Abstract

An authentication method for a network connection for a network device is provided. An embedded system is installed in the network connection, and the network device is free from a web browser. First, the network device connects to an authentication server, and an internet access request is sent to the authentication server. An authentication page is retrieved from the authentication server. User authentication data is obtained by an input unit of the network device, and then the user authentication data is filled in corresponding fields of the authentication page. The authentication page is transferred to the authentication server. After, when authentication of the authentication page is successful, the network device connects to the Internet via the authentication server.

filling the user authentication data in corresponding fields of the authentication page;

transferring the authentication page to the authentication server; and

connecting the network device to the Internet via the authentication server when authentication of the authentication page is successful.

2. The authentication method as claimed in claim 1, wherein when the network device is a wireless network device, the authentication method further comprises:

connecting the network device to a wireless access point and obtaining a network address; and

sending the internet access request to the authentication server via the wireless access point.

3. The authentication method as claimed in claim 1, wherein the step of retrieving the authentication page from the authentication server comprises:

determining whether the authentication page has been previously stored in the network device; and

if the authentication page has not been previously stored in the network device, performing an analysis operation to the authentication page.

4. The authentication method as claimed in claim 3, wherein the step of retrieving the authentication page from the authentication server comprises, if the authentication page has been previously stored in the network device, automatically obtaining the authentication page.

5. The authentication method as claimed in claim 3 further comprising:

when the authentication of the authentication page is not successful or when the analysis operation fails, recording the authentication page;

uploading the recorded authentication page to a remote server when the network device successfully connects to the Internet later;

determining whether the uploaded authentication page is an authentication page which previously existed in the remote server;

if the uploaded authentication page is an authentication page which previously existed in the remote server, loading the authentication page which previously existed in the remote server from the remote server; and

if the uploaded authentication page is not an authentication page which previously existed in the remote server, analyzing the uploaded authentication page, and when the network device successfully connects to the Internet later, loading the analyzed authentication page from the remote server.

6. The authentication method as claimed in claim 1, wherein the authentication is a table conforming to a hypertext markup language (HTML) form, and the table comprises a plurality of user authentication fields, and the authentication method further comprises:

filling the user authentication data in the user authentication fields of the authentication page.

7. The authentication method as claimed in claim 1, wherein the step of filling the user authentication data in the corresponding fields of the authentication page comprises:

determining whether a confirmation field of the authentication page links to Java Script;

if the confirmation field links to the Java Script, executing the Java Script and transferring the authentication page to the authentication server; and

if the confirmation field does not link to the Java Script, transferring the authentication page to the authentication server.

8. A network device where an embedded system is installed therein and which is free from a web browser, comprising:

a storage unit for storing a plurality of authentication pages;

a connection unit for connecting the network device to an authentication server and sending an internet access request to the authentication server;

an input unit for obtaining authentication data; and

an authentication unit for retrieving an authentication page from the authentication server, obtaining the authentication data via the input unit, filling the authentication data in corresponding fields of the authentication page, and transferring the authentication page to the authentication server,

wherein when authentication of the authentication page is successful, the connection unit connects the network device to the Internet via the authentication server.

9. The network device as claimed in claim 8, wherein when the network device is a wireless network device, the wireless network device connects to a wireless access point, obtains a network address, and sends the internet access request to the authentication server via the wireless access point.

10. The network device as claimed in claim 8 further comprising an analysis unit, wherein the authentication page determines whether the authentication page has been previously stored in the network device, and if the authentication page has not been previously stored in the network device, the analysis unit performs an analysis operation to the authentication page.

11. The network device as claimed in claim 10, wherein if the authentication page has been previously stored in the network device, the authentication unit automatically obtains the authentication page.

12. The network device as claimed in claim 10,

wherein when the authentication of the authentication page is not successful or when the analysis operation fails, the authentication unit records the authentication page in the storage unit;

wherein when the network device successfully connects to the Internet later, the authentication unit uploads the recorded authentication page to a remote server;

wherein the remote server determines whether the uploaded authentication page is an authentication page which previously existed in the remote server;

wherein if the uploaded authentication page is an authentication page which previously existed in the remote server, the authentication unit loads the authentication page which previously existed in the remote server from the remote server; and

wherein if the uploaded authentication page is not an authentication page which previously existed in the remote server, the remote server analyzes the uploaded authentication page, and when the network device successfully connects to the Internet later, the authentication unit loads the analyzed authentication page from the remote server.

13. The network device as claimed in claim 8, wherein the authentication is a table conforming to a hypertext markup language (HTML) form, the table comprises a plurality of user authentication fields, and the authentication unit fills the user authentication data in the user authentication fields of the authentication page.

14. The network device as claimed in claim 8,

wherein the authentication unit determines whether a confirmation field of the authentication page links to Java Script;

wherein if the confirmation field links to the Java Script, the Java Script is executed, and the authentication page is transferred to the authentication server; and

if the confirmation field does not link to the Java Script, the authentication page is transferred to the authentication server.

15. A network authentication system comprising:

an authentication server;

the Internet; and

a network device where an embedded system is installed and which is free from a web browser,

wherein the network device connects to the authentication server, sends an internet access request to the authentication server, retrieves an authentication page from the authentication server, obtains authentication data, fills the authentication data in corresponding fields of the authentication page, transfers the authentication page to the authentication server, and connects to the Internet via the authentication server when authentication of the authentication page is successful.

16. The network authentication system as claimed in claim 15 further comprising a wireless access point, wherein the wireless network device connects to the wireless access point, obtains a network address, and sends the internet access request to the authentication server via the wireless access point.
