LOCATION-BASED DATA SECURITY

摘要

In an example, a system and method are disclosed for location-based security for devices such as portable devices. A portable device may be provided with a short-range transceiver (such as RIFD) that is detectable when a user enters or exits an area. The device may also include an encrypted storage divided into a plurality of discrete units. Upon entering an area, the devices identity and location are provided to a policy server. In response, the policy server may wirelessly provide security tokens to the portable device that enable decryption of specific storage units authorized for access in that area. When a user passes back through a portal to the area, the security tokens are revoked, so that access to secured units of the storage is restricted.
