Detailed Description
The following detailed description will be provided with reference to the accompanying drawings and embodiments, so that how to apply the technical means to solve the technical problems and achieve the corresponding technical effects can be fully understood and implemented. The embodiments and various features in the embodiments of the present application can be combined with each other without conflict, and the formed technical solutions are all within the scope of protection of the present application.
Example one
Referring to fig. 1, the present application provides a touch screen state control method of a terminal device, where the touch screen state control method includes steps S110 to S140.
Step S110: when the terminal equipment is in an unlocking state and the finger of a user is detected to touch the touch screen of the terminal equipment, the biological characteristic information of the user is obtained.
It can be understood that, in consideration of the fact that a user may not lock the terminal device and the terminal device is not on the hand of the user during the process of using the terminal device, in this case, in order to prevent other users (i.e., users who do not have the right to use the terminal device) from operating the terminal device with the gap, the terminal device in the unlocked state needs to be securely authenticated to avoid the problems of stealing photos or files stored in the terminal device, and the like.
In addition, considering that when a user touches the touch screen of the terminal device, it indicates that the user wants to perform an operation on the terminal device, in order to ensure the security of the terminal device in the unlocked state, in this embodiment, when the terminal device is in the unlocked state and it is detected that a finger of the user touches the touch screen of the terminal device, the security verification for the terminal device is triggered, that is, the biometric information of the user is obtained for security verification. It should be noted that the terminal device is an electronic device with a touch screen, including but not limited to: terminal equipment such as cell-phone, computer and panel computer.
It can be further understood that, since the biometric information of different users has uniqueness, whether the user is a user with the use right of the terminal device is determined by performing security verification on the acquired biometric information of the user.
The biometric information of the user may be fingerprint information, face information, or voiceprint information. It should be noted that, in practical applications, the biometric information may also be any other biometric information meeting practical use requirements, and the embodiment of the present application is not limited at all.
For example, the biometric information of the user is taken as face feature information for explanation. The specific way for the terminal device to obtain the biometric information of the user may be: the terminal equipment shoots a picture through a front camera on the terminal equipment. If the user is located in the shooting range of the front camera, the terminal equipment can shoot a photo through the front camera, detect a portrait of the user from the shot photo and separate the portrait of the user from a background; then, the terminal device may acquire facial feature information of the user (i.e., biometric information of the user) from the separated portrait according to a facial recognition algorithm.
For example, the biometric information of the user is taken as fingerprint feature information for explanation. The specific way for the terminal device to obtain the biometric information of the user may be: the terminal equipment acquires the fingerprint of the finger contacting with the touch screen through the touch screen of the terminal equipment and extracts the fingerprint characteristic information in the fingerprint.
For example, the biometric information of the user is taken as voiceprint feature information for explanation. The specific way for the terminal device to obtain the biometric information of the user may be: when the terminal equipment is in an unlocking state and the condition that the finger of a user touches the touch screen of the terminal equipment is detected, the terminal equipment starts a recording function, collects the sound of the user and provides voiceprint characteristic information in the sound. It can be understood that if the terminal device verifies by acquiring the voiceprint feature information, the prompt information can be displayed when the security verification aiming at the terminal device is triggered, so as to prompt the user to sound to complete the acquisition of the voiceprint feature information.
Step S120: and judging whether the biological characteristic information is matched with preset biological characteristic information.
In this embodiment, the preset biometric information is the biometric information pre-stored by the user having the terminal device usage right, and is used for comparing the biometric information with the biometric information acquired when the terminal device is in an unlocked state and it is detected that the finger of the user touches the touch screen of the terminal device, and the terminal device determines whether the user has the terminal device usage right according to the comparison result. It is understood that the preset biometric information may also be fingerprint information, face information, or voiceprint information, etc. corresponding to the acquired biometric information. It should be noted that, in practical applications, the preset biometric information may also be any other biometric information meeting practical use requirements, and the embodiment of the present application is not limited at all.
It is understood that, in this embodiment, the fact that the biometric information matches the preset biometric information means that the biometric information of the user is the same as the preset biometric information. Or, the matching of the biometric information and the preset biometric information means that the similarity between the biometric information of the user and the preset biometric information is greater than or equal to a preset threshold. For example, the preset threshold may be 98%, that is, if the similarity between the biometric information of the user and the preset biometric information is greater than or equal to 98%, the biometric information of the user matches with the preset biometric information.
Correspondingly, the fact that the biometric information is not matched with the preset biometric information means that the biometric information of the user is different from the preset biometric information. Or, the matching of the biometric information and the preset biometric information means that the similarity between the biometric information of the user and the preset biometric information is smaller than a preset threshold. For example, the preset threshold may be 98%, that is, if the similarity between the biometric information of the user and the preset biometric information is less than 98%, the biometric information of the user does not match with the preset biometric information.
For example, the obtained biometric information of the user is taken as face feature information for explanation, and correspondingly, the preset biometric information is preset face feature information. Judging whether the biological characteristic information is matched with preset biological characteristic information specifically comprises the following steps: firstly, preset face feature information stored in the terminal equipment is obtained, and whether the face feature information is the same as the preset face feature information or not is judged according to the obtained preset face feature information and the face feature information. And if the face feature information is the same as the preset face feature information, determining that the face feature information is matched with the preset face feature information.
