The present invention relates to a sensing technology such as fingerprint recognition, and more particularly, to a wireless sensing device and method for enabling user information sensing and authentication according to various digital devices.

In general, the most popular technologies for security detection are security card recognition and fingerprint recognition technology. While security card recognition is relatively easy to steal other people, fingerprint recognition is receiving higher expectations and attention in terms of security and safety because authentication is performed through fingerprints, which are unique features of the human body.

1 is a diagram illustrating a conventional fingerprint recognition process. Referring to this, when a user recognizes a fingerprint in each device, the device reads the fingerprint, converts the value into a database, and compares the stored data with an authentication procedure. Enable the use of the device.

In a conventional fingerprint recognition module, a fingerprint recognition sensor is included as a component in a device such as a computer, an IC card, and a mobile phone. As such, the fingerprint sensor is limited to its use in being composed of one of all the components of the device.

For example, a sensor in a notebook can only be used in a notebook, while a sensor included in a cell phone can only be used in a cell phone. Therefore, only the product equipped with the fingerprint sensor could be used for security authentication using the fingerprint sensor.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a wireless sensing device and method for enabling user information detection and authentication according to various digital devices.

Another object of the present invention is to provide a wireless sensing device and method for transmitting authentication information to a digital device that is not provided with a sensing sensor to perform authentication.

The wireless sensing device and method according to the present invention make it easy for people to carry by making a fingerprint sensor and a wireless communication module into one. In addition, by using only one wireless module with a fingerprint sensor, it is possible to use a fingerprint recognition method for all devices using various Bluetooth communication methods. You can use this module to authenticate and connect to any device, as you would carry a security card for Internet banking, and multiple users can use it. It is very helpful to activate fingerprint recognition security because it is possible only if your fingerprint data is in the device or application you want to access.

In addition, the present invention can remove the existing line by making a portion of the existing wire to the wireless. In addition, it is advantageous to commercialize the product by using Bluetooth technology, which is widely used in computers, personal mobile devices, and PMPs, and it is advantageous for personal information security by strengthening the security of various devices by allowing the user to carry the wireless sensing device at all times. . In other words, by removing the inconvenience and limitations of the existing line and sending fingerprint recognition data wirelessly, the ripple effect on the spread of sensors and Bluetooth is great.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

The interface module 220 converts the biometric information to be suitable for the interface of the wireless communication module 230. For example, the fingerprint data in the form of raw data may be converted to be recognized by the Bluetooth module.

The wireless communication module 230 may be a short range wireless communication module including a Bluetooth module, an IrDA module, a ZigBee module, and the like. The Bluetooth module is preferable in terms of unit cost, utilization, and efficiency.

As shown in FIG. 3, the wireless sensing apparatus 300 according to another embodiment of the present invention includes a fingerprint recognition sensor 310 for receiving fingerprint data from a user; A data acquisition driver 320 for converting fingerprint data input to the fingerprint recognition sensor 310 into a Bluetooth interface; A Bluetooth baseband unit 330 for converting data input from the data recognition driver 320 into a baseband analog signal; A Bluetooth transceiver 340 for converting the baseband signal output from the Bluetooth baseband unit 330 into a frequency (for example, 2.4GHz) to be outputted; It may be configured to include a wireless module 350 for wirelessly transmitting the signal output from the Bluetooth transceiver 340.

3 and 2, the fingerprint recognition sensor 310 of FIG. 3 corresponds to the biometric sensor 210 of FIG. 2, and the data recognition driver 320 of FIG. 3 is connected to the interface module 220 of FIG. 2. The Bluetooth baseband unit 330, the Bluetooth transceiver 340, and the wireless module 350 of FIG. 3 correspond to the wireless communication module 230 of FIG. 2.

Looking at the operation configuration of the wireless sensing device 300, first, the fingerprint recognition sensor 310 detects the user's fingerprint to generate and output the fingerprint data in the form of raw (RAW) data. The data recognition driver 320 converts the fingerprint data so that the Bluetooth modules 330 and 340 can recognize the fingerprint data.

Fingerprint sensors currently in use typically have either a Serial to Parallel Interface (SPI) or a parallel interface. In the case of Bluetooth, UART (Universal Asynchronous Receiver / Transceiver) interface is used for data input. The data recognition driver 320 performs a function of matching each interface. In addition, since the data entered after the fingerprint recognition is raw data, the component may be configured to receive data in the form of data required for communication with Bluetooth.

Bluetooth data properly converted for Bluetooth communication is input to a Bluetooth digital terminal, that is, the Bluetooth baseband unit 330. Data input to the UART interface may be configured in a form suitable for Bluetooth communication. Data passing through the Bluetooth baseband unit 330 is converted into an analog signal and the converted data is converted to a frequency to be used by the Bluetooth transceiver 340. And the RF component for Bluetooth data communication, that is, the wireless module 350 to send data made in 2.4GHz to communicate.

The wireless module 350 may include a transmission / reception switch 352, a balloon 354, a band pass filter (BPF) 356, an antenna 358, and the like.

Fingerprint sensor and wireless communication module can be manufactured as one module. In the present invention, only the case where the fingerprint sensor and the Bluetooth module are connected is described. However, in some cases, the fingerprint module may be wirelessly implemented using another wireless product instead of the Bluetooth.

In general, when connecting the fingerprint sensor and the wireless communication component, the interface module that is interconnected may be configured in other forms. If the fingerprint sensor uses only the parallel interface and the Bluetooth module uses only the SPI, a module for the interface can be manufactured. In some cases, when a large amount of fingerprint recognition data is needed, a module for an interface may be configured by inserting a small memory or CPU corresponding to the buffer.

When building a product that requires personal authentication, you can use a sensor other than a fingerprint sensor and implement the technology wirelessly.
