Abstract

An approach is disclosed that transmits, from a transmitting device, a wipe instruction to a target device. Execution of the wipe instruction erases a data from the target device. After transmission of the wipe instruction, the approach monitors the target device to gather post-wipe instruction data from the target device. The post-wipe instruction data includes connectivity data detected from the target device. The post-wipe instruction data is analyzed with the analysis determining whether the wipe instruction executed successfully on the target device.

First claim

What is claimed is:

1. A method comprising:
transmitting, from a transmitting device, a wipe instruction to a target device, wherein execution of the wipe instruction erases a plurality of data from the target device;
after transmission of the wipe instruction, monitoring the target device during execution of the wipe instruction, wherein the monitoring gathers post-wipe instruction data from the target device, wherein the gathered post-wipe instruction data includes a set of connectivity data detected from the target device and timing data corresponding to the connectivity data;
analyzing the gathered post-wipe instruction data, wherein the analyzing comprises comparing the gathered post-wipe instruction data to a set of expected post-wipe instruction data for the target device; and
based on the analysis, determining whether the wipe instruction executed successfully on the target device.

2. The method of claim 1 wherein the gathered post-wipe instruction data further includes audible sound data emanating from a speaker of the target device captured by a microphone of a monitoring device that is performing the monitoring.

3. The method of claim 1 wherein the gathered post-wipe instruction data further includes visual data displayed on a display screen of the target device captured by a digital camera of a monitoring device that is performing the monitoring.

4. The method of claim 1 wherein the wipe instruction is intended to restore the target device to a known state.

5. The method of claim 1 further comprising:
sending the wipe instruction from an initiating device to one or more intermediate devices, wherein the initiating device is disconnected from the target device, and wherein one of the intermediate devices is the transmitting device that transmits the wipe instruction to the target device.

6. The method of claim 5 further comprising:
gathering the post-wipe instruction data by the transmitting device; and
sending the gathered post-wipe instruction data from one or more of the intermediate devices back to the initiating device, wherein the analysis is performed after the gathered post-wipe instruction data has been received at the initiating device.

7. The method of claim 6 further comprising:
identifying a device type corresponding to the target device;
retrieving the set of expected post-wipe instruction data corresponding to the device type; and
generating, based on the comparing, a confidence value that indicates a confidence level that the target device was successfully wiped.

8. An information handling system comprising:
one or more 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:
transmitting, from a transmitting device, a wipe instruction to a target device, wherein execution of the wipe instruction erases a plurality of data from the target device and is intended to restore the target device to a known state;
after transmission of the wipe instruction, monitoring the target device during execution of the wipe instruction, wherein the monitoring gathers post-wipe instruction data from the target device, wherein the gathered post-wipe instruction data includes a set of connectivity data detected from the target device and timing data corresponding to the connectivity data;
analyzing the gathered post-wipe instruction data, wherein the analyzing comprises comparing the gathered post-wipe instruction data to a set of expected post-wipe instruction data for the target device; and
based on the analysis, determining whether the wipe instruction executed successfully on the target device.

9. The information handling system of claim 8 wherein the gathered post-wipe instruction data further includes audible sound data emanating from a speaker of the target device captured by a microphone of a monitoring device that is performing the monitoring.

10. The information handling system of claim 8 wherein the gathered post-wipe instruction data further includes visual data displayed on a display screen of the target device captured by a digital camera of a monitoring device that is performing the monitoring.

11. The information handling system of claim 8 wherein the wipe instruction is intended to restore the target device to a known state.

12. The information handling system of claim 8 wherein the actions further comprise:
sending the wipe instruction from an initiating device to one or more intermediate devices, wherein the initiating device is disconnected from the target device, and wherein one of the intermediate devices is the transmitting device that transmits the wipe instruction to the target device.

13. The information handling system of claim 12 wherein the actions further comprise:
gathering the post-wipe instruction data by the transmitting device;
sending the gathered post-wipe instruction data from one or more of the intermediate devices back to the initiating device, wherein the analysis is performed after the gathered post-wipe instruction data has been received at the initiating device.

14. The information handling system of claim 13 wherein the actions further comprise:
identifying a device type corresponding to the target device;
retrieving the set of expected post-wipe instruction data corresponding to the device type; and
generating, based on the comparing, a confidence value that indicates a confidence level that the target device was successfully wiped.

15. A computer program product comprising:
a computer readable storage medium comprising a set of computer instructions, the computer instructions effective to perform actions comprising:
transmitting, from a transmitting device, a wipe instruction to a target device, wherein execution of the wipe instruction erases a plurality of data from the target device and is intended to restore the target device to a known state;
after transmission of the wipe instruction, monitoring the target device during execution of the wipe instruction, wherein the monitoring gathers post-wipe instruction data from the target device, wherein the gathered post-wipe instruction data includes a set of connectivity data detected from the target device and timing data corresponding to the connectivity data;
analyzing the gathered post-wipe instruction data, wherein the analyzing comprises comparing the gathered post-wipe instruction data to a set of expected post-wipe instruction data for the target device; and
based on the analysis, determining whether the wipe instruction executed successfully on the target device.

16. The computer program product of claim 15 wherein the gathered post-wipe instruction data further includes audible sound data emanating from a speaker of the target device captured by a microphone of a monitoring device that is performing the monitoring.

17. The computer program product of claim 15 wherein the wipe instruction is intended to restore the target device to a known state.

18. The computer program product of claim 15 wherein the actions further comprise:
sending the wipe instruction from an initiating device to one or more intermediate devices, wherein the initiating device is disconnected from the target device, and wherein one of the intermediate devices is the transmitting device that transmits the wipe instruction to the target device.

19. The computer program product of claim 18 wherein the actions further comprise:
gathering the post-wip
