Abstract

A network resource access system provides network terminals with access to network resources over a network, and includes a resource registry, a driver database, and an authorization server. The resource registry includes resource records associated with the network resources and define at least a resource type for each network resource. The driver database includes resource driver applications for the network resources. The authorization server receives a request from one of the network terminals for communication with one of the network resources, obtains resource configuration data associated with the network resource, and then facilitates communication between the network terminal and the network resource in accordance with a correspondence between the resource configuration data and user configuration data associated with the network terminal.

Claims

1. A network resource access system for providing a network terminal with access to a selected network resource device over a network for communication of translated source data from the network terminal to the network resource device, the system comprising:

a resource registry including resource configuration data associated with the selected network resource device, the resource configuration data including a driver identifier for a resource driver associated with the selected network resource device, the resource driver for translating source data to produce the translated source data in a format suitable for processing by the network resource device; and

an authorization server for receiving a request from the network terminal for communication access to the selected network resource device, the request configured to include a device identifier associated with the selected network resource device and user configuration data associated with the network terminal, the authorization server being configured for determining the network terminal is authorized to access, according to the user configuration data, the selected network resource device associated with the device identifier and for determining the network terminal is configured with the resource driver associated with the driver identifier.

2. The system according to claim 1, wherein the resource configuration data further includes a user access level, and the authorization server is configured to configure the resource driver in accordance with a correspondence between the user configuration data of the network terminal and the user access level associated with the network resource device.

3. The system according to claim 2, wherein the user configuration data includes at least one of a network address associated with the network terminal and a username associated with a user of the network terminal.

4. The system according to claim 3, wherein the authorization server is configured to establish a secure communications channel with the network terminal, and to provide a driver application of the network terminal configured with the resource driver with the respective network terminal address over the secure communications channel.

9. The system of claim 1, wherein the resource configuration data defines a network address associated with the network resource device, and the authorization server is configured to configure a driver application of the network terminal with the respective network address.

10. The system according to claim 1, wherein the network resource device is selected from the group comprising a printer, a facsimile machine, an image server, a file server, an e-mail pager, and an e-mail enabled wireless telephone.

11. The system according to claim 1, wherein the translated source data is selected from the group comprising:

text;

image; and

multimedia data.

12. The system according to claim 9, wherein the network address identifies the Internet Protocol address of a server linking the network resource device to the network.

13. The system according to claim 1, wherein the authorization server compares the driver identifier of the resource configuration data with a driver identifier of an installed resource driver on the network terminal to determine if the network terminal has been configured with the appropriate resource driver of the selected network resource device.

14. The system according to claim 1, wherein the resource driver is selected from the group comprising a generic resource driver and a network resource device specific driver.

20. The system according to claim 12, wherein the network resource device is located behind a firewall and the server is a proxy server located in front of the firewall, the proxy server for facilitating communication of the translated source data across the firewall to the network resource device.

5. A method for providing a network terminal with access to a selected network resource device over a network for communication of translated source data from the network terminal to the network resource device, the method comprising the steps of:

receiving a request from the network terminal for communication access to the selected network resource device, the request including a device identifier associated wit the selected network resource device and user configuration data associated with the network terminal;

obtaining resource configuration data associated with the selected network resource device as identified by the device identifier, the resource configuration data including a driver identifier for a resource driver associated with the network resource device, the resource driver for translating source data to produce the translated source data in a format suitable for processing by the network resource device;

determining the network terminal is authorized to access, according to the user configuration data, the selected network resource device associated with the device identifier; and

determining the network terminal is configured wit the resource driver associated with the driver identifier.

6. The method according to claim 5, wherein the resource configuration data includes a network address associated with the device identifier of the network resource device, and the configuring step comprises configuring a network driver application of the network terminal with the network address.

7. The method according to claim 6, wherein the configuring step comprises the steps of establishing a secure communications channel with the network terminal, and providing the network terminal with the network address over the secure communications channel.

8. The method according to claim 5, wherein the resource configuration data includes a user access level, and the configuring step comprises providing the network terminal with the network address in accordance with a correspondence between the user configuration data of the network terminal and the user access level associated with the network resource device.

15. The method according to claim 5, wherein the network resource device is selected from the group comprising a printer, a facsimile machine, an image server, a file server, an e-mail pager, and an e-mail enabled wireless telephone.

16. The method according to claim 5, wherein the resource driver is selected from the group comprising a generic resource driver and a network resource device specific driver.

17. The method according to claim 5 further comprising the step of comparing the driver identifier of the resource configuration data with a driver identifier of an installed resource driver on the network terminal to determine if the network terminal has been configured with the appropriate resource driver of the selected network resource device.

18. The method according to claim 6, wherein the network address identifies an Internet Protocol address of a server linking the network resource device to the network.

19. The method according to claim 5, wherein the translated source data is selected from the group comprising:

text image; and

multimedia data.
