Description

Unlocking method and terminal equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to an unlocking method and terminal equipment.

Background

Encryption of terminal devices has become very common due to the requirements of terminal device security and privacy. Such as mobile payment, handset unlock, application encryption, profile encryption, etc. The encryption and decryption techniques used more widely currently are passwords, fingerprints, faces, irises, etc. Moreover, along with the development of screen integration technology, more and more terminal equipment's screen is integrated with the fingerprint inductor in, according to the coverage of fingerprint inductor, can divide into two kinds: the method comprises the following steps that (1) fingerprint under a screen is realized, namely a fingerprint sensor is attached to the lower part of the screen, and fingerprint image information is received in a light wave or ultrasonic wave mode; full-screen fingerprints are that fingerprint sensors are directly integrated on screen glass printed circuits, namely, fingerprint image information can be received at any position or partial position of the whole screen in light waves, ultrasonic waves, capacitors and other modes.

However, among the encryption and decryption techniques that are currently in widespread use, there are various disadvantages. Such as password encryption, the user is easily snooped by other people when inputting the password, and the password is leaked. While the security of fingerprint encryption and decryption is slightly higher, the security hole of the copied fingerprint of a person still exists. Face recognition may not be able to distinguish twins and result in being broken by siblings. The requirement of iris recognition on an iris image acquisition device is high, the acquisition process is slow, and the high cost and low use experience are not suitable for consumer products. In summary, although the existing encryption methods can improve the security and privacy of the terminal device to some extent, they are still easy to be cracked or slow in response and too high in cost.

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 an invasive task, are within the scope of the present invention.

Referring to fig. 1, a flowchart of an unlocking method according to an embodiment of the present invention is shown, and is applied to a terminal device, where the method specifically includes the following steps:

step 110, a first touch input of N fingers of a user is received.

In the embodiment of the invention, under the condition of not influencing unlocking efficiency and cost, in order to further improve the safety and privacy of the terminal equipment, a safer and more efficient encryption method is obtained by combining the fingerprint and a password sequence defined by a certain rule in the terminal equipment comprising the fingerprint sensor, so that the encryption safety is improved, and the possibility that the password of the terminal equipment is cracked by others is reduced to the minimum.

In practical application, the password of the terminal device can be a combination of characters such as numbers, letters, symbols and the like, and the association relationship between the fingerprint and the characters can be preset in the embodiment of the invention, so that the characters corresponding to the fingerprint can be input by inputting the fingerprint. According to the preset association relationship between the fingerprint and the characters, the obtained target fingerprint information can be converted into a first character sequence, and the input sequence of each target fingerprint information can be converted into the sequence of each character in the first character sequence.

First, a first touch input of N fingers of a user needs to be received. Moreover, as mentioned above, the fingerprint sensor of the terminal device may include both of the off-screen fingerprint and the full-screen fingerprint, and then the corresponding terminal device may also receive the first touch input of the N fingers of the user through the off-screen fingerprint identifier or the full-screen fingerprint identifier. Of course, in the embodiment of the present invention, the first touch input of the N fingers of the user may be received by any other available method or device, which is not limited to the embodiment of the present invention. Wherein the value of N is a positive integer. In addition, in the embodiment of the present invention, the first touch input and the subsequent second touch input may be input by, but not limited to, pressing or touching, and the like, and may be preset according to requirements, which is not limited to the embodiment of the present invention.

The terminal device may receive the first touch input of the N fingers of the user through the fingerprint sensor, and may also receive the first touch input of the N fingers of the user through any other available device, which is not limited in the embodiment of the present invention. For example, if the fingerprint sensor of the terminal device is a full-screen fingerprint sensor, the user may press or touch the screen with a finger to input the first touch input. Furthermore, if the set association relationship between the fingerprint and the character is that each half of the fingerprint corresponds to one character, then the input of the fingerprint information can be performed by alternately tilting the finger and pressing or touching the screen.

