A method for user authentication according to one embodiment of the present disclosure includes acquiring authentication information including biometric information of a user, generating a random string and a helper string from the biometric information, generating a secret value that corresponds to the authentication information, generating a private key and a public key using the secret value and the random string, and transmitting the public key to an authentication server.

Method and apparatus for user authentication

A photocatalyst filter is provided. The photocatalyst filter includes: a base in which an internal space is formed. The internal space is permeable to fluid, and a plurality of photocatalyst beads are provided in the internal space, wherein a surface of the internal space is reflective.

Photocatalyst filter and air conditioner including the same

An air conditioning device is disclosed. The present air conditioning device comprises: a photocatalytic filter including a space through which air can pass and having a transition metal oxide formed in a nanotube form on the surface thereof, the transition metal oxide removing gases included in the air and including at least one of TiO, ZnO, NiO, and WO; and a light source for emitting light to the photocatalytic filter.

Photocatalytic filter and air conditioning device comprising photocatalytic filter

Disclosed is a method for manufacturing a photocatalytic filter for air purification. The present manufacturing method comprises the steps of: oxidizing a titanium metal to obtain a nanostructured titanium dioxide (TiO2); adding the nanostructured titanium dioxide to an acidic fluorine-containing solution to allow a reaction to occur therebetween for a predetermined period of time; and, after treatment in the acidic fluorine-containing solution, performing heat treatment on the nanostructured titanium dioxide.

Method for manufacturing photocatalytic filter for air purification

Disclosed is a method for producing a photocatalyst for air cleaning. The present production method comprises the steps of: preparing titanium dioxide (TiO); attaching platinum to a surface of the titanium dioxide; and attaching fluoro to the platinum-attached surface of the titanium dioxide to obtain surface-modified titanium dioxide.

Method for producing photocatalyst and photocatalyst filter for air cleaning

A system for providing banking services by use of a mobile communication system, in which a variety of financial transactions including inquiry of at least one financial account of at least one financial institution, transfer and remittance, and loan and its interest payment are processed by the mobile communication system. The system includes: the mobile communication system, provided with an integrated circuit (IC) card and a memory device to which a banking application is installed, for transmitting and receiving data by wireless, the IC card being stored with information on a personal identification number (PIN) and information related to financial accounts including a loan account. The banking application processing the financial transactions including the financial account inquiry, the transfer and remittance, and the loan and its interest payment by mobile banking; a base station transceiver system (BTS) for executing a wireless interface with the mobile communication system and a base station controller (BSC) for performing call processing and for providing a core network interface with the BTS. A packet data switching network (PDSN) for providing a packet data transfer service using a transmission control protocol/Internet protocol (TCP/IP); and at least one banking server for, when being requested to process the financial transactions including the financial transactions including the financial account inquiry, the transfer and remittance, and the loan and its interest payment by the banking application of the mobile communication system.

System for providing banking services by use of mobile communication

A method of providing banking services by use of a mobile communication system having a removable built-in integrated circuit (IC) card chip in which personal identification number (PIN) information and related information on financial accounts of a user are stored. The method includes selecting an electronic bankbook service and selecting any one from financial transactions for the electronic bankbook service and comparing the PIN information input at the mobile communication system with the PIN information stored in the IC card chip, and authenticating access to data stored in the IC card chip on the mobile communication system. The method further includes displaying financial account information of the user stored in the IC card chip in a display window of the mobile communication system and forming a financial transaction request message using the related information of the selected financial account through a banking application built in the mobile communication system, and transmitting the financial transaction request message to the banking server. The method further includes performing a predetermined customer authentication process with respect to the financial transactions and financial accounts at the banking server, and transmitting a financial transaction response message to the mobile communication system and displaying the resulting transaction history in the display window of the mobile communication system.
