detailed description

In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The basic method of the present invention includes: registering the language symbol used for unlocking in the electronic device; when the electronic device needs to be unlocked, receiving the input language symbol and comparing it with the registered language symbol, and unlocking the electronic device when the comparison result is consistent .

On the basis of the above basic method, various strategies for parsing language symbols can be added as needed, such as rotation strategy, stroke correction strategy, fuzzy matching strategy, etc., and the set strategy can be used to more effectively identify the language symbols input by the user. Unlocking of electronic devices.

In addition, corresponding to different users, the language symbols used to unlock the electronic device can be registered separately; the electronic device compares the input language symbols with the registered language symbols of different users, and can determine the use of users of electronic devices, thereby realizing personalized settings for multiple users.

At the same time, the analysis of the input language symbols by the electronic device can be used to identify the positive use of the electronic device, thereby overcoming the disadvantages of relying on the gravity sensor to identify the positive use.

The specific implementation manner of the present invention is illustrated below through specific examples.

FIG. 1 is a flowchart of an unlocking method for an electronic device in an embodiment of the present invention. As shown in Figure 1, the method includes:

Step 101, setting the strategy and corresponding parameters for language symbol analysis when unlocking the electronic device.

As mentioned above, in order to recognize the input language symbols more effectively, various parsing strategies can be set as required. Of course, in the simplest way, it is also possible to directly perform step 102 to register language symbols without setting a policy. This step gives some practical analysis strategies, which will be explained one by one below. Of course, these policies can also be directly set in the electronic device as a default setting, which does not require additional selection and setting by the user.

1. Rotation strategy

Set the adopted rotation strategy and set the rotation angle. After adopting the rotation strategy, when the user subsequently needs to unlock the electronic device to input language symbols, the electronic device can recognize the language symbols inputted at an angle within the set rotation angle range, so that the electronic device can analyze the input at an angle.

2. Stroke correction strategy

The stroke correction strategy includes but is not limited to the correction of the stroke direction and the splicing of basic strokes. When the user enters smoothly, the order of stroke input is similar to that of normal input. However, when the input conditions are limited, stroke input in different directions will appear. For example, the strokes are originally from left to right, but the user When inputting, it is input from right to left. When the stroke direction is corrected, all basic input strokes can be corrected and converted into normal direction strokes; when the basic strokes are spliced, different strokes input in consecutive strokes can be recognized.

If there is the above-mentioned need for stroke correction, you can set the stroke correction strategy in this step, and you can also set specific correction content, such as stroke direction correction, basic stroke splicing correction, etc.

3. Fuzzy matching strategy

The fuzzy matching strategy means that for the language symbols input by the user, select some of the language symbols to compare with part of the registered language symbols, and unlock if they are consistent, regardless of whether other language symbols are consistent with the registered language symbols. For example, the first word is set for fuzzy matching, and the electronic device matches the first language symbol input by the user with the first registered language symbol, and unlocks if successful.

If there is a need for the above-mentioned fuzzy matching, a fuzzy matching strategy can be set in this step, and some language symbols used for fuzzy matching can be set. The system can provide multiple alternatives, which can be selected and set by the user.

In addition, corresponding to fuzzy matching is an accurate matching strategy, which is to compare all the language symbols input by the user with all the language symbols registered by the user, and unlock if they match. That is the comparison mode given in the basic method of the present invention.

4. Mix and match strategy

In order to further improve security, the fuzzy matching strategy can also be combined with the exact matching strategy, that is, the mixed matching strategy. After the mixed matching strategy is set, when the electronic device analyzes the input language symbols, it can preferentially adopt the fuzzy matching strategy to identify the input language symbols. If the matching is unsuccessful, the electronic device provides the user with a choice of multiple language symbols, allowing The user selects the language symbol, and then decides whether the input content is consistent with the registered language symbol.

5. Judging the positive direction of equipment use

When the electronic device has two or more forward directions, the language symbol unlocking can be used to judge the forward direction of the device. In this step, it can be set to use the unlocking process to determine whether the device is being used correctly.

