The present invention relates to a mobile content service method using a biometric mobile terminal. In particular, the present invention provides a game, utility, entertainment, and security function, which provides a game, utility, entertainment, and security function. It relates to a mobile content service method using a terminal.

In more detail, in applying the biometric technology developed in the past, the mobile terminal provides the functions of games, utilities, and entertainment as well as security by combining the mobile terminal with most of them applied to access control, user security, and time and attendance management. And by making this as a mobile content to enable services on mobile terminals, users can use a variety of services over the Internet while using existing security products, and overcome the limitations of using existing security products The present invention relates to a mobile content service method using a biometric mobile terminal that enables the user to have a more secure life product (eg, a game) by integrating it into a life.

In general, the fingerprint recognition device can accurately check the identity of the user because it uses a fingerprint of the human body that cannot be forged, and can carry other identification means (for example, identification card, magnetic card, password, stamp, etc.). There is an advantage that it is convenient because there is no need, and research on this is being actively conducted in recent years.

A method of performing authentication using a conventional biometric technology will be described with reference to FIGS. 1 and 2 as follows.

First, FIG. 1 illustrates a process of registering user fingerprint data in a conventional biometric device.

As shown here, the user inputs a name in step S11 to register his fingerprint, and if a fingerprint input is requested in step S12, the user contacts the fingerprint with the input portion. In this case, as in step S13, whether the fingerprint is input is checked, and if the fingerprint is not input, the method returns to step S12 to request the fingerprint input. Extract the fingerprint information. In step S15 and step S16, the internal memory storing the fingerprint information is searched to check whether the extracted fingerprint information is stored in the internal memory. As a result of the checking, if the currently extracted fingerprint information is already stored in the internal memory, the process moves to step S17 to display that the currently input fingerprint information is already registered. If the extracted fingerprint information is not stored in the internal memory, the process moves to step S18 to store the currently extracted fingerprint information in the internal memory to register the fingerprint.

2 is a flowchart illustrating a process of performing authentication by a user biometric in a conventional biometric device.

As shown in the drawing, it is checked whether the fingerprint is input in step S21, and if the fingerprint is input as a result of the checking, the fingerprint is imaged in step S22. In step S23, feature points (end points, branch points) existing in the fingerprint are extracted, or ridge information forming a spiral structure inside the fingerprint is extracted. In step S24, the extracted information is generated as a file. In step S25, the generated file information is compared with the fingerprint information already registered in the internal memory, and the similarity is searched. If the mutual fingerprint information is different from the search result, the process moves to step S26 to deny authentication. On the other hand, if the generated file information and the fingerprint information stored in the internal memory are the same, the process moves to step S27 to authenticate the user.

On the other hand, a portable transceiver for performing authentication by applying a fingerprint recognition technology to a conventional mobile communication terminal is disclosed in Republic of Korea Patent Publication No. 2000-0067773 (application date: August 30, 1999: below, "prior art" Abbreviated).

Due to the feature, the biometric mobile terminal 100 has a function of self authentication through a fingerprint as well as a mobile function, and provides users with stronger security than a general mobile terminal. The users having the mobile terminal are connected to the wireless communication network 300, and connect to the Internet network 400 through the wireless communication network 300.

In addition, reference numeral 200 denotes a personal computer (PC), which means a case where a user wants to receive a content service using a web browser from a wired PC. Connect and select the mobile content service you want.

In addition, reference numeral 500 denotes a mobile content providing server for providing mobile contents, and the mobile contents contents are largely composed of sensor applications, utilities, entertainment, security applications, and the like. This mobile content is provided through the Internet network 400.

4 is a block diagram illustrating an embodiment of the biometric mobile terminal 100.

As shown in the figure, a fingerprint sensor 101 for sweeping a user's fingerprint, a data input unit 102 for inputting data such as a function, and information such as a current operation status, execution result, game, etc. are displayed on the screen. A screen display unit 103, an interface unit 104 for interfacing the information of the fingerprint sensor 101, the data input unit 102, and the screen display unit 103 to the control unit 105 at the rear end, and a biometric recognition movement. The controller 105 controls the overall operation of the terminal 100, the memory 106 for storing content information downloaded through the wireless communication network 300, and the mobile content wirelessly connected to the wireless communication network 300. And a transmitter / receiver 108 for downloading mobile content transmitted wirelessly and an RF Bluetooth unit 109 for exchanging data wirelessly with a nearby communication device.

Herein, the configuration and operation of the biometric mobile terminal 100 are similar to those of a conventional mobile terminal, and only the presence or absence of the fingerprint sensor 101 or the RF Bluetooth unit 109 is applied to the technical configuration of the general mobile terminal. Since there is a difference, detailed description of the biometric mobile terminal 100 will be omitted below.

Referring to the operation of the system to which the mobile content service method using the biometric mobile terminal according to the present invention configured as described above is as follows.

The user of the personal computer 200 used in the wired environment and the user of the biometric mobile terminal 100 access the site providing the mobile content service through the wireless communication network 300 and the Internet network 400.

The connected users select their desired mobile content according to each environment, and after authenticating their identity in the biometric mobile terminal 100, they download and use the selected mobile content.

The mobile content using biometrics includes a biometric mobile game, a biometric mobile entertainment, a biometric authentication utility part, a biometric security function, and the like.

