METHOD AND APPARATUS FOR PREVENTING ACCESS TO INFORMATION STORED AT A NODE

摘要

In one implementation of the present invention, a cellular network for wireless communications (e.g. a cellular telephone network) receives a transmission including an identification token from a mobile unit (e.g. a telephone). Via a service provider, the network also receives a command to prevent access to information stored at the mobile unit. Upon detecting a correspondence between the identification token and the command to prevent access to information stored at the mobile unit, the network instructs the mobile unit to prevent access to local information, which information may include a directory of telephone numbers and other personal and/or confidential items.
