In order to illustrate the technical scheme of the application, the following description is made by specific examples.
Fig. 1 shows a schematic implementation flow chart of a data encryption method according to an embodiment of the present application, where the method may be applied to a terminal device.

Step S103, ECC encryption is conducted on the first half part of data based on the fingerprint information, a first private key is generated, and first segment encrypted data is obtained.
Wherein the first half data is the first half data of the original data.
It will be appreciated that the terminal device may divide the original data equally into two parts, i.e. the original data may be divided into a first half of data and a second half of data.
It should be appreciated that ECC (Ellipse Curve Ctyptography) is a public key encryption algorithm based on elliptic curve math. ECC is a cryptosystem established on the discrete logarithm problem based on an elliptic curve, a point G on the elliptic curve is given, an integer K is selected, and K=kG is easy to solve; conversely, given two points K and G on the elliptic curve, if k=kg, it is a difficult problem to find an integer K. ECC is based on this mathematical problem, which is called the elliptic curve discrete logarithm problem. Wherein the point K on the elliptic curve is the public key and the integer K is the private key.
In the embodiment of the application, the terminal equipment can perform ECC encryption on the first half part of data by utilizing the fingerprint information so as to obtain first segment encrypted data, and meanwhile, a first private key is generated in the ECC encryption process.
Step S104, ECC encryption is conducted on the second half part of data based on eyeball information, a second private key is generated, and second segment encrypted data is obtained.
The second half data is the second half data of the original data.
In the embodiment of the application, the terminal device can perform ECC encryption on the second half part of data by utilizing eyeball information so as to obtain second segment encrypted data, and a second private key is generated in the ECC encryption process.
Step S105, combining the first segment encrypted data, the second segment encrypted data, the first private key and the second private key to obtain encrypted data.
In the embodiment of the application, after the first segmented encryption data, the second segmented encryption data, the first private key and the second private key are obtained, the terminal equipment can combine the first segmented encryption data and the second segmented encryption data, and the first private key and the second private key are respectively inserted into the combined data, so that the encryption data is finally obtained.
Compared with the prior art, the embodiment of the application has the beneficial effects that: the embodiment of the application can acquire the original data to be encrypted, the fingerprint information and the eyeball information, perform ECC encryption on the first half part of data based on the fingerprint information, generate a first private key and acquire first segment encrypted data, perform ECC encryption on the second half part of data based on the eyeball information, generate a second private key and acquire second segment encrypted data, and acquire encrypted data by combining the first segment encrypted data, the second segment encrypted data, the first private key and the second private key. The embodiment of the application utilizes fingerprint information, eyeball information and ECC encryption technology to encrypt the original data in a combined way, thereby improving the confidentiality of the encrypted data and ensuring that the encrypted data is not easy to crack.
In some embodiments of the present application, the above-mentioned combination of the first segmented encryption data, the second segmented encryption data, the first private key and the second private key may specifically include step S801 to step S803.
Step S801, the first segment encrypted data and the second segment encrypted data are combined to obtain initial encrypted data.
In an embodiment of the present application, the terminal device may combine the first piece of encrypted data with the second piece of encrypted data to obtain the initial encrypted data in a preset order, for example, the first piece of encrypted data is preceded and the second piece of encrypted data is followed.
Step S802, the initial encrypted data is transposed according to a first preset character length, and one character of the first private key is sequentially inserted after each transposition.
The first preset character length may be set as required, for example, may be set to be 3 characters long.
In the embodiment of the present application, the terminal device may perform transposition once every first preset character length on the initial encrypted data from the beginning, where transposition refers to reversing the character sequence, for example, transposition is performed on 3 characters abc, where the character after transposition is cba. At each transposition, one character of the first private key is inserted in turn after the character after the transposition.
For example, if the initial encrypted data is abcdef and the first private key is AB, performing first transposition on the initial encrypted data to obtain a character cba, and inserting a first character a of the first private key behind the character a to obtain a character cbaA; and performing second transposition on the initial encrypted data to obtain a character fed, inserting a second character B of the first private key behind the character d to obtain a character fedB, and combining the character cbaA obtained in front of fedB to obtain data cbaAfedB after the first private key is inserted.
