1 is a view for explaining the configuration of a wireless home network according to the present invention, the wireless home network may include a home appliance and a personal device with a built-in wireless home network system. For example, there is a washing machine, a TV, audio, as well as a refrigerator, a camcorder, a digital camera, a laptop, a PC, an air conditioner, a boiler, a set-top box, a PDA, a mobile phone, a smartphone, and the like.

The wireless home network system includes a fingerprint reader 100, and status information can be known by an indicator such as an LED.

A user inputs his or her fingerprint information to the fingerprint reader 100, and the wireless home network system converts the fingerprint extracted from the fingerprint reader 100 into a basic string to form the basic string into a wireless home network. Can be used as an address.

In this case, the basic string may be used as a Bluetooth address when the wireless home network connection method is Bluetooth, an SSID when the connection method is WLAN, and a PANID when the connection method is Zigbee.

On the other hand, the wireless home network system included in each device extracts a basic string from the fingerprint information received through the fingerprint reader 100 from the user, respectively, as described above using the base string as a unique address to other devices The connection request message may be transmitted, and another device that receives the connection request message may transmit a response message according to whether the basic string matches, and determine whether to connect to the device that transmitted the connection request message.

Subsequently, the wireless home network system may receive a response message and transmit / receive data through the wireless home network system between devices included in the wireless home network to configure a wireless home network.

2 is a diagram illustrating a configuration of the wireless home network system, a biometric scanner unit 201 receiving fingerprint information from a user, a string generator 202 generating a basic string based on the fingerprint information, and A memory unit 203 for storing the basic string, a connection request message having the basic string as a communication address, a communication unit 205 for receiving a response message of another device to the connection request message, and the response; The controller 204 may be configured to determine whether or not the basic string included in the message matches the basic string stored in the memory unit and to perform a wireless connection with the other device using the basic string as a temporary address.

As described above, the biometric scanner unit 201 scans a user's fingerprint to generate fingerprint information and transmits the fingerprint information to the string generator 202, and the string generator 202 is based on the fingerprint information. You can create a string.

Thereafter, the controller 204 uses the basic string as a unique address for connection with the wireless home network system included in the other device, and a unique channel for data exchange between devices configuring the wireless home network through the communication unit. To form. Accordingly, the hooking of the exchanged data can be prevented by blocking the connection of other users through the creation of the unique channel.

In addition, when the communication method of the wireless home network is Bluetooth, the basic string is used as a Bluetooth address, when the wireless connection is a wireless LAN, the basic string is SSID, and when the wireless connection is Zigbee, the basic string is PANID. It is used as a unique address for each network communication method.

On the other hand, the control unit 204 stores the basic string in the memory unit 203, and receives a connection request message including a basic string generated based on the fingerprint information of the same user through the communication unit, The base string included in the connection request message and the base string stored in the memory unit 203 may be compared to determine whether to form a channel having the base string as a unique address.

In addition, the string generation unit 202 may further generate an extended string in the fingerprint information in addition to the basic string to prevent the basic string from being extracted in the data transfer process of the unique address included in the connection request message. have.

That is, the controller 204 uses the extended string as an encryption seed key according to the communication method of the wireless connection, and includes the basic string in the connection request message and transmits the same through the communication unit. .

Thereafter, the wireless home network system of the other device receives the connection request message encrypted with the extended string, and when the user's fingerprint information is input through the fingerprint reader, generates the extended string together with the basic string. Decoding the connection request message based on the extended string to extract information about the unique address based on the basic string, and from the base string included in the connection request message and the wireless home network system of the other device. It is possible to determine whether to form a channel based on whether the generated basic strings match. When it is determined whether a channel is formed, the wireless home network system of the other device transmits a response message in response to the connection request message, and data transmission is performed by synchronizing signals between wireless home network systems between devices corresponding to the corresponding channel. .

