[0072] By providing a method and a device for privacy protection, the embodiments of the present invention solve the technical problem that user privacy data is likely to be leaked when an electronic device is borrowed in the prior art, and achieve the technical effect that privacy data will not be leaked when the electronic device is borrowed, thus ensuring data security.

[0073] The technical solution of the embodiments of the present invention for solving the above technical problem is generally as follows:

[0074] A method for privacy protection, which is applied to an input method client, and the method includes: when it is detected that a user operates on an electronic device, collecting biometric data of the user; matching the biometric data of the user with preset biometric data in the electronic device; if the matching fails, encrypting the privacy data in the electronic device.

[0075] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0076] First, it should be noted that the term "and / or" appearing in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this article, the character " / " generally represents an "or" relationship between the associated objects before and after.

[0077] Embodiment 1

[0078] This embodiment provides a method for privacy protection, which is applied to an electronic device. The electronic device can be an electronic device with a display screen, such as: a smart phone, a tablet computer, a PC (Personal Computer), an Internet TV, etc. The user can use this electronic device to edit and view information. Here, for what specific device the electronic device is, this embodiment does not make a specific limitation. And, an input method client is installed in this electronic device to provide convenient text input. It should be noted here: For the method in this embodiment, its corresponding program code is integrated in the input method client. That is to say, the execution subject of this method is the input method client.

[0079] Specifically, as Figure 1 shown, the method for privacy protection includes:

[0080] Step S101: When it is detected that the user operates the electronic device, collect the user's biometric data.

[0081] In the specific implementation process, the user's operation on the electronic device can be: the user touches the touch screen of the electronic device, or the user clicks a certain button or any button on the electronic device, or the user uses any hardware or software on the electronic device, or the user uses the specified hardware or software on the electronic device, etc.

[0082] In the specific implementation process, when it is detected that the user operates the electronic device, it means that the electronic device has entered the used state. At this time, there are two situations: First, it is used by the owner of the electronic device; Second, it is used by others. Therefore, at this time, the input method client can generate an activation command to activate the relevant hardware device on the electronic device for biometric data collection.

[0083] In the specific implementation process, a hardware device (or a software program, firmware, etc. that is simultaneously matched and controlled) for collecting biometric data can be set on the electronic device. The hardware device can be: a camera, a fingerprint module (such as an in-screen fingerprint), a pulse sensor, etc.

[0084] In the specific implementation process, the biometric data includes one or more of the following data:

[0085] Facial data, which can be static pictures or dynamic short videos. For example, facial information including blinking eyes or opening the mouth can be collected through a camera.

[0086] Fingerprint data, which can be a user's finger fingerprint or palm print and can be collected through a fingerprint module.

[0087] Iris data, which can be collected through a camera.

[0088] Pulse data or heart rate data, which can be collected through a pulse sensor.

[0089] In addition, the biometric data can also be data representing a user's usage habits, such as using an electronic device with the left hand or the right hand. When collecting data on the user's usage habits, it can be input based on one or more hardware devices, such as a camera, a pressure sensor, and a touch screen (judgment is based on the touch range and frequency on the screen).

[0090] In the specific implementation process, when collecting a user's biometric data, one biometric data can be collected, or multiple biometric data can be collected for comprehensive judgment to improve the recognition accuracy.

[0091] In the specific implementation process, when collecting a user's biometric data, it can be collected in real time by the input method client, or intermittently. Preferably, the intermittent collection method is adopted, which can reduce the power consumption of the electronic device. At the same time, it can timely monitor the changes of the user (for example, the situation where a non-owner uses the mobile phone), so as to encrypt the privacy data in time and avoid the leakage of privacy data.

[0092] Step S102: Match the user's biometric data with the preset biometric data in the electronic device.

[0093] In the specific implementation process, the preset biometric data is the biometric data of the owner of the electronic device, which is stored in the memory of the electronic device (such as read-only memory or flash memory). After the electronic device collects biometric data, the input method client can (directly or indirectly) call the pre-stored preset biometric data for matching.

[0094] In the specific implementation process, the process of biometric data matching can be similarity matching. To ensure the matching efficiency, a threshold can be set for the matching result. For example, the threshold is 95%. If the similarity of the matching result exceeds 95%, it can be determined as a successful match; otherwise, it is determined as a failed match, and the next step is performed.

