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.
The embodiment of the invention provides an information encryption method, which can be applied to terminal equipment to encrypt fields needing to be encrypted in information stored on the terminal equipment. The information can be information in a short message box, information in instant messaging software, information stored in a memo, contact information in an address book, schedule related information set in a calendar and the like.
According to the method provided by the embodiment of the invention, a user can execute the first input on the target text, determine the target field to be encrypted according to the first operation characteristic of the first input, and encrypt the target field under the condition that the first fingerprint information of the first input is matched with the preset encryption fingerprint information. Therefore, the encrypted target field can be displayed in a ciphertext mode, and even if the terminal equipment is illegally acquired by other people or is illegally unlocked, certain information of the user in the text cannot be acquired after the text is opened, so that the leakage of the user information can be effectively prevented, and the safety of the user information is ensured.
The terminal device can be a mobile phone, a tablet computer, a computer and the like.
Fig. 1 is a flowchart of a method of an information encryption method according to an embodiment of the present invention, where the method shown in fig. 1 at least includes the following steps:
The target text can be short message information, contact information, information in instant messaging software, schedule related information added in a calendar and the like opened by a user on the terminal equipment.
The first input may be a pressing operation, a sliding operation, or the like. Specifically, the user may perform the first input on the target text by using one finger, or may perform the first input on the target text by using a plurality of fingers. The plurality of fingers may be on the same hand or on two hands, and the number of fingers for the user to perform the first input is not limited in the embodiment of the present invention.
Specifically, the first input may be an operation performed on a field in the target text or an operation performed to circle a field around a field in the target text.
For example, the first input may be a press operation performed on a field in the target text, a slide operation performed on a field in the target text, a circle operation performed on a field in the target text, or the like; the above-described operation of circling fields performed around fields in the target text may be an operation of enclosing fields by circles, squares, or the like drawn around some fields in the target text.
In addition, in the embodiment of the present invention, the user performs the first input on the target text, on one hand, to trigger the operation of encrypting the field in the target text, and on the other hand, to inform the terminal device of the target field in the text that needs to be encrypted.
The first fingerprint information is fingerprint information of a finger used by the user to perform the first input on the target text. Wherein the first fingerprint information may include one or more fingerprint information.
The first operation characteristic may be information such as a slide track and a pressing area of the first input.
And step 106, determining a target field to be encrypted according to the first operation characteristic.
The field target field to be encrypted can be fields such as a mobile phone number, a mailbox account, an address, a name, a user related schedule, a password and the like in a target text.
In step 106, the target field to be encrypted may be determined according to the sliding track or the pressing area of the first input.
For ease of understanding, the following description will be given by way of example.
For example, in one embodiment, the first input performed by the user is a sliding operation performed on a field in the target text, the first operation characteristic may include a start position coordinate of the sliding, an end position coordinate of the sliding, and a sliding track, and if the sliding track is a straight line, a field located between the start position coordinate and the end position coordinate of the sliding may be determined as the target field to be encrypted.
For example, in another specific embodiment, the first input is an operation performed to circle a field around a field in the target text, the first operation characteristic may include information such as a shape and a position of the sliding track, and then the field circled by the sliding track of the first input is determined as the target field to be encrypted.
And 108, encrypting the target field under the condition that the first fingerprint information is matched with the preset encrypted fingerprint information, and displaying the encrypted ciphertext.
Specifically, encrypted fingerprint information is prestored in the terminal device, wherein the encrypted fingerprint information is fingerprint information authorized by the user to trigger execution of an encryption operation. The preset encrypted fingerprint information may be single-finger fingerprint information or a combination of multi-finger fingerprint information.
In the embodiment of the invention, after first input first fingerprint information is acquired, whether the first fingerprint information is matched with preset encryption fingerprint information is detected, and if the first fingerprint information is matched with the preset encryption fingerprint information, the first input of a user on a target text is considered as an operation for triggering encryption of a target field. Then step 108 is executed, namely the target field is encrypted, and the encrypted ciphertext is displayed.