On the other hand, if the communication method of the wireless home network is Bluetooth, the extended string is a PIN (Personal Identification Number) key, and if the wireless connection is a wireless LAN, the extended string is WEP (Wired Equivalent Privacy), TKIP (Temporal Key Integrity) Protocol (CCP) or Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP) key, and when the wireless connection is Zigbee, the extension string may be a PIB (PAN Information Base) key.

Further user authentication may be performed through an encryption and decryption process using an extended string generated from the user's unique fingerprint information, which effectively prevents an intrusion of an external device into the wireless home network.

On the other hand, when it is determined that the channel is formed using the base string as the unique address, the controller synchronizes the signal with the other device that matches the base string through the synchronization unit 206 connected to the communication unit for communication with the other device. can do.

In addition, the controller 204 may be connected to the timer 207 to determine a time for each operation of the wireless home network system. Accordingly, the controller 204 transmits the connection request message for a predetermined time or limits the reception of the response message to the connection request message for a predetermined time based on the time signal set in the timer unit 207. can do.

For example, the controller 204 stores the basic character string in the memory unit 203 in a connection standby state when the response message of the other device is not received for a predetermined time after the transmission of the connection request message for a predetermined time. I can wait. That is, the controller may temporarily store the temporary address set as the default string in the memory unit 203 in the connection standby state and restore the temporary address to the original address so that fingerprint information may be input according to a fingerprint scan of another user. have.

In addition, the controller 204 is configured to scan from the memory unit 203 when the fingerprint scan of the same user is performed on another device and a connection request message from the other device is transmitted. Calls the base string and compares it with the base string included in the connection request message of the other device. If there is a match, the controller 204 transmits a response message to the connection request message to make the base string a temporary address. The connection with the tile can be made.

In addition, when the connection request message including the same basic string as the basic string stored in the memory unit 203 is not received, the memory unit 203 is reset to the initial standby state. Can regress

On the other hand, the control unit 204 can connect to other devices included in the wireless home network using the basic string as a temporary address, and recovers the temporary address to a preset original address after connection with other devices. You can also keep the connection with the tile. By restoring the original address, a user of an additional device not connected to the wireless home network can easily scan his or her fingerprint information on the additional device and a device included in the wireless home network to configure the wireless home network. The additional device may be additionally connected to the wireless home network through the same connection process between the devices.

In this case, the fingerprint scan of the connection of the additional device may be performed only on any one of the existing devices that have constituted the wireless home network with the additional device. This is because data transmission with the additional device can be performed even for the existing device that has not been scanned in the wireless home network by recovering the original address as described above.

3 is a flowchart illustrating a wireless home network configuration method according to the present invention, wherein the wireless home network system scans a user's fingerprint through the fingerprint reader in a standby state (S1) to obtain fingerprint information (S2). Thereafter, a basic string and an extended string are generated based on the fingerprint information (S3), and a connection request message using the basic string as a temporary address according to a communication method is transmitted to the wireless home network system of the other device (S4).

In this case, when the communication method is Bluetooth, the basic string is set as a Bluetooth address, when the communication method is WLAN, the basic string is set as SSID, and when the communication method is Zigbee, the basic string is set as PANID. do.

By transmitting the connection request message for a predetermined time (S5), the fingerprint information through the fingerprint reader is scanned in the wireless home network system of the other device, a basic string is generated based on the fingerprint information, and included in the connection request message. The wireless home network system of the other device transmits a response message based on the match of the basic character string, and the wireless home network system of each device is connected with the temporary string as a temporary address (S13).

In this case, when a response message transmitted from another device is not received (S6), the wireless home network system stores the basic string as a temporary address (S7), and operates in a connection waiting state for a predetermined time (S8).

Thereafter, even if a fingerprint scan is not performed or a response message is not received at the wireless home network system of another device during a preset time (S10), the wireless home network system recovers the temporary address to the original address and operates in a standby state. It may be (S11).

Meanwhile, each device connected to the wireless home network through the above-described process may restore the temporary address used to connect to the wireless home network to the original address (S12).

