TriGen is a 64GByte USB thumb drive which is secured by quantum random number generation technology to protect external leakage of enterprise information. A micro quantum random number generator (QRNG) is deployed inside, and users must register personal information to use the memory of TriGen. When TriGen is installed into the user’s Laptop, QRNG generates random numbers as the authentication and delivers it to the registered user’s smart phone. After authentication, memory in TriGen will be activated and available. All activities such as copy, delete, modify, etc., will be monitored by the server. If user violates security policy, connection between the laptop and TriGen will be disconnected to prevent external information leakage.