In step 108, the target field may be encrypted by using an encryption algorithm in the prior art. For example, a Digital Signature Algorithm (DSA), a symmetric Algorithm (DES), a 3DES Algorithm, or the like may be used.
In specific implementation, if the first fingerprint information is detected to be matched with the preset encryption fingerprint information, a preset encryption algorithm is called, and the target field is encrypted.
After the target field is encrypted, the ciphertext corresponding to the target field is displayed on a display screen, namely, in the target text, the target field is displayed in the encrypted ciphertext mode, so that even if other people illegally acquire the terminal equipment and open the target text, the specific content of some fields in the target text cannot be acquired.
For ease of understanding, the following description will be given by way of example.
For example, in a specific embodiment, an interface diagram of a target text opened by a user is shown in fig. 2(a), if the user needs to encrypt a mobile phone number in the target text, a first input of the user on the target text may be to perform a sliding operation on a mobile phone number field, specifically, the user may slide from the left side of the mobile phone number field to the right side of the mobile phone number field, as shown in fig. 2 (b). The terminal equipment acquires fingerprint information of a user executing sliding operation, a sliding track, a sliding starting point coordinate and a sliding terminal coordinate.
After the information is obtained, the terminal equipment determines a field corresponding to a position where the user executes the sliding operation according to the starting point coordinate of the sliding operation and the terminal coordinate of the sliding operation, and determines the field as a target field to be encrypted; then, whether the fingerprint information of the user executing the sliding operation is matched with the preset encrypted fingerprint information is detected, if so, the determined target field is encrypted by adopting a preset algorithm, and then the encrypted ciphertext is replaced by the target field displayed on the display screen, namely, the final target field (mobile phone number field) is displayed on the display screen in the form of the ciphertext, as shown in fig. 2 (c).
In the embodiment of the invention, the target field to be encrypted can be determined according to the first operation characteristic of the first input of the user on the target text; under the condition that the first input first fingerprint information is matched with preset encryption fingerprint information, encrypting the target field and displaying an encrypted ciphertext; therefore, certain fields in the target text can be encrypted, so that the fields are displayed in a ciphertext mode, the contents of the fields in the text cannot be checked even if the user terminal equipment is illegally stolen or unlocked, and the leakage of user information can be effectively prevented, so that the safety of information on the terminal equipment is ensured, and the safety of the user information is improved; in addition, the user only needs to execute the first input on the target text to realize the encryption of some fields in the target text, and the operation is simple and convenient.
In some embodiments, a plurality of fields that need to be encrypted may exist in a certain target text, and if the field that needs to be encrypted is found in the target text by a user in a manual finding manner, then the first input is executed to encrypt the field, which consumes more time and is more troublesome to operate. Therefore, the information encryption method provided in the embodiment of the present invention may further include, before performing step 102, the following step one and step two;
step one, receiving a second input of a user on a current interface;
under the condition that input information input by the second input is matched with a preset first input condition, extracting and displaying N fields in the target text; wherein, N fields comprise a target field, and N is a positive integer.
It should be noted that, in this embodiment of the present invention, the current interface is an interface for displaying a target text, that is, the second input is an input executed on the interface for displaying the target text, and a position where the second input is executed may be any position on the current interface, may be on the target text on the current interface, or may be on a blank area outside the target text on the current interface.
The second input may be a click operation, a slide operation, or the like; the user may use one finger or multiple fingers when performing the second input, and may use multiple fingers on the same hand or multiple fingers on different hands when performing the second input using multiple fingers, which is not limited in the embodiments of the present invention.
In the embodiment of the present invention, a trigger condition, i.e., a first input condition, corresponding to the field extracting operation may be preset. In this way, when the input information of the second input performed by the user satisfies the first input condition, the operation of extracting the field in the target text is triggered.
The input information of the second input may be third fingerprint information for the user to perform the second input; alternatively, a third operation characteristic of a second input can be performed for the user; still alternatively, the input information of the second input includes third fingerprint information and third operation characteristics of the user performing the second input.
The third operation characteristic may be information such as a sliding track, a pressing time length, a pressing position and the like of the second input.