For example, the left thumb presses screen- > right middle finger presses screen- > right index finger presses screen … …

The specific user can also put related fingers on the screen, and then characters corresponding to each finger can be respectively displayed at positions corresponding to two sides above each finger in a display interface of the terminal equipment for prompting the user to input the corresponding characters, and at the moment, the user can input fingerprint information only by sequentially inclining the corresponding fingers.

Step 120, acquiring N pieces of target fingerprint information corresponding to first touch inputs of the N fingers; wherein each target fingerprint information is all or part of a fingerprint of a finger.

After receiving the first touch input of the N fingers of the user, N pieces of target fingerprint information of the first touch input of the N fingers may be further obtained, where each piece of target fingerprint information is a whole or partial fingerprint of one finger. If the user inputs the first touch input through the fingerprint recognizer of the terminal device, the target fingerprint information corresponding to each first touch input can be directly obtained based on the recognition of the fingerprint recognizer. For example, if a first touch input of a user through any finger is received, a fingerprint of the finger when the corresponding first touch input is input may be acquired, and if the input is a left-side finger touch input, the target fingerprint information that may be acquired may be a left-side fingerprint of the corresponding finger.

In the embodiment of the invention, according to the pressing habit that the user can input the fingerprint, the user can perform touch operation by using the whole fingerprint or part of the fingerprint, so that each piece of target fingerprint information can be set to be the whole or part of the fingerprint of one finger. The corresponding relationship between the target fingerprint information and the finger fingerprint may be preset according to the requirement, and the embodiment of the present invention is not limited. For example, each target fingerprint information may be set to be a half fingerprint of one finger, and each target fingerprint information may be any one of the top half fingerprint, the bottom half fingerprint, the left half fingerprint, or the right half fingerprint of any one finger.

Step 130, determining a first character sequence associated with the N target fingerprint information; wherein a character is associated with all or part of a fingerprint of a finger.

In the embodiment of the present invention, in order to confirm the corresponding character sequence based on the target fingerprint information, it may be preset that one character is associated with all or part of a fingerprint of one finger. And further, a first character sequence associated with the acquired N pieces of target fingerprint information can be determined based on the association relationship between the set characters and the fingerprints. The association relationship between the characters and the fingerprints can be preset according to requirements, and the embodiment of the invention is not limited.

In order to convert the fingerprint information into the first character sequence, it is necessary to set an association relationship between the fingerprint and the character in the terminal device in advance, and store a fingerprint pattern in the association relationship between the fingerprint and the character in the terminal device. The specific method can be implemented by setting each half fingerprint and/or the corresponding symbol of each fingerprint in a specific setting interface in advance by a user, and storing the related fingerprint patterns. Taking fig. 2 as an example, the numbers 0-9 correspond to each half of the fingerprints in the 5 fingers of the right hand. The user can respectively input each half fingerprint pattern in the terminal equipment in advance, and set the character corresponding to each half fingerprint pattern, and then set the association relation between the fingerprint and the character.

For example, a half fingerprint in which one character is associated with one finger may be set in advance. Moreover, the half fingerprint may be at least one of an upper half fingerprint, a lower half fingerprint, a left half fingerprint, and a right half fingerprint.

For example, when the association relationship between the set characters is that each half of the fingerprint is associated with one character, the half of the fingerprint may be a left half of the fingerprint and a right half of the fingerprint. Also, the characters at this time are ten numerals 0 to 9. Then, as shown in fig. 2, the right half of the thumb corresponds to the number 1, the left half of the thumb corresponds to the number 2, the right half of the index finger corresponds to the number 3, the left half of the index finger corresponds to the number 4, and so on. The corresponding relation can be changed by user setting, for example, the left half fingerprint of the thumb corresponds to the number 0, the right half fingerprint corresponds to the number 9, the left half fingerprint of the index finger corresponds to the number 8, the right half fingerprint corresponds to the number 7, and so on. It is also possible to shuffle the number order, in any case having one number for each half of the fingerprint, for example 10 numbers for each of the left and right sides of the fingerprint of 5 fingers in the right hand as shown in fig. 2. Of course, in the embodiment of the present invention, half fingerprints corresponding to 10 numbers may be selected from the fingerprints of the left hand and the fingerprint of the right hand, which is not limited in the embodiment of the present invention. However, it is obvious that if 10 numbers are respectively corresponding to the fingerprints of the right hand, the use habit of the user is better met, and the user can conveniently input the fingerprints.

