Green Dam Youth Escort 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. End users, however, are not under mandate to run the software.As of 30 June 2009, the mandatory pre-installation of the Green Dam software on new computers has been delayed to an unknown date. The software will, however, be available for download from 1 July and will be installed on computers in schools and internet cafes from that date.
The software is specifically aimed at restricting online pornography but could be used for other purposes.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. Bryan Zhang, the founder of Jinhui, said that users would not be permitted to see the list, but would have the option of unblocking sites and uninstalling the software. Additional search terms can also be blocked at the owner's discretion.
Sony has found it necessary to install the Green Dam Youth Escort Internet filtering software, with the company now shipping PCs that has the software pre-installed. Acer and other PC manufacturers are expected to follow suit, and will comply with Chinese law requiring the pre-installed web-filtering software. Although it's possible for Dell, Hewlett-Packard and several others to wait for some type of diplomatic intervention, but China has been reluctant to embrace other governments and regulatory bodies trying to interfere within its borders.