In step S803, after the first private key is inserted, one character of the second private key is inserted in sequence after each transposition, so as to obtain encrypted data.
In the embodiment of the application, after the first private key is inserted, the terminal equipment can continue to insert the second private key after transposition at the moment, and finally the encrypted data is obtained.
For example, assuming that the initial encrypted data is abcdefghijkl, the first private key is AB, and the second private key is CD, in the example of step S802 described above, it has been found that the data inserted into the first private key after the transposition is cbaAfedB. And at the moment, continuing to transpose the initial encrypted data, and inserting the second private key into the transposed data. Specifically, the initial encrypted data is subjected to third transposition to obtain a character ihg, and a first character C of a second private key is inserted behind the character g to obtain a character ihgC; the initial encrypted data is transposed a fourth time to obtain a character lkj, a second character D of the second private key is inserted after the character j to obtain a character lkjD, and the character ihgC obtained before lkjD is combined to obtain data ihgClkjD after the second private key is inserted. And then ihgClkjD is combined with the data cbaAfedB inserted with the first private key to obtain encrypted data cbaAfedBihgClkjD.
According to the embodiment of the application, the initial encrypted data is transposed, and the first private key and the second private key are inserted into the transposed initial encrypted data, so that the encrypted data is finally obtained, and the confidentiality of the encrypted data is further improved.
In some embodiments of the present application, the first half data is ECC encrypted based on the fingerprint information, and a first private key is generated and first segment encrypted data is obtained, which may specifically include step S901 and step S902.
Step S901 generates a third private key based on fingerprint information.
In step S902, the first half of data is ECC encrypted based on the third private key, and the first private key is generated and the first piece of encrypted data is obtained.
In the embodiment of the application, the terminal equipment can generate the public key and the private key according to the fingerprint information by utilizing an RSA algorithm, wherein the private key is the third private key. After the third private key is obtained, the terminal equipment can use the third private key as a public key in ECC encryption, and the public key is used for ECC encryption of the first half part of data to obtain first segmented encrypted data after ECC encryption. Meanwhile, in the ECC encryption process, a public key and a private key are generated, wherein the private key is the first private key.
In some embodiments of the present application, the ECC encryption may be performed on the second half of data based on the eyeball information, and the second private key may be generated and the second segment encrypted data may be obtained, which may specifically include step S1001 and step S1002.
Step S1001 generates a fourth private key based on eyeball information.
In step S1002, the second half data is ECC encrypted based on the fourth private key, and a second private key is generated and second segment encrypted data is obtained.
In the embodiment of the application, the terminal equipment can also generate the public key and the private key according to eyeball information by utilizing an RSA algorithm, wherein the private key is the fourth private key. After the fourth private key is obtained, the terminal equipment can use the fourth private key as a public key in ECC encryption, and the public key is used for ECC encryption of the second half part of data to obtain second segment encrypted data after ECC encryption. Meanwhile, in the ECC encryption process, a public key and a private key are generated, wherein the private key is the second private key.
To facilitate understanding of the encryption process, specific examples are: for example, as shown in fig. 2, assume that the original data is aaabbbcccddd, the fingerprint information is 010100101, and the eyeball information is 101001100. The terminal device may divide the original data into first half data aaabbb and second half data cccddd. And generates a third private key adcrws based on the fingerprint information 010100101 and a fourth private key 0fe8& fah based on the eyeball information 101001100. The first half of the data aaabbb may then be ECC encrypted using the third private key adcrws to obtain first piece of encrypted data YWFh k0YmJiY2NjkkL and generate a first private key fksdf #. The second half data cccddd may be ECC encrypted by using the fourth private key 0fe8& fah to obtain second segmented encrypted data JHHh12YggayYSGfafb, and generate the second private key 46× #f &. Next, the first piece of encrypted data YWFh k0YmJiY2NjkkL is combined with the second piece of encrypted data JHHh12YggayYSGfafb, and initial encrypted data YWFh k0YmJiY2NjkkLJHHh12YggayYSGfafb can be obtained. The original encrypted data is then transposed by 3 characters in length (the order of the 3 characters is transposed), and the transposed data is FWYk, hmY, yiJjN, lkkHHJ, hggYYYafGSbfa. After each transposition, the first private key fksdf # and the second private key 46 x#f &aresequentially inserted, that is, the characters of the first private key fksdf # and the second private key 46 x#f & are sequentially inserted every 3 characters in the data after the transposition, and finally the encrypted data FWYfk3hkmY0sYiJdjN2fLkk #HHJ421h6ggY x YYa # fGSfbfa &canbe obtained.