When the set fingerprint-to-character relationship associates a character with each fingerprint, the characters at this time are also ten numbers 0 to 9. Then the method of one digit per finger fingerprint can be directly adopted at this time, and ten digits of two hands are respectively in one-to-one correspondence with ten digits, as shown in fig. 3A and 3B. The association relation between each finger fingerprint and each character can be set by the user at will, and the user can set in the corresponding setting interface in advance. For example, the fingerprint of the left thumb corresponds to the number 1, the fingerprint of the left index finger corresponds to the number 2, the fingerprint of the left middle finger corresponds to the number 3, and so on; or any of the left thumb fingerprint corresponding to the number 5, the left index finger fingerprint corresponding to the number 3, etc.

Alternatively, the set fingerprint to character relationship is one character for each half of the fingerprint, and one character for each fingerprint. Then this time 0 to 9 ten digits for the aforementioned character. For example, a right thumb and a left half of a right thumb may correspond to the number 1, a right thumb and a left half of a right thumb may correspond to the number 2, a right index finger and a right half of a right finger may correspond to the number 3, a right index finger and a left half of a right finger may correspond to the number 4, a right middle finger and a right half of a right finger may correspond to the number 5, a right middle finger and a left half of a right finger may correspond to the number 6, a right ring finger and a right finger may correspond to the number 7, a left thumb and a left finger may correspond to the number 8, a left index finger and a left finger may correspond to the number 9. The specific correspondence between the finger print and the character may be set arbitrarily by the user, and the embodiment of the present invention is not limited thereto.

After the association relationship between the characters and the fingerprints is set, a first character sequence associated with the acquired N pieces of target fingerprint information can be determined. Specifically, the N pieces of fingerprint information may be converted into characters according to a set association relationship between the characters and the fingerprints, and the converted characters are arranged in order from beginning to end according to the input of each piece of target fingerprint information, so as to obtain a first character sequence.

Then, when the user inputs the fingerprint information, the user can perform a first touch input by touching or pressing the fingerprint sensor with a finger. Also, in the embodiment of the present invention, the conversion accuracy may be set when converting the target fingerprint information into characters. For example, according to the association relationship between the fingerprint and the character, the obtained target fingerprint information may be converted into a character corresponding to a fingerprint in the association relationship between the fingerprint and the character, where the similarity of the fingerprint corresponding to the target fingerprint information is greater than a preset similarity, where the preset similarity may be preset according to a requirement, and the embodiment of the present invention is not limited thereto. Or if the set association relationship between the fingerprint and the character includes a character corresponding to a half fingerprint, but the whole fingerprint corresponding to the half fingerprint is not set, then if the whole fingerprint corresponding to the half fingerprint input by the user is received, the whole fingerprint cannot be converted into the character, the character position corresponding to the whole fingerprint in the corresponding first character sequence can be marked as a space or a preset special symbol, that is, the first character sequence input by the user cannot be matched with the preset character sequence at this time. Of course, if the set association relationship between the fingerprint and the character includes a character corresponding to a half fingerprint, and the entire fingerprint corresponding to the half fingerprint is not set, or the other half fingerprint complementary to the half fingerprint is not set, it may also be set that, when the entire fingerprint corresponding to the half fingerprint input by the user is received, the entire fingerprint is converted into the character corresponding to the half fingerprint. The specific configuration may be set according to the requirement, and the embodiment of the present invention is not limited thereto.

The embodiment obtains a more secure encryption mode by creatively combining the fingerprint decryption and the password decryption. To break the password, the finger fingerprints of the user must be copied, and the user can break the password only by knowing the input sequence of the fingers. The encryption safety is greatly improved, and the decryption by others is prevented.

And 140, unlocking the terminal equipment under the condition that the first character sequence is matched with a preset character sequence.

