Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of a first flowchart of a fingerprint identification method based on a touch screen according to an embodiment of the present invention, where as shown in the figure, the method of the present invention includes the following steps:
step S101, acquiring a click position of a user on a touch screen of the terminal equipment and corresponding fingerprint information.
The embodiment of the invention is applied to the terminal equipment, the display area of the terminal equipment is provided with the acquisition module, the acquisition module can comprise a fingerprint acquisition module under a screen, and when a user performs touch operation on the terminal equipment, the acquisition module acquires fingerprint information of the user.
Before step S101, the user has completed configuring a fingerprint for touchscreen fingerprinting on the terminal device and using the fingerprint the location on the touchscreen that needs to be clicked.
In step S101, when the user operates the terminal device, if the user wants to perform fingerprint identification on the touch screen, the user clicks on the touch screen by using a previously preset fingerprint, and at this time, the touch screen of the terminal device acquires a click position of the user and fingerprint information at the click position, so as to provide subsequent steps for operation.
Step S102, when the click position is matched with the fingerprint identification position and the fingerprint information corresponding to the click position is matched with a preset fingerprint template, determining that the fingerprint identification is successful; wherein, the relative position of the fingerprint identification position on the touch screen is configurable.
In step S102, the click position is a position where the finger of the user clicks on the touch screen, the preset fingerprint template is a fingerprint preset on the terminal device by the user for fingerprint identification, and the fingerprint identification position is a position where the user needs to click on the touch screen when performing fingerprint identification using the fingerprint. When the user operates the terminal device, the fingerprint information corresponding to the click position is matched with the preset fingerprint template, which means that the fingerprint information of the corresponding user finger provided by the terminal device when the terminal device acquires that the user finger clicks at the click position is the same as or extremely similar to the preset fingerprint template. The matching of the click position and the fingerprint identification position means that the position where the finger of the user clicks on the touch screen is the same as or overlaps with the position where the finger needs to be clicked on the touch screen for fingerprint identification by using the fingerprint.
In this step, the relative position of the fingerprint identification position on the touch screen is configurable, that is, the fingerprint identification position may be self-selected by the user when the user performs the preset configuration of the touch screen fingerprint identification, and the fingerprint identification position may be, but is not limited to, at the left edge, the right edge, the upper edge, the lower edge, or any other position of the touch screen. There can be one or more user-configured fingerprint identification locations.
In this step, it may be determined whether the click position matches the fingerprint identification position, and if the click position matches the fingerprint identification position, it may be determined whether the fingerprint information corresponding to the click position matches the preset fingerprint template. Or judging whether the fingerprint information corresponding to the click position is matched with a preset fingerprint template or not, and judging whether the click position is matched with the fingerprint identification position or not if the fingerprints are matched with each other. Or, judging whether the fingerprint is matched with the position, and then taking the set of the judgment results of the fingerprint and the position as the output result of the step.
In this step, the relative position of the fingerprint identification position in the touch screen is configured based on time, and this step may further include: and when the click position is matched with the fingerprint identification position corresponding to the current time and the fingerprint information corresponding to the click position is matched with the preset fingerprint template, determining that the fingerprint identification is successful. The fingerprint identification positions can be arranged at different relative positions in the touch screen at different time points or time periods according to the configuration of a user, for example, the fingerprint identification positions are arranged at the upper half part of the touch screen in an operating period from 9 points to 18 points, and the fingerprint identification positions are arranged at the lower half part of the touch screen in a non-operating period from 18 points to 9 points on the next day. When a user operates the terminal equipment in the working period, the user uses a correct finger to click the upper half part of the touch screen, at the moment, the click position is matched with the fingerprint identification position corresponding to the current time, the correct finger provides correct corresponding fingerprint information, the fingerprint information is matched with a preset fingerprint template, and the terminal equipment can determine that the fingerprint identification is successful.
The fingerprint identification position can be configured at the upper left corner of the touch screen on Monday to Friday, and the fingerprint identification position can be configured at the lower right corner of the touch screen on Saturday and Sunday. The fingerprint identification position can also be configured to be firstly identified in the left half part of the touch screen, secondly identified in the right half part of the touch screen, and thirdly identified in the left half part of the touch screen.
In this step, this step may further include: when the click position is matched with the fingerprint identification position corresponding to the current sequence and the fingerprint information corresponding to the click position is matched with the preset fingerprint template, determining that the fingerprint identification is successful; and after the fingerprint identification is determined to be successful, updating the fingerprint identification positions according to a preset sequence. The touch screen is divided into a plurality of clicking areas, the clicking areas are numbered based on a set sequence, and the preset sequence is a combination of the clicking areas based on the numbers. That is, the fingerprint identification position can have a plurality of relative positions in the touch screen according to the configuration of the user, for example, the touch screen is divided into nine areas with numbers 1 to 9 according to the sequence from left to right and from top to bottom, the user configures the areas with numbers 1, 3, 5 and 9 as the fingerprint identification position, and configures the preset sequence of numbers 9, 3, 5 and 1 for the fingerprint identification position.
