Abstract: Currently，portable storage devices are subject to confront with great challenges，especially the information leakage problems.A data ferrying security model is presented to ensure moving data among different regions transparently within a portable storage device and a mechanism to access trusted region is proposed via taking advantage of those ideas from trusted network connect architecture.Meanwhile，a security mechanism combining fingerprint and the authorization of access to a single data file is implemented to enhance the overall security of portable storage devices.