After the first character sequence associated with the N pieces of target fingerprint information is determined, it may be further determined whether the first character sequence matches a preset character sequence, and if the first character sequence matches the preset character sequence, the terminal device may be unlocked. The preset character sequence can be understood as a preset character sequence which can unlock the terminal device, and the preset character sequence can be preset according to requirements, and the embodiment of the invention is not limited.

In the embodiment of the present invention, after the first character sequence is determined, it may be determined whether the first character sequence matches a preset character sequence, or after each piece of target fingerprint information is acquired, the target fingerprint information is converted into a character, and it is determined whether the character matches a character at a corresponding position in the preset character sequence, which may be preset according to a requirement, and the embodiment of the present invention is not limited thereto.

Moreover, in practical applications, the terminal device may be encrypted, and file data, an application program, a payment operation, and the like in the terminal device may also be encrypted, so that the unlocking method in the embodiment of the present invention may also be applied to the above encrypted target, and therefore, in the embodiment of the present invention, a first touch input of a user for a target unlocking task may be received, where the target unlocking task may include, but is not limited to, unlocking the terminal device, unlocking the file data, unlocking the application program, unlocking the payment operation, and the like. Further acquiring N pieces of target fingerprint information corresponding to first touch input of the N fingers; determining a first sequence of characters associated with the N pieces of target fingerprint information; and executing the target unlocking task under the condition that the first character sequence is matched with a preset character sequence. In addition, the association relationship between the fingerprint and the character referred to at this time corresponds to the target unlocking task. In the embodiment of the invention, the association relationship between the fingerprint and the character can be different or the same for different terminal devices; the association relationship between the fingerprint and the character can be different or the same for different unlocking tasks in the same terminal equipment. The specific configuration of the present invention can be preset according to the requirement, and the embodiment of the present invention is not limited thereto.

For example, if the target unlocking task is to unlock the terminal device, if the currently input first character sequence matches with a preset character sequence, the terminal device may be controlled to be unlocked; if the target unlocking task is to unlock the current payment operation in the terminal equipment, the terminal equipment can be controlled to complete the corresponding payment operation at the moment; and so on.

In addition, in the embodiment of the present invention, in order to determine the first character sequence associated with N pieces of target fingerprint information, it may be determined whether the target fingerprint information matches a fingerprint pattern pre-stored in the terminal device, and if the target fingerprint information matches the fingerprint pattern pre-stored in the terminal device, a character corresponding to the target fingerprint information is determined according to a preset association relationship between a fingerprint and a character. And then arranging corresponding characters according to the input sequence of the target fingerprint information to obtain a first character sequence associated with the N pieces of target fingerprint information.

As described above, in the embodiment of the present invention, in order to conveniently convert the target fingerprint information into the first character sequence, a fingerprint pattern may be prestored in the terminal device, and after the target fingerprint information is acquired, before the conversion is performed, it is first required to ensure that the target fingerprint information matches the fingerprint pattern prestored in the terminal device. It is therefore necessary to determine whether the target fingerprint information matches a fingerprint pattern prestored in the terminal device. Specifically, the target fingerprint information can be compared with a fingerprint pattern prestored in the terminal device, and if the similarity between the target fingerprint information and a certain fingerprint pattern prestored in the terminal device meets a preset similarity condition, the target fingerprint information can be confirmed to be matched with the fingerprint pattern prestored in the terminal device.

Moreover, in the embodiment of the present invention, it may be determined whether a target fingerprint pattern matches a fingerprint pattern pre-stored in the terminal device every time a target fingerprint pattern is acquired, and if one of the target fingerprint patterns acquired for one-time unlocking task does not match the fingerprint pattern pre-stored in the terminal device, it may be determined that the first touch input by the user is incorrect, at this time, a password error may be prompted, and the terminal device may be controlled to return to the password input interface to re-receive the first touch input by the user. Or after the user inputs all first touch inputs for the current target unlocking task, judging whether corresponding target fingerprint information is matched with a fingerprint pattern prestored in the terminal equipment, if at least one target fingerprint information is not matched with the fingerprint pattern prestored in the terminal equipment, confirming that the first touch input by the user is wrong, prompting a password error, and controlling the terminal equipment to return to a password input interface so as to re-receive the first touch input by the user for the target unlocking task.

