In the RFID system, the RFID tag 120 may be classified into an active tag and a passive tag according to whether a power supply is built in the RFID system. The active tag transmits and receives data using its own power supply, which uses its own oscillation circuit. The passive tag receives and receives data from the induced current generated by the exchange of electromagnetic energy with the RFID reader. do.

Thus, active tags can be recognized at a much greater distance than passive tags, while passive tags are lighter, less expensive, and have longer operating life than active tags. Passive tags are widely used when long data transfer times are required or when frequent transfers are required, or where there are no restrictions on data storage.

Each of the RFID reader and the RFID tag 120 includes an antenna coil, and when the antenna coil of the RFID reader and the antenna coil of the RFID tag approach, power is supplied from the RFID reader to the RFID tag 120 by a magnetic field formed between both antenna coils. Can be supplied. Alternatively, the RFID tag 120 may include a unique power supply device, and may receive power from the power supply device.

Using the energy of the power supplied in this way, the RFID tag 120 transmits data stored in the memory inside the RFID tag 120 to the RFID reader through the antenna of the RFID tag 120. After receiving the data input from the RFID tag 120, the RFID reader checks whether the received signal is valid by the microcontroller in the RFID reader when the data is processed. As a result of the inspection, the signal determined to be valid is converted into a data signal and transmitted to the host computer, and the host computer can provide a necessary service in comparison with a previously stored database.

The RFID tag 120 communicates with an RFID reader of the terminal 110 and extracts identification information of the terminal 110. In this case, the identification information of the terminal 110 may include a telephone number of the terminal 110, and may further include information about a user of the terminal 110.

The LCD display screen 130 may receive identification information from the RFID tag 120, receive area information from the information providing system 140, and display area information based on the identification information.

The RFID tag 120 may transmit some or all of the local information to the RFID reader of the terminal 110. The terminal 110 may provide the user with the area information received from the RFID tag 120 by displaying it on the screen of the terminal 110.

The communication network 150 provides communication between the terminal 110, the LCD display screen 130, and the information providing system 140.

The communication network 150 may include a wired communication network, a wireless communication network, the Internet based on Transmission Control Protocol / Internet Protocol (TCP / IP), or a wireless Internet. In addition, the communication network 150 may include a network in which different types of networks are mixed. For example, the communication network 150 may refer to a network in which WiBro and Bluetooth networks, which are wireless Internets, are mixed in the same space.

The communication network 150 may include an administrator or a server, which is a means for efficiently managing a communication entity connected to the network. If the communication network 150 is a wireless communication network, the code division multiple access (CDMA) network, Global System for Mobile communications (GSM), WCDMA, CDMA2000, or IMT2000 The concept includes a base station or repeater manufactured or modified to be used in at least one of all communication networks. The server also includes a network management subsystem for managing the communication network 150, a switching control system for connecting the terminal 110 and the communication network 150, and access switching for matching between the communication network 150 and the terminal 110. It is also a concept that includes subsystems.

International Mobile Telecommunication 2000 (IMT2000), which is presented as an example of the communication network 150, is a third generation mobile communication system established as a standard by ITUR. IMT2000 is a CDMA2000 1X, 3X, EVDO (Evolution Data Only), WCDMA (Wideband CDMA), etc. It is a service that can provide a wireless communication service using the IS95C network evolved from the existing IS95A, IS95B network.

IMT2000 is a mobile communication system that aims to implement various application services by combining global direct roaming including personal mobility and service mobility, same call quality as wired telephone, high speed packet data service and wired / wireless network. In addition to improving existing voice and wireless application protocol (WAP) service quality, various multimedia services (MOD, VOD) can be provided at a higher speed.

The Internet based on Transmission Control Protocol / Internet Protocol (TCP / IP) presented as another example of the communication network 150 is a technology related to a protocol for transmitting and receiving packet data. With the spread of the Internet, users can search for various types of information or transmit various data including texts, voices, images, and moving pictures in real time.

The communication network 150 may include a wireless Internet that provides an internet communication service using a wireless communication network. The wireless Internet may be performed in a form of providing an Internet communication service to a mobile communication service subscriber through a wireless communication network in order to provide a communication service that transcends space. The communication network 150 may provide a ubiquitous interface to a user of the terminal 110 through a wireless Internet technology.

The server of the communication network 150 may divide an area into cell units as necessary and manage traffic for the terminal 110 by cell unit. The base station or repeater may be allocated in units of cells and may be managed in units of cells.

