Abstract

The present invention relates to sending control or monitoring information between two hardware devices utilizing email. Control information relating to either a first hardware device or a second hardware device is determined. This information is incorporated into an email message. Directing information for directing the control information is incorporated into the email message. Two hardware devices can then operate cooperatively over different remote networks. These networks only need to be compatible in the ability to exchange email for communication to persist between the two hardware devices. The control information and/or the directing information can be encrypted. The control information and/or the directing information can be encoded. In embodiments of the present invention the encoding map is encrypted.

Claims

1. A method of monitoring over a network a monitored device by a monitoring device using Internet electronic mail, the method comprising:

receiving an electronic mail message by the monitoring device;

extracting, from a field of a header of the received electronic mail message, validation information;

determining, by the monitoring device based on a content of the validation information, whether or not a body of the electronic mail message includes at least one of status and configuration information of the monitored device;

extracting, from the body of the electronic mail message, the at least one of status and configuration information, when the determining step determines that the body of the electronic mail message includes the at least one of status and configuration information, and when the determining step determines that the body of the electronic mail message does not include the at least one of status and configuration information, parsing the body of the electronic mail message without extracting the at least one of status and configuration information; and

storing the extracted at least one of status and configuration information in a memory.

2. The method of claim 1, wherein the validation information comprises at least one of an identification of the monitoring device and a network address of the monitoring device.

3. The method of claim 1, wherein at least one of the validation information and the at least one of status and configuration information are encrypted, the method further comprising:

decrypting at least one of the validation information and the at least one of status and configuration information.

4. The method of claim 3, wherein at least one of the validation information and the at least one of status and configuration information is encoded.

5. The method of claim 4, wherein a map describing the encoding is encrypted.

6. The method of claim 1, wherein the validation information is included in the header of the email message.

7. The method of claim 6, wherein the validation information is included in at least one of the date field, subject field, and comment field of the header.

8. The method of claim 1, wherein the at least one of status and configuration information comprises information related to the configuration of the monitored device.

9. The method of claim 1, wherein the at least one of status and configuration information comprises information related to a status of the monitored device.

10. The method of claim 1, wherein the at least one of status and configuration information comprises instructions for the monitoring device.

23. The method of claim 1, wherein the validation information is encrypted and included in a comment field of the header of the electronic mail message.

11. A monitoring device for monitoring over a network a monitored device using Internet electronic mail, the monitoring device configured to:

receive an electronic mail message by the monitoring device;

extract, from a field of a header of the received electronic mail message validation information;

determine, based on a content of the validation information, whether a body of the electronic mail message includes at least one of status and configuration information of the monitored device;

extract from the body of the electronic message the at least one of status and configuration information, when the monitoring device determines that the body of the electronic mail message includes the at least one of status and configuration information, and when the monitoring device determines that the body of the electronic mail message does not include the at least one of status and configuration information, to parse the body of the electronic mail message without extracting the at least one of status and configuration information; and

store the extracted at least one of status and configuration information in a memory.

12. The device of claim 11, wherein the validation information comprises at least one of an identification of the monitoring device and a network address of the monitoring device.

13. The device of claim 11, wherein at least one of the at least one of status and configuration information and the validation information are encrypted, wherein the monitoring device is configured to:

decrypt at least one of the validation information and the at least one of status and configuration information.

14. The device of claim 13, wherein at least one of the at least one of status and configuration information and the validation information is encoded.

15. The device of claim 14, wherein a map describing the encoding is encrypted.

16. The device of claim 11, wherein the validation information is included in the header of the email message.

17. The device of claim 16, wherein the validation information is included in at least one of the date field, subject field and comment field of the header.

18. The device of claim 11, wherein the at least one of status and configuration information comprises information related to the configuration of either the monitoring device or the monitored device.

19. The device of claim 11, wherein the at least one of status and configuration information comprises information related to a status of either the monitoring device or the monitored device.

20. The device of claim 11, wherein the at least one of status and configuration information comprises instructions for the monitoring device.

24. The monitoring device of claim 11, further configured to extract the validation information from a comment field of the header of the electronic mail message, wherein the validation information is encrypted.

21. A monitoring device for monitoring over a network a monitored device using Internet electronic mail, the monitoring device comprising:

means for receiving an electronic mail message by the monitoring device;

means for extracting, from a field of a header of the received electronic mail message, validation information;

means for determining, based on a content of the validation information, whether a body of the electronic mail message includes at least one of status and configuration information of the monitored device;

means for extracting, from the body of the electronic message, the at least one of status and configuration information, when the means for determining determines that the body of the electronic mail message includes the at least one of status and configuration information, and when the means for determining determines that the body of the electronic mail message does not include the at least one of status and configuration information, for parsing the body of the electronic mail message without extracting the at least one of status and configuration information; and

means for storing the extracted device information in a memory.

22. A computer program product embodied on one or more storage media, the computer program product causing a monitoring device to perform the steps of:

receiving an electronic mail message by the monitoring device;

extracting, from a field of a header of the received electronic mail message, validation information;

determining, based on a content of the validation information, whether a body of the electronic mail message includes at least one of status and configuration information of the monitored device;

extracting, from the body of the electronic message, the at least one of status and configuration information, when the determining step determines that the body of the electronic mail message includes the at least one of status and configuration information, and when the determining step determines that the body of the electronic mail message does not include the at least one of status and configuration information, parsing the body of the electronic mail message without extracting the at least one of status and configuration information; and

storing the extracted at least one of status and configuration information in a memory.
