Security boffins were right after all...Just days after the launch of Japan's computerised national identification system, data has already been muddled up and disseminated to the wrong citizens. Proving the security pundits right in their fears that the resident registry network would go wrong, data was incorrectly sent to around 2,500 people or 741 households in Moriguchi, near Osaka. Letters containing information for verification by individuals were posted out to households. The letters also contained details of other citizen's identification numbers, gender and birth dates. Japanese authorities were not concerned about the hiccup, stating that because the names of people were not included in the wrongly-mailed information it would not cause a problem. Individuals are being given a personal 11-digit identification number to use in online governmental transaction to reduce the Japanese paper-intensive filing system.