It will be appreciated that after the encryption of the original data is completed, the login user may be given data operation rights and the data operation rights may be encrypted. When a user logs in, login information can be obtained and verified, and if the verification is passed, the data operation authority is decrypted and given to the user.
In some scenarios, after encrypting the original data, the encrypted data needs to be decrypted, so the embodiment of the application provides a data decryption method, which can decrypt the encrypted data obtained based on the data encryption method.
In order to illustrate the technical scheme of the application, the following description is made by specific examples.
Fig. 3 is a schematic implementation flow chart of a data decryption method according to an embodiment of the present application, where the method may be applied to a terminal device. The terminal device may be a mobile phone, tablet computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, etc.
Specifically, the data decryption method may include the following steps S301 to S306.
Step S301, obtaining encrypted data to be decrypted.
In an embodiment of the present application, the terminal device may read the encrypted data stored in its internal memory. Of course, the encrypted data may be obtained in other manners, which the present application is not limited to.
Step S302, the encrypted data is turned over to obtain first segmented encrypted data, second segmented encrypted data, a first private key and a second private key.
In the embodiment of the application, the terminal equipment can overturn the encrypted data and extract the first segmented encrypted data, the second segmented encrypted data, the first private key and the second private key from the encrypted data.
Step S303, fingerprint information and eyeball information are acquired.
In the embodiment of the application, the terminal equipment can collect fingerprint data and eyeball data of a user through the terminal equipment or other encryption equipment electrically connected with the terminal equipment. Fingerprint data and eyeball data are obtained, and the terminal equipment can convert the fingerprint data and the eyeball data into corresponding binary data, so that binary fingerprint information and eyeball information are obtained.
Step S304, ECC decryption is carried out on the first segment encrypted data according to the fingerprint information and the first private key, and the first half part of data is obtained.
Wherein the first half data is the first half data of the original data.
In the embodiment of the application, the encrypted data is subjected to ECC decryption, and a corresponding public key and a private key are needed, wherein the first private key is the private key needed for ECC decryption of the first segmented encrypted data, and the public key needed for ECC decryption can be obtained from the fingerprint information. Therefore, after obtaining the fingerprint information and the first private key, the terminal device can obtain the public key according to the fingerprint information, and combine the first private key to perform ECC decryption on the first segment encrypted data, thereby obtaining the first half data.
Step S305, ECC decryption is performed on the second segment encrypted data according to the eyeball information and the second private key, and the second half part of data is obtained.
The second half data is the second half data of the original data.
In the embodiment of the application, the encrypted data is subjected to ECC decryption, and a corresponding public key and a private key are needed, wherein the second private key is the private key needed for ECC decryption of the second segmented encrypted data, and the public key needed for ECC decryption can be obtained from eyeball information. Therefore, after the eyeball information and the second private key are obtained, the terminal device can obtain the public key according to the eyeball information and combine the second private key to perform ECC decryption on the second segment encrypted data, so that the second half data is obtained.
Step S306, combining the first half data and the second half data to obtain the original data.
In the embodiment of the present application, after the first half data and the second half data are obtained, the terminal device may obtain the original data by using the first half data and the second half data, specifically, the first half data and the second half data are before and after the first half data.
