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 decoding system comprising a server-side proxy component and a back-end computer;

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

a pre-defined rule, load estimates for the back-end computer, estimated network throughputs across network paths to the back-end computer;

wherein said selected back-end computer is configured, responsive to receiving said decoding request, said decoding request comprising an image of decodable indicia, to locate said decodable indicia within said image;

wherein said selected back-end computer is further configured, responsive to successfully locating said decodable indicia, to decode said decodable indicia into a decoded message; and

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.

2. The data decoding system of claim 1, wherein said selected back-end computer is further configured, responsive to successfully decoding said decodable indicia, to transmit said decoded message to said client.

3. The data decoding system of claim 1, wherein said selected back-end computer is further configured, responsive to successfully decoding said decodable indicia, to store in a non-volatile memory at least one or more of:

said image of decodable indicia and said decoded message.

4. The data decoding system of claim 3, wherein said selected back-end computer is further configured, to grant access to at least one of:

said image of decodable indicia and said decoded message upon receipt of security credentials.

5. The data decoding system of claim 1, wherein said selected back-end computer is further configured, responsive to successfully decoding said decodable indicia, to formulate a query containing said decoded message;

wherein said selected back-end computer is further configured, responsive to successfully decoding said decodable indicia, to transmit said query to an external database; and

wherein said selected back-end computer is further configured, responsive to receiving a response to said query from said external database, to transmit said response to said client.
