Method and apparatus for alerting a target that it is subject to sensing and restricting access to sensed content associated with the target
Abstract
A method and apparatus for protecting sensed content and warning a target of sensing is disclosed. A first transceiver, (e.g., a network server), includes a database which defines at least one zone in which sensing a target is not permitted. A second transceiver, (e.g., a cell phone), senses a target to obtain content and temporarily stores the content in a memory, after being encrypted. The cell phone transmits information to the network server which indicates the location of the cell phone. The network server receives the location information from the cell phone and determines whether the target was sensed in a "Do Not Disturb Zone". If so, the network server instructs the cell phone to delete the encrypted content from the memory. Otherwise, the network server indicates to the cell phone that the temporarily stored content may be decrypted, stored in a permanent memory and used as desired.
