Data Loss Prevention Technologies

Although data loss has become an important problem that needs to be solved in many types of organizations, possible routes of data loss have become complicated and numerous, making countermeasures difficult to develop. Fujitsu Laboratories is developing data loss prevention technologies that integrate know-how related to mobile devices, data searching technologies, and security technologies like encryption that have been under development at Fujitsu for some time. These data loss prevention technologies are undergoing verification and testing within the company with an eye towards commercialization. This paper introduces three technologies that will enable information to be used in an expanded workplace with guaranteed safety, without placing a burden on the user. The expanded workplace will extend beyond the borders of a company to include offline work at a customer's office and at other organizations including collaborating companies. The paper begins by introducing a solution for moving data safely outside the company using a novel universal serial bus (USB) memory device. Next, it presents an E-mail filter for preventing the erroneous sending of E-mail containing sensitive information. Finally, it describes document management technology for protecting a document across its entire lifecycle including editing. It also touches upon data loss prevention technologies in the coming era of software as a service (SaaS) and Cloud computing.