In the embodiment of the present invention, when the input information of the second input includes only the third fingerprint information of the finger used by the user to perform the second input, in this case, in order to facilitate distinguishing whether the user performs the operation of extracting the field or the operation of encrypting the target field, the third fingerprint information is different fingerprint information from the first fingerprint information. For example, if the first fingerprint information is index finger information of the right hand of the user, the first fingerprint information may be middle finger information of the right hand of the user, etc., and of course, this is merely an exemplary illustration, and the first fingerprint information and the third fingerprint information may also be other fingerprint information; and the first fingerprint information and the third fingerprint information may also be a combination of fingerprints of a plurality of fingers.
It should be noted that, in the embodiment of the present invention, the matching between the input information of the second input and the preset first input condition at least includes the following three cases:
the first and second input third fingerprint information are matched with the first preset fingerprint information;
the second condition, the third operation characteristic of the second input is matched with the first preset operation characteristic;
and in case III, the third fingerprint information of the second input is matched with the first preset fingerprint information, and the third operation characteristic of the second input is matched with the first preset operation characteristic.
In one embodiment, after the user opens the target text on the terminal device, the second input may be performed at any position on the interface where the target text is displayed. The terminal equipment acquires input information of a user executing second input on the interface, wherein the input information of the second input comprises third fingerprint information and third operation characteristics; then, detecting whether the third fingerprint information is matched with the first preset fingerprint information or not and whether the third operation characteristic is matched with the first preset operation characteristic or not; and if so, determining that the input information of the second input is matched with the preset first input condition, and executing the operation of extracting the field in the target text.
In the embodiment of the invention, when the input information of the second input executed on the current interface by the user is matched with the preset first input condition, the operation of extracting and displaying the N fields in the target text is executed. The user only needs to execute second input on the interface for displaying the target text, and can automatically extract N fields which are possibly required to be encrypted in the target text, so that when the user executes encryption operation, the user can directly determine the target fields which are required to be encrypted from the extracted N fields, the user is prevented from searching the target fields which are required to be encrypted in the whole text in a manual mode, and the method is simple, quick and less in time consumption; and the user only needs to execute the second input on the interface to realize the operation, and the operation is simple and convenient.
Specifically, in the second step, the extracting N fields in the target text specifically includes the following steps:
and performing semantic analysis on the target text, and extracting N fields belonging to a predefined type from the target text.
The predefined type is some field types which need to be encrypted and are predefined by a user, and may be, for example, a phone number field type, a website field type, a mailbox field type, and the like. The predefined types may include keyword information, field length information, field type information, etc. of the predefined field types.
In the embodiment of the invention, the semantic analysis is carried out on the target text to judge whether the field which accords with the predefined type exists in the target text, and if so, the field is extracted and displayed.
It should be noted that the N fields extracted from the target text are fields that may need to be encrypted, and the target fields to be encrypted are included in the N fields.
In the embodiment of the invention, the semantic analysis is carried out on the target text, the N fields belonging to the predefined type are extracted from the target text, the fields belonging to the predefined type are searched by adopting a voice analysis method, and the searching accuracy is higher.
For ease of understanding, the following description will be given by way of example.
For example, in one embodiment, the user opens the target text, which still takes the text shown in fig. 2(a) as an example, and the second input performed by the user on the display interface of the target text is a long-press operation, as shown in fig. 3 (a). In this case, the terminal device acquires fingerprint information of a finger used by the user to perform the long press operation, pressing time length information of the long press operation, and the like.
After the information is acquired, the terminal device detects whether the fingerprint information of the long press operation executed by the user is matched with first preset fingerprint information and whether the pressing time length of the long press operation reaches a preset time length, and if yes, the terminal device executes the operation of extracting the field in the target text.
In another embodiment, the second input performed by the user on the display interface of the target text is to perform a sliding operation on the interface in opposite directions using the left and right index fingers, as shown in fig. 3 (b). In this case, the terminal device acquires the fingerprint information of the left index finger, the fingerprint information of the left slide, the fingerprint information of the right index finger, and the fingerprint information of the right slide, with which the user performs the slide operation.