In general, mobile devices are limited resources (CPU, memory, etc.), and thus various application systems such as PCs cannot be implemented. Therefore, the basic engine of the biometric system (recognition / authentication / skin measurement / humidity measurement / wrinkle measurement / speed measurement) is embedded inside the terminal through internal embedding, and the user selects a selection item implemented with mobile content. You can download the service that suits you.

5 is a flowchart illustrating a mobile content service method using a biometric mobile terminal according to the present invention.

As shown therein, accessing a website online (S101), accessing a mobile content service site (S102), selecting a mobile content provided by a mobile content providing server (S103), When the selection of the mobile content is made (S104) to check whether the fingerprint sensor is mounted, if the fingerprint sensor is not mounted as a result of the check indicating that the service is not available and returning to the first step (S105), and If the fingerprint sensor is mounted as a result of the checking, the selected mobile content is downloaded and stored in the memory (S106), and the content service is performed using the mobile content stored in the memory (S107).

In the mobile content service method using the biometric mobile terminal according to the present invention as described above, first, the website is accessed online as in step S101.

When the connection with the website is made, the mobile content service site providing a content service that can be used in combination with the fingerprint sensor is connected as in step S102.

When the mobile content service site is connected to the mobile content service site, the mobile content providing server 500 provides the mobile content such as a biometric authentication mobile game, a biometric mobile entertainment, a biometric authentication part, and a biometric security function. In response to the user's manipulation, the biometric mobile terminal 100 selects one of the displayed mobile contents in step S103.

When the selection of the mobile content is completed, it is checked in step S104 whether the fingerprint sensor 101 is mounted.

If the fingerprint sensor is not mounted as a result of the check, the flow proceeds to step S105 to display the service unavailable on the screen display 103, and the process ends.

On the contrary, when the fingerprint sensor is mounted, the mobile station moves to step S106 to download and store the selected mobile content in a memory. In step S107, the corresponding content service is performed using the downloaded content.

6 is a flowchart illustrating a process of performing game content when the selected content is a game.

As shown therein, executing the selected game (S201), sweeping (Sweeping) the fingerprint (S202), imaging the swept fingerprint information (S203), and the imaged fingerprint information Calculating a speed and a position using the step S204; determining a speed Vt and a position Pt based on the calculated value; and performing an operation corresponding to the determined speed and position values. Performing step (S206).

In the game content performing process performed as described above, the game selected by the user is first executed in step S201. Here, the game is a game that can be manipulated using a fingerprint sensor, and such game content is also provided by the mobile content providing server 500.

Next, when the user performs the same operation as the operation key provided on the keypad with the finger in step S202, the fingerprint of the finger is swept by the fingerprint sensor 101. Fingerprint sweeping means scanning sequentially from the top to the bottom of the finger contact.

When fingerprint sweeping is completed, the scanned fingerprint information is imaged (imaged) in step S203.

Then, in step S204, speed information (finger movement speed) and position information (finger position) are calculated. That is, the speed is calculated according to the number of frames of the image, the image is divided into unit blocks, and the position is calculated from the unit block and the center of gravity.

When the speed and position calculation is finished in this way, the speed and position are determined using the calculated value (velocity value / position value) in step S205, and the operation is performed in correspondence with the speed and position in step S206.

For example, when firing a missile in a combat game, the missile launch speed is determined according to the user's finger movement speed, and the finger position becomes the missile launch position.

In other words, when fingerprint information, which is biometric information, is used in a game, the fingerprint information is provided as a new function key, so that the game can be easily and conveniently performed with only a finger.

7 is a flowchart illustrating a wrinkles / humidity measurement process when the selected content is wrinkles / humidity measurement.

As shown therein, when the wrinkle and humidity measurement is selected, the step of sweeping the fingerprint of the user (S301), the step of imaging the swept fingerprint information (S302), and the block of a predetermined size (8 * 8) Dividing the block into blocks or 16 * 16 blocks, wherein the unit is a pixel (S303); calculating a complexity of the divided image (S304); and extracting a feature using a feature index (S305). And analyzing the texture of each unit block (S306), summing all the calculated complexity of each block with respect to an image of one frame (S307), and comparing the sum with a pre-built reference value to determine humidity. And determining the wrinkle level (S308), and displaying the determined result on the screen (S308).

In the wrinkles / humidity measuring method made in this manner, first, when the wrinkles and humidity measurement are selected by the user, the user's fingerprint is swept in step S301.

In step S302, the swept fingerprint information is imaged, and in step S303, the image is divided into blocks of a predetermined size (8 * 8 blocks, or 16 * 16 blocks, wherein a unit is a pixel). Since a method of dividing an image into unit blocks having a predetermined size is already common in image compression techniques such as MPEG-2, 4, and 7, detailed description thereof will be omitted.

Next, in step S304, the complexity of the split image is calculated. The complexity is calculated by the number of images existing in one unit block. That is, assuming that the unit block is 8 * 8, the maximum number of pixels that can exist is 64, which is the highest complexity, and the minimum complexity when the number of pixels is zero.

Next, in step S305, the feature of the block image is extracted using a feature index that is a criterion for classifying features in the fingerprint based on the discontinuities of the fingerprint ridges.

In addition, in step S306, the texture (pattern of the fingerprint image) of each unit block is analyzed.

Subsequently, in step S307, the complexity of each calculated block is added to the image of one frame, and in step S308, the humidity and wrinkles are determined by comparing the sum with a pre-built reference value.

Thereafter, in step S309, the result of the determination is displayed on the screen.
