     DETAILED DESCRIPTION 
       [0035]    To present the objects, solutions, and advantages of the embodiments of the present disclosure in a clearer manner, detailed descriptions of the embodiments of the present disclosure will be further given below in conjunction with the figures. Here, the illustrative embodiments of the present disclosure and the description thereof are given for the purpose of illustration only, not for the purpose of limitation. 
         [0036]      FIG. 1  is a schematic diagram of an interface of a security device in accordance with an embodiment of the present disclosure. The security device  100  comprises a photographing module (not shown) such as a camera and a display module  120  such as a display screen. The security device  100  may be any device comprising, but not limited to, a mobile phone, a tablet computer, a desktop computer, or a notebook computer, or the like. There are several icons, such as,  130 ,  140 ,  150 , and  160 , on the display module  120 . The objects represented by these icons comprise, but not limited to, an image, a video, an app, or an interface, etc. 
         [0037]    Taking the icon  130  as an example, the object it represents is an app. When a user clicks this icon  130  via a mouse, a keyboard, a touch screen, etc., a process of a method in accordance with an embodiment of the present disclosure is shown in  FIG. 4 . 
         [0038]    At Step S 10 , an image, which is being captured by the photographing module, is displayed on the display module  120 , while the photographing module is in the photo taking mode or video taking mode. 
         [0039]    At Step S 20 , when the photographing module captures a specific image, a password input interface is displayed on the display module  120 . This specific image may contain any of color, luminance, or pattern, which meets a predetermined condition, or any combination thereof. 
         [0040]    Embodiments utilizing color, luminance, and pattern are described as follows, respectively. 
         [0041]    1. Embodiment Utilizing Color 
         [0042]    The user sets a certain color value as the base color in advance, and sets positive/negative tolerances. In this way, a color represented by a color value within the range of the positive/negative tolerances is a trigger color. When the photographing module captures an image, it divides the image into n×n pixel units (the number of pixels may be equal to or less than the resolution of the photographing module, and in the case where the number of pixels is less than the resolution of the photographing module, the color value of each unit is equal to the average of the color values of all actual pixels within this unit). If a ratio of the number of the pixel units which have color values within the tolerance range to the total number of the pixel units exceeds a set value (for example, 80%, but not limited thereto, which may be set based on the actual needs), it may be determined that the trigger color is met. In other words, the specific image is captured. 
         [0043]    2. Embodiment Utilizing Luminance 
         [0044]    The user sets a certain luminance value as the base luminance in advance, and sets positive/negative tolerances. In this way, a luminance represented by a luminance value within the range of the positive/negative tolerances is a specific luminance. When the photographing module captures an image, it divides the image into n×n pixel units (the number of pixels may be equal to or less than the resolution of the photographing module, and in the case where the number of pixels is less than the resolution of the photographing module, the luminance value of each unit is equal to the average of the luminance values of all actual pixels within this unit). If a ratio of the number of the pixel units which have luminance values within the tolerance range to the total number of the pixel units exceeds a set value (for example, 80%, but not limited thereto, which may be set based on the actual needs), it may be determined that the trigger luminance is met. In other words, the specific image is captured. 
         [0045]    3. Embodiment Utilizing Pattern 
         [0046]    The user draws a contour on the display module  120  as the trigger pattern, and the contour may not be closed. When the photographing module captures an image, it will detect an object in the image (when necessary, the detection may be performed at different focal lengths, and the detection may determine edge lines of the object based on a color contrast value, but not limited thereto), so as to compare the detected edge lines of the object with the trigger pattern. If matched, the trigger pattern is met. In other words, the specific image is captured. 
         [0047]    Of course, the above three embodiments are given for the purpose of illustration only. Any method that can distinguish color, luminance, or pattern of an image may be used. 
         [0048]    Furthermore, the set password may be text or pattern, and therefore the password input interfaces are shown as  FIG. 2  and  FIG. 3 , in which  FIG. 2  is a text input interface and  FIG. 3  is a pattern input interface. In  FIG. 3 , a pattern may be formed by connecting dots. Of course, the password input interface may also be a combination of the both. It should be appreciated that the above password setting and input methods are merely examples, and any appropriate method for password setting and inputting may be used. 
         [0049]    At Step S 30 , it is judged whether a password is matched. 
         [0050]    At Step S 40 , if the password is matched, then an object expected by the user (i.e., an app) is displayed on the display module  120 . 
         [0051]    At Step S 50 , if the password is not matched, when a predetermined number of failures is reached, the display module  120  prompts the user that no input is possible. The current information is recorded and transmitted to a predetermined address in a predetermined way. The current information comprises, but not limited to, time, location (for example, acquired via a GPS device), background (for example, acquired via the photographing module), etc. For example, the time is Apr. 16, 2012, Monday, and the location is 39° 54′ north latitude and 116° 23′ east longitude. The predetermined way comprises, but not limited to, any of a phone call, a voice message, an SMS message, an MMS message, an email, an instant messenger, and a social network, or any combination thereof. The predetermined address may be preset by the user or chosen from a location such as an address book. Of course, a warning may be issued in any other existing way. 