For example, the obtained biometric information of the user is taken as fingerprint feature information for explanation, and correspondingly, the preset biometric information is preset fingerprint feature information. Judging whether the biological characteristic information is matched with preset biological characteristic information specifically comprises the following steps: firstly, acquiring preset fingerprint characteristic information stored in the terminal equipment, and judging whether the similarity between the fingerprint characteristic information and the preset fingerprint characteristic information is greater than or equal to 98% or not according to the acquired preset fingerprint characteristic information and the acquired fingerprint characteristic information. And if the face characteristic information and the preset face characteristic information are greater than or equal to 98%, determining that the fingerprint characteristic information is matched with the preset fingerprint characteristic information.
Illustratively, the obtained biometric information of the user is taken as voiceprint feature information, and correspondingly, the preset biometric information is preset voiceprint feature information. Judging whether the biological characteristic information is matched with preset biological characteristic information specifically comprises the following steps: firstly, acquiring preset voiceprint characteristic information stored in the terminal device, and judging whether the similarity between the voiceprint characteristic information and the preset voiceprint characteristic information is greater than or equal to 95% or not according to the acquired preset voiceprint characteristic information and voiceprint characteristic information. And if the voiceprint characteristic information and the preset voiceprint characteristic information are greater than or equal to 95%, determining that the voiceprint characteristic information is matched with the preset voiceprint characteristic information.
When the biometric information does not match the preset biometric information, the terminal device performs step S130: and controlling the terminal equipment to be switched from an unlocking state to a screen locking state so as to protect the terminal equipment.
In this embodiment, when the biometric information of the user does not match the preset biometric information, it indicates that the biometric information of the user fails to be verified, and the user does not have the usage right of the terminal device. After the verification fails, the terminal device is switched from the unlocking state to the screen locking state, so that a user who does not have the use permission of the terminal device is prevented from using the terminal device, and the safety of the terminal device in the unlocking state is improved. And if the terminal equipment needs to be used, unlocking the terminal equipment.
When the biometric information matches the preset biometric information, performing step S140: and maintaining the unlocking state of the terminal equipment, receiving touch operation on the position where the user touches the touch screen of the terminal equipment, and responding to the touch operation on the position.
In this embodiment, when the biometric information of the user matches the preset biometric information, it indicates that the biometric information of the user is successfully verified, and the user has the usage right of the terminal device. And after the verification is successful, the terminal equipment keeps an unlocking state, receives touch operation on the position where the user touches the touch screen of the terminal equipment, and responds to the touch operation on the position.
For example, the obtained biometric information of the user is taken as face feature information for explanation, and correspondingly, the preset biometric information is preset face feature information. After the face feature information is confirmed to be matched with the preset face feature information, when the terminal device receives that the touch operation of the user touching the touch screen of the terminal device is to open a microblog, the terminal responds to the touch operation of opening the microblog so as to meet the requirements of the user.
It can be understood that, in order to reduce the power consumption of the terminal device, after the first verification is successful and the finger of the user does not leave the touch screen of the terminal device, if there is another finger touching the touch screen of the terminal device, the biometric information of the user does not need to be acquired, but the touch operation at the position where the other finger touches the touch screen of the terminal device is directly received, and the touch operation at the position is responded.
Referring to fig. 2, the present embodiment further provides a method for controlling a touch screen state of a terminal device, and after the step S140 is executed, the method for controlling a touch screen state further includes steps S210 to S213.
Step S210: and acquiring pressure data detected by a pressure sensor in the terminal equipment.
In this embodiment, when the finger of the user does not leave the touch screen of the terminal device, the pressure data detected by the pressure sensor in the terminal device will not be zero. Therefore, after obtaining the pressure data, step S211 is executed: and judging whether the pressure data is zero or not so as to determine whether the finger of the user leaves the touch screen of the terminal equipment or not.
When the pressure data is not zero, that is, it is determined that the finger of the user does not leave the touch screen of the terminal device, executing step S213: when the situation that the fingers of the user do not leave the touch screen of the terminal equipment and other fingers touch the touch screen of the terminal equipment is detected, receiving touch operation on the position where the other fingers touch the touch screen of the terminal equipment, and responding to the touch operation on the position; when the pressure data is zero, that is, it is determined that the finger of the user leaves the touch screen of the terminal device, the step S110 is returned to: and when the terminal equipment is in an unlocking state and the finger of the user is detected to touch the touch screen of the terminal equipment, acquiring the biological characteristic information of the user, and verifying whether the biological characteristic information is matched with the preset biological characteristic information again.
In this embodiment, when a second finger touches the touch screen of the terminal device, detecting whether the verified first finger leaves the touch screen of the terminal device, and if the first finger does not leave the touch screen of the terminal device, that is, it is determined that the terminal device does not leave the hand of the user having the terminal device usage right, directly receiving a touch operation at a position where the second finger touches the touch screen of the terminal device, and responding to the touch operation at the position, thereby reducing unnecessary verification steps executed by the terminal device, and reducing power consumption of the terminal device; after the first finger which passes the verification is detected to leave the screen of the terminal device, when the terminal device is in an unlocking state and the finger of the user is detected to touch the touch screen of the terminal device, the biological characteristic information of the user is obtained again, whether the biological characteristic information is matched with the preset biological characteristic information or not is judged, whether the user is a user with the use permission of the terminal device or not is determined, and the safety of the terminal device in the unlocking state is improved.