When this policy is set, the electronic device does not need to use the gravity sensor to determine the direction in which the device is used, but when the electronic device recognizes the language symbols input by the user, the input language symbols will be recognized from the forward direction of the device. Analyze and compare the registered language symbols. If the language symbols are successfully recognized in a certain direction, the device is unlocked, and this direction is set as the current positive direction of the electronic device. In some embodiments, the device has multiple directions for use. The device uses the gravity sensor to tell the direction of the device. The user inputs the language symbol, and the engine recognizes the language symbol. If the recognition is successful, the device is unlocked and the current direction is set to use Positive.

In order to enable multiple users to use the same electronic device, a multi-user policy can be set and adopted, which is specifically divided into a multi-user equal authority policy and a multi-user unequal authority policy.

6. Multi-user and other authority policies

Under equal authority, different users can switch to their own use environment by inputting their own registered language symbols.

7. Multi-user unequal authority policy

The multi-user unequal permission policy is relative to the multi-user and other permission policy, and specifically refers to that the electronic device has multiple users, but the permissions of these users are unequal. For example, users with low privileges have limited access to the network with devices, or limited usage time. When a low-privilege user touches the border to access, the device enters the screen lock, or the device records the process for the high-privilege user to view, or directly enters the lock screen state, and reactivating the device can only be completed by the high-privilege user. Or, the time that a low-privilege user can use the device is limited. When the user uses the device for a time that exceeds the limit, the device can enter a locked screen or other locked state, and reactivation of the device can only be done by a high-privilege user.

If there is the above-mentioned need for multi-user management, you can set the multi-user equal authority policy or the multi-user unequal authority policy in this step according to the needs. After setting the multi-user unequal authority policy, you need to further set the access of different users permission.

The above are several practical strategies provided by the present invention, and one or more strategies can be selected according to needs.

Step 102, registering the language symbol used for unlocking.

Ways to register language symbols include but are not limited to soft keyboards, hard keyboards, handwriting input, audio input, and other sensor inputs. The registered content can be any content of the language symbol, and the content is limited by the engine unit used for parsing the language symbol, and the symbol that the engine unit cannot recognize cannot be registered. Of course, if the engine unit of the language symbol supports dynamic update, the registered language symbol can also be expanded accordingly. The electronic device can save the registered language symbol and the multiple strategies set in step 101 in the engine unit, or save them separately. Registered language symbols can be saved on the local device or in a distributed environment.

Among them, the strategies related to language symbol analysis set in step 101, such as rotation strategy and stroke correction strategy, can be applied when registering language symbols in this step.

In addition, if a multi-user strategy is adopted, when registering language symbols in this step, corresponding to different users, respective language symbols can be registered for unlocking. In this way, when the subsequent user inputs language symbols to unlock, the electronic device can sequentially compare the input language symbols with the registered language symbols of each user, and when they are consistent, unlock the electronic device and determine the user to whom the consistent language symbols belong The electronic device is switched to the user's use environment.

Step 103, when unlocking is required, the electronic device receives the input language symbols, and performs symbol analysis according to the set strategy.

The electronic device receives the language symbols input by the user, specifically, the input language symbols may be received through a touch screen or a touch pad. As mentioned above, the input language symbol should be able to be recognized by the language symbol engine unit. The specific input direction is related to the strategy of the electronic device. The language symbols input by the user received in this step can be one or more symbols. In some embodiments, in order to distinguish the continuity and independence of language symbols, the electronic device can provide the user with a specific UI to better distinguish Divide multiple symbols entered by the user. For example, the input interface of the electronic device can be divided into areas, assuming that it is divided into three blocks, and each block allows one word to be input, and then the whole word is analyzed and compared with the registered word.

If a strategy for parsing language symbols is set in step 101, such as rotation strategy, stroke correction strategy, etc., when parsing the input language symbols in this step, it needs to be analyzed in combination with the previously set strategy.