If the target fingerprint information is matched with a fingerprint pattern prestored in the terminal equipment, a first character sequence corresponding to the target fingerprint information can be determined according to a preset association relationship between the fingerprint and the characters.

For example, it is assumed that the set association relationship between fingerprints and characters is a character corresponding to each half of a fingerprint, and the characters at this time are ten numbers from 0 to 9, and the preset association relationship between characters and fingerprints is shown in fig. 2. If the target fingerprint information input by the user aiming at the current target unlocking task is in the following sequence: and the right side of the thumb finger of the right hand- > the right side of the index finger of the right hand- > the left side of the thumb of the right hand- > the left side of the index finger of the right hand, the characters corresponding to the target fingerprint information can be determined to be 1, 3, 2 and 4 respectively in sequence.

As mentioned above, the entry order of the target fingerprint information corresponds to the front-back order of the characters in the first character sequence, so after the characters corresponding to the target fingerprint information are determined, the characters corresponding to the corresponding target fingerprint information may be arranged according to the entry order of the first trigger input corresponding to the target fingerprint information, so as to obtain the first character sequence corresponding to the target fingerprint information.

For example, for each fingerprint trigger input corresponding to the aforementioned target fingerprint information, the entry sequence is as follows: the right side of the right thumb- > the right side of the right index finger- > the left side of the right thumb- > the left side of the right index finger, and the characters corresponding to the target fingerprint information are 1, 3, 2 and 4 respectively. Then the first character sequence 1324 corresponding to the target fingerprint information may be obtained at this time.

In addition, in the embodiment of the present invention, in order to determine whether the first character sequence matches the preset character sequence, whether each character in the first character sequence matches the preset character sequence may be sequentially determined according to a receiving sequence of the first touch input corresponding to each character in the first character sequence. And if any character in the first character sequence does not match with the preset character sequence, confirming that the first character sequence does not match with the preset character sequence. And if the characters in the first character sequence are matched with the preset character sequence, confirming that the first character sequence is matched with the preset character sequence.

For example, if the predetermined character sequence is 1234. Then, when sequentially judging whether each character in the first character sequence matches the preset character sequence according to the entry sequence of each character in the first character sequence corresponding to the first touch input, it may be respectively judged whether a first character in the first character sequence matches a first character in the preset character sequence, whether a second character in the first character sequence matches a second character in the preset character sequence, whether a third character in the first character sequence matches a third character in the preset character sequence, and whether a fourth character in the first character sequence matches a fourth character in the preset character sequence.

In the embodiment of the invention, when the user inputs the target fingerprint information aiming at the target unlocking task, when a target fingerprint pattern is obtained, whether the currently obtained target fingerprint information is matched with the fingerprint pattern prestored in the terminal equipment or not can be judged. If the currently acquired target fingerprint information is matched with a fingerprint pattern prestored in the terminal equipment, determining characters corresponding to the currently acquired target fingerprint information according to the association relationship between the fingerprint corresponding to the target unlocking task and the characters, and further judging whether the characters corresponding to the currently acquired target fingerprint information are matched with a preset character sequence corresponding to the target unlocking task according to the input sequence of the currently acquired target fingerprint information.

For the first character sequence 1324 and the preset character sequence 1234, in the embodiment of the present invention, it can be obtained that the third character of the first character sequence does not match the third character of the preset character sequence, and at this time, it can be confirmed that the current first character sequence does not match the preset character sequence, and it is not necessary to continuously determine the subsequent characters in the first character sequence.

And if the fingerprint information input by the user is: right thumb right- > right thumb left- > right index finger right- > right index finger left, and the first character sequence obtained is 1234. The preset password information is still 1234 at this time. Then, it is determined that all the characters in the first character sequence match the preset character sequence, and at this time, it is determined that the first character sequence matches the preset character sequence.

And if the first character sequence is not matched with a preset character sequence, prompting that the password is wrong, and controlling the terminal equipment to return to a password input interface so as to acquire target fingerprint information input by the user aiming at the target unlocking task.

