Abstract

A system for enabling the reading on a reader of content stored in an external storage device is disclosed. The reader is a read-only device and has a display, a processor for controlling the operation of the reader, and a port for operative connection of the external storage device. The external storage device has a non-volatile storage and a central processor. The central processor is able to download to the reader the content stored in the non-volatile storage upon a pre-condition being established. The pre-condition is at least one of receipt of a correct encryption key from the reader, and arrival at a start date and time as determined by a real-time clock. The reader, external storage device, and a corresponding method are also disclosed.

Claims

1. A system for enabling the reading on a reader of content stored in an external storage device;

the reader being a read-only device and having a display, a processor for controlling the operation of the reader, a port for operative connection of the external storage device;

the external storage device having a non-volatile storage and a central processor, the central processor being able to download to the reader the content stored in the non-volatile storage upon a pre-condition being established;

the pre-condition being at least one selected from the group consisting of;

receipt of a correct encryption key from the reader, and arrival at a start date and time as determined by a real-time clock.

2. A system as claimed in claim 1, wherein the real-time clock is selected from the group consisting of:

a part of the external storage device, and a part of the reader.

3. A system as claimed in claim 1, wherein the reader has a plurality of controls for controlling the display, the plurality of controls including at least one selected from the group consisting of:

colour, brightness, contrast, on/off, zoom, and cursor;

the reader storing the encryption key and being sent to the external storage device following operative connection of the external storage device and the reader.

5. A system as claimed in claim 1, wherein the central processor stores the start date and time;

the central processor also storing an end date and time, the real-time clock also for determining arrival at the end date and time; and

upon arrival at the end date and time, all downloading ceases and the content is no longer displayed on the reader.

8. A system as claimed in claim 1, wherein the reader further comprises a buffer for smooth downloads and display;

and the external storage device further comprises an encryption module for encrypting and decrypting the content using the encryption key.

16. A reader as claimed in claim 10, wherein the reader is for use in the system of claim 1.

10. A reader the reader being a read-only device and having a display, a processor for controlling the operation of the reader, a port for operative connection of the external storage device;

the reader being able to download to the reader content stored in a non-volatile storage upon a pre-condition being established;

the pre-condition being at least one selected from the group consisting of;

sending of a correct encryption key by the reader to the external storage device, and arrival at a start date and time as determined by a real-time clock.

11. A reader as claimed in claim 10, wherein the real-time clock is selected from the group consisting of:

a part of the external storage device; and

a part of the reader.

13. A reader as claimed in claim 10, wherein the reader has a plurality of controls for controlling the display, the plurality of controls including at least one selected from the group consisting of:

colour, brightness, contrast, on/off, zoom, and cursor, and the reader stores the encryption key and is sent to the external storage device following operative connection of the external storage device and the reader.

15. A reader as claimed in claim 10, wherein the reader further comprises a buffer for smooth downloads and display.

14. (canceled)

17. An external storage device comprising a non-volatile storage and a central processor, the central processor being able to download to a reader content stored in the non-volatile storage upon a pre-condition being established;

the pre-condition being at least one selected from the group consisting of;

receipt of a correct encryption key from the reader, and arrival at a start date and time as determined by a real-time clock.

18. An external storage device as claimed in claim 17, wherein the real-time clock is a part of the external storage device;

and the encryption key is stored in the reader and is sent to the external storage device following operative connection of the external storage device and the reader.

20. An external storage device as claimed in claim 17, wherein the central processor stores the start date and time;

as well as an end date and time, the real-time clock also determining arrival at the end date and time such that upon arrival at the end date and time, all downloading ceases and the content is no longer displayed on the reader.

23. An external storage device as claimed claim 17, wherein the external storage device further comprises an encryption module for encrypting and decrypting the content using the encryption key.

19. (canceled)

21-22. -22. (canceled)

24. A method for enabling the reading on a reader of content stored in an external storage device;

the reader being a read-only device and having a display, a processor for controlling the operation of the reader, a port for operative connection of the external storage device;

the external storage device having a non-volatile storage and a central processor;

the method comprising connecting the external storage device to the reader using the port, and establishing a pre-condition, the central processor being able to download to the reader the content stored in the non-volatile storage upon the pre-condition being established;

the pre-condition being at least one selected from the group consisting of;

receipt of a correct encryption key from the reader, and arrival at a start date and time as determined by a real-time clock.

25. A method as claimed in claim 24, wherein the real-time clock is a part of the external storage device and the encryption key is stored in the reader and is sent to the external storage device following operative connection of the external storage device and the reader.

27. A method as claimed in claim 24, wherein the central processor stores the start date and time as well as an end date and time, the real-time clock also determines arrival at the end date and time such that upon arrival at the end date and time, all downloading ceases and the content is no longer displayed on the reader.