[0095] Step S103: If the matching fails, encrypt the privacy data in the electronic device.

[0096] In a specific implementation process, if the matching fails (i.e., the collected biometric data fails to match the preset biometric data), it indicates that the user of the electronic device has changed and is no longer the owner. In this case, the input method client can encrypt the privacy data in the electronic device to prevent privacy leakage.

[0097] In a specific implementation process, the privacy data of the user may include one or more of the following data:

[0098] (1) Historical data input by the input method client, such as: input text information, expression information in the input emoticons, input picture information, etc.;

[0099] (2) Content input in the current chat interface, such as: conversation information input in the QQ chat box (when encrypting by the input method client, the received chat information can also be encrypted together), conversation information in the WeChat chat box, comment and communication information in the forum and space;

[0100] (3) Picture files, which can come from the input of the input method client, the shooting by the camera of the electronic device itself, downloading from the Internet, and receiving through chat;

[0101] (4) Video files, such as shooting by the camera, downloading from the Internet, and receiving through chat software;

[0102] (5) Audio files, such as music, recordings, etc.;

[0103] (6) Documents in a preset format, such as text documents (txt), word documents, spreadsheets, slides, etc.

[0104] (7) Application programs, such as: address book, camera, app store, QQ, WeChat, notepad, recorder, etc. This application program can be customized by the user (i.e., the owner).

[0105] As Figure 2 shown, ([ Figure 2 shows the electronic device 10 and the display screen 11 on the electronic device 10), in order to ensure the flexible use of the present invention and improve the personalization degree. The privacy data can be freely selected (marked) by the user of the electronic device (such as: the owner). For example, if the user only marks the historical data input by the input method client as privacy data, then when the biometric data matching fails, the input method client only encrypts the historical data it has input. Taking the historical data input by the input method client as privacy data, the present invention provides the following specific implementation manner:

[0106] The input method client intelligently identifies numbers, letters, sensitive words, etc., and treats the identified numbers and sensitive words as private data, and encrypts them when the biometric data fails to match. For example, the input method client can identify an 18-digit number or a 17-digit number plus a letter as an ID card number, and use it as private data; or, the input method client can identify a 6-digit number or a combination of 7-12 digits, letters and symbols as a password, and use it as private data; or, the input method client can use sentences containing sensitive words as private data, such as sensitive words such as: "account", "password", "mobile phone number", "wife", etc. Sensitive words can also be set by the user (i.e.: the owner of the device).

[0107] The historical data input by the input method client can be cached and marked locally, and the content (or key identification parts) can also be backed up to the cloud to ensure that the data that needs to be encrypted can be accurately located when encrypting private content.

[0108] During the specific implementation process, when encrypting the content input in the current chat interface, the input method client can perform feature recognition on the currently displayed page to determine whether there is a chat box in the current page and the area where the chat box is located. After the determination is completed, all text, emoticons, pictures and other contents in the chat box can be encrypted.

[0109] In the specific implementation process, the form of encryption is not limited, such as hiding, garbled display, partial display, etc.

[0110] In the specific implementation process, the encryption method is not limited, and a reversible encryption algorithm can be used, such as RSA asymmetric encryption algorithm, DES (Data Encryption Standard, DES), 3DES (Triple DES, triple encryption algorithm), AES (Advanced Encryption Standard, AES), SM4 (SMS4.0 block cipher algorithm), etc. In addition, manually customized simple reversible encryption rules can also be used.

[0111] During the specific implementation process, when performing encryption, the input method client can directly encrypt the user's private data; or the input method client can generate an encryption control instruction to call and start encryption software that matches (associated with or supporting) the input method client to encrypt the user's private data.

[0112] In this embodiment, a usage scenario is also provided: when someone else uses the electronic device without the knowledge of the owner of the electronic device, and at this time when the biometric data matching fails, the input method client can locally save the collected biometric data or transmit it to the cloud for storage. After the biometric data matches successfully the next time, the input method client generates a privacy prompt message, and displays or enters through the privacy prompt message to display the biometric data (such as: face data) collected last time (or historically collected), so as to inform the host of the electronic device who has viewed the electronic device.

