Abstract

A content providing method and system are disclosed that enable content producers to make a profit by providing contents encrypted by a mobile terminal. The content providing method includes: encrypting, by a mobile terminal, a content and registering the encrypted content in a content providing server; finding, by a communication terminal, the content registered in the content providing server and paying a use fee to use the content; and transmitting a valid authentication key associated with the content to the communication terminal after the payment. Accordingly, since content producers directly encrypt their contents, they can make a profit corresponding to the use of the contents.

Claims

1. A content providing method comprising:

encrypting, by a mobile terminal, a content and registering the encrypted content with a content providing server;

receiving, by the mobile terminal, a request for a valid authentication key associated with the encrypted content from the content providing server after the content providing server receives a user fee from a user; and

transmitting, by the mobile terminal, the valid authentication key to the content providing server.

2. The method of claim 1, wherein the content is a User Created Content (UCC) or a User Generated Content (UGC).

3. The method of claim 2, wherein encrypting a content and registering the encrypted content comprises encrypting the content and generating the valid authentication key and a sample key.

4. The method of claim 3, wherein the sample key is an authentication key permitting decryption of only a part of the content.

5. The method of claim 3, wherein encrypting a content and registering the encrypted content comprises registering the sample key with the content providing server together with the encrypted content.

6. The method of claim 1, wherein the request for a valid authentication key is received by the mobile terminal by way of an SMS or MMS message.

7. The method of claim 1, wherein the user of the mobile terminal receives a payment from the content providing server.

8. A content providing method comprising:

receiving an encrypted content from a mobile terminal;

receiving a user fee from a user of a communication terminal requesting access to the encrypted content;

transmitting a request for a valid authentication key to the mobile terminal;

receiving a valid authentication key associated with the encrypted content from the mobile terminal; and

forwarding the valid authentication key associated with the encrypted content to the communication terminal.

9. The method of claim 8, further comprising transmitting to the second mobile terminal a sample key to access a portion of the encrypted content upon receiving a download request from the second mobile terminal.

10. The method of claim 8, further comprising posting a notice regarding the encrypted content.

11. The method of claim 8, wherein the encrypted content is a User Created Content (UCC) or a User Generated Content (UGC).

12. The method of claim 8, wherein transmitting the request for the valid authentication key to the mobile terminal uses an SMS or MMS message.

13. The method of claim 8, further comprising transmitting a payment to a user of the mobile terminal.

14. A content providing method comprising:

sending, by a communication terminal, a request for a valid authentication key associated with an encrypted content to a content providing server, the encrypted content being encrypted by a mobile terminal;

sending, by the communication terminal, a user fee to the content providing server; and

receiving, by the communication terminal, the valid authentication key associated with an encrypted content from the content providing server.

15. The method of claim 14, further comprising sending, by the communication terminal, a download request for the encrypted content to the content providing server;

and

receiving, by the mobile terminal, a sample key associated with the encrypted content, the sample key allowing access to a portion of the encrypted content.

16. The method of claim 14, wherein the encrypted content is a User Created Content (UCC) or a User Generated Content (UGC).

17. A content providing system comprising:

a mobile terminal encrypting and providing a content, the mobile terminal comprising;

an encryption module encrypting a content and generating a valid authentication key and a sample key; and

a content manager registering the encrypted content and the sample key with a content providing server, and transmitting the valid authentication key to the content providing server in response to a request from the content providing server.

18. The system of claim 17, wherein the content is a User Created Content (UCC).

19. The system of claim 17, wherein the sample key is an authentication key permitting decryption of only a part of the encrypted content.

20. The system of claim 17, wherein the request for the valid authentication key to the mobile terminal using an SMS or MMS message.
