ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method of authenticating and charging a client using a web infoshop service system, wherein the web infoshop service system authenticates and charges a client in place of a content provider when the client uses a charged information service of the content provider.
2. Description of the Prior Art
FIG. 1
illustrates a configuration of a content providing service network in a conventional system. A client computer
101
connects to a charged content provider
105
through a public switched telephone network
102
and a telephone matching equipment
103
. The telephone matching equipment
103
has only a function of converting a telephone network protocol into an internet protocol and has been disclosed in a paper appearing in a collection of papers of a fall general scientific meeting held by Korea Communication Academy on November in 1996 for Design of Open Internet Connection Sub-System and Implementation Thereof.
The client computer
104
is connected to the charged content provider
105
through the internet
106
. In such content providing service network of the conventional system, management and responsibility for the authentication is in the client computers
101
and
104
and the charged content provider
105
, and management for charging is directly processed by the content provider
105
. There is no problem in this conventional system if the number of the charged content providers is small, but the charged content providers are in tend of increase. A basic authentication method provided by a hypertext transfer protocol is a representative authentication method generally used in present, and new methods enhancing security function have been developed and applied.
In the conventional system, since the charged content provider
105
takes charge of the authentication and charging with respect to a web information providing service, clients or users must obtain separate authentication values for different content providers to use the contents provided different charged content providers
105
.
Additionally, when a client uses a charged content provider
105
, the client must enter a unique authentication value (a user identification and a password) determined by the client and the charged content provider
105
. The client must maintain and manage different authentication types and their values to use the information of the different charged content providers, while the charged content provider
105
must separately manage authentication values for different clients and conduct tasks such as calculation of an amount of charge for each client from the amount used, issue of bills, and receipt of charges. Therefore, there is a problem in that the charged content providers are annoyed to perform the management of the authentication and charging besides provision of information which is a basic task of the content provider.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a method of authenticating and charging a client using a web infoshop service system that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
An objective of the present invention is to provide a method of authenticating and charging a client using a web infoshop service system where the web infoshop service system, in place of a charged content provider, authenticates a client and performs charging tasks, such as calculation of an amount of charge, issue of bills, and receipt of charges, with respect to each directory as well as each internet address, the charging being performed by the time as well as volume of data.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, a method of authenticating and charging a client using a web infoshop service system includes the steps of: transmitting protocol address information from the service system to the client when the client accesses the service system and selects a protocol access; when a user request to the service system is for a charged content provider, adding an authentication value to the user request, transmitting the user request including the authentication value from the service system to the charged content provider, and transmitting information corresponding to the user request from the content provider to the client; and when the client cancels the protocol access and notifies cancellation information to the service system, transmitting charging information using the service system.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
