Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the control unit 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different wireless interfaces and / or physical layers. For example, wireless interfaces that can be used by a communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA) ), Universal mobile telecommunication systems (UMTS) (in particular Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications May be included.

Hereinafter, for the sake of convenience of description, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to all communication systems including an OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system as well as a CDMA wireless communication system.

A CDMA wireless communication system includes at least one terminal 100, at least one base station (BS) (also referred to as a Node B or Evolved Node B), at least one Base Station Controllers (BSCs) , And a Mobile Switching Center (MSC). The MSC is configured to be coupled to a Public Switched Telephone Network (PSTN) and BSCs. The BSCs may be paired with the BS via a backhaul line.

A broadcast transmission unit (BT) transmits a broadcast signal to terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1 is provided in the terminal 100 to receive a broadcast signal transmitted by the BT.

In addition, a Global Positioning System (GPS) may be associated with the CDMA wireless communication system to identify the location of the mobile terminal 100. The satellite aids in locating the mobile terminal 100. Useful location information may be obtained by two or more satellites. Here, the position of the mobile terminal 100 can be tracked using all the techniques capable of tracking the location as well as the GPS tracking technology. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmissions.

The location information module 115 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal, and may include a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 115 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a WPS (WiFi Positioning System) can be utilized to compensate the positioning of the GPS system.

The WiFi Positioning System (WPS) is a system in which a mobile terminal 100 uses a WiFi module included in the mobile terminal 100 and a wireless AP (wireless access point) transmitting or receiving a wireless signal with the WiFi module, Is a technology for tracking a location of a wireless local area network (WLAN) using WiFi.

The WiFi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which certain wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP can transmit the location information request message to the Wi-Fi location server.

The Wi-Fi position location server extracts information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi position location server through the mobile terminal 100, or may be transmitted from the wireless AP to the Wi-Fi location server.

The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Then, the Wi-Fi location server can extract (or analyze) the location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.

As a method for extracting (or analyzing) the position information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

The landmark method is a method of measuring the position of a mobile terminal using a landmark transmitter that knows the location.

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

The location information of the extracted mobile terminal 100 is transmitted to the mobile terminal 100 via the Wi-Fi location server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may be connected to at least one wireless AP to obtain location information. At this time, the number of wireless APs required to acquire the location information of the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

Alternatively, the control unit 180 may control the display of the login screen for the web site, and display the web site with the ID and password stored in the memory 170 being input into the login and password input window .

Next, a password management method according to another embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 5, the ID and password display screen 800 shown in FIG. 8 is a screen to be displayed when an input for selecting one item from a user is received. The web site name 810 and an icon 820 ), An ID 830, a password 840, and a website address 860 as well as a password hint 850.

The display unit 151 further displays a password hint 850 to the user instead of encrypting the password and displaying the encrypted password 840 in order to prevent peeping.

To this end, the control unit 180 may receive the password hint 850 along with the website name 810, the ID 830 and the password 840, and store the password hint 850 in the memory 170.

The user can memorize the password while preventing the password from being exposed through the password hint 850 stored in advance together with the password.

Next, a password management method according to another embodiment of the present invention will be described with reference to FIGs. 9 to 10. FIG.

9 is a view for explaining an operation of the mobile terminal 100 to detect the device 900 displaying the web.

As shown in FIG. 9, there may be a device 900 that displays a login screen 910 for a web site in the vicinity of the mobile terminal 100.

The control unit 180 first senses the surrounding device 900 and can detect the web site login screen 910 displayed by the detected device.

The control unit 180 can acquire the website name corresponding to the detected web site login screen 910.

The control unit 180 can acquire the ID and password corresponding to the acquired website name in the memory 170. [

10, the control unit 180 displays a website name 1010 and an icon 1020, an ID 1030 and a password 1040 corresponding to the website name 1010 acquired in the peripheral device 900 displaying the website ) To the peripheral device 900. The peripheral device 900 may be connected to the peripheral device 900 via a network.

At this time, the control unit 180 can transmit to the peripheral device 900 a command for encrypting and displaying the password in the peripheral device 900 displaying the website.

The peripheral device 900 may receive a command to display the website name 1010 and the corresponding icon 1020, the ID 1030 and the encrypted password 1040 on the display unit.

As the peripheral device 900 receives the command, it may display the website name 1010 and the corresponding icon 1020, the ID 1030, and the encrypted password 1040.

The location where the website name 1010, the icon 1020, the ID 1030, and the encrypted password 1040 are displayed is only an example.

Further, the website name 1010 or the icon 1020 may be omitted.

Alternatively, according to another embodiment of the present invention, the control unit 180 automatically inputs an ID and a password stored in the memory 170 in the ID and password input window on the website login screen displayed by the peripheral device 900 To the peripheral device (900). In this case, not only the password is not exposed, but also it is possible to reduce the trouble for the user to input the ID and the password.

In this manner, when the peripheral device 900 is sensed and a signal for displaying an ID and a password is transmitted, since it is not necessary to store the ID and password information in the peripheral device 900, the memory can be saved and security can be further enhanced .

9 to 10, a wearable device such as a SmartWatch is exemplified as the peripheral device 900 displaying the web, but any device capable of wirelessly interfacing with a smartphone or a tablet may be included. For example, the mobile terminal 100 can sense a web site displayed by smart glasses or a band-type device, and transmit a signal.

In this case, the mobile terminal 100 must include a password management function. However, the mobile terminal 100 only needs to include a password management function, but does not mean that it requires execution of a password management function. The display of the password management list 400 by the mobile terminal 100 of FIG. 9 is intended to illustrate that it includes a password management function, and does not necessarily have to display the password management list 400.

