IPC: G06F21/24
Filed: 2008-01-18
Abstract: A system and method for selectively securing data from unauthorized access on a client device storing a plurality of data types with reference to an authorization level indicated in a command. A command is received at a client device comprising an authorization level indicator. Based on at least one predefined rule, which may be implemented in an IT policy stored at the client device, each of the plurality of data types to be secured is determined, and then the data corresponding to those types is secured. The data may be secured by encrypting and/or deleting the data at the client device. The predefined rules associated with each authorization level may be configured by a user or administrator having an authorization level that exceeds the associated authorization level. The system and method thus provide a method for securing only selected data types, depending on the authorization level of the issuer of the command.
