Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In the related art, application encryption technology is adopted, so that private data such as an album cannot be accessed under a file system, but a photo under an album path can still be viewed through an instruction (such as adb or shell). Therefore, the method does not really solve the privacy pain point, and the privacy data of the user still has exposure risk.
The disclosure provides a data protection method applied to a terminal. According to the method, the maintenance mode can be entered in the engineering mode, so that when after-sales maintenance is carried out, a maintenance worker can enter the maintenance mode under the condition that a preset password of the terminal is not known, in the maintenance mode, main space data of the terminal is in an encrypted state, the space data of the terminal is subjected to individual access, and when the maintenance mode enters the main space mode, a correct preset password needs to be input, so that exposure of privacy data of a user is better avoided, privacy pain spots are thoroughly solved, after-sales maintenance is more convenient, and use experience is improved.
In one exemplary embodiment, a data protection method is provided and applied to a terminal. Referring to fig. 1, the terminal is based on the android system. The method comprises the following steps:
s110, controlling the terminal to enter a maintenance mode based on the control information when the terminal is in an engineering mode, wherein in the maintenance mode, the personal space data created in the terminal is accessed, and the main space data of the terminal is encrypted;
s120, when the maintenance mode enters a main space mode, sending prompt information for inputting a preset password;
and S130, if the received input password is determined not to be matched with the preset password, controlling the terminal to be in a maintenance mode.
In step S110, the engineering mode refers to a Recovery mode in the android system, and is a mode that can modify data or a system inside a terminal (e.g., a mobile phone). Generally, when the terminal is in a power-off state, the terminal can enter an engineering mode directly by a key combination mode without inputting a password.
For example, when the terminal is in the power-off state, the volume "+" key and the power key are pressed at the same time, and the terminal can enter the engineering mode after being pressed for 3 seconds.
For another example, when the terminal is in the power-off state, the volume "-" key and the power key are pressed at the same time, and the terminal can enter the engineering mode after being pressed for 3 seconds.
For another example, when the terminal is in a power-off state, the volume "+" key, the Home key (the key of the terminal returning to the main interface) and the power key are pressed at the same time, and after the terminal vibrates, the power key (the volume "+" key and the Home key are continuously pressed) is released, so that the engineering mode can be entered.
It should be noted that different terminals enter the engineering mode in different ways, which is not described herein.
In step S110, an entrance for entering a maintenance mode is provided in the engineering mode of the terminal, and after the terminal enters the engineering mode, a user can enter the maintenance mode through the entrance.
For example, referring to FIG. 1a, in the engineering mode, the display interface of the terminal is designed with an option "enter after-sales service mode", and the user selects the option to enter the service mode.
In step S110, after the terminal enters the maintenance mode, the relevant person (e.g., the maintenance person) can only access the personal space data, and the main space data is in an encrypted state and cannot be accessed. The body-separated space data refers to data of a body-separated space created in a maintenance mode, and the data of the body-separated space can be set as data that must be used when the terminal is maintained. The main space data refers to data of a main space when a user normally uses the terminal, and the part of data mainly comprises data of a third application program and data related to user privacy, such as photos, videos, short messages, address lists, instant chat data, payment data and the like.
It should be noted that, the user can set the accessible personal space data and the encrypted main space data by himself, so that the user can set the necessary data to be in the access state according to the maintenance condition required by the terminal, and set other data to be in the encrypted state, so as to better adapt to different maintenance conditions, and further improve the user experience.
In the maintenance mode, the main space data may be encrypted by a file-level encryption technique, that is, the main space data may be encrypted by a file-level encryption technique (FBE), and all the main space data may not be accessible before decryption. In the method, the sub-space is created for the maintenance mode, the main space data is encrypted, the main space data cannot be accessed from the sub-space under a file system, the main space data cannot be accessed through adb or shell, the hidden danger that the main space data is accessed by a non-main space (sub-space) is thoroughly avoided, and the protection strength of the user privacy data is improved.
In step S120, when the maintenance mode needs to enter the main space mode, the terminal sends a prompt message for inputting a preset password. The preset password may be an unlock password, a power-on password, or the like of the terminal, or may be a password separately set for exiting the maintenance mode, or a password separately set for entering the main space mode, and a specific form of the preset password is not described herein.
In step S130, after the relevant person inputs the password, the terminal receives the entered password input by the relevant person, and if the entered password is not matched with the preset password, that is, the entered password is inconsistent with the preset password, the control terminal is still in the maintenance mode, so that other persons can be better prevented from exiting the maintenance mode, the exposure of the private data of the user is better avoided, and the data protection intensity is further improved.
