Detailed ways

The gist of the present invention is to overcome the deficiencies of the prior art and provide a lock screen unlocking method and system based on application icons. The present invention adopts a random password unlocking method. After the terminal device, such as a mobile phone is turned on, a message will appear on the screen. A group of app icons in a chaotic order. This part of the icons in the chaotic order includes the icons of the installed apps obtained through the system, as well as the preset icons used to create confusion, and these icons are unlocked by random numbers. For the application icons that need to be matched, the user can unlock them only when he finds out the real application icons of all the mobile phones included in the given group of icons, and the security is greatly improved. And only mobile phone users are the most clear about the applications installed on their mobile phones, and as the use time of the mobile phone increases, the password library will be updated and expanded in time, mobile applications are constantly added and deleted, and the randomness of the passwords is very large. the

The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention. the

The method flow chart of the present invention is shown in Figure 1, a lock screen unlocking method based on application icons, which is applied to terminal equipment, where the terminal equipment includes mobile terminal equipment such as notebook computers, palmtop computers, and mobile phones, and of course can also be used for Unlock the lock screen of a desktop computer or other control devices. The lock screen unlocking method of the application icon of the present invention comprises the following steps:

Step 1. Obtain the application program installed on the terminal device, set the application program icon library, define it as a password icon library, set a random number generator, randomly generate the number N of application icons required for unlocking, and associate the random number generator with the password icon library; The application program installed on the terminal device in the present invention refers to the application program that has been installed. For example, according to the needs, the user will install a series of application software for surfing the Internet, games, entertainment, chat, or other antivirus software; A password icon library is also set up to store the icons of the application programs, that is, the icons of applications such as Internet access, games, entertainment, and chats installed by the user are all stored in the password icon library; in order to call the application icons of the password icon library, set A random number generator, which is associated with the password icon library, can randomly generate the number of application icons required for unlocking according to needs, for example, the number of application icons can be set to N, for example, N is set to 1-10, of course You can also set an upper limit T, in order to prevent the user from inputting too large a value and there will be no responsive application icons in the password icon library, and set 1<=N<=T; after associating the random number generator with the password icon library , randomly generated icons are displayed on the unlock interface as needed.

As a preferred embodiment of the present invention, the password icon library described in step 1 of the present invention is not fixed, but increases or decreases according to the application programs installed in the terminal device. And a monitoring unit is added here for detecting the list of installed application programs. That is to update according to the applications installed on the terminal equipment, including:

Step S101. The detection unit monitors in real time whether the list of applications installed on the terminal device has increased or decreased. The application list can clearly and straightforwardly show whether the user has newly installed or deleted which applications. If the application list has changed, go to the next step, otherwise Continue real-time monitoring until there is a change in the application image list before proceeding to the next step;

Step S102. It is detected that the newly installed application icon on the application program list is added to the password icon library, and the icon of the deleted application program is also correspondingly deleted from the password icon library. By updating and adjusting the password icon library, the user can more Accurately unlock the lock screen interface, but also in order to be consistent with the installed applications.

Step 2. is set to confuse the icon consistent with the desktop picture size of the terminal device, and is defined as the confuse icon storehouse; In the present invention, in order to achieve better secrecy effect, other users can not be unlocked quickly, step 2 is provided with the confuse icon, and The confusing icons include icons of uninstalled application programs or icons of installed application programs after image processing is performed. Uninstalled application icons are real application icons, but they have not been installed. Only the user knows which programs have been installed and which programs have not been installed in the terminal device, so adding uninstalled application icons can better achieve Secrecy effect. On the other hand, the icon of the installed application program icon after image processing means that the application program is already installed. technology to generate confusing icons with high similarity. By setting these two confusing icons, the difficulty of unlocking the lock screen is increased, the security performance of unlocking is improved, and the fun and experience of unlocking the user are increased. the

As a preferred embodiment of the present invention, the confusing icon library described in step 2 of the present invention is not fixed, but is added according to the application programs installed in the terminal device. Different from the password icon library, the obfuscation icon library generally only increases the obfuscation icon, and does not reduce it. However, if the application program in the application icon part that is not installed becomes the installed program, it will be deleted accordingly. Therefore, the confusing icon library described in step 2 of the present invention is updated according to the update of the application icon library, specifically including:

Step S201. Real-time monitoring whether the list of applications installed on the terminal device increases, if yes, execute the next step, otherwise continue real-time monitoring;

Step S202. Perform image processing on the application program icons, and process the installed application program icons into confusing icons with high similarity through image micro-processing technology;

Step S203. Save the processed application icon to the obfuscated icon library;

Step S204. Judging whether the newly added application program icon in the application program list exists in the obfuscation database, if yes, delete it, otherwise end the judgment.