Fig. 2 will be described again.

The user input unit 123 receives an input for touching a part of the encrypted password (S103).

The mobile terminal 100 can receive an input that touches a part of the encrypted password displayed on the display unit 151. [

The touch input can be received by decompression, optical, electrostatic capacity, ultrasonic or pressure method.

The display unit 151 displays the unencrypted password corresponding to the touched portion of the encrypted password (S105).

The control unit 180 displays the unencrypted password on the display unit 151 only for the portion corresponding to the touched portion, so that the entire password can be prevented from being exposed.

This is because it is easy for a user to guess only a part of a password, but it is difficult for others to guess the entire part of the password.

The unencrypted password refers to the password stored in the memory 170. For example, when the password 'black00000' is stored in the memory 170, the encrypted password means '**********' and the unencrypted password can mean 'black00000' have.

11 to 18, a screen in which the display unit 151 of the mobile terminal 100 displays a part of the password will be described.

The number of characters in the displayed unencrypted password is set to the default value, or can be set by receiving input from the user.

The number of characters to be displayed may be set to one, two, or three, but this is merely an example.

11 is a view for explaining an operation of displaying a non-encrypted password corresponding to a portion where a touch input is received in a password list screen 300 according to an embodiment of the present invention.

11, the user input unit 123 may receive an input that touches a portion 1110 of the encrypted password, and the control unit 180 determines whether the unencrypted password corresponding to the touched portion, "ck Quot; 1120 " 11 shows a case where the number of characters to be displayed is set to two.

12 is a view for explaining an operation of displaying an unencrypted password corresponding to a portion receiving the touch input in the ID and password display screen 700 according to another embodiment of the present invention.

12, when the user input unit 123 receives an input touching a portion 1210 of the encrypted password 740, the control unit 180 determines whether the unused password is an unencrypted password corresponding to the touched portion quot; ck "(1220). 12 shows a case where the number of characters to be displayed is set to two.

Next, Fig. 13 is a diagram for explaining a screen for displaying an unencrypted password when the number of characters displayed by the display unit 151 is set to 1. Fig.

As the user input unit 123 receives an input touching a portion 1310 of the encrypted password 740, the control unit 180 displays the unencrypted password "a" 1320 corresponding to the touched portion Can be displayed on the display section (151).

13 shows the case where the password stored in the memory 170 is "black00000 ", and the display portion 151 sequentially displays" c "," k " Can be displayed.

Next, Fig. 14 is a view for explaining a screen in which a circle symbol representing the touched portion 1410 is omitted, unlike Figs. 11 to 13, on the screen for displaying the unencrypted password corresponding to the touched portion 1410 to be.

As such, the circle symbol representing the touched portion 1410 is an example, and the display portion 151 may include or omit a circle symbol.

15 is a view for explaining an operation of displaying an unencrypted password corresponding to a portion where the touch input is received in the ID and password display screen 800 according to another embodiment of the present invention.

A password hint 850 can be further displayed on the ID and password display screen 800 of Fig. 15 and the user can refer to a part 1520 of the password displayed through the touch input together with the password hint 850, It is easier to guess.

For example, the user can guess without having to input 'black' through the 'my favorite color' hint previously set by the user, so that the password can be stored by touch inputting the remaining part.

Next, an operation of displaying the brightness and the brightness of the password differently according to the strength of the touch input will be described.

Fig. 16 is a diagram for explaining an example in which the brightness of the password is varied depending on the strength of the touch input.

The control unit 180 can acquire the intensity of the touch input.

For example, when the touch input is not detected, the controller 180 can see the intensity as 0 and the intensity when the touch input is detected as the maximum.

Therefore, when the intensity of the touch input sensed by the controller 180 is 0, the password is not displayed, and when the intensity of the touch input is 10, the password can be displayed in the darkest black. Similarly, as the intensity of the touch input increases from 1 to 9, the display unit 151 can darkly display the contrast of the displayed password.

FIG. 16 is a diagram illustrating a case in which the strength of the touch input is weak and the strength of the touch input is strong, and the contrast of the password is displayed differently.

16, the intensity of the touch input is lower than the intensity of the touch input in the right screen of FIG. 16, and the password of the left screen is displayed more blurred than the password of the right screen.

When the intensity of the touch input is weakly sensed, the display unit 151 displays the password in a blurred manner, thereby preventing the peeping more effectively.

The user may touch the portion of the password that he or she wants to check with a weak touch so that only the user can view it, so as to prevent the password from being partially exposed.

17, a screen for displaying a password on the device 900 that has received the password information from the mobile terminal 100 including the password management function will be described.

Upon receiving the password information, the device 900 displays a part of the password encrypted by the user on the screen 910 displaying the received website name 1010, icon 1020, ID 1030 and encrypted password 1040 Quot; bl "1820, which is an unencrypted password corresponding to the touched portion, upon receiving an input touching the touch screen 1810. [ "A" and "ac" can be displayed in turn as the part receiving the touch input moves to the right.

Next, an operation of outputting a password by voice will be described with reference to Fig.

18 is a password display screen 1900 including an icon 1910 for outputting a password as a voice.

Upon receipt of an input touching the voice output icon 1910, the control unit 180 can output the password stored in the memory 170 by voice. In this case, the control unit 180 controls the size of the outputted voice to be small enough to be heard only by listening to the speaker of the mobile terminal 100. [

Thus, the user can confirm the password by the speaker without going through the display unit 151. [

It is a matter of course that a non-encrypted password can be confirmed by touching a part of the encrypted password 1920 in this screen.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet).