It should be noted that if it is determined that the entered password is matched with the preset password, that is, the entered password is consistent with the preset password, the terminal is controlled to exit the maintenance mode, and the terminal enters the main space mode.
According to the method, when the terminal is maintained after sale, maintenance personnel can directly enter a maintenance mode from an engineering mode without knowing a preset password of the terminal, and in the maintenance mode, the personal space data is accessed and the main space data is encrypted, so that the maintenance of the maintenance personnel is facilitated, the private data of a user can be better prevented from being leaked, and the use experience of the user is improved.
In one exemplary embodiment, a data protection method is provided and applied to a terminal. According to the method, when the terminal is restarted in a maintenance mode, the terminal is controlled to enter the maintenance mode.
That is, when the relevant person restarts the terminal while the terminal is in the maintenance mode, the terminal still enters the maintenance mode.
It can be understood that in the process of after-sales maintenance, the terminal in the maintenance mode may be shut down due to insufficient electric quantity, and in this state, the terminal is restarted after being charged in time, and still enters the original maintenance mode, so that the leakage of the privacy data of the user can be better avoided.
In the method, as can be seen from the steps S120 and S130 in the above exemplary embodiment, once the terminal enters the maintenance mode, the maintenance mode must be initiated by inputting the preset password, and the main space mode is entered. In the after-sale maintenance process, the maintenance personnel do not know the preset password, so that the method can well enable the maintenance personnel to finish maintenance and well protect the privacy data of the user in the after-sale maintenance process.
In one exemplary embodiment, a data protection method is provided and applied to a terminal. The method further comprises the following steps:
and deleting the current maintenance data when the maintenance mode is exited, wherein the current maintenance data refers to the maintenance data generated in the maintenance mode.
In the method, after the maintenance is finished, a user can push out the maintenance mode by inputting the preset password, and when the maintenance mode is pushed out, the current maintenance data generated by the maintenance is deleted, so that the occupation of the maintenance data on the memory of the terminal can be well avoided, the accumulation of the maintenance data can be well avoided, and the performance of the terminal is ensured.
In one exemplary embodiment, a data protection method is provided and applied to a terminal. In the method, entering a maintenance mode based on the control information comprises:
s210, determining to start a maintenance mode based on the control information, and detecting whether a preset password exists or not; if the preset password is determined to exist, executing step S230; if it is determined that the preset password does not exist, performing step S220;
s230, outputting prompt information for setting a preset password, and executing the step S230 after the preset password is determined to be set;
and S240, controlling the terminal to restart so that the terminal enters a maintenance mode.
In step S210, the control information refers to information for determining that the maintenance mode is turned on. The control information may include only a single piece of information or may include a plurality of pieces of information, that is, the control information may refer to a set of information.
In the case of example 1, the following examples,
referring to fig. 1a, the control information is single information. An option button for entering an after-sale maintenance mode is arranged in an engineering mode of the terminal, and after a user clicks the option button, the terminal can receive corresponding control information and determine to start the maintenance mode.
In the case of example 2, the following example was carried out,
referring to fig. 1a to 1d, the control information is a set of information, and includes first sub-control information, second sub-control information, third sub-control information, and fourth sub-control information in sequence. An option button for entering an after-sale maintenance mode is arranged in an engineering mode of the terminal, after a user clicks the option button, the terminal can receive first sub-control information of a response, and the terminal enters a prompt interface for starting the maintenance mode based on the first sub-control information.
The prompt interface can include: the maintenance mode may have an achievable effect (e.g., private data of the user may be protected), a prompt to remind the user to backup important data in advance, an option button to confirm an exemption protocol, an option button to turn on the maintenance mode, and so on. The related personnel can know the function of the maintenance mode, the possible risks and the like through the prompt interface.
And the user clicks the option button for confirming the exemption protocol, the terminal can receive the second sub-control information, confirm that the exemption protocol is confirmed by the related personnel, switch the option button for starting the maintenance mode into a highlighted state and remind the user that the option button is in a selectable state at the moment.
The user can click the option button in the highlight state, the terminal can receive the third sub-control information, a display interface of the control terminal pops up a popup window for opening the maintenance mode, the popup window prompts that the maintenance mode needs to be started and the terminal needs to be restarted, and an option button for determining to immediately start the maintenance mode is provided.
The user can click the option button of 'open immediately', the terminal can receive the fourth sub-control information, control the terminal to restart, and enable the terminal to enter a maintenance mode after restarting.
In step S210, after determining to start the maintenance mode, the terminal detects whether a preset password exists. The preset password may be a power-on password of the terminal. And controlling the terminal to enter different processes according to the detection result. The detection method of the preset password is not described herein.
