detailed description

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

The terminal equipment security control method, device and terminal equipment according to the embodiments of the present invention are described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a terminal device security control method provided according to an embodiment of the present invention. As shown in Fig. 1, the method includes:

Step 101, when the terminal device is successfully unlocked, control the terminal device from a locked state to an unlocked state.

Specifically, in order to ensure the security of use, it is necessary to unlock the terminal device by means of pattern or password unlocking before unlocking the terminal device. When the user inputs a correct pattern or password, the terminal device can be unlocked. Of course, those skilled in the art can also think of other unlocking methods, such as fingerprint, face or iris based unlocking methods based on biometric features. In this embodiment, no limitation is imposed on the unlocking manner of the terminal device.

When the terminal device is successfully unlocked, the terminal device displays the desktop, thereby entering the unlocked state from the locked state. In the unlocked state, the user is allowed to operate the terminal device. Specifically, the user may click an icon on the desktop to run an application program corresponding to the icon. Or, perform operations such as making a phone call and viewing push messages.

Step 102, in the unlocked state, collect the biological characteristics of the user.

Specifically, in the unlocked state, when the use state of the terminal device satisfies the preset security control condition, biometric feature collection starts. If the biometric feature is not collected, the prompt information of biometric feature collection is displayed, and at least one biometric feature is re-collected. When the number of times of re-collection satisfies the preset number of times, the terminal device is controlled to enter a locked state.

As a possible implementation manner, the preset security control condition includes a preset time period since the last collected biometric feature. That is to say, the biological characteristics of the user are collected periodically. For example, when a user is using a terminal device, the terminal device periodically obtains the user's facial features through a front-facing camera to perform facial recognition.

As another possible implementation manner, the preset security control condition includes detecting that the target application program is running. The target application here may be a security-sensitive application, for example, it may include a bank client, a third-party payment application, and the like.

As yet another possible implementation manner, the preset safety control condition includes capturing the detection object within the detection range. Wherein, the detection objects mentioned here at least include iris, human face and/or fingerprint.

Step 103, perform identity verification according to biometric features.

Optionally, query the user identity used when the terminal device is successfully unlocked; match each of the at least one biometric feature collected according to the standard template library of the user identity; the biometric features include Iris features, face features and/or fingerprint features; if there is at least one biometric feature that does not match the template of the biometric feature in the standard template library, it is determined that the identity verification has failed.

Wherein, in the standard template library, templates corresponding to different biometric features of the same user identity are stored. The templates of each biometric feature stored in the standard template library need to be pre-set by the user as a corresponding user.

It should be noted that there may be multiple templates for the same biometric feature under the same user identity, instead of being limited to one template. For example: user A corresponds to user identity A in the terminal device mentioned in this embodiment, multiple fingerprint templates can be stored in the standard template library of user identity A, and different fingerprint templates correspond to different fingers.

Step 104, if the identity verification passes, the control terminal device continues to be in an unlocked state.

As a possible implementation, if in step 103, the user identity used when the terminal device is successfully unlocked is inquired; according to the standard template library of the user identity, the collected at least one biometric feature Each type is matched, so that it is determined that the identity verification is passed, indicating that the terminal device is currently being used by the user who initially unlocked the terminal device. In this case, the security is relatively high, and the terminal device can be controlled to continue to be in an unlocked state.

Step 105, if the identity verification fails, control the terminal device to enter a locked state.

If in step 103, the user identity used when the terminal device is successfully unlocked is checked; according to the standard template library of the user identity, each of the collected at least one biometric feature is matched to determine If the authentication fails, it means that the terminal device is not currently being used by the user who initially unlocked the terminal device. In this case, there are certain potential safety hazards, and it is necessary to control the terminal device to enter the locked state.

In the embodiment of the present invention, when the terminal device is successfully unlocked, after the terminal device is controlled to enter the unlocked state from the locked state, the user's biological characteristics are collected in the unlocked state. Further, identity verification is performed according to the biometric feature. If the identity verification is passed, the terminal device is controlled to remain in the unlocked state, and if the identity verification is not passed, the terminal device is controlled to enter the locked state. During the use of the terminal device, identity verification is performed again, so as to enhance security, and at the same time, due to the use of biometrics for identity verification, the identity verification process is prevented from interfering with the user's use process.

