Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to an information protection method. The core of the embodiment lies in detecting the motion state of the terminal equipment in real time; when the detected motion state meets a preset condition, controlling the terminal equipment to lock the screen and enter a pre-alarm state; in the pre-alarm state, when the terminal equipment is detected to execute preset sensitive operation, the data in the terminal equipment is deleted, so that when the terminal equipment is stolen and robbed, a robber cannot know the data information stored in the terminal equipment, and the possibility of information leakage can be reduced. The following describes the implementation details of the information protection method of the present embodiment in detail, and the following is only provided for the convenience of understanding and is not necessary for implementing the present embodiment.
The information protection method in this embodiment is applied to a terminal device, and the terminal device may be a mobile phone tablet computer or other terminal devices. For example, when a mobile phone holder plays a mobile phone on the road, the mobile phone holder may be directly snatched by a runaway party, and at this time, the mobile phone is not in a screen locking state, and after the runaway party directly snatches the mobile phone, the data inside can be taken without obstacles. The value of data in the mobile phone shows higher value than that of the mobile phone in the present and future, so that the protection of the data in the mobile phone from being stolen by a thief is more important. The present embodiment provides a method for protecting data in a mobile phone from being stolen by a thief, and a flowchart of an information protection method in the present embodiment is shown in fig. 1, and specifically includes:
step 101: and detecting the motion state of the terminal equipment in real time.
Specifically, the mobile phone can detect acceleration data through a built-in acceleration sensor, the motion state of the mobile phone is confirmed according to the change of the acceleration data, and different trends of the change of the acceleration data can represent different motion states of the mobile phone. Preferably, the motion state of the real-time detection terminal device can be controlled by a switch in the mobile phone, and the user can control the switch to be turned on when needed, so that the mobile phone can start to detect the motion state of the terminal device in real time, and the control switch is turned off when the motion state of the terminal device is not needed to be detected in real time, thereby achieving the effect of energy conservation.
Step 102: and when the detected motion state meets the preset condition, controlling the terminal equipment to lock the screen and enter a pre-alarm state.
Specifically, the preset conditions may be: the difference between the two adjacent detected accelerations is greater than a preset threshold, and the preset threshold can be set by a person skilled in the art according to actual needs. If the difference value of the two accelerations is large, the mobile phone is in a state of sudden acceleration, if the mobile phone is in a normal motion state, the mobile phone is considered to be in an abnormal state, for example, when a user walks on the road to use the mobile phone, the acceleration of the mobile phone is small, when the mobile phone is suddenly snatched by a flying party, the value of the acceleration is instantly increased, the difference of the acceleration values of the mobile phone before and after the mobile phone is snatched is large, if the mobile phone does not stop between normal walking and the sudden acceleration, does not get on the vehicle and the like, does not have the process of speed increase, and directly enters high-speed acceleration, the mobile phone is considered to be snatched. At the moment, the terminal equipment is controlled to lock the screen and enter a pre-alarm state, the screen is locked, so that a robber cannot unlock and steal data in the mobile phone in a short time, the pre-alarm state is a state ready for alarm, the mobile phone is indicated to enter a high-degree defense state at the moment, and if the defense state is broken, the mobile phone can immediately alarm. For example, after entering the pre-alarm state, the information of the emergency contact persons pre-stored in the mobile phone can be called, and if the pre-alarm state is broken, the alarm information can be directly sent to the emergency contact persons pre-stored in the mobile phone.
Step 103: and in the pre-alarm state, when detecting that the preset sensitive operation is executed on the terminal equipment, deleting the data in the terminal equipment.
Specifically, when the mobile phone detects a predetermined sensitive operation, the data in the terminal device can be deleted. The sensitive operation can be shutdown, card pulling, data copying and the like, and after the mobile phone is stolen, the stealer can usually perform the operations of shutdown, card pulling, data copying and the like, so when the sensitive operation is detected, the data in the mobile phone can be deleted, and the data in the mobile phone can be data stored locally in the mobile phone or data stored in an SIM card in the mobile phone.
In practical application, when deleting data in the terminal device, an alarm mechanism can be triggered, for example, alarm information can be sent to an emergency contact prestored in the mobile phone, preferably, the mobile phone can carry positioning information of the mobile phone in the alarm information and send the positioning information to the emergency contact, so that the emergency contact can search the position of the mobile phone in time according to the positioning information to know the position of a robber, and the mobile phone can be recovered. The mode of triggering the alarm mechanism can also be that a preset ring tone is automatically played at the maximum volume, and the content of the ring tone can be preset by a user, so that people around can know that the mobile phone playing the preset ring tone at present is a stolen or robbed mobile phone after hearing the ring tone. It should be noted that, the present embodiment is only an example of the above two alarm mechanisms, and is not limited to this in practical application.
Compared with the prior art, this embodiment, when real-time detection's terminal equipment's motion state satisfied the preset condition, in time control terminal equipment carries out the lock screen and gets into the warning state in advance for if terminal equipment is robbed suddenly, in the short time, the person of robbing by robbing can't carry out the unblock to the terminal equipment of robbing by robber, guaranteed the inside information safety of terminal equipment to a certain extent, get into the warning state in advance simultaneously, increased a safety defense line again for the inside information safety of terminal equipment. In the pre-alarm state, when the fact that the preset sensitive operation is executed on the terminal device is detected, the data in the terminal device is deleted, the situation that a robber attempts to steal the data in the terminal device by executing the preset sensitive operation is avoided, the possibility of information leakage is reduced, the protection of data information stored in the terminal device is facilitated, and the use safety of a user is improved.
