detailed description

The present invention provides a method and an apparatus for unlocking a touch screen. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Touch screens have been widely used in mobile phones, computers, tablets, MP3, MP4, PSP, POS and other electronic devices. In order to prevent misuse and illegal use by others, there are now touch screen settings that can manually lock the screen, or automatically enter the locked state when no operation or touch is detected within the preset time. When the touch screen is in the locked state, the user cannot perform the touch operation through the touch screen, thereby effectively avoiding misoperation and illegal operation by others.

Under the prior art, the touch screen itself cannot directly collect high-quality fingerprint images for identity verification, and the purpose of the present invention is to provide a method for unlocking a fingerprint, simulating a fingerprint for unlocking the touch screen, and substantially pressing The contact recognition of the contact contact time and the position of the first contact point is unlocked by the touch screen, and the unlocking fun and user experience are improved while ensuring the security of the touch screen unlocking.

Referring to FIG. 1 and FIG. 2, a touch screen unlocking method according to a first embodiment of the present invention includes the following steps:

Step S10: When the touch screen 30 is in the locked state, an imitation fingerprint collection area 40 of the built-in preset fingerprint image 50 is displayed.

The fingerprint-like fingerprint collection area 40 is an acquisition area for simulating the collection of user fingerprints, and the size thereof may be set to be slightly larger than a general fingerprint size and the area of the area is about 1.5 times the fingerprint area of the user's fingertip, and the position may be set to be in the The center position of the touch screen 30 or other specific position is fixedly displayed. The fingerprint image 50 may be a fixed fingerprint image or a fingerprint image set by the user, which is filled and displayed at the center of the fingerprint collection area 40.

Step S20: detecting a press contact with the fingerprint-like fingerprint collection area 40, and acquiring a contact time of the press contact and a position of the first contact point.

In the first embodiment of the invention, the contact time of the press contact is obtained by the touch screen 30 device detecting the time from the start of the contact to the end of the process. It can be understood that, in order to facilitate the user to acquire and control the time of each pressing contact, the contact time of the user's pressing contact can be dynamically displayed on the touch screen 30 when the user presses the contact, and the user can conveniently determine and control the pressing contact. Contact time.

Of course, in order to allow the user to intuitively determine and control the contact time of the pressing contact, the realism of the fingerprint touch image capture and the pressing contact time of the simulated touch screen are enhanced as the concealment of the unlocking condition, and the interest of the touch screen unlocking is improved. The contact time of the contact can be obtained by the following embodiments or other means.

In another embodiment of the present invention, a scanning beam with a constant speed and continuous reciprocating motion is displayed inside the fingerprint-like collection area 40, further simulating the fingerprint collection interface, and also allowing the user to intuitively determine the moving distance or the round-trip path of the scanning beam. The contact time of the press contact is determined by dividing the distance of the scanning beam movement by a preset speed. Specifically, in the embodiment of the present invention, the scanning beam is arranged to reciprocate up and down in the center of the fingerprint-like collection area 40 at a fixed speed of one round trip per second, and the scanning beam starts to go from top to bottom when the user presses the contact. Movement, when the scanning beam is moved halfway to the lower end of the fingerprint-like acquisition area 40, the user can intuitively determine that the pressing contact time is 1.5 seconds, so that the user can control the time of the pressing contact according to the moving distance of the scanning beam. In this embodiment, the displayed fingerprint image, the animation effect of the scanning beam continuing to reciprocate motion, and the user's finger pressing and contacting the fingerprint-like fingerprint collection area 40 cause great deception, causing others to mistakenly believe that the user is collecting through the touch screen 30. The fingerprint is verified and unlocked. Moreover, the scanning beam in the fingerprint image is a universal animation effect of prompting the user to input a fingerprint, and the process of intuitively controlling the time of pressing the contact by controlling the moving distance of the scanning beam when the user presses the unlocking is difficult to be observed or even guessed by others. It has a strong concealment and improves the fun of unlocking the touch screen.

In still another embodiment of the present invention, a scanning beam of a uniform continuous cyclic motion is displayed at the edge of the fingerprint-like acquisition area 40 to further simulate a fingerprint collection interface, and at the same time, the user intuitively determines the moving distance of the scanning beam. The contact time of the contact is determined by the distance traveled by the scanning beam and the preset speed. Specifically, in the embodiment of the present invention, the scanning beam is arranged to circulate clockwise or counterclockwise at the edge of the fingerprint-like acquisition area 40 at a fixed speed of a closed loop every 2 seconds, and the user is detected when the pressing contact is detected. The beam starts to move from the position of 12 o'clock. When the scanning beam moves 1.25 closed loops to reach the position of the fingerprint capture area 40 at three o'clock, the user can intuitively determine that the pressing contact time is 2.5 seconds, so that the user can The moving distance of the scanning beam is a good control of the time of pressing the contact.

