Abstract:
1. A method for detecting a network location of a mobile computing device for use in protecting data accessible to the mobile device, the method comprising: setting a plurality of predefined network parameters corresponding to possible locations of a networked environment in which the mobile computing device may be operating; by the mobile computing device, obtaining a set N of actual network parameters corresponding to the networked environment in which the mobile computing device is actually presently operating, the set N of actual network parameters corresponding to the predefined network parameters; setting per each of the possible locations of the networked environment in which the mobile computing device may be operating a minimum subset M of the set N of actual network parameters that may be used to correctly identify the location of the mobile computing device, wherein M≦N, N>3 and M≧2; comparing the obtained said set N of actual network parameters to the plurality of predefined network parameters; and only by the mobile computing device, determining a present location of the mobile computing device based on the comparing such that if the minimum subset M of the set N of actual parameters match a corresponding number of any of the network parameters of the predefined network parameters, concluding the present location of the mobile computing device has been successfully determined, and changing a security policy based on the determined present location; and if the minimum subset M of the set N of actual parameters do not match the corresponding number of the any of the network parameters of the predefined network parameters, concluding the present location of the mobile computing device has not been successfully determined and setting the present location to a default location and a default security policy.
