Patent number 8554177 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates to a mobile device, and, more particularly, to an apparatus for and a method of unlocking a touch-input mobile device by embodying an unlocking function using pattern recognition, thereby increasing user convenience and ensuring security improvement.
"Mobile devices such as mobile phones are used daily by many people, and a wide variety of private information is stored in them.
"In particular, since private information, including phone numbers, data related to credit card payment, data related to stock transaction, requires a greater degree of security is stored in the mobile device, it has become an important issue to restrict a third party from accessing the private information using a locking function of a mobile device.
"FIG. 1 is a flowchart illustrating a method of unlocking a conventional mobile device.
"As shown in FIG. 1, in a conventional mobile device having a locking function set thereto (S101), when a numeric password is input through a keypad (S102), it is checked whether the input numeric password is identical with a numeric password preset by a user (S103). If the input numeric password is identical with the preset numeric password, the locking function set in the mobile device is canceled to allow the user to use the device (S104).
"However, prior to use of the mobile device, due to the inconvenience having to enter passwords, users tend to be reluctant to use a locking function of the mobile device.
"In recent years, there has been a gradually increasing demand for a large display in mobile devices. Further, a considerable amount of power consumed in such a mobile device is attributable to power consumption by the LCD unit. Accordingly, it is desirable to block power applied to the LCD unit when the mobile device is not used.
"A power supply control switch or a touch sensor has conventionally been used to control power applied to an LCD unit of a mobile device.
"However, in a mobile device that is usually put in a pocket or bag while it is not in use, the power applied to the LCD unit is controlled by means of a separate control switch or by a keypad for simple touch input, the control switch or keypad is likely to be inadvertently pressed, resulting in unnecessary power consumption."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "The present invention provides an apparatus for unlocking a mobile device using pattern recognition, which can increase user convenience and ensure security improvement by embodying an unlocking function using pattern recognition in a mobile device based on a touch input mechanism.
"The present invention also provides an apparatus for unlocking a mobile device using pattern recognition, which can prevent unnecessary power consumption by interrupting power supplied to an LCD when the mobile device is not used.
"The present invention also provides a mobile device having the unlocking apparatus.
"The present invention also provides a method of unlocking a mobile device using pattern recognition according to an embodiment of the present invention.
"The above and other objects of the present invention will be described in or be apparent from the following description of the preferred embodiments.
"According to an aspect of the present invention, there is provided an apparatus for unlocking a mobile device using pattern recognition, the apparatus including a touch sensor unit sensing a predetermined pattern touch-input to a liquid crystal display (LCD) unit, a pattern recognition unit recognizing information about the input pattern sensed by the touch sensor unit, a pattern comparison unit comparing information about the input pattern recognized by the pattern recognition unit with information about a predetermined pattern set by a user, and a controller controlling power supply to the LCD unit to enable the user to use the mobile device if the input pattern and the predetermined pattern are equal to each other as compared by the pattern comparison unit.
"According to another aspect of the present invention, there is provided a method of unlocking a mobile device using pattern recognition, the method including sensing a predetermined pattern touch-input to a liquid crystal display (LCD) unit, recognizing information about the input pattern, comparing the recognized information about the input pattern with information about a predetermined pattern set by a user to determine whether the input pattern and the predetermined pattern are equal to each other, and, if the input pattern and the predetermined pattern are equal to each other, applying power to the LCD unit to enable the user to use the mobile device."
