In order to make the purpose, technical solution and effect of the present application clearer and clearer, the present application is further described in detail below with reference to the accompanying drawings and examples.
The application provides a method for protecting sensitive information, which regulates and controls the protection processing of the sensitive information by monitoring the control state of an authorized user on the sensitive information. By the method, the processing efficiency of the sensitive information is improved, and the user can check the sensitive information more conveniently.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for protecting sensitive information according to a first embodiment of the present application. In this embodiment, the method for protecting sensitive information includes the following steps:
s101: the mobile device judges whether the sensitive information is in a foreground display state.
The mobile device stores various sensitive information, and all the information is not displayed on a foreground interface. When it is in the background or stored only in memory, there is a protection policy of the memory or a protection policy of the application to protect. And when the sensitive information is in a foreground display state, the sensitive information is easily seen by other people, so that the secret leakage or the embarrassment is caused. There is a need to enhance the protection of sensitive information.
S102: and if the sensitive information is in a foreground display state, judging whether the display state of the sensitive information is in a non-hidden state.
Based on the prior art, when sensitive information is displayed, the sensitive information can be hidden and real information content is not displayed in order to protect the sensitive information. The normal display (non-hidden state display) is only possible after the user authorization is verified.
S103: and if the display state of the sensitive information is a non-hidden state, detecting whether the mobile equipment is in a controllable state of an authorized user, and when detecting that the mobile equipment is not in the controllable state of the authorized user, protecting the sensitive information.
After the authorized user verifies and displays the sensitive information, the sensitive information is really displayed, and at the moment, if the authorized user leaves, the mobile equipment is in a non-supervision state, and at the moment, the information is easily peeped or photographed and stored by other people while the space is reserved, so that the information leakage is caused. On the other hand, if all the information is set to be hidden and displayed, even if the mobile device is in a user controllable state, the information needs to be verified to be displayed, for example, when the user chats in a personal room group, the user does not check the information for a while, and when the user checks the information again, one more step of verification is needed, which is not changed. Therefore, it is impossible to manage according to the actual environmental conditions.
The protection method for the sensitive information can detect and judge the control state of the user on the sensitive information, and when the protection method is in the control range of the user, the sensitive information does not need to be hidden, so that the processing flow is reduced, and the decryption flow of the user is also saved. Namely, the user can control the sensitive information not to be hidden under the condition of leakage through screen viewing. And when the sensitive information is detected to be out of the supervision of the user, hiding the sensitive information.
In one embodiment, whether an instruction for storing sensitive information is received is judged; and if the instruction for storing the sensitive information is received, the storage instruction is not responded, or the sensitive information is protected when the storage instruction is executed.
In particular, saving means that the sensitive information may be stored to other locations or saved in other ways that may be out of the user's control, so the saving instruction may be regarded as a signal that the sensitive information is about to be out of the user's control. When receiving the signal, the signal can not respond or the sensitive information can be protected when executing the saving instruction. When the saving instruction is not executed, the user can be reminded of the popup window, the user tries to save the information, whether to operate himself or herself, whether to execute the operation or not, and when the user approval is obtained, the operation is executed again. The protection processing of the sensitive information when the storage instruction is executed means that the stored information is subjected to hiding processing, real information content is not stored, and if the real information content needs to be obtained and stored, approval of a user is required.
In one embodiment, the instruction for saving the sensitive information is to capture a screen, and the protecting the sensitive information when the saving instruction is executed includes: and sensitive information is blocked, replaced or mosaiced in the intercepted screen picture. Specifically, if the sensitive information is actually displayed on the screen, the sensitive information becomes a picture form after being saved by the screenshot, cannot be modified, and is possibly leaked and transmitted, so that the sensitive information is hidden at the moment of saving the screenshot if the screenshot is not authorized by the user when the operation is performed. For example, when a screenshot chat record is captured, the sensitive information content, the head portrait of the user sending the sensitive information, the group chat name and the like can be mosaiced. User authorization is required if the real content is to be intercepted.
