In order to prevent the service data from being stolen, the embodiment of the application provides a service data theft preventing method and system based on artificial intelligence.
The service data theft prevention method based on artificial intelligence provided by the embodiment of the application can be applied to a user terminal or a server. It will be appreciated that the execution body is not to be construed as limiting the embodiments of the application.
The service data anti-theft method based on artificial intelligence provided by the embodiment of the application is described in detail below.
As shown in fig. 1, a flowchart of an artificial intelligence-based service data theft prevention method according to a first aspect of the present application may include, but is not limited to, the following steps S101 to S106.
And S101, extracting characters in the service data according to a preset step length and then combining the extracted characters according to the step length to obtain the processed service data.
In the embodiment of the application, one or more step sizes can be preset according to the requirement, a plurality of step sizes can be preferably set for improving the safety of the data, and characters in the service data are sequentially extracted according to the step sizes and then combined according to the step sizes, so that the processed service data are obtained.
For example, the step size is K, where K is a positive integer greater than or equal to 2, and the characters in the service data are extracted according to the step size and then combined to obtain the processed service data, which may include, but is not limited to, the following steps S1011-S1013.
And S1011, extracting the characters in the latest service data according to the kth step length to obtain a plurality of character segments, wherein the initial value of k is 1.
The content of the service data is "ABCDEFGHIJKL", and the 1 st step is 3, and then one character can be extracted every 3 characters to be combined, so as to obtain 3 character segments "ADGJ", "BEHK" and "CFIL".
And S1012, sequentially combining the extracted plurality of character segments to obtain new service data.
Still based on the example in the aforementioned step S1011, the 3 character segments are sequentially combined to obtain new service data, i.e. "ADGJBEHKCFIL".
Step S1013, let K add 1 by itself, and extract the character in the latest business data according to the kth step length, get multiple character segments, and combine the multiple extracted character segments in turn, get new business data, until k=K, stop extracting the character in the latest business data.
After new service data is obtained by extraction and combination based on the 1 st step length, k is self-added with 1, characters in the latest service data are extracted again according to the k th step length, a plurality of character segments are obtained, and the extracted plurality of character segments are combined in sequence, so that the new service data is obtained. At this time, the characters in the latest service data can be extracted according to the 2 nd step length to obtain a plurality of character segments, and the extracted plurality of character segments are sequentially combined to obtain new service data.
After new service data is obtained by extraction and combination based on the 2 nd step length, the character in the latest service data can be extracted continuously according to the 3 rd step length to obtain a plurality of character segments, and the extracted plurality of character segments are combined in sequence to obtain the new service data. And so on until new service data is obtained by extraction and combination based on the Kth step length.
In the embodiment of the application, characters in the service data are extracted according to step length and then combined to obtain the processed service data. It will be appreciated that in other embodiments, the characters in the service data may be converted into a binary code sequence, and then the binary codes in the binary code sequence are extracted and combined according to step sizes, so as to obtain the processed service data (binary code sequence).
Based on the above mode, the business data can be encrypted once, and the more complex the processed business data is, the less easily the business data is cracked along with the increase of the step size. However, in this way, since the first character in the service data is in the first position, after being extracted and combined according to a plurality of step sizes, the first character still does not change in the new service data, that is, the first character in the service data cannot be encrypted.
Based on this, in order to encrypt the whole service data, before extracting and combining the characters in the service data according to at least one preset step, a designated character may be inserted before the first character of the service data, and when the characters in the service data are extracted and combined according to the step, the characters in the service data inserted with the designated character may be extracted and combined according to the step according to at least one preset step. Thus, the first character in the service data is changed into the second character, so that the encryption of the whole service data can be realized. It will be appreciated that in this way, the first character in the decrypted service data needs to be removed during subsequent decryption.
S102, converting each character in the processed service data into a binary code to obtain a binary code sequence.
S103, dividing the binary coding sequence into coding segments with specified lengths to obtain a plurality of binary coding segments.
The specified length may be set according to practical situations, for example, may be 8 bits, 16 bits, 32 bits, or the like, and in the embodiment of the present application, the specified length is 16 bits.
In one or more embodiments, after dividing the binary sequence into code segments with a specified length to obtain a plurality of binary code segments, the length of the last binary code segment in the plurality of binary code segments may be lower than the specified length (for example, the specified length is 16 bits, and the length of the last binary code segment is 8 bits), and then the data of the last binary code segment in the plurality of binary code segments may be padded so that the length of the last binary code segment in the plurality of binary code segments is equal to the specified length.
Wherein, when data is filled, a binary character 0 can be added after the last binary coding segment. For example, the length is designated as 16 bits, and the last binary segment is 00110011, and after data padding is performed on the last binary segment, the obtained binary segment may be 0011001100000000.