If the setting adopts the rotation strategy, then the rotation angle set in step 101 needs to be read for parsing the input language symbols. In some embodiments, the rotation strategy can be dynamic, and the rotation strategy can be directly implemented when registering (that is, as mentioned above, the rotation strategy is applied to the registered language symbols for identification), and the rotation can also be implemented when unlocking strategy, the electronic device allows the user to turn off the rotation strategy. Specific closing and opening rotation strategies can be implemented in both software and hardware ways.

For the case where the rotation strategy is adopted, a UI matching the rotation angle can pop up on the authentication interface that requires input of language symbols to unlock the device, and cooperates with the user to enable the input of language symbols for unlocking in all directions. For example, the UI interface is divided into several areas, and different areas correspond to different rotation angles. Users input language symbols in convenient areas. When electronic devices read language symbols, they will receive language symbols according to the rotation angles corresponding to the areas where they are located. Rotate and compare. Or, in some applications, it can also start from 0 degrees, and then compare and judge with the registered symbols by increasing the angle. The above two methods of authentication are operated from the set point of view.

If the stroke correction strategy is set, the electronic device will adjust the stroke order of the language symbols input by the user, so as to distinguish the language symbols more accurately. This strategy is useful for recognition of symbols when they are input by the non-dominant hand. Among them, the correction of the stroke direction is to correct all the basic input strokes, such as horizontal, vertical, left, and right; if the stroke direction correction is not set, then when unlocking, some input method engine units cannot perform it. If it is recognized correctly, if some input method engine unit can recognize it, then the input feature of the stroke can also be used as a feature to unlock the specific input content. For the splicing of strokes, it can be said that it is a problem that occurs during the continuous stroke input process. For example, when inputting the word "Ren", continuous strokes appear on the radical and the right half. When registering language symbols, this feature can also be selected. Unlock authentication At this time, the unlocking judgment can be carried out in combination with the continuous stroke feature and the specific content of the input.

An example of stroke correction is given below. As shown in Figure 2, 2A and 2B are non-standard stroke input, and 2C is standard stroke input. In this figure 2, 2A and 2B have the same input content, the difference between the two is that 2A01 and 2B01 have different writing directions, and 2A02 and 2B02 have different writing directions. In some embodiments, 2A and 2B may also have different stroke directions, but the meaning of the input content is the same.

2C is a standard stroke input after 2A and 2B correct strokes. The processed content of 2C is the parsed language symbol, which should be easy for the engine unit to recognize, so that 2A and 2B have the same processing result.

In some cases, when registering the symbols recognized by the device, the stroke order of the symbols can also be used as the recognition feature. When identifying symbols, extract the sequence of strokes, analyze the symbols, get the result, and then compare the registered symbols with the sequence of strokes to determine whether to unlock.

After the electronic device parses the language symbol according to the set strategy, it is used for the comparison operation in step 104 .

In addition, when analyzing the input language symbols, it may also be performed according to the parameters of the gravity sensor. Specifically, when the gravity sensor can directly provide the current vertical orientation (this situation often occurs when the user unlocks the device vertically, not in landscape or portrait), it can be assumed that the sensor determines that the current orientation is used. Linguistic symbols can then be recognized in conjunction with the forward direction instead of using the angle of rotation.

Step 104, compare the language symbol analyzed in step 103 with the registered language symbol, and unlock if they are consistent.

The parsed language symbol is compared with the registered language symbol. The usual comparison method can be to perform a correlation operation on the two. When the correlation meets certain conditions, the two are considered to be consistent, otherwise the two are considered to be inconsistent. Usually the comparison operation is performed by the engine unit of the language symbol, and the comparison result is given. When the comparison result is inconsistent, the electronic device may further analyze the input language symbols according to other set policies, or determine that the unlocking fails.

If the fuzzy matching strategy is set in step 101, the electronic device provides the user with a method of implementing the fuzzy matching strategy on the lock screen interface, and prompts the user to input the correct partial language symbols to unlock the electronic device. These methods include, but are not limited to, audio, text, and other content. In this case, when comparing the parsed language symbols with the registered language symbols in this step, determine the preset partial language symbols used for fuzzy matching, and select the part used for fuzzy matching from the language symbols input by the user The language symbol is compared with the language symbol used for fuzzy matching in the registered language symbols, and whether to unlock is judged according to the comparison result. For example, it can be unlocked by prompting the user that the first symbol input by the user is correct. In this step, when comparing, the first symbol input by the user is compared with the registered first symbol, and if they are consistent, the unlock is performed.

