PCs such as conventional desktops and laptops have security features that allow passwords to be entered when booting the computer or unlocking the screen.

A mobile terminal equipped with a touch screen such as a smart phone or a tablet PC, which has recently become popular, is also set to include such a security function. For example, it is set to release the lock screen by inputting text composed of four or more characters, numbers, or symbols. On the other hand, a method has been devised in which a plurality of grids are provided and a line pattern is received on the basis of a grid to release a lock screen. Such a pattern recognition method is simpler and faster than a password input method, and thus is preferred by many users. Regarding the function of unlocking the pattern recognition, it is disclosed in Japanese Patent Application Laid-Open No. 10-2013-0025325 (published on March 31, 2013).

However, both the text recognition and the pattern recognition are simple, but the method is simple, so that a person around the user can easily grasp and find out by eyes. Accordingly, considering the current situation in which an accident such as hacking or theft of a smart phone is increasing, such conventional lock screen release function does not meet the increasing need for security.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as "comprising ", it means that it can include other elements as well, without departing from the other elements unless specifically stated otherwise.

First, we define the meaning of the terms used below.

The "lock screen" is a screen interface that requires password authentication before using a program or application included in the user terminal. In general, if the lock screen is set in the user terminal, if the power of the user terminal is turned on And is provided on the screen of the user terminal. The " lock screen " also includes a " password interface " that allows a user to enter a password to perform password authentication.

Hereinafter, a user terminal according to an embodiment of the present invention will be described in detail with reference to FIG.

The user terminal 100 according to an exemplary embodiment of the present invention includes a password interface providing unit 110, a password determining unit 120, a lock screen releasing unit 130, a password input analyzing unit 140 and a transparency adjusting unit 150 ). Meanwhile, the configurations 110 to 150 may be implemented by a program module (or application) that provides a password interface.

The password interface provider 110 provides the password interface 200 as shown in FIG. 2 on the lock screen of the user terminal 100 as the lock screen call event occurs. When a lock screen is set in the user terminal 100, a lock screen call event is generated when a message is received from an external terminal or input to a hardware button of the user terminal 100 after the screen power of the user terminal 100 is turned off To turn on the screen power of the user terminal 100. [

The password interface 200 may be composed of a plurality of characters, and each character may be partitioned by a lattice structure. For example, as shown in FIG. 2, characters can be partitioned by a grid structure formed into a single checkerboard shape. On the other hand, the letters may include Korean consonants or English alphabets. First, the case where a character is composed of Korean consonants will be described in detail below. If the letters consist of Hangul consonants, Hangul consonants can consist of a total of 14, from 'A' to 'H' in order of precedence, but this is not necessarily the case. For example, additional twin consonants can be added, making up a total of 19 Korean consonants.

The password interface 200 including a plurality of Korean consonants can be implemented by a total of two interfaces. That is, the password interface 200 may include the integrated password interface shown in FIG. 2 and the separate password interface shown in FIG.

The integrated password interface may be configured such that a lattice structure is formed in one polygon, and Hangul consonants are included in each lattice. In the case of the integrated password interface, when a user who uses a small-sized smart terminal tries to input a password while supporting the smart terminal with one hand, the Korean consonants are tiled together in one area so that an easy input is possible.

The separate password interface may be configured such that a lattice structure is formed in two or more polygons that are separated from each other and a Hangul consonant is included in each lattice. Specifically, the separate password interface includes a left interface 220 and a right interface 210, and the left and right interfaces 210 and 220 are connected to a virtual center line (" CL may be disposed closer to the right edge RL and the left edge LL than the imaginary center line CL, respectively. Each of the left and right interfaces 210 and 220 may include different Hangul consonants, but may include the same number of Hangul consonants. However, the present invention is not limited to this, and the difference in the number of Korean consonants included in the left and right interfaces 210 and 220 may be within a predetermined range. In a further embodiment, the left interface 220 may comprise Hangul consonants and the right interface 210 may comprise Hangul vowels. The separate password interface makes it easier for the user to input passwords. For example, in the case of a large-sized smart terminal, it is difficult for the user to support the smart terminal with one hand. Therefore, the left and right sides of the smart terminal are generally supported by the remaining fingers except for the thumb, The separate password interface is arranged close to the position of the thumbs of both hands, thereby providing a great convenience to the user.

The password determination unit 120 determines whether the password input by the user is a correct password. Specifically, the password determination unit 120 receives a password from the user through the password interface 200, and determines whether the received password matches any one of the passwords stored in advance in the user terminal 100.