The server of the communication network 150 includes a portion that performs a control function that can be efficiently operated a plurality of base stations and repeaters, and controls the interworking function between the mobile communication network, wireline telephone network, mobile data network, etc., code division It is possible to control the handover function between different types of communication networks such as multiple access (Code Division Multiple Access, CDMA), WCDMA or Global System for Mobile communications (GSM).

The server of the communication network 150 performs location registration of the terminal 110. For example, when a call is connected between the terminal 110 and the other terminal, the server temporarily stores subscriber information of the terminal 110 and the other terminal in the visitor location register (VLR). Home Location Register (HLR) may request the location registration of the terminal 110 and the other terminal.

When the RFID reader of the terminal 110 approaches the RFID tag 120, the RFID tag 120 may notify the information providing system 140 of the access of the terminal 110. The information providing system 140 may be a central control system that manages a plurality of RFID tags disposed in a target area of the information guide service. The information providing system 140 may instruct the RFID tag 120 to extract identification information of the terminal 110 by controlling the operation of the RFID tag 120.

When the access of the terminal 110 is notified to the information providing system 140 by the RFID tag 120, the information providing system 140 may determine the current position of the terminal 110 according to the position of the RFID tag 120. have. If the terminal 110 accessed another RFID tag 10 minutes ago and now has access to the RFID tag 120, the information providing system 140 may track the movement path of the terminal 110.

The tracking of the location of the terminal 110 of the information providing system 140 may be performed separately from the tracking of the location of the terminal 110 by the communication network 150, and may be complementary to each other.

Servers (including network managers, base stations and repeaters) that manage mobile communication networks check whether the mobile communication terminal is currently available for call at regular intervals. At this time, the server may obtain the location information of each of the mobile communication terminal. The service using the location information of the mobile communication terminal grasped by the server is called a location based service (LBS), and the location based service has been expanding its use range with wider usability and convenience. The location-based service detects the location of a mobile communication terminal such as a mobile phone and a personal digital assistant (PDA) and provides additional information related to the identified location.

In general, location-based services include requests for rescue, response to crime reports, geographic information systems (GIS) for providing proximity information, traffic information, vehicle navigation and logistics control, and location-based customer relationship management (CRM). Can provide. The location-based service may also be used for a navigation service for guiding route information.

In the conventional location-based service, the method of determining the location of the mobile communication terminal may vary according to the type of mobile communication network and the type of service.

For example, in a CDMA series communication network represented by Code Division Multiple Access (CDMA), a Global Positioning System (GPS) is used for synchronization between base stations. Therefore, the base station is equipped with a GPS, it can be used to estimate the position of the base station nearest to the mobile communication terminal.

In the Global System for Mobile Communication (GPS) system, synchronization between base stations is performed without using GPS for synchronization between base stations. Even in GSM, a mobile terminal can be located at which base station it is closest.

However, the method of estimating the position of the terminal based on the position of these base stations is greatly reduced since the resolution of the position that can be tracked has been reduced. Is used.

The location tracking method also has a problem that, when the terminal equipped with the GPS equipment is located indoors, the satellite is likely to have difficulty in identifying the terminal location.

For this reason, when navigation data, which is a GPS measurement value, is not obtained due to the case where the mobile communication terminal is located indoors, a base station-based or network-based positioning method is additionally used. Meanwhile, the server of the communication network providing the location based service receives the location information measured by the mobile communication terminal through the mobile communication network such as the switching center and then provides the service based on the user's location.

The information providing system 140 may obtain the location information of the terminal 110 from the server of the communication network 150 when the server of the communication network 150 allows. However, since the location information of the terminal 110 may not be detailed, the information providing system 140 may obtain more detailed information about the current location of the terminal 110 through the RFID tag 120.

The information providing system 140 tracks the location of the terminal 110 based on the location of the RFID tag 120 and generates customized local information for the user of the terminal 110 based on the location of the terminal 110. Can be.

For example, if the user of the terminal 110 is a tourist traveling to a tourist destination, it may be assumed that the RFID tag is disposed in each of the scenic spots, exhibition halls, educational institutions, etc. of the tourist destination. In this case, the information providing system 140 may provide the terminal 110 with the most suitable tour guide information based on the location of the terminal 110. The RFID tag 120 may be arranged based on facilities that can be used by a large public such as major scenic spots, exhibition halls, or educational centers of tourist attractions.