In still another embodiment of the present invention, the edge of the fingerprint-like collection area 40 continuously changes color continuously according to a preset color sequence, so that the user intuitively determines the process of color change, and the contact time of the press contact is through the The color of the start of the contact is pressed and the preset color change speed is determined. It can be understood that the control principle of the pressing contact time in this embodiment is similar to the above-mentioned embodiment, and reference may be made to the specific implementation details of the foregoing embodiments, and details are not described herein again.

When the user presses the finger-like fingerprint collection area 40 of the touch screen 30 with a fingertip, the touch screen 30 first detects the first contact point, and then gradually contacts the touch screen 30 with the fingertip fingerprint, The contact between the contacts is changed from the contact of a single point to the contact of the face. Therefore, when pressing the contact, the user can control the position range of the first contact point by slightly adjusting the position and angle of the fingertip pressing, and it is difficult for others to observe or guess the first contact point preset by the user. The location range is even impossible to imagine that the touch screen unlocking method of the present invention limits the position range of the preset first touch point, but simply considers that the user only unlocks the fingerprint through the touch screen 30.

Step S30: If the contact time of the pressing contact is detected, and the position of the first contact point falls within a preset contact time range and a preset first contact point position range, the terminal is converted to the user. The unlocked state of the interface.

It can be understood that if it is detected that the contact time of the pressing contact and the position of the first contact point do not fall within the preset contact time range and the preset first contact point, respectively, the The terminal maintains the locked state of the user interface. Here, the user may display a prompt or a voice broadcast through the touch screen 30 to prompt the user to verify the fingerprint error. Please re-enter the fingerprint and other information.

Further, before unlocking by the touch screen unlocking method described above, the time range of the press contact should also be set in advance, and can be set according to the user's operating habits and the degree of difficulty in cracking. For example, the time range for setting the pressing contact is 0.5-1 second, and the time range setting is very short, which is beyond the time range of 2-3 seconds of the conventional fingerprint collection. When the user touches the fingerprint-like fingerprint collection area 40, the other person can only It is simply considered that the user only unlocks the fingerprint by the touch screen 30, and it is difficult to observe or guess the preset contact time range of the user, and it is even impossible to think that the touch screen unlocking method of the present invention limits the contact time of the pressing contact.

Similarly, further, before the unlocking by the touch screen unlocking method described above, the position range of the first contact point of the press contact should also be set in advance. Referring to FIG. 3, in the embodiment, the step of presetting the position range of the first contact point of the pressing contact comprises: clicking on any point in the fingerprint-like fingerprint collection area 40, such as clicking on the contact point 60, generating the click. A contact area 60 is a circular area 70 centered on a predetermined size; a region overlapping the circular area 70 with the fingerprint-like collection area 40 (ie, the circular area 70 in FIG. 3) is set as a pre- Set the position range of the first contact point of the press contact.

Of course, the position range of the first contact point of the pressing contact here can also be set according to the operation habit of the user pressing the fingerprint-like collection area 40 and the degree of difficulty in unlocking. For example, the user generally performs a pressing contact operation with the right finger tip, so that the click contact point is not easily detected or cracked if it is disposed in the upper left area of the fingerprint-like collection area 40. In addition, the size of the circular area can be controlled by setting the radius size of the circular area, thereby controlling the difficulty of unlocking. For example, the larger the radius, the larger the circular area, and the area overlapping with the fingerprint-like collection area 40. (The range of the position of the first contact point of the preset pressing contact) is larger, and the first contact point of the user is more likely to fall within the preset range when the user presses the contact. This unlocking condition is easier to implement, and the radius of the set is more Smaller unlocking is more difficult. In practical applications, when the click contact point position is relatively close to the edge of the fingerprint-like fingerprint collection area 40 or the radius size setting is relatively large, the generated circular area may exceed the edge of the fingerprint-like fingerprint collection area 40, and the first contact of the fingerprint contact area is pressed. The position range of the contact points is still set to the area where the two overlap.

It can be seen that the unlocking method of the touch screen device provided by the present invention is to simulate the user to collect the fingerprint of the user through the touch screen 30 for fingerprint identity verification, and substantially determines the contact time and the first contact point of the pressing contact when the user unlocks. The behavior of the position is triggered to unlock, and it is difficult for others to observe or crack the contact time of the user's preset pressing contact and the position of the first contact point, which is extremely concealed, and it is almost impossible to think of the contact time. The position of the first contact point is defined as an unlocking condition, which improves the security of the touch screen unlocking. In addition, the appearance of the simulated fingerprint recognition is extremely deceptive, which can make others mistakenly believe that the touch screen device must collect fingerprints for unlocking, which acts as a deterrent to the illegal unlocking behavior, effectively suppressing the intention of others to attempt illegal unlocking. This also indirectly improves the security of the touch screen unlocking. At the same time, the analog touch screen captures the fingerprint unlocking scheme, which also improves the interest of unlocking and enriches the user's touch screen operation experience.