The information constituting the password includes the duration of the user's input to each Hangul consonant, the type and input order of the input Hangul consonants, and the order in which the Hangul consonants were input for a long time. For example, a password is set in the order of 'a', 'b', 'c', 'd', but only 'a' or 'b' Can be set to recognize the input. That is, in general, assuming that the time taken by the user to click on the password is 0.2 seconds, the password can be set so that the first Hangul consonant or the second Hangul consonant constituting the password is clicked for a long time. In this case, the number of Korean consonants included in the password interface 200 is 14, but the number of Korean consonants that can be actually input can be increased to 28 by adding long-pressed Korean consonants. The security of the password authentication can be improved. On the other hand, the long-pressed Korean consonants may be set not only for the first or second Korean consonants, but also for the Korean consonants arranged in other order such as the third or fourth consonants.

Also, a plurality of passwords may be stored in the user terminal 100. [ The user can set the password for the lock screen release, the password for the A-application execution, the password for the B-application execution, etc., to be different from each other and store them in the user terminal 100. Here, the password for the lock screen release means a password for releasing only the lock screen, and the password for the application execution means a password including the application execution function in addition to the lock screen release function. When setting a password, the user can set different types of characters as well as different input times for each character, so that many kinds of passwords can be set.

On the other hand, if the user can store and memorize the password for unlock screen release and the password for executing the application in different character combinations, there is no problem. However, if the password for unlocking screen and the password for executing the application are composed of a combination of letters, Can not distinguish between the password for unlocking the screen and the password for executing the application. For example, the user can input a Hangul consonant requesting a user input exceeding a preset time (for example, 0.2 seconds) as a password for the lock screen release in any order (e.g., the second) of the entire password letters , And conversely, it is possible to set the password for executing the application not to include the Korean consonant which requires user input exceeding a preset time (for example, 0.2 seconds). Accordingly, the password determination unit 120 can determine the information of the input password by comparing the information with the password stored in the user terminal 100 in advance.

In addition, the password determination unit 120 may display the input password in a different color than the color of the password interface 200 in advance. Referring to FIG. 4, when the user clicks a Korean consonant of '┌', 'ㅎ', '┌', and 'ㅇ', the shade of the Korean consonants is displayed differently from the color of the password interface 200 . The contrast color may be displayed in the lattice region of the Korean consonant or the Korean consonant input by the user until the completion of the password input from the moment the user inputs the corresponding Korean consonant.

The lock screen releasing unit 130 cancels the lock screen of the user terminal 100 when the input password coincides with any one of the one or more passwords stored in advance.

If the password corresponding to the input password is the password for the lock screen release, the lock screen releasing unit 130 releases only the lock screen. Accordingly, the lock screen releasing unit 130 may display a basic screen (e.g., a home screen) of the user terminal 100 or may display an application that was executed just before the lock screen is set in the user terminal 100 . For example, if the password for the lock screen is set in the order of 'ㅌ', '' ',' '', 'ㅇ', and 'ㅌ' I suppose. 5, if the user inputs' ㅌ ',' ㅎ ',' '', 'ㅇ' in the order of ① ~ ④ and inputs' ㅌ 'for 2 seconds, the lock screen is released, The home screen can be displayed as shown on the right.

Also, if the password matching the input password is the password for executing the application, the lock screen releasing unit 130 releases the lock screen and executes the application stored corresponding to the password. For example, it is assumed that the application execution commands stored in correspondence with these passwords are "he," "a," and "c," respectively. As shown in the left picture of FIG. 6, if a user input is generated in order of a short touch for each Korean consonant, the lock screen is released, and a call application is executed as shown in the right picture, Lt; / RTI > At this time, the passwords 'heh', 'a', and 'c' correspond to the prefix of the name of the person to whom the call is to be sent. 'He,' 'a,' and 'c' may be set in the address book list of the calling application as shown in FIG. That is, the password setting can be set in the execution page of each application. Since the user can easily memorize the password when designating the password after designating the application to be utilized by the user, the user can use very useful and convenient functions through the embodiment of the present invention.

Meanwhile, the example of FIG. 6 relates to an example, and various application execution commands and passwords may be stored correspondingly. For example, after the initialization of the term 'message creation', passwords 'k', 'g', 'y', 'y', and 'g' , 'O', and 'y' after the initialization of the term 'search engine', corresponding to the search window execution command of the portal site application. A list of applications stored in correspondence with the password can be provided as shown in FIG.

The password input analyzing unit 140 analyzes whether the user has succeeded or failed to input a password. Specifically, the password input analyzing unit 140 records the number of password input times of the user when at least one of the plurality of Korean consonants included in the password interface 200 is input to the Korean consonant. If the input password does not coincide with the stored passwords, the password input analyzing unit 140 records the lock screen release failure in association with the password input number. Alternatively, the password input analysis unit 140 may record the number of lock screen cancellation failures.

The transparency adjusting unit 150 may adjust the transparency of the password interface 200 based on the user's password input accuracy. The password input accuracy can be calculated based on the number of password input times recorded by the password input analysis unit 140 and the failure of the lock screen release. Preferably, the transparency adjuster 150 increases the transparency of the password interface 200 as the password input accuracy is higher and decreases the transparency as the password input accuracy is lowered.

