Description

Technical Field

[0001] The present invention relates to the field of terminals, and in particular to a privacy protection method and device for a mobile terminal, and a mobile terminal. Background Art

[0002] With the development of technology and interpersonal communication, mobile terminals have become an important means of communication for people. Mobile terminals are usually private items, but due to interpersonal relationships, difficulty in refusing or politeness, people cannot completely prevent their mobile terminals from being used by others. There are many people's privacy on mobile terminals, such as text messages, contacts, call records, photos, instant messaging messages, etc. People hope that their privacy can be protected when their mobile terminals are used by others. In order to solve the privacy protection problem of mobile terminals, most mobile terminals are set with a privacy protection mode to ensure that in the privacy protection mode, non-owners have difficulty obtaining the privacy on the mobile terminal.

[0003] There are many ways to implement the privacy protection mode in the prior art. One method is to return virtual data when the application on the terminal is opened when the mobile terminal is in the privacy protection mode. For example, in the privacy protection mode, the photo album will be displayed as empty when opened, or only the non-private photos set by the user will be displayed. The disadvantage of this method is that the setting of the returned virtual data is relatively complicated and cumbersome. If there are many applications, the setting is even more complicated. Moreover, if the virtual data is not realistic enough, it is easy to be noticed by other users, causing unnecessary embarrassment.

[0004] Another method is to enter different modes by setting different authentication methods, such as different passwords, patterns, PIN codes, and fingerprints corresponding to privacy modes and normal operating modes. This method is relatively convenient to set up, but the method usually prompts the user to enter a password, draw a pattern, or prompts the user to scan a fingerprint, which makes it easy for the user to detect that a mode has been adopted. For example, a mobile terminal is set to enter different modes with different passwords. Usually, the normal mode is entered by entering the correct password, and the privacy protection mode is entered by entering an incorrect password. At this time, the mobile terminal prompts the user to enter a password, and the user can open the lock screen by entering any incorrect password. The user knows that the entered password is incorrect but the lock screen is still opened, so he realizes that he has entered the privacy protection mode. Another drawback of this method is that the authentication information needs to be entered only when the lock screen is opened, and privacy protection cannot be achieved when the user operates the application after opening the lock screen.

[0005] It can be seen that there is no convenient, fast and user-unnoticed privacy protection method for mobile terminals in the prior art. Summary of the invention

[0145] The above drawings have shown clear embodiments of the present invention, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present invention in any way, but to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0146] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0147] In order to fully understand the present invention, many specific details are mentioned in the following detailed description, but it should be understood by those skilled in the art that the present invention can be implemented without these specific details. In other embodiments, well-known methods, processes, components and circuits are not described in detail to avoid unnecessary ambiguity of the embodiments.

[0148] The embodiments of the present invention provide a mobile terminal privacy protection method, a protection device and a mobile terminal, which can protect the privacy of a user on the mobile terminal and are not easily detected by other users.

[0149] Figure 1 FIG. 1 is a flow chart of a mobile terminal privacy protection method according to an embodiment of the present invention. Figure 1 Said method comprises:

[0150] Step 101, obtaining an application startup instruction.

[0151] The application unit on the mobile terminal can also be called an application program (APP for short), such as photo albums, text messages, call logs, etc. When a user wants to start an application program, he can touch the icon of the application program. After the icon of the application program is touched, an application program start instruction is generated.

[0152] Step 102: Actively obtain the user's biometric features according to the application startup instruction.

[0153] Specifically, the implementation method of actively acquiring biometrics does not require prompting the user, does not require obtaining the user's biometrics with the user's permission, and can also obtain the user's biometrics without obtaining the user's biometric input instruction. The active acquisition method is relatively covert and not easily detected by the user.

[0154] Step 103: If the acquired biometric feature of the user matches the preset biometric feature, the encrypted content list and the non-encrypted content list of the application are displayed.