In some embodiments of the present application, the flipping the encrypted data to obtain the first segmented encrypted data, the second segmented encrypted data, the first private key and the second private key may specifically include steps S1101 to S1104.
Step 1101, the encrypted data is flipped according to the first preset character length, and a character is extracted after each flipping, so as to obtain the initial encrypted data.
In the embodiment of the application, the terminal device can overturn the encrypted data according to the first preset character length, which can be understood as transposition of the encrypted data, extraction of one character after each overturn, that is, extraction of the latter character every first preset character length, and finally obtaining the initial encrypted data.
Illustratively, assume that the encrypted data is cbaAfedBihgClkjD and the first predetermined character length is 3. And performing first overturn on the encrypted data cbaAfedBihgClkjD according to the length of 3 characters to obtain characters abc, and extracting the characters after the first overturn to obtain characters A. And (5) performing second overturn to obtain a character def, and extracting the character after the second overturn to obtain a character B. And (3) performing third overturn to obtain a character ghi, and extracting the character after the third overturn to obtain a character C. And performing fourth overturn to obtain a character jkl, and extracting the character after the fourth overturn to obtain a character D. The initial encrypted data abcdefghijkl, as well as the characters A, B, C, D, are ultimately available.
In step S1102, when the extracted character length meets the second preset character length, the extracted characters are sequentially formed into the first private key.
It can be appreciated that the second predetermined character length is identical to the lengths of the first private key and the second private key in the encryption process.
In the embodiment of the application, after the extracted characters are obtained, the terminal equipment can sequentially form the extracted characters into the first private key according to the second preset character length.
For example, referring to the example of step S1101, assuming that the second preset character length is 2, the terminal device may combine a and B in the extracted characters A, B, C, D into the first private key AB.
In step S1103, after the first private key is obtained, the characters extracted again are sequentially formed into the second private key.
In the embodiment of the application, after the first private key is obtained, the terminal device can sequentially form the remaining characters in the extracted characters into the second private key.
For example, referring to the examples of step S1101 and step S1102 described above, assuming that the second preset character length is 2, the terminal device may combine C and D remaining in the extracted character A, B, C, D into the second private key CD.
In step S1104, the initial encrypted data is decomposed to obtain the first segmented encrypted data and the second segmented encrypted data.
In the embodiment of the application, after the initial encrypted data is obtained, the terminal device can divide the initial encrypted data evenly to obtain the first segmented encrypted data and the second segmented encrypted data.
In some embodiments of the present application, the first segment encrypted data is subjected to ECC decryption according to the fingerprint information and the first private key to obtain first half data, which may specifically include step S1201 and step S1202.
Step S1201, a third private key is generated based on the fingerprint information.
In step S1202, the third private key is used as the public key corresponding to the first private key, and ECC decryption is performed on the first segment encrypted data in combination with the first private key to obtain the first half data.
In the embodiment of the application, the terminal equipment can generate the public key and the private key according to the fingerprint information by utilizing an RSA algorithm, wherein the private key is the third private key. Since the first half data is ECC encrypted using the third private key at the time of ECC encryption of the first half data, the public key and the first private key are generated during this encryption. Therefore, the terminal device can use the third private key as the public key corresponding to the first private key, and combine the first private key to perform ECC decryption on the first segment encrypted data, thereby obtaining the first half data.
In some embodiments of the present application, the ECC decryption is performed on the second segment encrypted data according to the eyeball information and the second private key to obtain the second half data, which may specifically include step S1301 and step S1302.
Step S1301 generates a fourth private key based on eyeball information.
In step S1302, the fourth private key is used as the public key corresponding to the second private key, and the second segment encrypted data is ECC decrypted in combination with the second private key to obtain the second half data.
In the embodiment of the application, the terminal equipment can generate the public key and the private key according to eyeball information by utilizing an RSA algorithm, wherein the private key is the fourth private key. Since the second half of the data is ECC-encrypted using the fourth private key at the time of ECC-encrypting the second half of the data, the public key and the second private key are generated during this encryption.
