[The Chosun Ilbo, September 22 2008] Google Exposing Thousands of Korean ID Numbers

A query of Excel documents under “residence registration number” on the Internet search engine Google generates some 6,900 results, most of them containing national identification numbers. One search result shows a file containing the ID numbers and mobile phone numbers of the 2006 steering committee of an elementary school in Busan. The document had already been deleted from the school’s website, but the Google search results showed the intact file. Another file showed the names and residence registration numbers of 933 people. The file, apparently medical records, listed even the weight of patients.
