Coincidentally, the example of collecting palm prints by Humanity today serves as a reminder to protect one's privacy, as some things that may seem insignificant at present may become important/sensitive in the future (especially when you have some money/fame). For example, @ cz-binance had already warned about the development of AI as early as 2022, and the possibility of scammers using Deepfakes to deceive people was reiterated in October last year. The latest news is that on June 20th, a Japanese female blogger had a video conference with a friend disguised as deepfake by hackers and clicked on a phishing link, resulting in heavy losses. This is one of the reasons why I have always disliked exposing my face in public. When your video is easily obtained by attackers, it becomes much easier for them to attack you, your family, and friends with other social engineering information. Think about it, if someone pretends to be a friend in the cryptocurrency circle and calls your social media video chat, not only can they answer your questions in near real-time, but they can even recall some details that were only mentioned in your previous chat with them (stealing your previous chat records). At this point, will you easily believe the link he sends and click on it? And biometric features such as iris, fingerprint, palm print, and vein diagram are even more important in the AI dominated future, because it will become increasingly difficult to distinguish between real people and AI on social networks solely through reading, conversation, and other means (in fact, I can hardly recognize some comments on tweets now). So the story of WLD and Humanity can be hyped up so much because these things are indeed the key to distinguishing between 'human and non-human' in the future. But the problem is that in most blockchain projects, which are only used for making money and have a lifespan of only 3-5 years, you easily hand over the key to opening your own door just for the sake of airdrops. Is it worth it? My early work experience has shown me that many companies' slightly more valuable assets before bankruptcy are often taken away and sold by employees, even by janitors. And many people in China receive harassing and fraudulent phone calls from information collected by various service providers in their daily lives, which are then packaged and sold. In the future, personal biometrics may be bound with more payment/login services, and the risk may be more terrible than the outflow of your phone number/ID number number. I have seen some CEX/wallets where customer information is taken to the dark web for sale after the team goes bankrupt. Otherwise, why would so many people receive accurate scam emails? So until there is a very mature, secure, legally protected, or stronger responsible party, I will never give away my sensitive information (of course, if you are sure that you will not be able to make a fortune in the future, that's another matter) 😂😂）。
