Abstract
A method and system are disclosed for placing a computer in a safe and secure lock down state from a remote location using a remote command device such as a cellular telephone. The method and system includes optional security provisions before restarting the computer.
Claims17
A method comprising:
- preparing a message at a personal computing system, said message comprising a unique code based on an address of a hardware component associated with the personal computing system and data specifying a desired lockdown command action;
- establishing a communications link between said personal computing system and a cellular telephone;
- uploading said message to said cellular telephone;
- thereafter receiving, at the personal computing system, data comprising said message from the cellular telephone by way of a network;
- and
- locking-down said personal computing system in response to receipt of said message comprising said unique code associated with said personal computing system and said desired lockdown command action:
- said locking-down comprising:
- responsive to the personal computing system receiving said message in a running state, transitioning into a password protected state;
- and
- responsive to the personal computing system receiving said message in a suspended state, awakening the personal computing system and thereafter transitioning to a password protected state.

Apparatus comprising:
- an electronic memory which stores data and executable software code;
- a network interface card that has an address and can detect a message;
- a processor, operatively coupled to said electronic memory and to said network interface card, and that executes said executable software code that:
- prepares and uploads, to a cellular telephone, a message comprising a unique code based on the address and data specifying a desired lockdown command action;
- determines that data comprising said message has been received from said cellular telephone after said message has been prepared and uploaded to the cellular telephone;
- and
- locks-down the apparatus in response to receipt of said message comprising said unique code associated with said network interface card and said desired lockdown command action:
- wherein the apparatus locks-down by:
- responsive to the apparatus receiving said message in a running state, transitioning into a password protected state;
- and
- responsive to the apparatus receiving said message in a suspended state, awakening the apparatus and thereafter transitioning to a password protected state.
8 more elements
A computer-usable memory device having computer readable instructions stored thereon, for execution by a processor, to:
- prepare a message at a personal computing system, said message comprising a unique code based on an address of a hardware component associated with the personal computing system and data specifying desired lockdown command action;
- establish a communications link between said personal computing system and cellular telephone;
- upload said message to said cellular telephone;
- thereafter receive, at the personal computing system, data comprising said message from the cellular telephone by way of a network;
- and
- lock-down said personal computing system in response to receipt of said message comprising said unique code associated with said personal computing system and said desired lockdown command action:
- said lock-down comprising:
- responsive to the personal computing system receiving said message in a running state, transitioning into a password protected state;
- and
- responsive to the personal computing system receiving said message in a suspended state, awakening the personal computing system and thereafter transitioning to a password protected state.