After the information is acquired, the terminal device detects whether the fingerprint information of the left index finger and the fingerprint information of the right index finger of the user performing the sliding operation are matched with first preset fingerprint information (in this case, the first preset fingerprint information also comprises the fingerprint information of two fingers), and whether the track information sliding leftwards and the track information sliding rightwards are matched with first preset operation characteristics (the first preset operation characteristics comprise two pieces of track information); and if so, executing the operation of extracting the field in the target text.
Regardless of whether the user performs the long press operation as shown in fig. 3(a) or the slide operation as shown in fig. 3(b) on the interface displaying the target text, in the case where the input information of the second input satisfies the preset first input condition, the field in the target text needs to be extracted and displayed.
Specifically, the extracted field may be displayed in a blank area of the interface where the target text is currently displayed, as shown in fig. 3(c), or a blank interface may be newly created, and then the extracted field is displayed on the newly created blank interface, as shown in fig. 3 (d).
For the case shown in fig. 3(c), an interface diagram in which the user performs the first input on the target text is shown in fig. 3 (e). For the case shown in fig. 3(d), an interface diagram in which the user performs the first input on the target text is shown in fig. 3 (f). In both the cases shown in fig. 3(d) and fig. 3(f), after the user performs the first input and encrypts the target field to be encrypted, the interface of the displayed information is the same as the interface shown in fig. 2(c), and details thereof are not repeated here.
In addition, in the embodiment of the present invention, after the target field to be encrypted is encrypted, the target field to be encrypted is displayed in the target text in the form of the ciphertext, and when the target text is opened next time by the user, the field encrypted in the target text is still displayed in the form of the ciphertext. In order to facilitate the user to view the field corresponding to the ciphertext, in the embodiment of the present invention, after the step 108 is executed, the method provided in the embodiment of the present invention further includes the following step (1) and step (2);
step (1), receiving a third input of the user on the ciphertext
And (2) decrypting the ciphertext and displaying the decrypted target field under the condition that the input information of the third input meets a preset second input condition.
The third input may be a pressing operation, a sliding operation, or the like.
The input information of the third input may be second fingerprint information; alternatively, a second operating characteristic for a third input may also be present; or the input information of the third input can also be second fingerprint information and second operating characteristics.
Specifically, the third input information satisfies a preset second input condition, which may include at least the following cases:
the first and third input second fingerprint information is matched with preset decryption fingerprint information;
the second operation characteristics of the second input and the third input are matched with the preset characteristics;
and the third and third input second fingerprint information is matched with the preset decryption fingerprint information, and the third input second operation characteristic preset characteristics are matched.
In the embodiment of the invention, when a user wants to check the field corresponding to a certain ciphertext in the target text, only the third input is executed on the ciphertext, the operation is simple and convenient, and the user can check the field corresponding to the ciphertext at any time conveniently.
In a specific embodiment, the input information of the third input mentioned in the above step (2) includes second fingerprint information and a second operation characteristic;
correspondingly, in this case, in the step (2), when the third input information meets a preset second input condition, decrypting the ciphertext and displaying a decrypted target field specifically includes:
acquiring third input second fingerprint information and second operation characteristics; and under the condition that the second fingerprint information is matched with the preset decryption fingerprint information and the second operation characteristic is the preset characteristic, decrypting the ciphertext and displaying the decrypted target field.
Specifically, the second fingerprint information is fingerprint information of a finger used by the user to perform a third input; the second operation characteristic may be a slide track of the third input, pressing duration information, or the like.
In the embodiment of the present invention, when the ciphertext is decrypted, it is required that the third input second fingerprint information is matched with the preset decryption fingerprint information, and when the second operation characteristic of the third input is the preset operation characteristic, it is determined that the third input executed by the user on the ciphertext is the operation for triggering decryption of the ciphertext. Therefore, the situation that the user mistakenly touches a certain section of ciphertext on the display screen to cause the terminal equipment to mistakenly decrypt the ciphertext can be reduced, and the occurrence of misoperation is reduced, so that the electric quantity consumed by the terminal equipment due to the execution of misoperation is reduced, and the use experience of the user is also improved.
