Abstract
An approach is disclosed that optically transmit data from a dedicated mobile device (DMD) to another device. Optically transmitting the data is performed by displaying the data on a display screen included in the DMD. The approach further optically receives data at the DMD. The data is received at a digital camera included in the DMD. Based on the exchanged data, the DMD determines if the DMD and the other device are bound to each other.
Claims17
A method comprising:
- optically transmitting a first set of data from a dedicated mobile device (DMD) to another device, wherein the optically transmitting comprises displaying the first set of data on a display screen included in the DMD;
- optically receiving a second set of data at the DMD, wherein the second set of data is received at a digital camera included in the DMD;
- verifying, based on the first and second sets of data, that the other device and the DMD are bound to each other,
- periodically transmitting data pertaining to an electronic heartbeat to one of a set of one or more telephone numbers, wherein the data includes a set of global positioning data pertaining to the DMD;
- receiving instructional data from one of the set of telephone numbers responsive to the periodic transmissions;
- and
- inhibiting use of the DMD in response to one of the instructional data when a possible threat to the DMD has been detected.
An information handling system that is a dedicated mobile device (DMD), the information handling system comprising:
- one or more processors;
- a display screen accessible by at least one of the processors;
- a digital camera accessible by at least one of the processors;
- a memory coupled to at least one of the processors;
- and
- a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions comprising:
- optically transmitting a first set of data from the DMD to another device, wherein the optically transmitting comprises displaying the first set of data on the DMD's display screen;
- optically receiving a second set of data at the DMD, wherein the second set of data is received at the DMD's digital camera;
- verifying, based on the first and second sets of data, that the other device and the DMD are bound to each other;
- periodically transmitting data pertaining to an electronic heartbeat to one of a set of one or more telephone numbers, wherein the data includes a set of global positioning data pertaining to the DMD;
- receiving instructional data from one of the set of telephone numbers responsive to the periodic transmissions;
- and
- inhibiting use of the DMD in response to one of the instructional data when a possible threat to the DMD has been detected.
A computer program product stored in a computer readable storage medium, comprising computer program code that, when executed by an information handling system, performs actions comprising:
- optically transmitting a first set of data from a dedicated mobile device (DMD) to another device, wherein the optically transmitting comprises displaying the first set of data on a display screen included in the DMD;
- optically receiving a second set of data at the DMD, wherein the second set of data is received at a digital camera included in the DMD;
- verifying, based on the first and second sets of data, that the other device and the DMD are bound to each other;
- periodically transmitting data pertaining to an electronic heartbeat to one of a set of one or more telephone numbers, wherein the data includes a set of global positioning data pertaining to the DMD;
- receiving instructional data from one of the set of telephone numbers responsive to the periodic transmissions;
- and
- inhibiting use of the DMD in response to one of the instructional data when a possible threat to the DMD has been detected.
