Based on the above mobile terminal hardware structure and the communication network system, various embodiments of the method of the present invention are provided.
As shown in fig. 3, in one embodiment of the present invention, a fingerprint-based operation control method is provided, which is applied to a mobile terminal having a flexible screen, and the method of the present embodiment includes:
step S310, collecting the characteristics of the touch operation of the user on the flexible screen.
In this embodiment, the flexible screen may be deformed under the touch operation of the user, and with the development of the flexible screen technology, more mobile terminals such as mobile phones and tablet computers adopt the flexible screen. In the present embodiment, the feature of the touch operation performed by the user is not limited, and any feature of the touch operation and any information related to the touch operation may be used as the feature of the touch operation.
Step S320, determining whether the characteristics of the touch operation meet the preset conditions.
In the present embodiment, the type of the preset condition is not limited, and may be any condition related to the acquired touch feature.
In the present embodiment, the following examples are provided for acquiring the characteristics of the touch operation, and the following description is made for any judgment as to whether the characteristics of the touch operation meet the preset conditions.
(1) And collecting the pressure of the flexible screen corresponding to the touch operation.
In this embodiment, the pressure of the touch operation is the strength of the fingerprint identification area pressed by the user each time, and because the flexible screen has the characteristic of pressing compression, the user can easily perceive and memorize the corresponding pressing strength, so that the touch pressure of the user can be used as a feature of the touch operation. The mobile terminal is provided with a pressure sensor for collecting the pressure of the touch operation of the user, and specifically, the pressure sensor can be located in a flexible screen, namely, the flexible screen is a pressure screen.
The judgment of the pressure based on the touch operation can be divided into the following two ways:
simple mode: and judging that the pressing force of the user is in accordance with the condition when the pressing force of the user is smaller than or larger than a proper threshold set by the user (for example, the user sets a certain pressing threshold, and the pressing force larger than the threshold is used for encryption initialization), and judging that the pressing force is in accordance with the condition as long as the pressing force of the subsequent user is larger than the pressing force of the user, and judging whether the subsequent fingerprint based on the acquired fingerprint triggers a specific operation or not).
Complex mode: in the mode, whether the pressing force meets the condition is judged, and the two standards of pressing light or heavy are not simply pressed any more, but the force size ranges are strictly distinguished, if the user sets three ranges of small, medium and large, the set thresholds are respectively: small-medium=10, medium-large=20, and when judging whether the pressing force meets the condition, it is necessary to judge whether the force falls in three check intervals—small: [0, 10], wherein: [8,22], dai [18,10000]. It should be noted that, the check interval is not set strictly according to the threshold value set by the user, and this is because the user may not be completely accurate in sensing the strength of the user, so when the strength of the user is checked, a certain error may be allowed in the strength of the user, for example, when the strength of the user is set to be 20 as the threshold value of the strength encryption size interval, the actually set interval is [18,10000], when the strength of the user is pressed by >18, that is, the pressure is determined to be in the large interval, and when the user sets to be 20 as the threshold value of the encryption interval, the actually set interval is [8,22], and when the pressing strength is 22, that is, the pressure is determined to be in the middle interval.
(2) The touch times when the user performs the touch operation are obtained.
In this embodiment, the pressing number verification may be implemented: when triggering a specific operation based on a fingerprint, the user needs to press for a certain number of times, the number of times can be set by the user, the number of times n > =1, and n=1 is that the user only needs to perform one pressing operation, and the user can trigger the specific operation under the conditions that the user presses the flexible screen once and the fingerprint is correct in verification. When n > =2, the number of times the user presses the flexible screen is recorded every time the user presses the flexible screen, and when the user completes n presses and the fingerprint verification is correct, the specific operation can be triggered. If the user sets n=2, the user lightly presses the finger with the thumb of the right hand for the first time, presses the finger with the index finger of the right hand for the second time, and after the user pressing times reach 2 times, the fingerprint pressed by the index finger of the right hand for the second time is collected.
(3) The magnitude of deformation of the flexible screen caused by touch operation is acquired.
In this embodiment, since the flexible screen is used on the mobile terminal, the flexible screen is deformed under the touch operation of the user, that is, the flexible screen is recessed toward the inner direction of the mobile terminal, as shown in fig. 4. Therefore, the deformation amplitude of the flexible screen can be detected through the preset detection, and when the actual change amplitude of the flexible screen exceeds a certain amplitude or is smaller than a certain amplitude, the condition is judged to be met, and the subsequent fingerprint acquisition operation can be performed. According to the technical scheme, the characteristics of the flexible screen are fully utilized, the verification of touch operation of a user is realized, and the safety of operation control based on fingerprints is improved.
In the present embodiment, the above three ways of acquiring a touch operation may also be used in combination.
And step S330, when the judgment result is yes, collecting fingerprints when the user executes touch operation.
