(Telecompaper) China has tightened regulations for mobile app developers. Rules now require real-name registration and preserving users' activity logs, Reuters reports, citing internet regulator Cyberspace Administration of China (CAC). The watchdog says mobile app providers would need to comply with 6 requirements to help reduce "unscrupulous" use of their platforms to carry out fraud, distribute pornography and spread malicious rumors. "A small number of apps have been exploited by criminal types to spread violence and terrorism, pornographic material, rumors and other illegal information", the regulator said.