The way of prompting the password error can be preset according to the requirement, and the embodiment of the invention is not limited. The specific forms such as the appearance of the password input interface can also be preset according to the needs, and the password input interfaces for different unlocking tasks can be different or completely different, and the embodiment of the invention is not limited. After the terminal device returns to the password input interface, the terminal device user can re-input the fingerprint information for the target unlocking task.

In the embodiment of the invention, a first touch input of N fingers of a user is received; acquiring N pieces of target fingerprint information corresponding to first touch input of the N fingers; determining a first sequence of characters associated with the N target fingerprint information; unlocking the terminal equipment under the condition that the first character sequence is matched with a preset character sequence; each target fingerprint information is all or part of fingerprint of one finger, and one character is associated with all or part of fingerprint of one finger. The encryption security of the terminal equipment can be improved without influencing the unlocking efficiency and the encryption cost.

Referring to fig. 4, a flowchart of an unlocking method according to another embodiment of the present invention is shown, which may specifically include the following steps:

step 210, receiving second touch input of the N fingers of the user; wherein one finger includes at least one target fingerprint information.

In practical application, a user may forget a specific association relationship in a use process after setting the association relationship between the fingerprint and the character, which may cause that the user may hardly input a correct character sequence to unlock the electronic device, and affect the use experience of the user. Therefore, in the embodiment of the present invention, in order to avoid the above situation, a reminding mechanism may be additionally provided to display the set characters associated with each fingerprint to the user.

Specifically, second touch input of N fingers of the user can be set to be received so as to trigger reminding of association relation between fingerprints and characters; moreover, in order to avoid malicious acquisition of a preset association relationship between the fingerprint and the character by other users, and because the target fingerprint information may be all or part of the fingerprint of one finger, the one finger at this time may include at least one piece of target fingerprint information. The value of N may also be set by the user, and the embodiment of the present invention is not limited thereto. Moreover, the second touch input of the N fingers may be simultaneous input or may not require simultaneous input, which is not limited in the embodiment of the present invention. Moreover, if the second touch inputs of the N fingers are not input simultaneously, it may be further set that if the time difference between the next touch input and the previous touch input exceeds a preset time period, the next touch input and the previous touch input are not determined as the same batch of second touch inputs, where the preset time period may be preset according to requirements, and the embodiment of the present invention is not limited thereto.

Step 220, acquiring N touch areas corresponding to the second touch input.

In the embodiment of the present invention, in order to facilitate a user to intuitively know characters corresponding to a fingerprint in each finger, characters corresponding to a corresponding fingerprint may be displayed in a target display area corresponding to a touch area corresponding to a second touch input corresponding to each fingerprint, and then after receiving second touch inputs of N fingers of the user, N touch areas corresponding to the second touch inputs may be further obtained.

For example, assume that a second touch input of five fingers of the user is received, respectively a thumb, an index finger, a middle finger, a ring finger, and a pinky finger of the right hand. Then, at this time, touch areas corresponding to the second touch inputs of the five fingers may be obtained, and at this time, five touch areas may be obtained correspondingly.

Step 230, displaying characters associated with all target fingerprint information contained in the finger corresponding to each touch area in the target display area corresponding to each touch area respectively.

In the embodiment of the present invention, the target display areas corresponding to different touch areas may be set in advance according to requirements, and the embodiment of the present invention is not limited thereto. For example, the target display area corresponding to each touch area may be set to be the position of the corresponding touch area, and so on. Then, after the touch area corresponding to each second touch input is obtained, characters associated with all target fingerprint information included in the finger corresponding to the corresponding touch area may be further displayed in the target display area corresponding to each touch area.