Subsequently, when an additional device not connected to the wireless home network is to be configured in the wireless home network, a connection request message generated by fingerprint scanning of the additional device is transmitted to a device configuring the wireless home network (S14). ), When the fingerprint scan of the same user as the user of the additional device is performed in the device configuring the wireless home network, the response message of the device included in the wireless home network is transmitted to the additional device and scanned by the additional device. The additional device may easily enter the wireless home network by using the basic string generated based on the fingerprint information of the user as a temporary address.

4 is a flowchart illustrating a wireless home network connection process of the additional device described above, in which a device A and a device B including a wireless home network system scan a user's fingerprint on the first A fingerprint reader to form a wireless home network. (①).

The wireless communication process of the device A is started through the scan, and the personal fingerprint information read from the fingerprint recognition is stored as a unique basic string and an extended string as described above, and the connection request message including the basic string and the extended string is sent. Send to another device (②).

On the other hand, if a connection request is made for a preset time, but there is no connection response of the connection standby device having the information of the same basic string, the connection is not made and the device A is switched to the connection standby state (③).

In this case, when the communication method is Bluetooth in the connection standby state, the device A sets the basic string which is a Bluetooth address as a temporary address and stores the extended string as a PIN key and stays in the connection standby state for a preset time. Similarly, when the communication method is a wireless LAN, the SSID is temporarily stored as a basic string and the WEP key is stored as an extended string and stays for a predetermined time. ZigBee temporarily stores the PANID as a default string and stays for a preset amount of time.

Thereafter, when the fingerprint of the same user is scanned on the device B within a preset time (④), the device B makes a connection request to the device A using the basic string generated from the fingerprint information (⑤). In case of Bluetooth, A device waiting for a connection and B device making a connection request are established with the same basic string as a temporary address, and the Bluetooth pairing process is set using an extension string. , ⑦).

On the other hand, in the case of a wireless LAN, the connection is made by setting the same SSID using the temporary SSID of the basic string and the same WEP key as the extended string for connection between the device B and the device A within a predetermined time.

Similarly, in the case of Zigbee, device B and device A establish a connection using the same basic string PANID within a preset time. In the case of Zigbee, if the security mode is set, the extended string is used as the encryption seed key.

On the other hand, if device A and device B are connected and exchanging data, and device C wants to make an additional connection, fingerprint scan C device (⑧) and send the generated connection request message to device B (⑨). If the device C is connected through a response message to the connection request message or the device C transmits a connection request message for a preset time and there is no response, the device C is fingerprint-scanned at the device B in a connection standby state. The device B may connect with the device C by sending a connection request message to the device C (⑫, ⑭).

In addition, the C device and the A device can be communicated by restoring the temporary address used during the connection between the C device and the B device to the original address, thereby enabling the C device to be connected to the wireless home network consisting of the existing A and B devices.

Operate in connection request state for time.

Subsequently, when a response message to the connection request message is received, a wireless connection is performed to the device that sent the response message as the temporary address and enters a connection state, and the response message is not received for a preset time. In this case, the basic string is stored in the memory and restored to the original address to enter the connection standby state for a preset time.

When the connection request message from the other device is received in the connection waiting state, the previously stored default string is called and compared with the default string included in the connection request message of the other device. Enters the connected state by performing a wireless connection with other devices.

When the connection request message is not received for a preset time in the connection waiting state, the device enters the waiting state and receives a user's fingerprint scan.

In addition, in the connection state, the temporary address may be restored to the original address to receive the user's fingerprint scan, and when the user's fingerprint scan is performed, the user may enter the connection request state and generate and transmit a connection request message.

On the other hand, each operation state of the wireless home network system can be confirmed by the LED display embedded in the fingerprint reader, the status information such as connection status, connection request, connection standby and standby status. For example, if the LED is off, it is in standby, and the LED is rapidly blinking every 1-2 seconds. The LED blinks slowly at 5-10 second intervals and the connection is on. If the LED is on, the connection is on standby. In this way, the wireless home network configuration can be easily configured with a single fingerprint scanning operation.