In this embodiment, the flexible screen is provided with a sensor for collecting fingerprints, so that fingerprints of the user touching at present can be collected.
Step S340, judging whether to execute the preset operation according to the fingerprint.
In the present embodiment, the type of the preset operation is not limited, and for example, unlocking, payment, opening of the private data, and the like may be performed based on the fingerprint.
According to the technical scheme of the embodiment, when a user performs touch operation on the flexible screen, whether to perform preset operation is not directly judged based on the fingerprint after the fingerprint of the user is acquired, but the characteristics of the touch operation of the user are firstly acquired, and judgment is performed once in advance based on the characteristics of the touch operation of the user to judge whether operation control based on the fingerprint is necessary or not.
As shown in fig. 5, in one embodiment of the present invention, a fingerprint-based operation control method is provided, which is applied to a mobile terminal having a flexible screen, and the method of the present embodiment includes:
Step S510, collecting the characteristics of the touch operation of the user on the flexible screen.
Step S520, determining whether the characteristics of the touch operation meet the preset conditions.
In step S530, when the determination result is yes, in the case that the touch operation causes the flexible screen to form a depression, a fingerprint in a depression shape is acquired.
The fingerprints collected in the prior art solutions are planar fingerprints, whereas the fingerprints collected in the technical solutions of the present embodiment are not planar fingerprints, but rather "stereoscopic" fingerprints. In this embodiment, since the flexible screen of the mobile terminal is deformed under the pressure of the touch operation of the user, that is, the recess is generated, and the fingerprint is in contact with the recess of the flexible screen when the finger of the user touches the flexible screen, whether the fingerprint sensed by the flexible screen is located in the recess is a three-dimensional fingerprint in a recess shape.
Step S540, judging whether the shape of the fingerprint accords with the shape of the preset concave fingerprint, and determining whether to execute the preset operation according to the judging result.
In prior art solutions, a comparison between planar fingerprints is performed when fingerprint verification is performed. In the technical scheme of the embodiment, the comparison between the stereoscopic fingerprints and the plane fingerprints is specifically shown in fig. 6, and when the touch operation pressure of the user is too large or too small, the formed stereoscopic fingerprints are too concave or too flat, and even if the textures of the fingerprints are the same, the verification cannot be performed. Therefore, the technical scheme based on the embodiment improves the complexity of fingerprint verification and ensures the safety of operation control based on fingerprints.
As shown in fig. 7, in one embodiment of the present invention, a mobile terminal is provided that includes a processor 710, a memory 720, a communication bus 730, a flexible screen 740, a first sensor 750, and a second sensor 760.
Communication bus 730 is used to enable connected communication between processor 710 and memory 720.
The flexible screen 740 is used to accept a touch operation by a user.
In this embodiment, the flexible screen may be deformed under the touch operation of the user, and with the development of the flexible screen technology, more mobile terminals such as mobile phones and tablet computers adopt the flexible screen.
The first sensor 750 is used to collect characteristics of the touch operation.
In this embodiment, the feature of the touch operation performed by the user is not limited, and any feature of the touch operation and any information related to the touch operation may be used as the feature of the touch operation, and the type of the first sensor corresponds to the feature of the touch operation.
The second sensor 760 is used to collect a fingerprint when a user performs a touch operation.
The processor 710 is configured to execute a fingerprint-based operation control program stored in the memory 720 to implement the steps of:
and judging whether the characteristics of the touch operation meet preset conditions.
In the present embodiment, the following examples are provided for acquiring the characteristics of the touch operation, and the following description is made for any judgment as to whether the characteristics of the touch operation meet the preset conditions.
(1) And collecting the pressure of the flexible screen corresponding to the touch operation.
In this embodiment, the pressure of the touch operation is the strength of the fingerprint identification area pressed by the user each time, and because the flexible screen has the characteristic of pressing compression, the user can easily perceive and memorize the corresponding pressing strength, so that the touch pressure of the user can be used as a feature of the touch operation. The mobile terminal is provided with a pressure sensor for collecting the pressure of the touch operation of the user, and specifically, the pressure sensor can be located in a flexible screen, namely, the flexible screen is a pressure screen.
The judgment of the pressure based on the touch operation can be divided into the following two ways:
simple mode: and judging that the pressing force of the user is in accordance with the condition when the pressing force of the user is smaller than or larger than a proper threshold set by the user (for example, the user sets a certain pressing threshold, and the pressing force larger than the threshold is used for encryption initialization), and judging that the pressing force is in accordance with the condition as long as the pressing force of the subsequent user is larger than the pressing force of the user, and judging whether the subsequent fingerprint based on the acquired fingerprint triggers a specific operation or not).
