Namely, when the touch display screen detects the touch of a user, the fingerprint information is acquired through the fingerprint sensing module under the screen. When the finger of the user contacts the touch display screen, the fingerprint information of the finger is acquired by the fingerprint sensing module under the screen, and the touch display screen detects the touch moment of the user and can be regarded as the input moment of the fingerprint information of the first input.
In other embodiments, the electronic device may further include a proximity sensor, and the acquiring at least two pieces of fingerprint information sequentially input on the display screen for a preset time may further include: when the proximity sensor detects that objects such as fingers are close to the touch screen, at least two pieces of fingerprint information which are input on the display screen in sequence within preset time are acquired in sequence through the under-screen fingerprint sensing module at the corresponding position. When the finger of the user is close to the display screen and is close to the sensor, the fingerprint information of the finger is generally acquired by the fingerprint sensing module under the screen at the same time, and the proximity sensor detects the moment when objects such as the finger are close to the sensor and can also be regarded as the input moment of the fingerprint information of the first input.
In some application scenarios, when a user needs to unlock a screen or log in an application program or pay, at least two pieces of fingerprint information can be sequentially input on the display screen within a preset time.

In some embodiments, the at least two pieces of fingerprint information are included in the derived fingerprint information string, and the at least two pieces of preset fingerprint information are included in the preset fingerprint information string. That is, the fingerprint information string is formed by combining the at least two pieces of fingerprint information that are sequentially input, and the order of combining is not limited.
Correspondingly, the determining whether the fingerprint information string matches with a preset fingerprint information string includes: comparing at least two pieces of fingerprint information in the fingerprint information string with at least two pieces of preset fingerprint information in a preset fingerprint information string; and when determining that at least two pieces of fingerprint information in the fingerprint information string are respectively matched with at least two pieces of preset fingerprint information in a preset fingerprint information string, determining that the fingerprint information string is matched with the preset fingerprint information string. Otherwise, it is determined that the fingerprint information string is not matched with the preset fingerprint information string, that is, when it is determined that a certain piece of fingerprint information in the fingerprint information string is not matched with any preset fingerprint information in the preset fingerprint information string, it is determined that the fingerprint information string is not matched with the preset fingerprint information string.
In other embodiments, the fingerprint information string includes the at least two pieces of fingerprint information and an input order of each piece of fingerprint information, and the preset fingerprint information string includes at least two pieces of preset fingerprint information and an order of each piece of preset fingerprint information. That is, in another embodiment, the fingerprint information string is formed by sequentially combining at least two pieces of input order of the fingerprint information, and the fingerprint information string includes not only the at least two pieces of fingerprint information but also information of the input order of each piece of fingerprint information.
Correspondingly, the determining whether the fingerprint information string matches with a preset fingerprint information string includes: comparing at least two pieces of fingerprint information in the fingerprint information string with preset fingerprint information in a corresponding sequence in a preset fingerprint information string according to the input sequence of each piece of fingerprint information in the fingerprint information string; and when determining that each piece of fingerprint information in the fingerprint information string is matched with the preset fingerprint information in the corresponding sequence in the preset fingerprint information string, determining that the fingerprint information string is matched with the preset fingerprint information string. Otherwise, determining that the fingerprint information string is not matched with a preset fingerprint information string, namely determining that the fingerprint information string is not matched with the preset fingerprint information string when determining that any fingerprint information in the fingerprint information string is not matched with the preset fingerprint information in the corresponding sequence in the preset fingerprint information string.
Therefore, in another embodiment, matching the fingerprint information string with the preset fingerprint information string not only requires that each fingerprint information in the fingerprint information string matches with each preset fingerprint information in the preset fingerprint information string, but also the input sequence of each fingerprint information in the fingerprint information string is the same as the sequence of the preset fingerprint information in the preset fingerprint information string, thereby further improving the security.
In some embodiments, the fingerprint information matching the preset fingerprint information means that the similarity between the fingerprint information and the corresponding preset fingerprint information exceeds a preset threshold, for example, the similarity exceeds 95%.

107. And unlocking the object to be unlocked.
In some embodiments, unlocking the object to be unlocked includes allowing use of a function associated with the object to be unlocked, logging in the object to be unlocked, confirming payment verification is passed, and the like. For example, as described above, when the object to be unlocked is the display screen, the object to be unlocked is unlocked to unlock the display screen and enter an unlocked interface such as a desktop of the electronic device, so that the electronic device can be used. And when the object to be unlocked is the application program, unlocking the object to be unlocked to log in the application program or determine that the payment verification is passed and the like. When the object to be unlocked is determined to be the application program corresponding to the target application icon, unlocking the object to be unlocked is also performed by logging in the application program or allowing to view personal data of the application program and the like.
Particularly, when an interface comprising a plurality of application icons is displayed on a display screen, a target application icon is determined according to the input positions of the at least two pieces of fingerprint information, and when the application program corresponding to the target application icon is determined to be the object to be unlocked, the application program corresponding to the target application icon is unlocked. Therefore, the fingerprint information can be sequentially input on the target application icon or around the target application icon, the application program corresponding to the target application icon can be quickly unlocked after the verification is passed, the user can unlock the application program corresponding to the application icon by touching the application icon, and the unlocking convenience is greatly improved.
Therefore, in the application, when at least two pieces of fingerprint information are input in sequence and each piece of fingerprint information is matched and verified, the object to be unlocked is unlocked, and the safety is improved.

For example, the number of the preset fingerprint information of the first user may be 3, the number of the preset fingerprint information of the second user may be 2, and so on.
Wherein the first user is a user with an authority level of the electronic device higher than a preset level, the preset level can be a higher authority level allowing most applications accessing the electronic device, for example, an actual holder of the first user electronic device, and the second user can be a user with an authority level lower than that of the first user.
Therefore, when unlocking control is carried out, the first user with the higher authority level can unlock only by inputting a larger amount of fingerprint information, and the user with the higher authority level is given a larger weight, so that the electronic device can be ensured to be used by a legal user, and the safety is further improved.
It should be noted that the steps of the unlocking control method of the present application are not limited to the above steps, the order of the above steps may also be adjusted as needed, and a part of the process in one step may be executed as one step alone. For example, the "determining that the application corresponding to the target application icon is the object to be unlocked" may be performed as a separate step, before step 101, or in parallel with step 101.