If the exact matching policy is set in step 101, then the electronic device should be able to provide a method for the user to implement the exact policy on the lock screen interface. These methods include but are not limited to audio, text and other content. During the comparison in this step, in some embodiments, multiple alternative language symbols may be provided to the user based on the analysis of the language symbols input by the user, and the language symbols selected by the user are compared with the registered language symbols, Determine whether to unlock according to the comparison result.

If the mixed matching strategy is set in step 101, then when the electronic device compares in this step, it first compares whether part of the language symbols are consistent with the registered language symbols according to the fuzzy matching strategy, and if the unlocking conditions for fuzzy matching are met, then Unlock directly; otherwise, according to the analysis of the language symbols input by the user, provide the user with multiple choices, compare the language symbols selected by the user with the registered language symbols, and finally determine whether to unlock according to the comparison result.

In some cases, as mentioned above, when the user registers the symbol, the stroke order and direction of the language symbol can also be saved as the characteristics of the registered language symbol. In this case, when judging whether to unlock in this step, it is also necessary Determine whether the stroke sequence of the input symbols is consistent with the parameters saved during registration.

If it is set in step 101 that the use of the unlocking process is used to determine the forward use of the electronic device, then when analyzing and comparing the input language symbols in step 103 and this step, the analysis is performed according to each alternative use of the electronic device, and compared with registered language symbols for comparison. If the parsed language symbol in a certain candidate direction is consistent with the registered language symbol, then this direction is set as the currently used forward direction of the electronic device. When the analysis results of the input symbols according to each alternative usage direction are inconsistent with the registered language symbols, re-enter the lock screen state or use other modes of unlocking. Wherein, when analyzing a plurality of alternative use forward directions, the analysis of each alternative use forward direction may be performed serially or in parallel.

Furthermore, if the rotation strategy is set before, when the application unlocking process determines the forward use of the electronic device, it is necessary to distinguish the analysis range of multiple alternative forward use of the device, that is, centering on the direction of the alternative forward use, in In the range corresponding to the rotation angle, it is necessary to analyze the input language symbols.

Specific examples are given below. Fig. 3a and Fig. 3b are schematic diagrams for judging whether the device is used in the forward direction. Among them, 3A01 and 3B01 are the main components of electronic equipment, and this part includes software and hardware. 3A02 and 3B02 are electronic devices that accept user handwriting input and display the input content. The component may be a touch screen or a touchpad. When the component is a non-displayable area, the device will display input content in other display areas. 3A02 and 3B02 can be separated from 3A01 and 3B01 and connected by a communication method, but the input content of this part can still be analyzed and judged. 3A03 is a language symbol input by the user in a positive direction, and the engine analyzes it. In this example, the analysis result should be the word "Wang". If the device analyzes it from another positive direction, the analysis result is very likely It is the word "state". The engine can give the similarity of the two input directions, and then use the selection strategy to select, and then determine the forward direction of the device. Here, the forward direction of the device should be vertical. 3B03 is an input similar to 3A03.

The above method is very useful for electronic devices with large screens, because most of them do not use the gravity sensor to rotate conveniently to determine the applicable positive orientation like electronic devices with small screens. The above method not only realizes unlocking, but also helps users choose to use the forward direction while unlocking.

Fig. 3c is a front schematic diagram of the use of the judging device of the circular device. 3C01 is the main component of electronic equipment. This part can have a circular appearance or other shapes. The circular shape here is mainly to illustrate that the equipment can be used in multiple directions. 3C01 can use hardware or software to set the current use direction of the device, so that the device can further judge and process user input. 3C02 is a component that accepts input or displays some components. 3C03 is user input content or display content. Input content and display content can be written separately or together. The processing of the situation shown in FIG. 3c is the same as that of FIG. 3a and 3b, except that the input language symbols need to be parsed in more directions. Wherein, the rotation strategy can also be combined to analyze the input language symbols within the range of the rotation angle on the basis of a certain alternative usage direction.