The present invention increases the difficulty of unlocking the lock screen by further adjusting the confusing icon library. the

Step 3. Set the number M of icons required for unlocking the terminal device. The icons include application icons and confusing icons. N application icons are randomly generated from the password icon library, and M-N confusing icons are generated in the confusing icon library to form an icon unlocking interface. To set up a more complex and interesting lock screen unlock interface, N-long application icons are randomly generated in the password icon library of the present invention (the number previously set in the random number generator is N), and M-N confusing pictures are generated in the confusing icon library. According to the random arrangement and fusion, it can be a random array or a grid array, such as nine grids, 16 grids, etc. Of course, in order to achieve better results, the above arrays can be displayed on at least one page, such as two pages, three pages, etc. page is displayed. It can be set according to the specific situation and displayed on different lock pages, and the user only needs to slide the unlock interface to unlock it. the

Step 3 concrete implementation flowchart of the present invention is as shown in Figure 2, and step 3 specifically comprises:

Step S301. Obtain the number M of icons required for unlocking the terminal device. For example, M here is 16, which can form a 16-square grid. Of course, the present invention is not limited to this, and other single digits or 12, 13, etc. can be set randomly array;

Step S302. The random number generator randomly generates N application icons from the password icon library, assuming that the user sets N to 6, then the random number generator selects 6 application icons from the password icon library to prepare for calling the icon unlock interface;

Step S303. Randomly generate M-N confusing icons from the confusing icon library, if the password icon library sets N=6 application icons, then automatically generate M-N from the confusing icon library, that is, 16-6=10 confusing icons, and Device icon unlock interface call;

Step S304. Arrange the obtained M icons into an array to form an icon unlocking interface. According to the above steps, 6 application icons and 10 confusing icons form 16 grids, or form a random array, which is set according to user needs or preferences. .

Step 4. Obtain whether the application icon mark on the unlocking interface of the terminal device meets the unlocking conditions. If yes, the unlocking is successful; otherwise, it is determined that the unlocking has failed, and the unlocking interface is re-entered. The present invention sets the unlocking condition, that is, the user marks the application icon to unlock, and in order to remind the user, a prompt will be displayed on the unlocking interface, please mark the application program. the

The unlocking conditions described in step 4 of the present invention can be implemented in the following two ways. Of course, step 4 of the present invention is not limited to the following unlocking judgment methods, and any other alternative and identical unlocking interfaces are within the protection of the present invention. the

Example 1

The unlocking condition of Embodiment 1 is: all the marks are password icons, and the number of marks is equal to the number N of randomly generated application icons.

Step 4 specifically includes:

Step S4011. Acquire the marked icon type and number of icons on the unlocking interface of the terminal device; because other users except the user do not know how many password icons are on the unlocking interface, so when the user finishes marking, start counting the icon type and the number of icons; of course , for accurate statistics, set a time interval, for example, after a certain period of time after the user marks the last one, the icon type and number of icons will be automatically counted;

Step S4012. Judging whether there is a confusing icon in the icon mark, if it is judged as unlocking failure, otherwise continue to the next step; the judgment standard set in this embodiment is relatively strict, as long as other users record a confusing icon wrongly, then it is judged as If the unlock fails, if there is no confusing icon in the mark, then proceed to the next step to determine the number of mark icons;

Step S4013. Compare the number of markers with the number N of randomly generated application icons, and compare with the number N of randomly generated application icons after the number of markers is obtained by the system;

Step S4014. If the number of marks is equal to the number N of application icons, unlocking is performed; otherwise, it is determined that unlocking fails. For example, if the number of marked icons is exactly N, then the unlocking is successfully performed and other operation interfaces are entered; if the number of marked icons is less than N, then it is judged that the unlocking fails.

Of course, step S4014 of this embodiment can also be:

If the number of marks reaches the preset mark threshold of the application icon, it will be unlocked. Otherwise, it will be judged that the unlocking has failed. This setting is for more flexibility. It is more troublesome to reinstall the system, so it is more flexible to unlock.

Example 2

Different from Embodiment 1, the unlocking conditions set in Embodiment 2 are slightly looser, and confusing icons can be allowed, but the confusing icons must be within the allowed range, and the number of marks of password icons must reach a certain threshold, that is, the marks reach A certain amount can be set by the user.

Step 4 specifically includes:

Step S4021. Acquire the marked icon type and number of icons on the unlocking interface of the terminal device; because other users except the user do not know how many password icons are on the unlocking interface, so when the user finishes marking, start counting the icon type and the number of icons; of course , for accurate statistics, set a time interval, for example, the icon type and number of icons will be automatically counted after a certain period of time after the user marks the last one;

Step S4022. Determine whether there is a confusing icon in the icon mark, if yes, judge whether the number of confusing icon marks is lower than the preset threshold, if yes, execute the next step, otherwise it is determined that the unlocking failed; for example, it is possible to allow confusing icon marks 1-2 Of course, it can also be set according to the specific situation. For example, when the number of M set by the user is large, the confusion icon mark can be allowed to increase to a certain extent;

Step S4023. Comparing the number of marks with the preset password icon mark threshold; the number of marks here refers to the number of password icon marks, and the total number of marks minus the number of confusing icon marks is the number of password icon marks;

Step S4024. If the number of marks reaches the preset password icon mark threshold, unlocking is performed; otherwise, it is determined that unlocking fails. For example, there are 6 preset password icons, so as long as there are more than 4, it will be judged as successful unlocking. Of course, the present invention is not limited thereto, and the actual value is set according to user needs.

Step 4 of the present invention is not limited to the above two embodiments, and any other identical or similar unlocking condition settings are within the protection scope of the present invention. the

In addition, step 4 of the present invention further includes automatically locking the terminal device when the number of unlocking failures exceeds a preset unlocking times threshold. For example, if the user fails to unlock 5 times, the terminal device will be automatically locked, and it must reach a certain length of time before trying again, such as half an hour, one hour, etc., which can be set according to the actual situation. the

The present invention also discloses a lock screen unlocking system based on application icons, which is applied to terminal equipment, including:

The password icon library setting module is used to obtain the application installed on the terminal device, set the application icon library, define it as the password icon library, set the random number generator, randomly generate the number N of application icons required for unlocking, and combine the random number generator with the password icon library association;
