The present invention relates to a security management method using an iris password of a mobile communication terminal. In particular, the mobile communication terminal itself is registered by the iris password registered in such a state that a user's iris pattern is registered as a security management password by a camera. The present invention relates to a security management method using an iris password of a mobile communication terminal capable of managing security.

The mobile communication terminal, which is a necessity for modern people, is not only compact and lightweight due to steady development, but also is emerging as a complex communication terminal having various functions such as mp3, camera and navigation. In addition to the above functions, the mobile communication terminal has not only its own convenience functions such as a phone book function, a call list display function, an electronic diary (calendar management) function, and a text / voice memo function, but also a short message service function, a wireless Internet service function, and an Internet banking. Various financial transaction functions with external institutions such as an electronic commerce function are provided.

As described above, the mobile communication terminal stores important financial information such as a financial authentication password in addition to various personal information that requires the confidentiality of an individual, so that security management is urgently required.

On the other hand, thanks to the rapid development of the electronic / communication field, biometric identification technology has been widely studied and some of them are commercially available. Some of them are voice recognition, fingerprint recognition, and iris recognition.

Among these biometric methods, the iris recognition method uses a constant immortal iris that is formed before the age of three after human birth. It uses texture information such as iris pattern, shape, and color, and has almost no false recognition rate and false rejection rate. Has characteristics. In other words, the iris, unlike the retina, is located on the surface of the eye, so it is not affected by intraocular diseases, and is not related to eye redness. Image information captured by digital cameras or CCD cameras can be easily processed through image processing. In addition, the number of patterns used for iris recognition is 1078 or more, which may be used as a more complete biometric method than a fingerprint having about 1012 pattern types. In addition, various methods have been researched that can fundamentally prevent iris theft through body harm and a corresponding method by sensing wavelengths occurring in the eyes using light emitting diodes and the like.

Various technologies applying such iris recognition are disclosed. For example, Patent Publication No. 42004 of 2002 discloses a technology for recognizing a user's iris to authenticate a user in credit transactions and electronic commerce. In addition, Korean Patent Publication No. 82895 discloses a system and method for authenticating a user using iris information of a wireless portable terminal user.

However, the password required for security management of the conventional mobile communication terminal has a disadvantage of being easily exposed because it consists of a single digit number string. Accordingly, when the mobile communication terminal is lost or stolen, a huge loss in privacy or financial aspects is lost. There was an issue issuing this. In addition, the password set by the user should always be memorized. Recently, because many passwords are used, it is often confusing what password is used for the mobile communication terminal. There is a problem of seeing a pit.

The present invention has been made to solve the above-described problems, the camera can manage the security of the mobile terminal by the iris password registered in this state in the state that the user's iris pattern is registered in advance as a password for security management. The purpose of the present invention is to provide a security management method based on an iris password of a mobile communication terminal, which enables perfect user authentication and avoids the hassle of memorizing numeric passwords.

In accordance with another aspect of the present invention, there is provided a security management method using an iris password of a mobile communication terminal including a CCD camera and an image processing unit for processing an image input from the CCD camera. Registering an iris image captured by the camera and inputting the iris image by the image processor; (b) setting a lock / unlock state for various functions of the mobile communication terminal using the registered iris password as an authentication means; and (c) obtaining the iris password from the user when the function in the locked state is requested. And determining the use permission according to the result of the comparison with the registered iris password.

Hereinafter, a security management method using an iris password of a mobile communication terminal according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart illustrating an iris password registration process in a security management method using an iris password of a mobile communication terminal of the present invention. As shown in FIG. 2, in step S10, it is determined whether an iris pattern registration key is input through the key input unit 230. When the iris pattern registration key is input, the process proceeds to step S12 to input iris image data. In order to determine whether or not, for example, the user may be informed in advance to input his / her iris image through the CCD camera 282 by text or voice.

As a result of the determination in step S12, when the input of the iris image data is completed, the process proceeds to step S14 to notify the user that the collection of the iris image data has ended so that the user can stop the shooting operation by the CCD camera 282. . Next, in step S16, the iris image input by using the enlargement, reduction, contrast, hue, and saturation of the collected iris image in order to improve the quality of the iris image of the user captured and collected by the CCD camera 282. Image processing is performed on the data.