         [0052]    In this embodiment, within the predetermined number of failures (for example, 10 times), the user may keep trying until the predetermined number of failures is reached. The user may record the number of failures. 
         [0053]    The present disclosure further provides a security device  200 . As shown in  FIG. 5 , it comprises a photographing module  201 , a display module  202 , a determining module  210 , a judging module  220 , a recording module  230 , and a transmission module  240 . 
         [0054]    The photographing module  201  is a module that is capable of capturing an image, and it comprises but not limited to a camera. The photographing module  201  is configured to capture an image in a photo taking mode or a video taking mode. 
         [0055]    The display module  202  is a module that is capable of displaying an icon, an image, an app, an interface, or the like. It comprises, but not limited to, a display screen or a touch screen, or the like. 
         [0056]    The determining module  210  is configured to have the display module  202  present a password input interface when it is determined that a specific image is captured by the photographing module  201 . This specific image comprises any of color, luminance, or pattern, which meets a predetermined condition, or any combination thereof. 
         [0057]    Embodiments utilizing color, luminance, and pattern are described as follows, respectively: 
         [0058]    1. Embodiment Utilizing Color 
         [0059]    The user sets a certain color value as the base color in advance, and sets positive/negative tolerances. In this way, a color represented by a color value within the range of the positive/negative tolerances is a trigger color. When the photographing module  201  captures an image, it divides the image into n×n pixel units (the number of pixels may be equal to or less than the resolution of the photographing module  201 , and in the case where the number of pixels is less than the resolution of the photographing module  201 , the color value of each unit is equal to the average of the color values of all actual pixels within this unit). If a ratio of the number of the pixel units which have color values within the tolerance range to the total number of the pixel units exceeds a set value (for example, 80%, but not limited thereto, which may be set based on the actual needs), it may be determined that the trigger color is met. In other words, the specific image is captured. 
         [0060]    2. Embodiment Utilizing Luminance 
         [0061]    The user sets a certain luminance value as the base luminance in advance, and sets positive/negative tolerances. In this way, a luminance represented by a luminance value within the range of the positive/negative tolerances is a specific luminance. When the photographing module  201  captures an image, it divides the image into n x n pixel units (the number of pixels may be equal to or less than the resolution of the photographing module  201 , and in the case where the number of pixels is less than the resolution of the photographing module  201 , the luminance value of each unit is equal to the average of the luminance values of all actual pixels within this unit). If a ratio of the number of the pixel units which have luminance values within the tolerance range to the total number of the pixel units exceeds a set value (for example, 80%, but not limited thereto, which may be set based on the actual needs), it may be determined that the trigger luminance is met. In other words, the specific image is captured. 
         [0062]    3. Embodiment Utilizing Pattern 
         [0063]    The user draws a contour on the display module  202  as the trigger pattern, and the contour may not be closed. When the photographing module  201  captures an image, it will detect an object in the image (when necessary, the detection may be performed at different focal lengths, and the detection may determine edge lines of the object based on a color contrast value, but not limited thereto), so as to compare the detected edge lines of the object with the trigger pattern. If matched, then the trigger pattern is met. In other words, the specific image is captured. 
         [0064]    Of course, the above three embodiments are given for the purpose of illustration only. Any method that can distinguish color, luminance, or pattern of an image may be used. 
         [0065]    Furthermore, the set password may be text or pattern, and therefore the password input interfaces are shown as  FIG. 2  and  FIG. 3 , in which  FIG. 2  is a text input interface and  FIG. 3  is a pattern input interface. In  FIG. 3 , a pattern may be formed by connecting dots. Of course, the password input interface may also be a combination of the both. It should be appreciated that the above password setting and input methods are merely examples and any appropriate method for password setting and inputting may be used. 
         [0066]    The judging module  220  is configured to judge whether a password input by the user is matched, and if so, to have the display module  202  display an object expected by the user. If not, the user may keep trying within the predetermined number of failures (for example, 10 times). When the predetermined number of failures is reached, the judging module  220  is configured to have the display module  202  display information to prompt the user that no input is possible. At the same time, the judging module  220  is configured to have the recording module  230  record the current information comprising, but not limited to, time, location (for example, acquired via a GPS device), background (for example, acquired via the photographing module), etc. For example, the time is Apr. 16, 2012, Monday, and the location is 39° 54′ north latitude and 116° 23′ east longitude. At the same time, the transmission module  240  transmits the current information to a predetermined address in a predetermined way. The predetermined way comprises, but not limited to, any of a phone call, a voice message, an SMS message, an MMS message, an email, an instant messenger, and a social network, or any combination thereof. The predetermined address may be preset by the user or chosen from a location such as an address book. Of course, a warning may be issued in any other existing way. 
         [0067]    The objects, solutions, and advantages of the present disclosure are further detailed by the above specific embodiments. It should be appreciated that the above descriptions are merely specific embodiments of the present disclosure and not for the purpose of limiting the scope of the present disclosure. Any modification, equivalent substitution, improvement, or the like made within the spirit and principle of the present disclosure should be embraced by the scope of the present disclosure.