Complex mode: in the mode, whether the pressing force meets the condition is judged, and the two standards of pressing light or heavy are not simply pressed any more, but the force size ranges are strictly distinguished, if the user sets three ranges of small, medium and large, the set thresholds are respectively: small-medium=10, medium-large=20, and when judging whether the pressing force meets the condition, it is necessary to judge whether the force falls in three check intervals—small: [0, 10], wherein: [8,22], dai [18,10000]. It should be noted that, the check interval is not set strictly according to the threshold value set by the user, and this is because the user may not be completely accurate in sensing the strength of the user, so when the strength of the user is checked, a certain error may be allowed in the strength of the user, for example, when the strength of the user is set to be 20 as the threshold value of the strength encryption size interval, the actually set interval is [18,10000], when the strength of the user is pressed by >18, that is, the pressure is determined to be in the large interval, and when the user sets to be 20 as the threshold value of the encryption interval, the actually set interval is [8,22], and when the pressing strength is 22, that is, the pressure is determined to be in the middle interval.
(2) The touch times when the user performs the touch operation are obtained.
In this embodiment, the pressing number verification may be implemented: when triggering a specific operation based on a fingerprint, the user needs to press for a certain number of times, the number of times can be set by the user, the number of times n > =1, and n=1 is that the user only needs to perform one pressing operation, and the user can trigger the specific operation under the conditions that the user presses the flexible screen once and the fingerprint is correct in verification. When n > =2, the number of times the user presses the flexible screen is recorded every time the user presses the flexible screen, and when the user completes n presses and the fingerprint verification is correct, the specific operation can be triggered. If the user sets n=2, the user lightly presses the finger with the thumb of the right hand for the first time, presses the finger with the index finger of the right hand for the second time, and after the user pressing times reach 2 times, the fingerprint pressed by the index finger of the right hand for the second time is collected.
(3) The magnitude of deformation of the flexible screen caused by touch operation is acquired.
In this embodiment, since the flexible screen is used on the mobile terminal, the flexible screen is deformed under the touch operation of the user, that is, the flexible screen is recessed toward the inner direction of the mobile terminal, as shown in fig. 4. Therefore, the deformation amplitude of the flexible screen can be detected through the preset detection, and when the actual change amplitude of the flexible screen exceeds a certain amplitude or is smaller than a certain amplitude, the condition is judged to be met, and the subsequent fingerprint acquisition operation can be performed. According to the technical scheme, the characteristics of the flexible screen are fully utilized, the verification of touch operation of a user is realized, and the safety of operation control based on fingerprints is improved.
In the present embodiment, the above three ways of acquiring a touch operation may also be used in combination.
And when the judgment result is yes, judging whether to execute the preset operation according to the fingerprint.
In the present embodiment, the type of the preset operation is not limited, and for example, unlocking, payment, opening of the private data, and the like may be performed based on the fingerprint.
According to the technical scheme of the embodiment, when a user performs touch operation on the flexible screen, whether to perform preset operation is not directly judged based on the fingerprint after the fingerprint of the user is acquired, but the characteristics of the touch operation of the user are firstly acquired, and judgment is performed once in advance based on the characteristics of the touch operation of the user to judge whether operation control based on the fingerprint is necessary or not.
In one embodiment of the invention, a mobile terminal is provided that includes a processor 710, a memory 720, a communication bus 730, a flexible screen 740, a first sensor 750, and a second sensor 760.
Communication bus 730 is used to enable connected communication between processor 710 and memory 720.
The flexible screen 740 is used to accept a touch operation by a user.
The first sensor 750 is used to collect characteristics of the touch operation.
The second sensor 760 is used to collect a fingerprint in a concave shape in case that the flexible screen is concave by a touch operation.
The processor 710 is configured to execute a fingerprint-based operation control program stored in the memory 720 to implement the steps of:
and judging whether the characteristics of the touch operation meet preset conditions.
The fingerprints collected in the prior art solutions are planar fingerprints, whereas the fingerprints collected in the technical solutions of the present embodiment are not planar fingerprints, but rather "stereoscopic" fingerprints. In this embodiment, since the flexible screen of the mobile terminal is deformed under the pressure of the touch operation of the user, that is, the recess is generated, and the fingerprint is in contact with the recess of the flexible screen when the finger of the user touches the flexible screen, whether the fingerprint sensed by the flexible screen is located in the recess is a three-dimensional fingerprint in a recess shape.
Judging whether the shape of the fingerprint accords with the shape of the preset concave fingerprint, and determining whether to execute preset operation according to the judging result.
In prior art solutions, a comparison between planar fingerprints is performed when fingerprint verification is performed. In the technical scheme of the embodiment, the comparison between the stereoscopic fingerprints and the plane fingerprints is specifically shown in fig. 6, and when the touch operation pressure of the user is too large or too small, the formed stereoscopic fingerprints are too concave or too flat, and even if the textures of the fingerprints are the same, the verification cannot be performed. Therefore, the technical scheme based on the embodiment improves the complexity of fingerprint verification and ensures the safety of operation control based on fingerprints.
