By Lulingzicun The Lunar New Year has arrived, and predicting fortunes for the Year of the Rooster is a popular pastime among young people during their leisure time. Although the act of “fortune-telling” may seem more like a recreational activity, it can boost confidence or provide warnings, effectively “changing fortunes” through psychological suggestion. Interestingly, this … Read more
To distinguish between humans and computers, many services on the Internet use CAPTCHA technology, such as email applications, bank system logins, and transaction confirmations in e-commerce systems. Although character recognition remains the most commonly used method for CAPTCHAs, image semantic recognition-based CAPTCHAs have gradually appeared in some important Internet applications and have sparked heated discussions. … Read more
