Measures against police information leakage utilizing automatic encryption and access control software

National Police Agency (NPA) has developed the Automatic Encryption and Access Control Software as an information security measure and has been operating it since 2007. This software works as follows: 1) principally prohibits information from being transferred to removable media; 2) encrypts information automatically when information is transferred to removable media; 3) logs the history of the transfer between PCs and removable media for audit. This software consists of “Management System of Encryption Key” for the management of encryption keys and access rights, and “Automatic Encryption and Access Control Program” for the control of access to removable media. They work together with USB keys (USB dongles) which are used to physically control authorization and rights.
