Abstract

The technology provides, in some aspects, methods and systems for securely transmitting data using a machine vision system (e.g., within a pharmaceutical facility). Thus, for example, in one aspect, the technology provides a method that includes the steps of establishing a communications link between a machine vision processor and a remote digital data processor (e.g., a database server, personal computer, etc.); encrypting, on the machine vision processor, (i) at least one network packet containing machine vision data, and (ii) at least one network packet containing non-machine vision data; and sending to the remote digital data processor the encrypted network packets from the machine vision processor.

Claims

1. A computerized method for securely transmitting data using a machine vision system, comprising:

A) establishing a communications link between a machine vision processor and a remote digital data processor;

B) encrypting, on the machine vision processor, (i) at least one network packet containing machine vision data, and (ii) at least one network packet containing non-machine vision data; and

C) sending to the remote digital data processor the encrypted network packets from the machine vision processor.

2. The computerized method of claim 1, further comprising authenticating the machine vision processor as a source of the network packets sent to the remote digital data processor.

3. The computerized method of claim 1, wherein the network packets comprise Internet Protocol (IP) packets.

4. The computerized method of claim 3, wherein the IP packets are encrypted using the Internet Protocol Security (IPSec) protocol suite.

5. The computerized method of claim 3, wherein the encrypting step further includes encrypting both a header and a payload of (i) at least one IP packet containing machine vision data, and (ii) at least one IP packet containing non-machine vision data.

6. The computerized method of claim 1, further comprising capturing an image of an object with an image acquisition device associated with the vision processor, the image comprising at least a portion of the machine vision data in step (B).

7. The computerized method of claim 6, further comprising performing, with the vision processor, a machine vision function on the image, a result of that machine vision function comprising at least a portion of the machine vision data in step (B).

8. The computerized method of claim 7, wherein the machine vision function comprises a function that recognizes patterns in the image, the patterns including any of letters, numbers, symbols, corners, or other discernable features of the object, a result of that function comprising at least a portion of the machine vision data in step (B).

9. The computerized method of claim 1, further comprising receiving, on the machine vision processor, (i) at least one encrypted network packet containing machine vision data, and/or (ii) at least one encrypted network packet containing non-machine vision data.

10. The computerized method of claim 9, further comprising decrypting, on the machine vision processor, the received network packets.

11. The computerized method of claim 10, further comprising authenticating a source of the network packets prior to receiving the packets.

12. The computerized method of claim 10, further comprising the vision processor storing the resulting unencrypted data in an associated memory.

13. A computerized method for inspecting an object using a machine vision system, comprising:

A) providing machine vision data generated by the machine vision system to a machine vision processor, the machine vision data corresponding to an object;

B) establishing a secure communications link between the machine vision processor and a remote digital data processor;

C) encrypting, on the machine vision processor, (i) at least one network packet containing a portion of the machine vision image data, and (ii) at least one network packet containing non-machine vision image data;

D) authenticating the machine vision processor as a source of the encrypted network packets transmitted to the remote digital data processor; and

E) sending to the remote digital data processor via the secure communication link, the encrypted network packets generated by the machine vision processor.

14. The computerized method of claim 13, further comprising decrypting, on the remote digital data processor, the received authenticated network packets.

15. The computerized method of claim 13, wherein the object includes any of (i) a label containing information of the object, and (ii) a container for storing objects.

16. A machine vision system providing secure data transmission, comprising:

A) a machine vision processor in data communication with a remote digital data processor via a network link;

B) a set of one or more security rules;

C) the machine vision processor, based upon the security rules, encrypting the network link including (i) at least one network packet containing machine vision data, and (ii) at least one network packet containing non-machine vision data;

D) the machine vision processor sending the encrypted network packets to the remote digital data processor; and

E) the remote digital data processor, based upon the security rules, (i) authenticating the machine vision processor as an authorized source of communication network transmissions, (ii) receiving the encrypted network packets from the machine vision processor, and (iii) decrypting the network packets.

17. The system of claim 16, further comprising the machine vision processor, based upon the security rules, encrypting both a header and a payload for (i) at least one network packet containing machine vision data, and (ii) at least one network packet containing non-machine vision data.

18. The system of claim 17, further comprising the machine vision processor, based upon the security rules, (i) receiving one or more network packets from the remote digital data processor, at least one of which is encrypted.

19. The system of claim 18, further comprising the machine vision processor, based upon the security rules, authenticating a source of the received network packets as that of the machine vision processor.

20. The system of claim 19, further comprising the machine vision processor, based upon the security rules, decrypting the authenticated network packets.
