BEIJING - An updated standard for Internet map servers will be implemented next month to avoid State secrets being disclosed and uncertified maps published online, authorities have said.

The new standard issued by the State Bureau of Surveying and Mapping, one year after the first standard was launched, requires all Internet map servers to keep servers storing map data inside the country and provide public Internet protocol addresses.

Under the latest standard, qualified online map servers must have no record of information leakage in any form in the past three years.