For ease of understanding, the following description will be given by way of example.
Taking the display interface of the encrypted ciphertext shown in fig. 2(c) as an example, when the user needs to view the phone number field in the target text, the third input performed by the user may be a sliding operation performed on the ciphertext corresponding to the phone number field, specifically, the third input may be a sliding operation performed from the right side to the left side of the ciphertext corresponding to the phone number field, which indicates that the ciphertext corresponding to the entire phone number field is selected, so that the terminal device knows the ciphertext that needs to be decrypted, as shown in fig. 4, the terminal device obtains fingerprint information of a finger used by the user when performing the sliding operation, a sliding track, start position coordinates of the sliding operation, and end position coordinates of the sliding operation.
After the information is acquired, the terminal device detects whether the fingerprint information is matched with preset decryption fingerprint information or not and detects whether the sliding track is matched with a preset track or not, and if yes, the operation executed by the user is considered to be an operation for checking a field corresponding to the ciphertext. At this time, the terminal device judges the ciphertext corresponding to the sliding operation executed by the user according to the initial position coordinate of the sliding operation and the terminal position coordinate of the sliding operation, then executes decryption operation on the ciphertext, so as to obtain the field corresponding to the ciphertext, and displays the field corresponding to the ciphertext.
Fig. 5 is a second flowchart of an information encryption method according to an embodiment of the present invention, where the method shown in fig. 5 at least includes the following steps:
In the embodiment of the invention, when a user needs to encrypt a certain text on the terminal device, the text needs to be opened, and the text is called as a target text.
The target text can be any text information on the terminal device, such as short message information, contact information, information in instant messaging software, schedule related information added in a calendar, and the like.
The second input may be a second input executed on the target text, or may be a second input executed on a blank area of the current interface other than the target text. The second input may be a long press operation, a slide operation, or the like.
The third operation characteristic may be information such as a sliding track of the second input, a pressing time length, and the like.
Specifically, in step 508, N fields belonging to the predefined type may be extracted from the target text by performing semantic analysis on the target text.
The extracted N fields may be displayed in a blank area on an interface where the target text is currently displayed, or the N fields may be displayed on a newly created blank interface.
The first input may be a sliding operation, a pressing operation, or the like.
The first operation characteristic may be information such as a sliding track of the user on the field, a pressing position, and the like.
Step 516, detecting whether the first fingerprint information matches the preset encrypted fingerprint information, if yes, performing step 518, otherwise, performing step 520.
And 518, encrypting the target field and displaying the encrypted ciphertext.
Specifically, when the target field is encrypted, the encryption can be implemented by calling a preset encryption algorithm. The preset encryption algorithm may be a digital signature algorithm, a symmetric algorithm, etc.
The user can be prompted in a text or voice mode that the current operation is wrong and the execution operation is required to be performed again.
The implementation process of each step in the embodiment corresponding to fig. 5 is the same as the specific implementation process of each step in the embodiment corresponding to fig. 1 to 4, and therefore, the specific implementation process of each step may refer to the embodiment corresponding to fig. 1 to 4, and is not described herein again.
According to the information encryption method provided by the embodiment of the invention, the first fingerprint information and the first operation characteristic which are input by a user in a first mode on a target text are obtained, then a target field to be encrypted is determined according to the first operation characteristic, the target field is encrypted under the condition that the first fingerprint information is matched with the preset encryption fingerprint information, and an encrypted ciphertext is displayed; certain fields in the target text can be encrypted, so that the encrypted fields in the target text are displayed on a display screen in a ciphertext mode, even if the terminal equipment of a user is illegally stolen or unlocked, the safety of information on the terminal equipment can be still ensured, the leakage of user information can be effectively prevented, and the safety of the user information is improved; in addition, the field to be encrypted in the information is encrypted in a mode that the user executes operation on the target text, and the operation is simple and convenient.