When a user operates the terminal equipment based on the sequence to perform first fingerprint identification, and a correct finger is used for clicking the area with the number 9 in the touch screen, the clicking position is matched with the fingerprint identification position corresponding to the current time, the correct finger provides correct corresponding fingerprint information, the fingerprint information is matched with a preset fingerprint template, and the terminal equipment can determine that the fingerprint identification is successful. And then when the user operates the terminal equipment to perform second fingerprint identification, when the correct finger is used for clicking the area with the number 3 in the touch screen, the clicking position is matched with the fingerprint identification position corresponding to the current time again, the correct finger provides the correct corresponding fingerprint information, the fingerprint information is matched with the preset fingerprint template, and the terminal equipment can determine that the second fingerprint identification is successful. The user should click the area with the number 5 in the touch screen when fingerprint identification is carried out for the third time, click the area with the number 1 in the touch screen when fingerprint identification is carried out for the fourth time, click the area with the number 9 in the touch screen based on the preset sequence when fingerprint identification is carried out for the fifth time, and analogize the fingerprint identification position of follow-up touch screen fingerprint identification.
That is to say, the terminal device may obtain the order of the digits that should adopt the preset order after taking the remainder of the number of fingerprint identification positions in the preset order divided by the number of times of fingerprint identification performed by the user on the touch screen. For example, when the user performs the touch screen fingerprint identification for the 17 th time, 5 fingerprint identification positions are arranged in the preset sequence, and the remainder of dividing 17 by 5 is 2, so that it can be known that the fingerprint identification for the 17 th time needs to perform the fingerprint identification by using the 2 nd fingerprint identification position in the preset sequence. Further, when the user performs the 20 th time of touch screen fingerprint identification, the remainder of dividing 20 by 5 is 0, then the 20 th time of fingerprint identification uses the 5 th fingerprint identification position in the preset sequence to perform fingerprint identification, and so on for the fingerprint identification positions of the subsequent touch screen fingerprint identification.
In this step, the user can be prompted with information of the current order based on the fingerprint identification position corresponding to the current order. For example, if the fingerprint identification position corresponding to the current sequence is the 3 rd fingerprint identification position in the preset sequence, 3 or information related to 3 can be provided.
In this step, the preset fingerprint templates corresponding to the fingerprint identification positions are the same, or at least two preset fingerprint templates in the preset fingerprint templates corresponding to the fingerprint identification positions are different. That is, a single fingerprinting location may correspond to one or more fingerprints. For example, when the user configures the fingerprint identification position in the upper half of the touch screen, only the preset fingerprint template of the right thumb is configured, and the preset fingerprint templates of the left thumb and the left index finger are configured when the fingerprint identification position is in the lower half of the touch screen.
Fig. 2 is a second flowchart of a touch screen-based fingerprint identification method according to an embodiment of the present invention, and fig. 2 provides a further touch screen-based fingerprint identification method according to an embodiment of the present invention. Steps S201 and S202 in fig. 2 are the same as steps S101 and S102 in fig. 1, and a description thereof will not be repeated. Fig. 2 adds step S200 to fig. 1, and the detailed description about the adding step is as follows:
and step S200, setting the range of the fingerprint identification position in a frame selection mode, or setting the range of the fingerprint identification position through the pressing time length.
In step S200, when the user performs the preset configuration of the touch screen fingerprint identification, the user can independently select the relative position of the fingerprint identification position on the touch screen, and simultaneously determine the range size of the fingerprint identification position, and set the range size or the pressing duration through frame selection. The frame selection refers to that a user pulls out a frame on a touch screen in a dragging mode by using a finger, a touch pen, a mouse or the like to circle the range of the fingerprint identification position. The pressing duration setting means that the user does not leave the touch screen or the clicking position after clicking on the touch screen by using a finger, a touch pen or a mouse and the like, the sash gradually expands towards the periphery by taking the clicking position as the center, and the range of the fingerprint identification position selected by the sash is controlled along with the stay time of the finger, the touch pen or the mouse at the clicking position.
In this step, the fingerprint identification position can be a square area with 1 cm multiplied by 1 cm or 100 pixels multiplied by 100 pixels, a circular area with a diameter of 2 cm or 200 pixels, or an irregular area. There can be one or more fingerprint recognition locations.
In the embodiment of the invention, the fingerprint identification method based on the touch screen can bring new use safety experience for a user to operate the terminal equipment, and the function of self-configuring the fingerprint identification position by the user is provided, so that the safety of the fingerprint identification of the touch screen can be improved, and the defect that the existing fingerprint identification only depends on the fingerprint as a safety guarantee is overcome.
In addition, through the user configuration fingerprint identification position by oneself, non-user's invader will not follow and learn what kind of position should carry out fingerprint identification from terminal device touch-sensitive screen, also can not follow the size of learning this fingerprint identification position scope, can't accurately click in the within range of fingerprint identification position, so can increase touch-sensitive screen fingerprint identification's complexity, further reach the effect that promotes touch-sensitive screen fingerprint identification security.
In addition, the first-stage check can be performed by judging whether the click position is matched with the fingerprint identification position, so that the operation load and the power consumption of the terminal device for directly performing fingerprint matching check are reduced.
In addition, through fingerprint identification position based on time configuration, the user can dispose different time points or different fingerprint identification positions of time interval collocation by oneself, increases touch-sensitive screen fingerprint identification's complexity, further reaches the effect that promotes touch-sensitive screen fingerprint identification security.
In addition, through the order of predetermineeing of a plurality of fingerprint identification position collocation, the user more can guarantee that fingerprint identification all uses different relative position on the touch-sensitive screen at every turn, ensures the average use of fingerprint collection module under the screen to make and can not leave apparent fingerprint sweat stain in specific position on the touch-sensitive screen, and then let the non-user can obtain the fingerprint identification position easily, also can avoid the fingerprint collection module under the screen of specific area to use excessively and cause the discernment ability to descend.
