A service identifying and processing method using a wireless terminal message according to an exemplary embodiment of the present invention includes (a) receiving a wireless terminal message by a first entity which is a mobile device; and (b) expressing, by a first agent which is an information processing application program installed on the first entity, entity information of second entity based on the wireless terminal message and service confirmation information related to service provided by the second entity, through an application screen by the first agent.

Service identifying and processing method using low distance wireless terminal message

Provided is a computer implemented method for performing mutual authentication between an online service server and a service user, including: (a) generating, by an authentication server, a server inspection OTP; (b) generating, by an OTP generator, a verification OTP having the same condition as the server inspection OTP and using the same generation key as an OTP generation key and a calculation condition different from a calculation condition is applied or a generation key different from the OTP generation key is used and the same calculation condition as the calculation condition used for generating the server inspection OTP is applied to generate a user OTP; and (c) generating, by the authentication server, a corresponding OTP having the same condition as the user OTP and comparing whether the generated corresponding OTP and the user OTP match each other to authenticate the service user.

Authentication method and system

Provided is a system for blocking a phishing attack including: a phishing attack prevention storage device; wherein a user terminal or a service server is connected with the phishing attack prevention storage device via a network, wherein a storage area in the phishing attack prevention storage device is mounted in a network drive at the user terminal or the service server, wherein when there is an open request for a real file stored in the storage area in the phishing attack prevention storage device from the user terminal or the service server, the phishing attack prevention storage device checks a storage operation mode and creates a fake file other than the open-requested original file when the storage operation mode corresponds to a list-only mode to return the fake file to the user terminal or the service server via the network.

Anti-phishing system

Provided is a system for blocking a phishing attack including a phishing attack prevention storage device, and an agent program which is installed in a user terminal or a service server and performs an interworking operation with the phishing attack prevention storage device when the user terminal or the service server is connected with the phishing attack prevention storage device via a network. According to the embodiment of the present invention, when there is an open request for the file stored in the phishing attack prevention storage device from the user terminal or the service server, the phishing attack prevention storage device may check a storage operation mode and create a fake file other than the open-requested original file when the storage operation mode corresponds to a list-only mode to return the fake file to the user terminal or the service server.

Disclosed is an authentication management system including a custom credential provider installed on a computing device to support OS account authentication through an alternate authentication method that replaces an OS account authentication method supported by an operating system of the computing device, and an authentication management server communicably connected to the custom credential provider via a communication network to perform user authentication related to a user who attempts to OS account authentication using the alternate authentication information when the OS account authentication based on the alternate authentication information used in the alternate authentication method is attempted and transfer, to the custom credential provider, account authentication information necessary to perform OS account authentication according to the OS account authentication method supporting by the operating system or a seed value that is based on generation of the account authentication information when the user authentication is successful.

Authentication management method and system

Provided is a system for blocking an external attack, which includes: a network file server; and a network file server (NFS) client installed in a user terminal or a service server and communication-connected with the network file server which is remotely positioned, and the network file server determines, when there is an access or opening request of a file stored in the network file server mounted in the user terminal or service server in a network drive format from the NFS client, whether at least one of the user information and the program information to request the access or opening is authorized and blocks the access to the file which is requested to be accessed or provides the file of which opening is requested to the NFS client only in a read only mode when the access or opening request is unauthorized according to a determination result.

Method and system for blocking phishing or ransomware attack

Provided is an authentication system including: a device authentication agent installed in an Internet of things (IoT) device with a communication module and generating first device authentication information for authenticating the corresponding IoT device; an authentication server connected with the IoT device through wired or wireless communication and generating second device authentication information for authenticating the IoT device; and a mobile agent installed in a mobile device of a user, connected with the IoT device and the authentication server through the wireless communication, and verifying whether the IoT device or a message determined to be received from the IoT device is authentic according to whether the first device authentication information transmitted from the IoT device and the second device authentication information transmitted from the authentication server coincide with each other.

Method and system for authenticating IoT device using mobile device

The present invention relates to a method for, when using security software which allows documents to be utilized in PCs and terminals in companies or institutions but not to be leaked therefrom, enabling members to view, generate, edit and delete work files that are generated in the course of business in only secure areas and to freely view, generate and edit non-business personal documents with the same PCs and the same editing software in non-secure areas. More specifically, the present invention relates to a method for, when a program enabling access to a certain secure storage space is set to be a security program, allowing the program to be driven only in the secure storage space by pre-copying a temporary work file (cache file), a folder path, a license file, etc. required to drive the program, to a secure storage space; switching so as to recognize the space as a secure area to which the original path that the program uses has been copied; and allowing the program to view, correct, delete and edit documents in only secure storage spaces.

Method and apparatus for access control of application program for secure storage area

An authentication system for providing an authentication service for a user accessing the same through a communication network includes a seed server for managing a user seed value related to each user identification information, a one time password (OTP) generation device provided in a user's mobile terminal, the OTP generation device generating a user OTP by using at least one portion previously defined in an IP address dynamically assigned to the mobile terminal by a mobile communication operator and a user's user seed value, and an authentication server for, if a user authentication request is received, generating an OTP corresponding to the user OTP by using the at least one portion previously defined in the IP address dynamically assigned to the mobile terminal and the user seed value related to the user identification information, and comparing the user OTP with the corresponding OTP, thereby authenticating the user.
