Abstract

Currently there isn't a way for software to detect if a portable device (such as IBM Thinkpad) is secure with a cable lock and will require physical check. With this invention, any software can report if a cable lock is in place. And as a side effect, security level on the device can be adjusted according to environment.

"Smart" portable locking device

The minimal requirement for this invention is to install a micro-switch (or other sensors, such as light sensor) to detect if a cable lock is inserted in the locking hole of the portable device.

In additional, electronic contact(s) can be made with the cable lock and access (optional) electronic data on a microchip which is embedded in the cable lock.

Main Idea

The minimal requirement for this invention is to install a micro-switch (or other sensors, such as light sensor) to detect if a cable lock is inserted in the locking hole of the portable device.

In addition, electronic contact(s) can be made with the cable lock and access (optional) electronic data on a microchip which is embedded in the cable lock.

The minimal requirement is to have a method detecting locking devices inserted (and secured) into the locking hole of the portable device. This can provide basic function for the software to tell if the device is 'semi-portable' (i.e. cable locked) and allow applications to adjust the settings accordingly.

However, the basic design can be easily bypassed by inserting sharp object into the locking hole, therefore it should not be used to change any OS/application security level.

Electronic contact can be included in the locking mechanism (details to follow) and communicate with a lock that is embedded with a microchip. If such a portable device is used with the convention cable lock
(i.e. no embedded microchip) it can act as the basic design.

However if the portable device can communicate with the microchip embedded in the cable lock.
