detailed description

The present invention provides a method and an apparatus for unlocking a touch screen terminal. In order to make the objects, technical solutions and effects of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings.

The touch screen terminal of the present invention is an electronic terminal with a touch screen, and can be a portable electronic terminal with a touch screen mobile phone, a computer, a tablet, an MP3, an MP4, a PSP, a POS machine, and the like. The touch screen is used for display and touch screen operation. In order to prevent misoperation and illegal use by others, the touch screen terminal is now set to manually lock the screen, or automatically enters the locked state when no operation or touch is detected within a preset time. When the touch screen of the terminal is in a locked state, the user cannot perform a 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 position of the first contact point of the contact and the behavior recognition of the contact area are unlocked by the touch screen, and the unlocking fun and user experience are improved while ensuring the unlocking security of the touch screen terminal.

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

Step S10: When the touch screen 30 of the terminal is in a locked state, contact with the touch screen 30 is detected.

Step S20: When the contact with the touch screen 30 is detected, an imitation fingerprint collection area 40 is displayed on the touch screen 30, wherein the preset fingerprint image 50 is displayed in the imitation fingerprint collection area 40.

The fingerprint-like fingerprint collection area 40 is an area for simulating the fingerprint of the user, and the size thereof may be set to be slightly larger than the general fingerprint size and the area of the area is about twice the area of the general fingerprint, and the position may be set at the touch screen 30. The center position or other specific location is fixed.

As another preferred alternative, as shown in FIG. 2, the fingerprint-like collection area 40 may also be disposed to be displayed with the contact point 20 as a center position, so that the user can touch any position of the touch screen 30, and the fingerprint-like fingerprint collection is performed. The area 40 is also generated following the user's contact point, which enhances the user's touch screen unlocking pleasure, and also ensures that the user's finger is just above the fingerprint-like collection area 40 after the imitation fingerprint collection area 40 is displayed or In the vicinity, the user also needs to move the hand to find the fingerprint-like collection area displayed by other fixed positions, which saves the operation time of subsequent pressing contact in the fingerprint-like collection area 40, and improves the unlocked user experience.

On the basis of the foregoing embodiment, in order to further enhance the concealment of the fingerprint touch unlocking and the concealment of the actual unlocking behavior, and improve the interest of the touch screen unlocking, the fingerprint-like collection area in the first embodiment of the present invention 40 can be further set or modified.

In another embodiment of the present invention, a scanning beam that continues to reciprocate is displayed inside the fingerprint-like acquisition area 40 to further simulate a fingerprint collection interface. Since the scanning beam in the fingerprint image is a general animation effect of prompting the user to input the fingerprint, the fingerprint image displayed in the embodiment of the present invention, the animation effect of the continuous reciprocating motion of the scanning beam, and the user's finger pressing and contacting the fingerprint-like collection area 40 may It is extremely deceptive, and makes others mistakenly believe that the user is using the touch screen to collect fingerprints for verification and unlocking, and at the same time, the interest of the touch screen unlocking is improved.

In another embodiment of the present invention, a scanning beam of continuous cyclic motion is displayed on the edge of the fingerprint-like acquisition area 40, and the fingerprint collection interface is further simulated, and the realism of the fingerprint capture of the simulated touch screen and the concealment of the actual unlocking behavior are enhanced. Sex, while improving the fun of touch screen unlocking.

Step S30: detecting a press contact with the fingerprint-like fingerprint collection area 40, and acquiring a position and a contact area of the first contact point of the press contact.

When the user presses the fingerprint-like collection area 40 of the touch screen 30 with a fingertip, the touch screen 30 first detects the position of the first contact point, and then with the fingertip fingerprint completely with the fingertip When the touch screen 30 is in contact with the contact, the contact between the two contacts becomes a contact of the face by the contact of a single point. Moreover, the contact area of the fingertip pressing contact gradually increases as the pressing force increases, up to the maximum contact area. Therefore, when pressing the contact, the user can control the position range and the contact area of the first contact point by slightly adjusting the position, angle and force of the fingertip pressing, and it is difficult for others to observe or guess the user preset. The effective area and the contact area range of the first contact point, it is even impossible to think that the touch screen unlocking method of the present invention limits the effective area and the contact area of the preset first contact point, but simply considers that the user is only passing the touch screen. Capture fingerprints for unlocking.

Step S40: If it is detected that the first contact point falls within the preset area in the fingerprint-like fingerprint collection area 40 and the contact area falls within the preset area, the terminal is switched to the unlocked state of the user interface.

It can be understood that if it is detected that the first contact point does not fall within the preset area in the fingerprint-like collection area 40 and the contact area does not fall within the preset area, the terminal is kept locked by the user interface. .

The step of determining whether the first contact point falls within the preset area in the fingerprint-like fingerprint collection area 40 includes: acquiring the position of the fingerprint-like fingerprint collection area 40; acquiring a preset area position range of the first contact point; Whether the position of the first contact point falls within the preset area position range.

Further, before the unlocking by the unlocking method of the touch screen terminal, the method further includes the step of presetting the area of the first contact point in the fingerprint-like acquisition area 40: dividing the fingerprint-like collection area 40 into multiple areas. ; set at least one area as the effective contact area of the first contact point. Referring to FIG. 3, the fingerprint-like fingerprint collection area 40 is divided into 6 columns and 3 rows of 18 regions, and the 5th row and the 3rd region 60 are set as effective contact regions of the first contact point. Here, the effective contact area of the first contact point is not the fixed area position of the touch screen 30, but the relative area position in the fingerprint-like collection area 40 is the position of the fingerprint-like collection area 40. Change and change. Of course, the way of dividing the area, the number of the area, the location and the number of the first contact point effective area can be personalized according to the user's preference and security requirements. Preferably, the boundary of the divided area can also be displayed on the touch screen so that the user can quickly and accurately find the effective contact area of the first contact point.

Similarly, further, before unlocking by the unlocking method of the touch screen terminal, the method further includes the step of setting a preset contact area range: detecting a maximum contact area when the fingertip is pressed into contact with the touch screen; and setting the preset contact area to be The ratio of the maximum contact area. In a specific implementation, the user presses the fingertip slightly in parallel with the touch screen to make the fingertip completely fit so as to obtain the maximum contact area, and the preset contact area range can be personalized according to personal preference, such as setting the maximum contact area. 30% to 50%, when the user unlocks the touch screen, the fingertip needs to be slightly raised to a larger angle so that the actual pressing contact area falls within the preset area.

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 position of the first contact point and the pressing contact when the user unlocks. The behavior of the contact area is triggered to unlock, and it is difficult for others to observe or break the effective contact area and the pressing contact area of the first contact point of the user's preset pressing contact, which is extremely concealed and even almost impossible to think of. Limiting the position and contact area of the first contact point to the unlocking condition 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.