When the current location of the terminal 110 is determined, the information providing system 140 may provide detailed information of nearby tourist attractions, stores of nearby areas, accommodations, restaurants, and the like. In this case, if the facility guided by the information providing system 140 is a commercial facility, the commercial facility may be charged for advertising or promotion. For example, it is also possible to charge the specific commercial facility according to the number of times that the information providing system 140 displays the information on the specific commercial facility on the terminal 110.

The information providing system 140 may track the position of the terminal 110 based on the position of the RFID tag 120, and monitor the position change of the user of the terminal 110. Since the information providing system 140 knows the position of the RFID tag 120 in advance, when the terminal 110 approaches the RFID tag 120, the information providing system 140 may know the position of the terminal 110. In addition, the information providing system 140 may store a path traveled by the user of the terminal 110, and may leave a record of where the user of the terminal 110 has visited.

If the user of the terminal 110 is a tourist visiting a travel destination, there is a risk of loss of passport or belongings. At this time, the terminal 110 embedded with the RFID reader may be used in place of the identification card, the information providing system 140 to ensure the safety of the user of the terminal 110 by monitoring the movement path of the user of the terminal 110. Can be.

If the visit schedule of the user of the terminal 110 is input in advance, the information providing system 140 may quickly recognize and cope with the situation when the user of the terminal 110 is in danger.

The information providing system 140 tracks the location of the terminal 110 based on the location of the RFID tag 120, and based on the planned schedule of the user of the terminal 110 and the current location of the terminal 110. The next schedule of the user of can be generated as local information. The RFID tag 120 may receive the next schedule information from the information providing system 140 and transmit the next schedule information to the terminal 110.

The information providing system 140 transmits all or part of the local information to the LCD display screen 130, and the LCD display screen 130 displays the local information so that the user of the terminal 110 can see it.

The information providing system 140 may include an encoding apparatus that performs image encoding on local information to generate image information to be transmitted to the LCD display screen 130. In addition, when the user of the terminal 110 previously inputs the preference information that the user prefers, the information providing system 140 may generate customized region information considering the preference information based on the identification number of the terminal 110.

When the RFID tag 120 of the terminal 110 approaches, the RFID tag 120 may request the information providing system 140 to generate authentication information for access authentication of the terminal 110. The information providing system 140 generates a first authentication key and a second authentication key in response to the request, transmits the first authentication key to the terminal 110 via the communication network 150, and transmits the second authentication key to the RFID. May be sent to tag 120. The first authentication key and the second authentication key may be a bit stream of k bits (k is an integer of 2 or more).

The RFID tag 120 transmits the second authentication key to the RFID reader of the terminal 110, and the terminal 110 cross checks the first authentication key and the second authentication key and passes the identification information to the RFID tag 120. Decide if you want to reduce.

If the terminal 110 cross checks the first authentication key and the second authentication key and there is no error, the authentication is considered to be successful. If authentication is successful, the terminal 110 may transmit identification information to the RFID tag 120.

The information providing system 140 may use a common key shared with the terminal 110 in generating the first authentication key and the second authentication key. The information providing system 140 may generate a second key using the first authentication key and the common key, and the terminal 110 may verify the second key using the first authentication key and the common key.

For example, assume that the common key, the first authentication key, and the second authentication key are all bit streams of k bits. The information providing system 140 may generate a second authentication key by performing an exclusive logical sum operation of the first authentication key and the common key. The terminal 110 may perform an exclusive logical sum operation of the first authentication key and the common key, and determine that the authentication is successful when the operation result is the same as the second authentication key.

In this way, by double-authenticating the access of the RFID tag 120 to the information of the terminal 110, it is possible to prevent the leakage of personal information of the terminal 110. In order to hack such an authentication system, it is necessary to hack RFID communication together with the communication network 150, so that if the keys used for authentication are 32 bits or more in length, the possibility of personal information leakage can be significantly reduced.

The information providing system 140 may generate the first authentication key using a probability distribution of pseudorandom noise (PRN). In this case, the probability that each bit of the first authentication key has a value of 0 is 1/2, and the probability of having a value of 1 is also 1/2. Since the second authentication key will be generated by a combination of the common key and the first authentication key or a specific operation, the probability that each bit of the second authentication key has a value of 0 is also 1/2.

When using authentication keys having a random probability distribution as described above, the possibility of hacking can be significantly reduced.

When the information providing system 140 acquires the user's personal information, the information providing system 140 may also obtain information about a language that the user mainly uses. The information providing system 140 may consider the language of the user in generating local information for the user.

If the user is a tourist from a foreign country, since the user wants to receive the information guide in his or her native language, the information providing system 140 may provide customized information considering the user's convenience as much as possible.
