Abstract

A data decoding system that includes a server-side proxy component and at least two back-end computers, where the server-side proxy component is configured, when it receives a decoding request from a client, to select a back-end computer to forward the decoding request to, based on either a pre-defined rule, load estimates for said at least two computers, estimated network throughputs across network paths to the two computers. In response to receiving this request, the back-end computer that is selected is configured to decode the request, which is an image of decodable indicia, by locating the decodable indicia within the image and decoding it into a decoded message. The decodable indicia was provided by a raw image byte stream, a compressed image byte stream, or a partial compressed image byte stream.

Claims

1. A data encoding system comprising a server-side proxy component and at least two back-end computers;

wherein said server-side proxy component is configured, responsive to receiving an encoding request from a client, to select a back-end computer to forward said encoding request to, based on one or more of;

a pre-defined rule, load estimates for said at least two computers, estimated network throughputs across network paths to each of said at least two computers; and

wherein said selected back-end computer is configured, responsive to receiving said encoding request, said encoding request comprising raw data, to encode said encoding request into an image of decodable indicia.

2. The data encoding system of claim 1, wherein said client is provided by an encoded information reading (EIR) terminal comprising an RFID receiver configured to output said encoding request.

3. The data encoding system of claim 1, wherein said selected back-end computer is further configured, responsive to successfully encoding said encoding request into said image of decodable indicia, to transmit said image of decodable indicia to said client

wherein said image of decodable indicia is provided by one or more of:

a raw image byte stream, a compressed image byte stream, a partial compressed image byte stream.

4. The data encoding system of claim 1, wherein said selected back-end computer is further configured, responsive to successfully encoding said encoding request into said image of decodable indicia, to store in a non-volatile memory at least one of:

said image of decodable indicia and said encoding request.

5. The data encoding system of claim 4, wherein said selected back-end computer is further configured, to grant access to at least one of:

said image of decodable indicia and said encoding request upon receipt of security credentials.

6. The data encoding system of claim 1, wherein said image of decodable indicia is provided by one or more of:

a 1D bar code, a 2D bar code, and one or more OCR symbols.

7. The data encoding system of claim 1, wherein said selected back-end computer is further configured, responsive to receiving said encoding request, to authenticate said client.

8. The data encoding system of claim 1, wherein said selected back-end computer is further configured, responsive to receiving said encoding request, to establish a communication session with said client;

and

wherein said communication session is supported using at least one of;

HTTP cookies, dynamic URLs.

9. A method for encoding data, the method comprising the steps of:

a computer receiving a request comprising raw data from a server-side proxy component said server-side proxy component having received said request from a client

wherein said request was routed to said computer based on one or more of;

a pre-defined rule, load estimates for said computer, estimated network throughputs across network paths to said computer; and

said computer encoding said request into an image of decodable indicia

wherein said image of decodable indicia is provided by one or more of;

a 1D bar code, a 2D bar code, and one or more OCR symbols.

10. The method of claim 9, wherein said client is provided by an encoded information reading (EIR) terminal comprising an RFID receiver configured to output said encoding request.

11. The method of claim 9, further comprising:

said computer transmitting said image of decodable indicia to said client

wherein said image of decodable indicia is provided by one or more of;

a raw image byte stream, a compressed image byte stream, a partial compressed image byte stream and

wherein said compressed image byte stream is provided by one or more of;

a TIFF byte stream, a GIF byte stream, a JPEG byte stream, an MPEG byte stream.

12. The method of claim 9, further comprising:

said computer storing said image of decodable indicia.

13. The method of claim 9, further comprising:

said computer authenticating said client responsive to receiving said request;

and said computer initiating a communication session with said client wherein said communication session is supported using at least one of;

HTTP cookies, dynamic URLs.

14. A computer program product for encoding data, the computer program product comprising:

one or more computer-readable, tangible storage devices;

program instructions, stored on at least one or more storage devices, to receive a request comprising raw data from a server-side proxy component said server-side proxy component having received said request from a client

wherein said request was routed to said computer based on one or more of;

a pre-defined rule, load estimates for said computer, estimated network throughputs across network paths to said computer and

wherein said pre-defined rule is provided by one or more of;

round-robin selection rule and random selection rule; and

program instructions, stored on at least one or more storage devices, to encode said request into an image of decodable indicia.

15. The computer program product of claim 14, further comprising:

program instructions, stored on at least one or more storage devices, to transmit said image of decodable indicia to said client.

16. The computer program product of claim 14, further comprising:

program instructions, stored on at least one or more storage devices, to store said image of decodable indicia.

17. The computer program product of claim 14, further comprising:

program instructions, stored on at least one or more storage devices, to grant access to at least one or more of;

said image of decodable indicia and request upon receipt of security credentials.

18. The computer program product of claim 14, wherein said image of decodable indicia is provided by one or more of:

a 1D bar code, a 2D bar code, and one or more OCR symbols.

19. The computer program product of claim 14, further comprising:

program instructions, stored on at least one or more storage devices, to authenticate said client responsive to receiving said request.

20. The computer program product of claim 14, further comprising:

program instructions, stored on at least one or more storage devices, to establish a communication session with said client responsive to receiving said request

wherein said communication session is supported using at least one of;

HTTP cookies, dynamic URLs.
