All Internet, landline and mobile phone users in the Tibet Autonomous Region have provided service operators with their real names, as required by a 2011 local regulation, the regional communications administration said Monday.

By the end of 2012, 2.76 million landline and mobile phone users and 1.47 million Web users in Tibet had registered for services under their real identities, said the administration.

The real-name registration is conducive to protecting citizens' personal information and curbing the spread of detrimental information, said Nyima Doje, deputy director of the administration. In November 2011, the regional real-name regulation was passed.

"Real-name registration will help resolve problems, including the rampant circulation of online rumors, pornography and spam messages, while benefiting the long-term, sound development of the Internet," said Dai Jianguo, member of the legal affairs commission under the regional people's congress.

Nyima Doje said since the registration rules were implemented, the number of spam messages sent via the Internet and phones in Tibet has declined by more than 40 percent.