Specifically, the transparency adjuster 150 determines whether success or failure of password input has been continuously generated a predetermined number of times (for example, 50 times) by checking the number of password input times in which the lock screen cancellation failure is not recorded. When the success of the password input is consecutively exceeded the preset number of times, the transparency of the password interface 200 can be increased by a predetermined ratio each time the number of password input is generated one more time. For example, the transparency of the password interface 200 may be initially set to 0% as shown in the leftmost diagram of FIG. When successive input of 50 consecutive passwords occurs, the transparency of the password interface 200 starts to increase by 10% from the input of the 51st password. At the time of inputting the 55th password, the translucent password interface 200 may be provided. Then, when the 60th password is input, the transparency of the password interface 200 becomes 100%, and the password interface 200 may not be completely displayed on the lock screen as shown in the rightmost picture of FIG. The user can directly set the password input frequency and the transparency control according to the lock screen release failure as shown in FIG.

In a further embodiment, when the lock screen release failure is recorded after the transparency of the password interface 200 is increased, the transparency adjuster 150 controls the transparency of the password interface 200 in proportion to the number of times the lock screen release failure is recorded Transparency may be lowered. For example, after successive input of 50 consecutive passwords occurs, the transparency of the password interface 200 provided at the 55th time is set to 50%, and the transparency is lowered by 10% Can be set. If the lock screen failure fails five consecutive times, the transparency can be set back to 0%.

Further, as a further embodiment, the transparency adjusting unit 150 may set the transparency of the password interface 200 based on the password input exercise result. An embodiment of the present invention can provide a password practice interface. After setting a password, a password practice interface is provided. A lattice type exercise board composed of a Korean consonant or an English alphabet is provided so that a user can practice a password input Interface. At this time, the password practice interface can also control the transparency of the practice board based on the accuracy of the password input by the user. As the number of occurrences of the password is smaller, the transparency of the practice board can be increased. If transparency is set to 80% as a result of password input through the practice keyboard, the transparency adjuster 150 may set the transparency of the password interface displayed on the lock screen to 80% after the execution of the practice keyboard is completed. Therefore, when the user sets the password and exercises through the practice board to make the error rate 0%, the user can immediately use the transparent password interface.

On the other hand, the object of the transparency adjustment may be the entire password interface 200, but only the Korean consonant portion.

As a further embodiment, a case in which a plurality of characters included in the password interface 200 are composed of a plurality of English alphabets will be described in detail. Referring to FIG. 11, the password interface 200 may be composed of 26 total alphabetic characters. At this time, the pad word interface 200 composed of English alphabets may be configured as a checkered integrated interface as shown in FIG. 11, but it may be configured as a separate interface such that the integrated interface is divided and divided into two as shown in FIG. The detachable interface is characterized in that it is configured to be adjacent to the edge of the user terminal to facilitate the user to enter the password with his right thumb and left thumb, as described above. Furthermore, the integrated interface 200 may be implemented as a Qwerty keyboard as shown in FIG. Since the QWERTY keyboard has the same layout structure as the keyboard layout of the PC, the user can input the password more conveniently than the integrated interface shown in FIG. In addition, the detachable interface may be realized in a form in which the QWERTY keyboard is vertically and separately arranged as shown in FIG. In this case, the size of the key of the QWERTY keypad can be made larger than the one-piece interface of FIG. 13, which is advantageous in that the possibility of typos can be reduced.

Meanwhile, all the functions of the password interface of the Korean consonant, including the above-described unlock function and password interface transparency function, can be applied to the password interface 200 of the English alphabet. For example, the user can set 'H.G.D' as a home screen unlock password after the initialization of HONG GIL DONG. Also, the password for immediately executing the portal site application after unlocking can be set to 'P.T' after the initial consonant of PORTAL. Alternatively, if the portal site application name is NAVER, it can be set to 'N.V' after the English initial consonant, and the password for executing Facebook after unlocking will be 'FB ', Or may be freely set by the user as desired initials.

Further, as a further embodiment, the password interface of the present invention may further include a speech recognition function based on Korean alphabet or English alphabet. That is, the user terminal can set a syllable to which a pronunciation of 'a' or 'a' is added to each word of a password set as a Korean consonant or an English alphabet as a voice password. At this time, the password determination unit 120 of the user terminal may extract the Korean consonant or the English alphabet from the recognized voice and compare it with the original password. Alternatively, when the user terminal recognizes the voice of the user, unlocking may be performed by comparing the recognized voice with the voice password to decide whether to release the lock.