On the basis of the previous embodiment, in order to clearly illustrate the foregoing embodiment, FIG. 2 is a flow chart of another terminal device security control method provided according to an embodiment of the present invention. As shown in FIG. 2 , the method includes:

Step 201, when the terminal device is successfully unlocked, control the terminal device from the locked state to the unlocked state.

Specifically, for the implementation of this step, reference may be made to the relevant description of step 101 in the foregoing embodiments, and details will not be repeated in this embodiment.

Step 202, inquire about the user identity used when the terminal device is successfully unlocked, and turn on the relevant device for biometric feature collection.

Optionally, the terminal device may be registered with multiple user identities at the same time, and different user identities may have different usage rights. Specifically, an end device may have user identities including administrator and/or guest. In order to facilitate management, biometric features are pre-collected for users with different user identities, and a standard template library corresponding to user identities is formed.

In the standard template library corresponding to the same user identity, it may be obtained by pre-collecting multiple biometric features of the user of the user identity. Therefore, the standard template library corresponding to the user identity includes templates corresponding to multiple biometric features.

For example: the fingerprint feature and face feature of the visitor are collected, and the standard template library corresponding to the visitor includes the template of the fingerprint feature of the visitor and the template of the face feature of the visitor.

Step 203, start to collect biometrics.

Optionally, start to collect biometrics periodically, or start to collect corresponding biometrics when the detection object enters the detection range. The detection objects here include irises, faces and/or fingerprints. Correspondingly, biological features include iris features, face features and/or fingerprint features.

In step 204, it is judged whether biometric features are collected, if yes, execute step 206, otherwise execute step 205.

Step 205 , displaying the prompt information of biometric feature collection, and judging whether the number of repeated biometric feature collection is greater than the preset number of times, if so, go to step 206 , otherwise, go back to step 203 .

Specifically, if the biometric feature is not collected this time, a prompt message that the biometric feature collection is unsuccessful this time is displayed, so as to remind the user who is currently using the terminal device to cooperate to complete the subsequent biometric feature collection. If the number of repeated collections of biometrics is greater than the preset number of times after repeated collections, but the required biometrics are still not collected, it can be determined that there is a high security risk.

Step 206, controlling the terminal device to enter the locked state.

In a possible application scenario, if the number of repeated collections of biometrics is greater than the preset number of times after repeated collections, but the required biometrics are still not collected, it can be determined that there is a high level of security. risk.

In another possible application scenario, although the biometrics have been collected, at least one biometric does not match the template of the biometric in the standard template library, and it is determined that the identity verification fails. In this case, it can be determined that there is a high security risk.

Furthermore, in order to control this security risk, it is necessary to control the terminal device into a locked state, so as to avoid allowing the user to continue to operate the terminal device and stop further losses caused by its use.

Step 207, matching each of the at least one biometric feature collected according to the standard template library of the user identity.

Specifically, in the standard template library corresponding to the same user identity, it may be obtained by pre-collecting multiple biometric features of the user of the user identity. Therefore, the standard template library corresponding to the user identity includes templates corresponding to multiple biometric features.

Correspondingly, when matching, in the standard template library of the user identity, the templates of each biological feature can be matched with the corresponding collected biological features to determine whether the collected biological features match the templates in the standard template library. match. Only when it is determined that the collected biometric features match the templates in the standard template library, can it be determined that the user who is currently using the terminal device has the user identity corresponding to the standard template library.

Step 208, according to the matching result, judge whether the identity verification is passed, if passed, execute step 209, otherwise, execute step 206.

Optionally, if at least one biological feature does not match the template of the biological feature in the standard template library, it is determined that the identity verification fails. If each of the collected biometric features matches the template of the corresponding biometric feature in the standard template library, it is determined that the identity verification is passed.

Step 209, controlling the terminal device to continue to be in an unlocked state.

In the case where it is determined that the user who is currently using the terminal device has the user identity corresponding to the standard template library, the security risk is low, so security prevention and control is not required. Allows the end device to remain unlocked.

In the embodiment of the present invention, when the terminal device is successfully unlocked, after the terminal device is controlled to enter the unlocked state from the locked state, the user's biological characteristics are collected in the unlocked state. Further, identity verification is performed according to the biometric feature. If the identity verification is passed, the terminal device is controlled to remain in the unlocked state, and if the identity verification is not passed, the terminal device is controlled to enter the locked state. During the use of the terminal device, identity verification is performed again, so as to enhance security, and at the same time, due to the use of biometrics for identity verification, the identity verification process is prevented from interfering with the user's use process.
