NemID (literally: EasyID) is a common log-in solution for Danish Internet banks, government websites and some other private companies. NemID is managed by the DanID company and came into use on July 1, 2010. Everyone in Denmark who is over 15 years old and has a CPR-Number is eligible for a NemID that can be used with their bank as well as public institutions. Anyone over 13 years old may use a NemID for internet banking. Users of NemID are assigned a unique ID number that can be used as a username in addition to their CPR-Number or a user-defined username. Users receive a card containing pairs of numbers, similar to Transaction authentication numbers. After logging in with a username and password, NemID users are prompted to enter a key corresponding to a number as part of NemID's two-factor authentication scheme. These private keys are one time use only. After all of them are used the user must get new private keys, which are generally sent to the user via mail once they're about to run out. Private keys are kept in a central server. This has caused criticism against the security of NemID system. On 11 April 2013, the NemID system shut itself down in response to a DDoS attack, causing widespread chaos in Denmark where internet banking was not possible during the attack.〔(【引用サイトリンク】url=http://cphpost.dk/national/nemid-system-attack )〕 With Java version 1.7.0_45, NemID Java applet was not able to log users in.〔http://www.b.dk/tech/nemid-dur-ikke-med-seneste-opdatering〕 == See also == * Digital signature – Net-ID 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「NemID」の詳細全文を読む スポンサード リンク