First, if a voice recognition function based on a Korean consonant is described as an example, if a password of a function for requesting a phone call to a terminal of a person named 'Hong Kil-Dong' is already set as 'a.c' If the user terminal recognizes' ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha After unlocking, you can activate the phone call function. Or, when setting the password 'ㅎ a. C', the user terminal can automatically set 'a. A. Da' as a voice password. Accordingly, when the user utters "hahaha", the user terminal compares the recognized voice with 'hahaha' and 'hahaha' and unlocks the phone, .

If a password of a function of requesting a phone call to a terminal of 'Hong Kil-Dong' is already set to 'HGD', the user terminal can set the ' (Ga). Da (Da). ', We identify the initial consonant called' HGD 'from the recognized speech, extract the English alphabet corresponding to the initial consonant, The stored password 'HGD' can be compared and the phone call function can be executed after unlocking. Or 'Ha.Ga.Da.' is automatically set as a voice password corresponding to 'HGD', and when the user utters 'Ga. Da (Da)', Can compare the recognized voice with 'Ha.Ga.Da.', unlock it, and immediately execute the phone call function to the 'Hong Gil Dong' terminal.

In addition, a vowel such as 'ㅗ' or 'o', 'ㅜ', or 'u' may be combined with a Korean consonant or an English alphabet to be a voice password in addition to a vowel a or a.

In such a speech recognition method, since a syllable is composed of a simple word composed of only one vowel and one consonant, a high voice recognition rate can be provided even in a noisy environment. In addition, a simple vowel such as 'a' or 'a' is a unified syllable that can be easily obtained even by people using different languages, so that a certain level of language unification phenomenon may occur between countries. Further, since such a voice password is not a commonly used language, there is an effect of preventing password exposure to a third party as much as possible.

On the other hand, as a further embodiment, one embodiment of the present invention may be applied to a door lock device. For example, when the user terminal 100 is implemented as a door lock device, a password interface as shown in FIG. 15A or 15B is displayed on the outer surface of the user terminal, and when the password input by the user matches a predetermined password, An embodiment of the present invention may be applied in a manner that releases the device lock.

Hereinafter, with reference to FIG. 16 and FIG. 17, a method of releasing a lock screen according to an embodiment of the present invention will be described in detail. The method of releasing the lock screen according to an embodiment of the present invention may be performed by a program module (or application) provided in the password interface 200 installed in the user terminal 100. [

The method shown in FIGS. 16 and 17 includes steps that are processed in a time-series manner in the user terminal 100 shown in FIG. Therefore, even if the content is omitted in the following description, the description of the user terminal 100 described above can also be applied to a method described later. In addition, although the following method has been described based on a password interface composed of Hangul consonants, it can also be applied to a password interface composed of English alphabets.

First, the user terminal 100 provides the password interface 200 according to the occurrence of the lock screen call event (S110). The password interface 200 may comprise a plurality of Korean consonants arranged in a lattice structure.

The user terminal 100 can receive a password from the user through the password interface 200 (S120).

The user terminal 100 determines whether the input password matches one or more previously stored passwords (S130). The password stored in the user terminal 100 may be composed of a plurality of passwords, and may be divided into a password for unlocking the screen and a password for executing the application. In the case of the password for releasing the lock screen, it may be different from the password for executing the application that the user input for the Korean consonants arranged in an arbitrary order is set to exceed a preset time (for example, 1 second). Therefore, the user terminal 100 determines whether or not the password is based on the time duration of the user's input for each Hangul consonant, the type and input order of the entered Hangul consonants, and the order in which Hangul consonants are generated Or not.

The lock screen is released only when the input password matches any one of the passwords (S140).

Then, it is determined whether the password matching the input password is an application execution password (S150). If it is determined that the password is identical to the password, the application corresponding to the application execution password is executed (S160). Thus, the convenience of the user can be increased by reducing the inconvenience that the user releases the lock screen and directly selects and inputs necessary applications.

Next, with reference to FIG. 17, an example of adjusting the transparency of the password interface 200 will be described in detail.

First, the user terminal 100 provides a password interface 200 having transparency of 0% according to the occurrence of a lock screen call event (S210).

When the user terminal 100 receives the password from the user (S220), the user terminal 100 counts the number of password input (S230).

Then, the user terminal 100 determines whether the input password matches one or more passwords stored in the user terminal 100 (S240).

If the passwords do not coincide with each other, it is recorded that the lock screen release is unsuccessful (S250). If the passwords match, it is determined whether succession of password input successively occurs more than a preset number of times (S260). If the lock screen release failure is not recorded while the password input number is recorded a predetermined number of times, successive password input success can be determined.

If the success of the password input has occurred successively more than the predetermined number of consecutive times, the transparency of the password interface 200 is set to be high in proportion to the number of password input successful times exceeding the predetermined number of times (S270). For example, when password success is input 50 times or more, the transparency of the password interface 200 can be set to be higher by 10% each time success of password input is generated one time.
