invite them.



By the way, did you check the fact that the privacy policy has been changed to 'You can collect voices and faces'?



If you invite a friend, it's 12,000 won, and if you invite up to 5 people, it's 400,000 won.



This is a cash reward event held by TikTok last month.



As long as the invited new subscribers enter the code number of the existing subscribers as a referrer, both can receive points, and the points can be exchanged for cash through the simple payment service.



There are a lot of articles online looking for recommenders.



I went directly to one of the open chat rooms.



[Recommended purchase open kakaotalk manager A: (Why did you create a chat room?) I started because I was a student, so my pocket money was limited. A lot of my friends do it too. (Is there any reason to ask for recommenders by giving them money?) Points accumulate several times as the number of recommenders increases, so it is a business that remains even if you give money or condolences (cultural gift vouchers). (Other apps often hold events like this, so why TikTok?) TikTok gives the most money.]



Actually, this kind of compensation seems worth participating, but there is a problem.



Since last July, TikTok changed its privacy policy to 'collect individual characteristics of voices and photos of faces'.



If you do not agree to this, you cannot even sign up at all.



In the past, TikTok has consistently raised controversy regarding the handling of personal information.



Experts are concerned that this time the problem is serious.



[Kim Myung-joo/Professor, Department of Information Security, Seoul Women's University: If you take a specific person's voice and face, you can create artificial intelligence. For example, if you do voice phishing, you can call (to an acquaintance) with the same voice as me. You can even send money by recognizing your face. For example, when sending money through KakaoTalk, what if you hold my face in the face recognition stage (on TikTok) and then pop it up? Then the money goes out of my account. This is a very serious problem.]



If you look at TikTok's privacy policy, it says that 'personal information is shared with other companies'.



If voice and face information is leaked, the risk of misuse of personal information becomes more severe than before.



In the long run, another problem may arise.



[Lim Jong-in / Dean, Graduate School of Information Security, Korea University: China's Personal Information Protection Act or National Security Act, or Big Tech companies, 'Collect personal information and submit it to the state'. Well, do it this way.]



[Myung-Joo Kim/Professor, Department of Information Security, Seoul Women's University: Now, the scope of the (surveillance) is expanded to the whole world, not your own country. (Worldwide) monitoring of people.]



Recently, as regulations on Chinese IT companies have been tightened even more, detailed personal information is being passed on to the Chinese side.



How much and how far is our information flowing in a short moment of a few tens of seconds?
