Security management system for portable memory devices and security management method using the same

摘要

The present invention relates to a security management system of an auxiliary memory medium and a method for managing security of an auxiliary memory medium using the same, comprising: an auxiliary memory medium having a serial number for authentication; It is embedded in the auxiliary storage medium, and determines whether there is a terminal agent in the user terminal, and if the terminal agent exists, the operating environment of the auxiliary memory medium is determined as the internal use environment, and if not present, the external use environment. A secondary memory medium agent for determining and performing external use authentication by communicating with a management server when the external use environment corresponds to the external use environment; A user terminal to which the auxiliary storage medium is connected; A terminal agent which is executed in the user terminal and performs internal use authentication of the auxiliary storage medium by communicating with a management server when the use environment of the auxiliary storage medium corresponds to internal use; And a management server storing information on the availability of the auxiliary storage medium and transmitting external authentication information or internal authentication information for the auxiliary storage medium.;The present invention as described above has the effect of blocking the leakage of internal information, such as businesses through the secondary storage medium and the unauthorized access to the secondary storage medium to enable the safe use of data by the authorized person.;USB, Memory, Secondary Storage, Security, Authentication, Management
