Development of highly secure USB memory device by Fujitsu
Leakage of personal as well as corporate confidential information is on the rise so much so for portable storage medium devices such as USB memory devices due to their easy of transporting them from company to home. But portable memory devices are susceptible to theft and can be easily lost or the stored data can be even leaked through file sharing network when viewed from personal PCs at home. Up to now companies have taken certain step to ensure the security of corporate data such as forbidding employees from taking work-related notebook PCs home, or by insisting on thin clients(2) that pass all traffic through controlled servers. But any practical solution needs to function in real-world business environments where there will still be a need to physically transport confidential data. To address this issue Fujitsu has developed a unique USB memory device prototype contains a processor and battery capable of erasing the stored data on it or self destructing the USB device in an event that the USB device has been plugged into an unauthorized PC. The USB memory device can be set up with a policy whereby the data will be automatically deleted after certain number of hours, or it simply be deleted if the USB memory is plugged into an unregistered computer even once. Along with the self-erasing USB memory device, installing the file redirect software on a PC can be used to restrict the copying of data from the USB memory device, forcing it to reside only on the USB memory itself and a specific company server. This can also be used to prohibit confidential data from being sent as an e-mail attachment or from being printed. Since confidential data is prohibited from being written to the hard disk drive of the PC, it prevents data from being stored on PCs or USB memories and later transferred to file-sharing networks, whether by accident or intentionally. Fujitsu is planning to expand application of this technology for practical information centric security measures in preventing data leakage via e-mail as well as other network channels and not just limiting data leakage via lost storage devices or file-sharing plus to address the issue of data leakage through sub-contractor environments as well.
