Description

[0001] APPARATUS AND METHOD FOR AUTHENTICATING USING SPEECH RECOGNITION [0002]

The present invention relates to an authentication apparatus and method using voice recognition. More particularly, the present invention relates to an authentication apparatus and method using voice recognition having enhanced security.

Today, with the development of the Internet, various kinds of online services are being provided. Most online service systems authenticate whether a client computer device accessing the system via the Internet is entitled to use the online service.

The most commonly used user authentication method is an authentication method using a user identifier (ID) and a password. When a user subscribes to an online service system, a user identifier and a password are registered, and the user then accesses the corresponding system When the user ID and password are registered, the user is authenticated.

However, the authentication method using the user identifier and the password has a problem that the authentication information (the user identifier and the password) is easily stolen or hacked, and malicious access attempts can not be blocked if the authentication information is exposed.

In the online service system, a variety of personal information is managed. In recent years, real money transactions have been carried out online through internet banking services and online stock trading services. Intangible assets (for example, items in online games, Cyber money, etc.), there is a need for stronger authentication methods for users using the online service system.

According to the request, a one-time authentication key based authentication method using a user's mobile communication terminal is used. This one-time authentication key-based authentication method generally follows the following procedure. First, the online service system confirms the user identifier and the password, and requests the authentication server to authenticate the user. The authentication server sends a text message (SMS) including the disposable authentication key to the mobile communication terminal of the pre-registered user. The online service system receives the disposable authentication key through the user's computer device and delivers it to the authentication server. Then, the authentication server verifies whether the one-time authentication key sent to the user's mobile communication terminal is the same as the one-time authentication key inputted through the online service system.

Although the one-time authentication key based authentication method can enhance the security strength of the authentication of the user to some extent, there is still a problem that various vulnerabilities due to various hacks exist. Also, there is a problem that resources of the online service system are unjustly occupied by multiple logins by sharing one user identifier and a password with a plurality of acquaintances.