For example, for the received second touch inputs of five fingers of the user, the obtained corresponding five touch areas are obtained. Assume touch area 1, touch area 2, touch area 3, touch area 4, and touch area 5, respectively. Moreover, if the touch area 1 corresponds to the second touch input of the thumb of the right hand, the touch area 2 corresponds to the second touch input of the index finger of the right hand, the touch area 3 corresponds to the second touch input of the middle finger of the right hand, the touch area 4 corresponds to the second touch input of the ring finger of the right hand, and the touch area 5 corresponds to the second touch input of the little finger of the right hand, it is assumed that the target display area corresponding to each touch area is set as the position of the corresponding touch area. Then, at this time, characters associated with all target fingerprint information included in the right thumb may be displayed at the position of the touch area 1, characters associated with all target fingerprint information included in the index finger of the right hand may be displayed at the position of the touch area 2, characters associated with all target fingerprint information included in the middle finger of the right hand may be displayed at the position of the touch area 3, characters associated with all target fingerprint information included in the ring finger of the right hand may be displayed at the position of the touch area 4, and characters associated with all target fingerprint information included in the little thumb of the right hand may be displayed at the position of the touch area 5. Further, if the preset fingerprint of the right thumb of the user is target fingerprint information, and the character associated with the fingerprint information is 1; the fingerprint of the left half of the index finger of the right hand of the user is target fingerprint information, and the character associated with the fingerprint information is 2; the fingerprint of the right half of the index finger of the right hand of the user is target fingerprint information, and the character associated with the fingerprint information is 3. Then the character displayed at the location of touch area 1 is 1 and the characters displayed at the location of touch area 2 are 2 and 3.

Moreover, for the case that one finger includes a plurality of target fingerprint information, when displaying the corresponding target display area to respectively display the characters associated with all the target fingerprint information included in the corresponding finger, the target display area can be further divided to respectively display the characters associated with the plurality of target fingerprint information included in the corresponding finger, and the corresponding relationship between the characters and the finger fingerprint corresponding to the associated target fingerprint information can be simultaneously prompted to the user.

For example,

characters

2 and 3 may be displayed in the position of the touch area 2 from left to right to prompt the user that the

characters

2 and 3 correspond to the left half fingerprint of the index finger and the right half fingerprint of the index finger, respectively.

In step 240, a first touch input of N fingers of the user is received.

Optionally, in an embodiment of the present invention, the first touch input is a press input.

Step 250, acquiring N pieces of target fingerprint information corresponding to first touch input of the N fingers; wherein one target fingerprint information is associated with one target character.

In step 260, N target characters associated with N target fingerprint information are determined.

After obtaining N pieces of target fingerprint information corresponding to the first touch input of the N fingers, a target character associated with each piece of target fingerprint information may be determined based on a preset association relationship between a fingerprint and a character.

For example, if the acquired 3 pieces of target fingerprint information corresponding to the first touch input of the 3 fingers are respectively a right half fingerprint of a right index finger, a left half fingerprint of a middle finger of the right hand, and a right half fingerprint of a thumb of the right hand, and the preset association relationship between the fingerprints and the characters is shown in fig. 2, it may be determined that the target characters associated with the 3 pieces of target fingerprint information are sequentially respectively 3, 6, and 1.

Step 270, acquiring a touch sequence of the first touch input of the N fingers.

After determining N target characters associated with the N target fingerprint information and the touch order of the first touch inputs of the N fingers, a first character sequence may be determined based on the N target characters and the touch order of the respective first touch inputs.

For example, for 3 pieces of target fingerprint information corresponding to the aforementioned first touch input with 3 fingers, which are respectively a right half fingerprint of an index finger of a right hand, a left half fingerprint of a middle finger of the right hand, and a right half fingerprint of a thumb of the right hand, it is determined that target characters associated with the 3 pieces of target fingerprint information are sequentially respectively 3, 6, and 1. If the touch sequence of the first touch input of the three fingers is as follows in sequence: the first touch input of the right half fingerprint of the right index finger, the first touch input of the left half fingerprint of the right middle finger, and the first touch input of the right half fingerprint of the right thumb, then it may be determined that the first character sequence is: 361.

In the embodiment of the present invention, each piece of target fingerprint information may be set to be a partial fingerprint of one finger, for example, a half fingerprint of one finger, and the like. The present invention can be specifically configured by a user according to a requirement, and the embodiment of the present invention is not limited.