When the quality of the iris image is improved through the image processing, the feature points of the iris, that is, the iris patterns, are extracted from the iris image of the user who has been image-processed, for example, after determining the pupil and the iris boundary. The left and right radii of the iris are again determined, and the iris image is separated using this information. When the boundary information of the iris is set in this way, the polar coordinates are applied to extract features of the iris. Next, in step S20, a code for each of the extracted iris patterns is generated. For example, the code of the iris pattern generates an IRIS code, and in steps S22 and S24, the code is compressed to reduce the amount of data to be processed and stored. By storing in the data storage unit 244, pattern registration for the iris password is terminated.

3 is a flowchart illustrating a lock / unlock process of a desired function in a security management method using an iris password of a mobile communication terminal of the present invention. As shown in FIG. 3, in step S30, it is determined whether a lock / release setting key for various functions included in the mobile communication terminal is input through the key input unit 230. As a result of the determination in step S30, if the input key is not the lock / unlock setting key, the process proceeds to step S50 to perform another function selected; in the case of the lock / unlock setting key, the process proceeds to step S32 to provide the user with an iris image. Data input is requested, and again in step S34 it is determined whether the input of the iris image data has been completed, and the user photographs and inputs his iris by the CCD camera 282 according to the request in step S32. Of course, in this process, as in step S12 of FIG. 2, the user may be notified that the collection of the iris image data is completed.

As a result of the determination in step S34, when the input of the iris image data is completed, in step S36 the image processing processing, iris pattern extraction, iris pattern coding and data are inputted in the same manner as in steps S16 to S22 of FIG. Compressed data is obtained through compression. Next, in steps S38 and S40, it is determined whether the iris pattern data thus obtained matches the iris password previously registered in the data storage unit 244 in step S24 of FIG. As a result of the determination in step S40, if there is a match, the flow advances to step S42 to display a list of lockable functions on the flat panel display 262, whereas if there is a mismatch, the flow goes to step S48 to use the lock / unlock function. You will be notified.

FIG. 4 is an exemplary view of a display screen for setting a lock / release in FIG. 3. As shown in Fig. 4, the lockable function list includes a voice call call function, a wireless Internet access function, a call list check function, an international call call function, a phonebook check function, a text message check function, and an electronic diary use and check function. And the like, in addition to the text (voice) memo check function and may be further included, such as setting of the time available by the one-time authentication to be described later. In addition, the user can easily and collectively set or release locks on a desired function list by operating a key button corresponding to a check box provided to the left of the displayed function list. The "V" mark on the check box of the example screen of FIG. 4 indicates the lock state, and the absence of such mark indicates the unlock state. The "V" mark appears by the toggle operation of the designated button. You can set the program to disappear. According to this, a list of more functions is displayed on a screen of a smaller size than the method of displaying the lock state and the unlock state in two lines for the same function, and displaying them by inverting colors when the lock state or the unlock state is selected. You can show them all at once.

3, in step S44, it is determined whether the check for the lock has been completed, and if so, the lock / release setting process is terminated by storing the checked content in the data storage unit 244.

5 is a flowchart illustrating a security management process in a security management method using an iris password of a mobile communication terminal of the present invention. As shown in Figure 5, according to the security management process of the present invention, in step S60 it is determined from the user whether any function provided in the mobile communication terminal is required. As a result of the determination in step S60, if any function is requested, the process proceeds to step S61 to determine whether the function is currently locked. If not, the process proceeds to step S76 to immediately accept the request, that is, the function. Will be used. On the other hand, in the case of the locked state, the process proceeds to step S62 to determine whether a predetermined time has elapsed since the use of the license. This step S62 is given to enable more thorough security, and the predetermined time at this time is randomly selected by the user. It is desirable to be able to change.

As a result of the determination in step S62, if the predetermined time has not passed after the use permission, the flow proceeds to step S76 to permit use. On the other hand, if the predetermined time has elapsed as a result of the determination in step S62, the flow advances to step S64 to request the user to input the iris image data for authentication again, and again in step S66 whether the input of the iris image data is completed. In determining the iris, the user captures and inputs his iris by the CCD camera 282 according to the request in step S64. Of course, in this process, as in step S12 of FIG. 2, the user may be notified that the collection of the iris image data is completed.

As a result of the determination in step S66, when the input of the iris image data is completed, in step S68, the input iris image data is processed in the same manner as in steps S16 to S22 of FIG. Compressed data is obtained through compression. Next, in steps S70 and S72, it is determined whether the iris pattern data thus obtained matches the iris password previously registered in the data storage unit 244 in step S24 of FIG. As a result of the determination in step S72, if there is a mismatch, the flow proceeds to step S74 to disable the use, and if it matches, the flow proceeds to step S74 to permit use.
