Abstract

A method and system for improving secured access to data files stored on a printing device using an authorization device for receiving and transmitting an authorization code to a printing device for the release of secure data. An authorization code associated with secure data stored in a memory of a printing device is transmitted to an authorization device for later transmission to the printing device for the release of the secure data.

Claims

1. A method for authorizing a print job from a printing device, comprising:

sending at least one print job from a computer system to said printing device;

communicating at least one authorization code to an authorization device for releasing said at least one print job from said printing device; and

communicating said at least one authorization code from said authorization device to said printing device for authorizing printing of said at least one print job.

2. The method of claim 1, further comprising printing said at least one print job.

3. The method of claim 1, wherein said printing device is selected from the group consisting of a printer, a copier, and a multifunction device.

4.

5. The method of claim 1, wherein said communicating at least one authorization code to an authorization device for releasing said at least one print job from said printing device comprises:

placing said authorization device in a cradle in communication with said computer system via a cable connection;

initiating communication between said authorization device and said computer system; and

downloading said at least one authorization code to said authorization device.

6. The method of claim 1, wherein said communicating at least one authorization code to an authorization device for releasing said at least one print job from said printing device comprises transmitting said at least one authorization code to said authorization device via a wireless transmission.

7. The method of claim 1, wherein said at least one authorization code comprises an authorization code selected from the group consisting of a password, a personal identification number, a personal identification code, an encrypted key, and a set of encryption keys.

8. The method of claim 6, wherein said communicating said at least one authorization code from said authorization device to said printing device comprises transmitting said at least one authorization code from said authorization device to said printing device via a wireless transmission selected from the group consisting of an infrared transmission and a radio frequency transmission.

9. A method for accessing a data file stored in a printing device, comprising:

associating a unique authorization code to said data file for limiting access to said data file;

saving said data file and said unique authorization code to a storage media associated with said printing device;

saving said unique authorization code to an authorization device; and

transmitting said unique authorization code from said authorization device to said printing device for authorizing access to said data file.

10. The method of claim 9, wherein said saving said data file and said unique authorization code to a storage media associated with said printing device comprises saving said data file and said unique authorization code to a memory associated with said printing device, wherein said memory is selected from the group consisting of random-access memory, flash memory, hard disk memory, optical memory, and read only memory.

11. The method of claim 9, wherein said saving said unique authorization code to an authorization device comprises saving said unique authorization code to a device selected from the group consisting of a personal digital assistant, a cellular phone, a combination cellular phone/personal digital assistant, a pager, a laptop computer, a handheld computer, a calculator, a handheld game device and a watch.

12. The method of claim 9, wherein said saving said unique authorization code to an authorization device comprises:

establishing a communications link between a computer system and said authorization device;

downloading said unique authorization code from said computer system to said authorization device; and

saving said unique authorization code in a memory of said authorization device.

13. The method of claim 9, further comprising creating said data file on a computer system.

14. The method of claim 9, further comprising transmitting said unique authorization code to said authorization device before saving said unique authorization code to said authorization device.

15. The method of claim 14, wherein said transmission of said unique authorization code to said authorization device is accomplished using wire-based transmissions.

16. The method of claim 14, wherein said transmission of said unique authorization code to said authorization device is accomplished using wireless transmissions.

17. The method of claim 14, wherein said transmission of said unique authorization code to said authorization device is accomplished using infrared transmissions.

18. The method of claim 9, wherein said unique authorization code comprises an authorization code selected from the group consisting of a password, a personal identification number, a personal identification code, an encrypted key, and a set of encrypted keys.

19. A system for transmitting authorization codes to a printing device for releasing secure data stored by said printing device, comprising:

a printing device for storing secure data received from a computer system until said secure data is released by at least one authorization code transmitted to said printing device by an authorization device;

a computer system for sending secure data to said printing device for storage and for communicating said at least one authorization code for releasing said secure data from said printing device; and

an authorization device for receiving said at least one authorization code from said computer system and for transmitting said at least one authorization code to said printing device for releasing said secure data.

20. The system of claim 19, wherein said authorization device is selected from the group consisting of a personal digital assistant, a cellular phone, a combination cellular phone/personal digital assistant, a pager, a calculator, a handheld game device, a watch, a laptop computer, and a handheld computer.

21. The system of claim 19, wherein said authorization device comprises:

a memory for storing said at least one authorization code; and

at least one communications device for communicating with said computer system and said printing device.

22. The system of claim 21, wherein said at least one communications device is selected from the group consisting of an infrared communications device, a radio transmission/receiver communications device, a personal digital assistant cradle, and a wire-based communications device.

23. A method for authorizing changes to control settings of a printing device, comprising:

assigning a unique authorization code to said control settings for preventing alterations of said control settings without said unique authorization code;

communicating said unique authorization code to an authorization device; and

transmitting said unique authorization code from said authorization device to said printing device for allowing alteration of said control settings.

24. The method of claim 23, further comprising storing said unique authorization code to a storage device associated with said printing device before communicating said unique authorization code to said authorization device.

25. A computer-readable medium having computer-executable instructions for authorizing a print job from a printing device, said computer-executable instructions for performing acts comprising:

sending at least one print job from a computer system to said printing device;

communicating at least one authorization code to an authorization device for releasing said at least one print job from said printing device; and
