Abstract:
Provided are a zone-based user verification system, a method thereof, and a zone-based user verification server. The zone-based user verification system includes a verification zone setting device configured to set a user verification zone and transmit user verification zone information to a user terminal located near the set user verification zone, a user terminal configured to determine whether the user terminal has entered the user verification zone by using the user verification zone information, and transmit identification information for user verification when it is determined that the user terminal has entered the user verification zone, a service terminal configured to transmit a user verification request signal when it is determined that the user terminal has entered the user verification zone, and a user verification server configured to perform user verification by using information included in the user verification request signal received from the service terminal and identification information for user verification received from the user terminal.
Abstract:
Disclosed are a system for security authentication via a mobile device, which includes: a first terminal of a user which requests mobile authentication; a server which generates authentication information and a key for encryption, encrypts the authentication information with the key, and divides the key into first information and second information to transmit the first information to the first terminal and transmit the second information and the encrypted information to a second terminal of the user; and the second terminal which acquires the first information from the first terminal, generates the key based on the first information and the second information, and acquires the authentication information by using the generated key.
Abstract:
Disclosed are an apparatus and a method for verifying a web site by using a mobile terminal. A method, performed in a server verifying a web site, comprises receiving a message requesting verification on truth or falsehood of a web site which an access terminal accesses from the access terminal; processing the web site based on an Uniform Resource Location (URL) of the web site according to the message; generating verification information for verifying truth of falsehood of the web site based on the URL of the web site, and transmitting the verification information to a mobile terminal; and receiving verification result information on the web site which is generated in the mobile terminal based on an image of the web site and the verification information, and transmitting the verification result information to the access terminal.
