Abstract

A multiple registration system of using the same account for a user to register different devices to a DRC (digital right certificate) server for further downloading a digital content from the network is disclosed. The system comprises a first device, which includes a first reader and a first device identity code, a second device, which includes a second reader and a second device identity code, and the DRC server. The first device and the second device can build connections with the DRC server through the network. The DRC server is for providing the first or/and the second device to apply an account and to use the same account for further downloading the digital content. During registration, the reader stores the account and an identity code of its own device in its own right record file. When the reader starts retrieving the digital content for reading, in order to prevent illegal copy and distribution, it will check if the right record file has been modified, and check if the identity code in the right record file matches correctly with the device code of the present device in use.

e. the second reader transmitting the UID and the second device identity code to the DRC server, and

f. the DRC server transmitting digital right coupons of all purchased digital contents by the user to the second reader, and the second reader storing the digital right coupons in the second right record file.

7. The method according to claim 6, wherein the method between the step D and step E further comprises:

D1. the second reader asking if the user agrees to transmit the second device identity code to the DRC server;

if yes, proceeding to the step E;

otherwise, ending the method.

8. The method according to claim 6, wherein the method between the step E and step F further comprises:

E1. the DRC server performing examination of registration of the second device.

9. The method according to claim 6, wherein the digital right coupons of all purchased digital contents are for recording expiry date of the UID to use the corresponding digital content and a password of the encrypted digital content, and the digital right coupons are stored in the second right record file.

10. The method according to claim 6, wherein the DRC server further comprises a digital right database for recording the UID, the first device identity code, and the second device identity code.

11. A multiple registration system for a user to use the same account for registering different devices to further order and download a digital content through a network, the system comprising:

a first device, comprising a first reader and a first device identity code; and

a digital right certificate (DRC) server, for providing the first device to apply for the account when the first device builds connection with the DRC server through the network;

wherein the system uses the first reader to encrypt and store the account and the first device identity code in a first right record file, and then to transmit the account and the first device identity code to the DRC server for completing the registration, and when the first reader is initiated, the first reader checks if the first right record file has been changed, and then checks if the first device identity code in the first right record file is correct.

12. The system according to claim 11, wherein when the first reader downloads the digital content, the first reader also downloads a digital right coupon corresponding to the digital content, and the digital right coupon comprises:

a field for an owner identity for recording the UID,;

a field for a serial number of a digital content for recording the unique serial number of the digital content;

a field for allowable times for downloading for recording times for the UID being authorized to download the digital content;

a field for expiry date for recording the expired date of the UID being authorized to use the digital content, and

a field for password of encrypted digital content for recording a password for the first reader to open the digital content;

wherein while the first reader opens the digital content, the first reader firstly checks the digital right coupon if the expiry date of the digital content is overdue according to the filed of the expiry date, and then the first reader retrieves the password from the filed of the password of encrypted digital content in order to open the digital content.

13. The system according to claim 12, wherein the digital right coupon is stored in the first right record file.

14. The system according to claim 11, the system further comprises a second device including a second reader and a second device identity code, enabling the user to register the second device connecting to through the network, wherein the user retrieves the account from the first reader and inputs the account into the second reader, the second reader encrypts and stores the account and the second device identity code in a second right record file and also transmits the account and the second device identity code to the DRC server for completing the registration, and when the second reader is initiated, the second reader checks if the second right record file has been modified, and then check if the second device identity code in the second right record file is correct.