In one embodiment, whether an instruction for accessing sensitive information is received is judged; and judging the access authority of the access instruction, and when the visitor does not have the access authority, not responding to the access instruction or performing protection processing on the sensitive information when executing the access sensitive information instruction. In particular, the access information is aware that other users need to know the content of the sensitive information, and the sensitive information may be out of the control of the users, so the access instruction may be regarded as a signal that the sensitive information is about to be out of the control of the users. When receiving the signal, the signal can not respond or carry out protection processing on the sensitive information when executing the access instruction. When the access instruction is not executed, the user can be reminded by popup, the user is trying to access sensitive information, whether the operation is allowed or not, whether the operation is allowed to be executed or not is judged, and the operation is executed again when the user approval is obtained. The protection processing of the sensitive information when the access instruction is executed means that the information accessed by the visitor is hidden and does not display real information content, and if the real information content needs to be checked, approval of a user is required.
In one embodiment, the sensitive information is group chat information, the access authority of the access instruction is determined, and when the visitor does not have the access authority, the unresponsive access instruction includes: the sensitive information carries identification information, only the user matched with the identification information can receive the sensitive information, and other users cannot receive the sensitive information. Specifically, in group chat, each user can check group chat information in principle, but if a certain piece of information is only seen by a certain person, for example, only a certain member is informed to do a certain thing, the information can be identified, the identification can only be seen by a certain member, after the information is sent out, the information cannot be seen by other members, only one piece of information is reminded to be received, but the information content is not displayed; or does not receive the information directly. For example, the message can be transmitted with @ zhang, wherein @ zhang can be used to identify that the message reminds zhang to view, and another @ can identify that the message can only be viewed with zhang.
In one embodiment, whether a user leaves the mobile device or whether a new user joins the mobile device is detected; and when the user is detected to leave the mobile equipment or a new user is added to watch the mobile equipment, switching the display state of the sensitive information into the hidden state. Specifically, when the user leaves the mobile device, it means that if someone checks the sensitive information at this time, the user cannot prevent the sensitive information, and the sensitive information will be out of the control of the user. When this signal is received, the sensitive information is switched to a hidden state. When a new user is detected to join in watching the mobile device, if a person who steals the mobile device is standing behind the user to peep the information, the user may not find the information, and sensitive information is leaked. Whether a person approaches or leaves can be monitored by using a front camera, a sound receiver and the like of the mobile equipment; the whole environment around the user can be detected by means of an indoor camera.
By the method, the sensitive information does not need to be encrypted all the time, each piece of sensitive information does not need to be encrypted, and only the sensitive information is protected when the sensitive information is possibly checked and leaked. The information processing efficiency is improved.
In one embodiment, the protection processing on the sensitive information includes: and replacing the sensitive information with random characters by using a preset algorithm, wherein the characters used in each replacement are different. Specifically, when the special characters are used for replacement, the same characters can be used for replacing certain information or information of a certain person, so that a user can conveniently and quickly judge the information type; but this approach is easily deciphered over time; a preset algorithm can be set, and a replacement character is randomly generated for each piece of information through the algorithm; the replacing characters can be any combination of numbers, characters and special symbols; and the characters of each time of replacement are controlled to be different, so that other people can be prevented from deciphering and analyzing the sensitive information according to the encryption rule.
In one embodiment, if the sensitive information is in a hidden state, detecting whether an instruction for decrypting the sensitive information is received; and if the decryption instruction is received, verifying the decryption instruction, and converting the sensitive information into non-hidden display after the verification is passed. Specifically, password-free unlocking or password unlocking can be set, the system detects that the user clicks a keyword area, if no password is set, the original text is directly displayed, and if the password is set, the password unlocking frame is pulled up, or face recognition unlocking, voice control unlocking and the like are performed for unlocking.
