  • Patent number: 9652629
    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.

  • Patent number: 8856511
    Abstract: A system and method implemented at a server system, for securely wiping a remote mobile device after the device registration has been removed from the server system. Prior to removal of the device registration from the server system, a “pre-packaged” command is created and stored at the server system. In the event that it is determined, after removal of the registration, that the device should be wiped or disabled, means are provided for an administrator to issue the previously stored command to the target mobile device.
