[0001] METHOD, APPARATUS AND SYSTEM FOR PROVIDING ELECTRONIC TRADING WITHOUT INSTALLATION OF PLUG-IN [0002]

The following embodiments relate to electronic transactions, and a method, apparatus, and system for providing an electronic transaction through interworking between a user's terminals, a service server (electronic transaction server), and a relay server are disclosed.

In various electronic transactions such as Internet banking, online securities trading, and online shopping, a public certificate is used to authenticate a party of a transaction. Certified certificates are becoming an integral part of non-facing online electronic transactions.

In order to use a secure electronic transaction through an authorized certificate, the application program that the user first contacts may be an authorized certificate subscriber program. The authorized certificate subscriber program provides the function of storing the authorized certificate file, the digital signature function, the issuing and updating function of the digital signature key, and the like.

The functions of the public certificate subscriber software can not be fully implemented by the basic functions provided by the web browser. Therefore, the authorized certificate subscriber software is provided in the form of a plug-in. In order to use the public certificate subscriber software in the form of a plug-in, the user may use an ActiveX, a Java applet, an NPRuntime, a browser add-on, or the like, depending on the operating system or the environment of the web browser. on) may be additionally installed in the terminal.

In recent years, as the usage of the authorized certificate in the smartphone environment is increased, an app is provided that enables the use of the authorized certificate even in the banking using the smart phone. These apps can provide the same functionality as the accredited certificate subscriber programs used on personal computers. However, there is still lack of smooth service support in the environment of the smartphone web browser, and active research and development are being carried out related to the use of the app.

In addition, as e-commerce is widely used, accurate, stable and efficient authentication is required for a user who conducts e-commerce.

In particular, as a user of a plurality of terminals, such as a smart phone, a notebook computer, and a personal computer, becomes a general environment, an authentication method utilizing features of terminals is provided.

Therefore, the storage space such as the memory of the portable terminal may be wasted due to the applications for a plurality of services.

Also, in this method, a function of a service server for performing digital signature using a portable terminal should be established for each operating entity of the service. If the existing service does not support digital signatures using mobile terminals, the operator should change and develop the service server supporting digital signatures. This development can be costly.

In addition, in the case where the service server becomes unsafe due to an attack by a hacker, or when the hacker attacks via a push message or an SMS message impersonating a service server, It does not prevent you from connecting to a service server that you do not have.

In addition, when this method is used, there may arise a problem that the original signature data may be leaked as the original data passes through the relay server.

Also, when a service server, not a relay server, relays signature source data, an authentication system must be configured for each service server, and an application for authentication for each service server must be developed.

One embodiment may provide an apparatus and method for performing authentication through an app that operates independently of a service server.