[0113] Here, in order to ensure the validity of the saved biometric data and exclude the situation where someone accidentally touches the electronic device, the following biometric data storage method is provided in this embodiment:

[0114] Set a time threshold for saving biometric data. This time threshold can be custom-set. After the currently collected biometric data fails to match the preset biometric data, the currently collected biometric data is temporarily saved (logically saved). After the interval time exceeds the above time threshold (for example: within 5 to 10 seconds), biometric data is collected again. If the biometric data collected twice is the same (that is: the match is successful), it is determined that the user corresponding to the temporarily saved biometric data is indeed viewing the content in the electronic device (not accidentally touching the electronic device). At this time, the temporarily saved biometric data is physically saved, thus ensuring the validity of the saved biometric data.

[0115] There is the following scenario in this embodiment that applies to this privacy protection method:

[0116] For the usage scenario of borrowing an electronic device, an entry for setting can be provided in the input method to which the method provided by the present invention is applied, for setting the access time of a specified application. Set the access time, number of times, etc. after the collected biometric data fails to match the preset biometric data. For example, when the electronic device is borrowed and the collected biometric data fails to match, the usage time of the browser of the electronic device is 30 minutes, and after 30 minutes, it will be hidden in the background by the input method and encrypted. Another example is that when the electronic device is borrowed and the collected biometric data fails to match, the access times of the notepad installed on the electronic device are 2 or 3 times. After the access times exceed the set number of times, it will be hidden in the background by the input method and encrypted. Thus, the multi-scenario applicability of the electronic device can be improved while ensuring the security of privacy data.

[0117] In this embodiment, when the biometric data matches the preset biometric data successfully, the input method client can decrypt the encrypted privacy data in the electronic device. That is to say, after determining that the current user is the device owner, the encrypted privacy data is decrypted.

[0118] As an alternative embodiment, before step S101, it further includes: inputting the preset biometric data.

[0119] Specifically, as Figure 3 shown, the inputting of the preset biometric data includes:

[0120] Step S301: Generate guiding information for guiding the user to input the preset biometric data.

[0121] In the specific implementation process, as Figure 4 shown, the guiding information can pop up automatically when the user (such as the device owner) uses the input method client, or the user can actively enter the settings interface of the input method client and operate to enter. The guiding information can include: text for guiding the user's operation, options for the user to select (the options can include the categories of inputting the preset biometric data, such as face data, fingerprint data, iris data, etc.), and the user can select one or more biometric data for matching, as Figure 5 shown.

[0122] Step S302: Pre-collect biometric data according to the guiding information.

[0123] In the specific implementation process, the collection method of the biometric data is the same as that in step S101, which will not be elaborated here.

[0124] Step S303: Store the pre-collected biometric data as the preset biometric data.

[0125] In the specific implementation process, the stored preset biometric data is used for the matching comparison in step S102.

[0126] As an alternative embodiment, the electronic device in this embodiment can be used by multiple users at the same time. These users are all legal users of the electronic device. The preset biometric data of each legal user can be stored in the electronic device, and the privacy data of each legal user is also stored. The input method client can encrypt and decrypt these privacy data separately, and the privacy data of each legal user can be protected.

[0127] For example, an electronic device is used by user A and user B at the same time. The preset biometric data A of user A and the preset biometric data B of user B are stored in the electronic device. At the same time, the private data A of user A and the private data B of user B are also stored. By default, both the private data A and the private data B are in an encrypted state. When performing step S101-step S102, if it is found that the biometric data of the current user matches the biometric data A, it means that user A is using the electronic device, and then the private data A is decrypted; after a preset period (for example: after 30 seconds or 1 minute), the electronic device performs step S101-step S102 again. If it is found that the biometric data of the current user cannot match the preset biometric data A, but can match the biometric data B, it indicates that user A has left and now user B is using the electronic device. Then, the private data B can be decrypted, and at the same time, the private data A is encrypted.

[0128] The technical solutions in the above embodiments of the present invention at least have the following technical effects or advantages:

[0129] In an embodiment of the present invention, a method for privacy protection is disclosed, including: when it is detected that a user operates an electronic device, collecting the biometric data of the user; then matching the biometric data of the user with the preset biometric data in the electronic device. If the matching fails, it means that the user currently using the electronic device is not the owner of the electronic device. At this time, the private data in the electronic device is encrypted to achieve the purpose of protecting privacy. Therefore, the technical problem that the user's private data is easily leaked when the user terminal in the prior art is borrowed is solved, and the technical effect that the private data will not be leaked when the user terminal is borrowed is realized, ensuring data security.