If a multi-user strategy is adopted, when comparing language symbols in this step, compare the language symbols input by the user with the registered language symbols of each user in turn, and when they are consistent, unlock the electronic device and determine the user to whom the consistent language symbols belong, Switch the electronic device to the user's use environment, and start related settings for the user. The multi-user policy can be different from the multi-user policy of the operating system. When setting a user, you can select a user-sensitive application, or after the application is installed, give a user-sensitive option to set the operation method of the application when switching users. .

In addition, as mentioned above, the multi-user policy can also be subdivided into the multi-user equal authority policy and the multi-user unequal authority policy. For permission policies such as multi-user, electronic devices may be shared by multiple users, and the permissions of these users are equal, and access to applications and use of the network are independent. These users can arrange the UI of commonly used applications for convenience.

For the policy of multi-user unequal rights, the electronic device is shared by multiple users, but the rights of these users are not equal, and the use of applications, network use and device use time may also be unequal. As mentioned above, in step 101, different access rights are set for different users. When a user conducts unauthorized access, the electronic device enters the lock screen state, and/or records the unauthorized access; when the user enters the lock screen state due to the user’s unauthorized access, it can only be accessed by users with higher authority than the unauthorized access Unlock electronic devices. Specifically, if the language symbol received by the electronic device is a language symbol registered by an unauthorized access user, the electronic device will not be unlocked; if the language symbol received by the electronic device is a language symbol registered by a user with a higher authority than the unauthorized access user, then Unlock electronic devices.

For example, after a low-privileged user operates the device for a certain period of time, the device will re-enter the lock screen state. At this time, only a high-privileged user can unlock the device. After unlocking the device, the user switching of the operating system is not necessarily performed, and only the user application can be performed. switch. In some embodiments, the high-privilege user has a certain control right over the access of the low-privilege user, and he can set information about application startup, network access, and device usage time.

Furthermore, in the process of the user unlocking the electronic device, some applications can also be activated. Specifically, certain specified applications can be arranged in the input space unlocked by the user, and when the language symbols for unlocking the electronic device are input into the input space corresponding to a certain application, the corresponding application is directly activated after unlocking the electronic device. In some embodiments, language symbols can be input in a space, and application icons can also be added in this space. These specific applications can actively use the symbol input path when the user inputs in a specific position. to connect to these locations to activate these apps. For example, on an IPad, the input space can be divided into 4 areas, and each area can be unlocked with language symbols, but unlocking in different areas will correspond to different types of applications, such as games when corresponding to the first area, The second area is commonly used social applications, the third area is work type, and the fourth area is miscellaneous. In this way, enter a symbol in a certain area to unlock it, and then activate it in the space of these applications. For another example, language symbols can be input in a rectangle, and then within the rectangle, text messages, contacts, and emails can be arranged in a rectangular space that does not affect the input. When inputting language symbols in the rectangle, the input of strokes during the input process can be combined with other applications. If the icon of the application has strokes and is successfully unlocked, the application is activated. In this way, in the process of inputting symbols, not only the characteristics of free transformation of the input space are brought into play, but also the container function of the input space is fully utilized.

So far, the flow of the method in the present invention ends.

The present invention also provides an unlocking device for electronic equipment, which is used to implement the above unlocking method. Figure 4 is a schematic diagram of the basic structure of the unlocking device in the present invention.

Specifically, the unlocking device includes a registration unit, an engine unit and an unlocking unit. Among them, the registration unit is used to receive and save the language symbols registered by the user for unlocking; the input unit receives the input language symbols when the electronic device needs to be unlocked; the engine unit is used to combine the language symbols received by the input unit with the registration The language symbols saved by the unit are compared, and when the comparison result is consistent, the unlocking unit is notified to unlock; the unlocking unit is used to unlock the electronic device when the comparison result output by the engine unit is consistent.

Furthermore, in order to identify language symbols more effectively, preferably, the unlocking device may further include a language symbol analyzing unit.