As an example of this, it is possible to illustrate,
the control information is a group of information, and sequentially comprises first sub-control information, second sub-control information, third sub-control information and fourth sub-control information. When the terminal is controlled to restart based on the fourth sub-control information, the terminal detects whether a preset password exists or not, and then the terminal is controlled to enter different processes according to a detection result.
In the method, when the preset password is determined to exist, the step S230 is directly entered, the terminal is controlled to restart, the restarted terminal enters a maintenance mode, and the setting of the maintenance mode is completed. When the preset password does not exist, outputting prompt information for setting the preset password, wherein the prompt information may include a password input interface for setting the preset password. After the user sets the preset password, the terminal may determine that the preset password is set, and then the method proceeds to step S230, and controls the terminal to restart, so that the restarted terminal enters the maintenance mode to complete the setting of the maintenance mode. The specific setting mode of the preset password and the specific form of the preset password are not described herein.
In one example, the preset password is a power-on password or an unlock password of the terminal. Generally, users set a power-on password or an unlocking password. When the user sends the terminal to after-sale to be maintained, maintenance personnel can directly enter a maintenance mode from an engineering mode without knowing a preset password, and the terminal is maintained. Furthermore, since the maintenance staff does not know the preset password, the maintenance staff cannot enter the main space mode and cannot acquire the private data (main space data) of the user.
After the maintenance is finished, the preset password is the starting password or the unlocking password which is set in advance by the user, so that the user can exit the maintenance mode and enter the main space mode to normally use the terminal by inputting the preset password when taking the terminal.
The method can well solve the problem of private data exposure in the after-sales maintenance process, is convenient for maintenance personnel and users, and improves the use experience.
In one exemplary embodiment, a data protection method is provided and applied to a terminal. In the method, before determining to start the maintenance mode, the method further comprises:
s310, detecting whether old maintenance data exist or not;
and S320, if the old maintenance data exist, deleting the old maintenance data.
The old maintenance data refers to the maintenance data which is generated in the last maintenance mode and cannot be deleted, and if the maintenance mode needs to be started for the first time, the last maintenance mode does not exist, and certainly, the old maintenance data does not exist.
In this method, although the current repair data is deleted each time the repair mode is exited, there is a possibility that the data may not be completely deleted or may be directly flashed back due to some reason. Therefore, when the maintenance mode is started each time, whether old maintenance data exist needs to be detected, and if the old maintenance data exist, the old maintenance data are deleted, and then the maintenance mode is determined to be started, so that the leakage of the old maintenance data is avoided.
The method can also set a preset time length, and if the old maintenance data is not deleted within the preset time length, the failure of opening the maintenance module is determined. That is, if the old maintenance data is not completely deleted within the preset time period, the maintenance mode is not started, and the step of "determining to start the maintenance mode" is not performed.
Illustratively, if the maintenance mode is failed to be started, the terminal is controlled to restart, so that the terminal is restored to the previous state, such as a screen locking state.
It is supplementary to be noted that if it is determined that there is no old maintenance data, it may be determined to start the maintenance mode according to the control information.
In the method, when the maintenance mode is started, whether old maintenance data exist needs to be detected, and the maintenance mode is determined to be started only after the old maintenance data do not exist or are deleted completely, so that the leakage of the old maintenance data is avoided, and the protection strength of the privacy data of a user is further improved.
In one exemplary application scenario, such as an after-market repair scenario.
When a user needs to maintain the mobile phone, the mobile phone can be directly sent to an after-sales maintenance center, and when a maintenance worker of the after-sales maintenance center maintains the mobile phone, the user does not need to need a password, the mobile phone can directly enter an engineering mode by a key combination mode, and then the mobile phone is maintained by entering the maintenance mode in the engineering mode.
When the terminal is in a maintenance mode, the body-separated space provides necessary body-separated space data for maintenance, the partial data is accessed, and maintenance personnel can perform maintenance based on the body-separated space data. The main space data of the main space is encrypted by adopting a file-level encryption technology, and if no password is preset, maintenance personnel cannot access the encrypted main space data, so that the privacy data of users are protected.
Also, when exiting the service mode, a password needs to be entered. After the terminal acquires the input password input by the related personnel, if the input password is inconsistent with the preset password, the mobile phone is controlled to be in the maintenance mode continuously, so that the situation that people without knowing the preset password check the main space data is avoided.
In addition, when the terminal is in the maintenance mode, the mobile phone is still in the maintenance mode after being restarted, so that the situation that the mobile phone is restarted to exit the maintenance mode is better avoided, and privacy data of a user can be better protected.
The method can well protect the private data of the user. Especially for after-sale maintenance in a sending mode, maintenance personnel can complete maintenance under the condition of not knowing a preset password conveniently, and privacy data of a user can be prevented from being leaked.