A second embodiment of the present invention relates to an information protection method. The second embodiment is a further improvement of the first embodiment, and the main improvements are as follows: in the second embodiment of the invention, after entering the pre-alarm state, whether an unlocking instruction for the terminal equipment is detected within a preset time length is judged; if the unlocking instruction is detected within the preset time, the pre-alarm state is released, and possible misoperation is avoided.
As shown in fig. 2, a flowchart of the information protection method in this embodiment specifically includes:
step 201: and detecting the motion state of the terminal equipment in real time.
Step 202: and when the detected motion state meets the preset condition, controlling the terminal equipment to lock the screen and enter a pre-alarm state.
Steps 201 to 202 are substantially the same as steps 101 to 102 in the first embodiment, and are not repeated herein to avoid repetition.
Step 203: and judging whether an unlocking instruction for the terminal equipment is detected within a preset time length, if so, executing the step 204, otherwise, executing the step 205.
Specifically, after the mobile phone enters the pre-alarm state, the mobile phone is initially in the automatic screen locking state, and the entering of the pre-alarm state may also be triggered by the holder of the mobile phone itself, for example, the holder of the mobile phone changes from a normal walking state to a fast running state suddenly, and at this time, the detected motion state of the mobile phone also meets a preset condition, that is, the mobile phone locks the screen and enters the pre-alarm state. If the owner of the mobile phone knows the unlocking password of the mobile phone, the owner of the mobile phone can send a prompt message when the mobile phone enters the pre-alarm state, the owner of the mobile phone can unlock the mobile phone after receiving the prompt message, if the mobile phone judges that a correct unlocking instruction is received within the preset time, the step 204 can be carried out, and the preset time can be set by a person skilled in the art according to actual needs. The robber does not know the unlocking password of the mobile phone, the mobile phone enters step 205 because no unlocking command is detected within the preset time length, or the mobile phone detects an incorrect unlocking instruction within the preset time length, which may be that the robber tries to unlock, and then the step 205 is also entered.
Step 204: and releasing the pre-alarm state.
That is to say, if the pre-alarm state is triggered by the mobile phone holder, the pre-alarm state is released in time, so that the mobile phone holder can use the mobile phone conveniently.
Step 205: and in the pre-alarm state, when detecting that the preset sensitive operation is executed on the terminal equipment, deleting the data in the terminal equipment.
Step 205 is substantially the same as step 103 in the first embodiment, and is not repeated here to avoid repetition.
Compared with the prior art, the method and the device have the advantages that after the pre-alarm state is entered, whether the unlocking instruction for the terminal device is detected within the preset time is judged; and if the unlocking instruction is detected within the preset time length, the pre-alarm state is released. The unlocking instruction of the terminal equipment is detected within the preset time length, which indicates that the terminal equipment enters the pre-alarm state by some action of a holder possibly of the terminal equipment, so that the pre-alarm state is released if the unlocking instruction is detected within the preset time length, the possible misjudgment is favorably avoided, and the further use of a user is facilitated. Because the unlocking instruction is generally only known by the holder of the terminal equipment, if the unlocking instruction description is not detected within the preset time length, the terminal equipment can be stolen by a thief, and at the moment, the alarm mechanism is triggered to be beneficial to warning the thief and simultaneously the holder of the terminal equipment can find the stolen and robbed terminal equipment.
A third embodiment of the present invention relates to an information protection method. The third embodiment is a further improvement of the first embodiment, and the main improvements are as follows: in a third embodiment of the present invention, deleting data in a terminal device specifically includes: and the preset sensitive data in the terminal equipment is deleted, so that the sensitive data is prevented from being leaked.
As shown in fig. 3, a flowchart of the information protection method in this embodiment specifically includes:
step 301: and detecting the motion state of the terminal equipment in real time.
Step 302: and when the detected motion state meets the preset condition, controlling the terminal equipment to lock the screen and enter a pre-alarm state.
Steps 301 to 302 are substantially the same as steps 101 to 102 in the first embodiment, and are not repeated herein to avoid repetition.
Step 303: in the pre-alarm state, when detecting that the preset sensitive operation is executed on the terminal equipment, deleting the data of the application with the priority higher than the preset priority level.
Specifically, the deleting of the data in the terminal device may be deleting of sensitive data preset in the terminal device. The sensitive data may be data with privacy, for example, the sensitive data may be a telephone number of a family person, a file that needs to be kept secret, and the like, and the user may set which data is the sensitive data in advance. That is to say, when deleting data, the data with the relative privacy can be preferentially deleted, and other data which cannot be influenced even if being known by others can not be deleted, and the data with the relative privacy can be preferentially deleted, so that the data with the relative privacy can be rapidly deleted, and a thief can be prevented from stealing the data.
Preferably, the priority of each application of the terminal device is preset, for example, a corresponding relationship between different applications and priority levels is stored in the mobile phone, and the corresponding relationship can be set by the user according to actual needs. There are many applications in the mobile phone, and the requirements of the data stored in different applications on security and privacy are different, for example, the application binding the bank card relates to property security, the set priority may be higher, while the set priority may be lower when viewing the application of the video, and certainly in the actual application, the setting of the priority level is not limited to this. It should be noted that the information of the contact stored in the address book may also be preset with a priority, for example, the information of the family is higher in priority, and the priority of the infrequently contacted person is lower. When detecting that the preset sensitive operation is executed on the mobile phone, the priority of each application in the mobile phone can be obtained, the data of the application with the priority higher than the preset priority level is deleted, and the preset priority level can be set by a user according to actual needs.
Compared with the prior art, in the embodiment, because the data of the application with the priority higher than the preset priority level is usually more sensitive and valuable and is the data which is least likely to be leaked by the terminal equipment holder, the data of the application with the priority higher than the preset priority level is deleted, so that the data of the application with the higher priority level can be deleted quickly in a short time, and further, safety guarantee is provided for the information safety of a user.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
