Green Dam Youth Escort - Wikipedia, the free encyclopedia

Green Dam Youth Escort (simplified Chinese: 绿坝·花季护航; pinyin: Lǜbà·Huājì Hùháng) is content-control software developed in the People's Republic of China (PRC). Under a directive from the Ministry of Industry and Information Technology (MIIT) of the PRC taking effect on 1 July 2009, it is mandatory to have either the software, or its setup files pre-installed on, or shipped on a compact disc with, all personal computers sold in Mainland China, including those imported from abroad.[1][2] End users, however, are not under mandate to run the software. // The software is specifically aimed at restricting online pornography but could be used for other purposes.[4][5] Green Dam Youth Escort automatically downloads the latest updates of a list of prohibited sites from an online database, and also collects private user data.