[0155] The encrypted content list of the application is generated based on the encrypted content in the application, and the unencrypted content list of the application is generated based on the unencrypted content in the application. The encrypted content of the application is the content that is not presented when the acquired user biometrics do not match the preset biometrics. In short, the encrypted content can be the content that the user sets a password for and does not want to be seen by other users.

[0156] The user can set the status of specific content in the application unit, which can include encryption or non-encryption. The encrypted content is the content that the user does not want other users to see, such as photos in the album. The user can set a password for the photos that he does not want other users to see.

[0157] When the acquired user biometric feature does not match the preset biometric feature, the unpresented content includes at least one element, which may be text, a picture, a video, etc. An element is usually presented in the form of an entry. The encrypted content list may be presenting the encrypted content in the form of a list.

[0158] The list in the embodiment of the present invention can be understood in a broad sense. For different applications, the form of the content list can also be different, which can be a bar list or a block list. For example, if it is a text message or instant messaging program, the content list can be a list of sender numbers, such as Figure 2 The bar-shaped SMS list shown, Figure 2The list shown only shows the sender's number or name; if it is an album, the content list can be a list of block thumbnails of photos, such as Figure 3 As shown, Figure 3 301 and 302 are both thumbnails of photos; if it is a recording software or music player software, the content list can be a list of file names.

[0159] The method of the embodiment of the present invention actively obtains the user's biometric features after receiving an application startup instruction. If the matching result between the obtained biometric features and the preset biometric features shows confidential content and non-encrypted content, the leakage of the user's privacy on the mobile terminal can be avoided, and the user's privacy can be protected. The method of actively obtaining biometric features can also make it difficult for the user to detect.

[0160] In one embodiment of the present invention, after step 103, after actively acquiring the user's biometric features, the method further includes:

[0161] If the biometric feature of the user is not obtained, displaying a non-encrypted content list of the application; or

[0162] If the acquired user biometric feature does not match the preset biometric feature, the non-encrypted content list of the application is displayed.

[0163] In one embodiment of the present invention, the actively acquiring the user's biometric features includes:

[0164] Actively obtain the user's facial features; or

[0165] Actively obtain the user's iris features; or

[0166] Actively obtain the user's fingerprint.

[0167] There are two ways to obtain fingerprints: one is to obtain through a dedicated fingerprint acquisition device, and the other is to obtain through the mobile terminal screen. The location of the fingerprint acquisition device of the mobile terminal varies depending on the model of the mobile terminal. The fingerprint acquisition unit of the iPhone is on the home button, and the fingerprint acquisition unit of the Huawei phone is on the back of the phone.

[0168] The screen of some models of mobile phones can be regarded as a screen fingerprint acquisition device, and the user's fingerprint can be directly acquired by the user touching the mobile terminal screen. Acquiring the user's fingerprint by touching the screen is more secretive.

[0169] Active acquisition can prevent other users who are not the owner of the device from noticing that the biometric features are being acquired for subsequent verification, thereby protecting the privacy of the mobile terminal and avoiding possible embarrassment.

[0170] In other embodiments of the present invention, the biometric acquisition unit may also be an audio acquisition unit to acquire the user's voice.

[0171] In other embodiments of the present invention, after displaying the non-encrypted content list of the application, the method further includes:

[0172] Actively acquiring, via the touch screen of the mobile terminal, a fingerprint input by a user when manipulating the non-encrypted content list;

[0173] If the actively acquired fingerprint matches a preset biometric feature, a list of encrypted and non-encrypted contents of the application is displayed.

[0174] If the owner does not face the camera directly when launching the application, or there is a problem with light or distance, the facial features or iris features captured by the camera may be unclear or deformed, or the fingerprint may not be clear when actively acquiring it, and it may be difficult to match successfully later, making it difficult for the owner to obtain all the information they want. In the embodiment of the present invention, after the non-encrypted content list is displayed due to the above problems, the user's fingerprint is actively acquired by touching the mobile terminal screen when the user selects an item on the non-encrypted content list, which can avoid the inconvenience caused to the owner by misjudgment.