S104, carrying out logic operation on the preset initial binary code segment and a first binary code segment in the plurality of binary code segments, and encrypting a logic operation result through an encryption key to obtain a ciphertext segment corresponding to the first binary code segment in the plurality of binary code segments.
The length of the initial binary code is the same as the length of any binary code segment in the plurality of binary code segments, for example, the lengths of the plurality of binary code segments are all 16 bits, and then the length of the initial binary code is also 16 bits.
The initial binary segment is logically operated on with a first binary segment of the plurality of binary segments, which may be, but is not limited to, an exclusive or operation or an exclusive or operation. In the embodiment of the application, the exclusive OR operation can be performed on the preset initial binary coding section and the first binary coding section in the plurality of binary coding sections.
After the exclusive-or operation is performed, the logical operation result may be encrypted by an encryption key to obtain a ciphertext segment corresponding to a first binary code segment of the plurality of binary code segments, where the ciphertext segment has a length identical to a length of the binary code segment. In the embodiment of the application, the logic operation result can be encrypted by an advanced encryption standard (Advanced Encryption Standard, AES) algorithm based on the encryption key. The AES algorithm includes four steps of key expansion, initial round, repetition round, and final round, the specific principles of which are not described in detail in the embodiments of the present application.
S105, carrying out logic operation on the (i+1) th binary code segment in the plurality of binary code segments and the ciphertext segment corresponding to the (i+1) th binary code segment in the plurality of binary code segments, and then encrypting a logic operation result through an encryption key to obtain the ciphertext segment corresponding to the (i+1) th binary code segment in the plurality of binary code segments.
Wherein i is a positive integer.
Specifically, the 2 nd binary code segment and the ciphertext segment corresponding to the 1 st binary code segment in the plurality of binary code segments are subjected to logic operation, and then the logic operation result is encrypted through an encryption key to obtain the ciphertext segment corresponding to the 2 nd binary code segment in the plurality of binary code segments. And then carrying out logic operation on the 3 rd binary coding section and the ciphertext section corresponding to the 2 nd binary coding section in the plurality of binary coding sections, encrypting a logic operation result through an encryption key to obtain the ciphertext section corresponding to the 3 rd binary coding section in the plurality of binary coding sections, and the like to obtain the ciphertext section corresponding to each binary coding section in the plurality of binary coding sections.
In the embodiment of the application, since the initial binary code segment and the first binary code segment in the plurality of binary code segments are subjected to exclusive or operation, the subsequent logic operation is also an exclusive or operation, that is, the (i+1) th binary code segment in the plurality of binary code segments is subjected to exclusive or operation with the ciphertext segment corresponding to the (i) th binary code segment in the plurality of binary code segments.
S106, sequentially combining ciphertext segments corresponding to the binary coding segments in the plurality of binary coding segments to obtain encrypted data corresponding to the service data.
In one or more embodiments, after sequentially combining ciphertext segments corresponding to each binary code segment in the plurality of binary code segments to obtain encrypted data corresponding to service data, the encrypted data may be converted into a character according to binary codes of every 8 bits, and the encrypted data may be converted into a character sequence.
According to the service data theft prevention method based on artificial intelligence, characters in service data are extracted according to the preset step length and then combined to obtain processed service data, so that primary encryption of the service data can be realized; then converting each character in the processed service data into binary codes to obtain binary code sequences; dividing the binary coding sequence into coding segments with specified lengths to obtain a plurality of binary coding segments; carrying out logic operation on a preset initial binary coding section and a first binary coding section in the plurality of binary coding sections, and encrypting a logic operation result through an encryption key to obtain a ciphertext section corresponding to the first binary coding section in the plurality of binary coding sections, wherein the length of the initial binary coding is the same as the length of any binary coding section in the plurality of binary coding sections; performing logic operation on the (i+1) th binary code segment in the plurality of binary code segments and a ciphertext segment corresponding to the (i) th binary code segment in the plurality of binary code segments, and then encrypting a logic operation result through an encryption key to obtain a ciphertext segment corresponding to the (i+1) th binary code segment in the plurality of binary code segments, wherein i is a positive integer; and sequentially combining ciphertext segments corresponding to each binary code segment in the plurality of binary code segments to obtain encrypted data corresponding to the service data, so that the service data after primary encryption can be secondarily encrypted through the initial binary code segment and the encryption key. Therefore, multiple encryption of the service data can be realized, the security of the service data is improved, the service data is further effectively prevented from being stolen, serious safety risks and economic losses caused by the leakage of the service data are avoided, and the method is convenient for practical application and popularization.
