In one case, the preset data length provided in this embodiment may be equal to the data length of the initial CPLC data, so the data values of the target types provided in this embodiment are the data values of all the target types included in the initial CPLC data. Illustratively, the initial CPLC data provided by the present embodiment may be:

The data value of the target type provided in this embodiment includes "F", "B", "D" and "F".

In another case, the preset data length provided in this embodiment may be 1/3 of the data length of the initial CPLC data, and the continuous data value corresponding to 1/3 may be a continuous data value at any position in the initial CPLC data, for example, the continuous data value corresponding to 1/3 may be a continuous data value calculated from the first data value of the initial CPLC data, and the continuous data value corresponding to 1/3 may also be a continuous data value calculated from the second data value of the initial CPLC data, as long as the position corresponding to 1/3 is in the initial CPLC data, which is not limited herein.

The following describes in detail the data verification process performed on the second CPLC data by the second terminal 20, which is the technical solution that the data processing method provided in this embodiment is applied to the second terminal 20, that is, before the second terminal 20 uses or transmits the received second CPLC data.

Referring to fig. 5, fig. 5 is another flow chart of the data processing method according to the embodiment of the present invention, as shown in fig. 5, the data processing method according to the embodiment of the present invention includes steps 501 to 504;

and step 501, receiving second CPLC data and information of a first conversion strategy sent by the first terminal.

In this embodiment, when the information of the second CPLC data and the first conversion policy sent by the first terminal is received, the purpose of performing data verification on the received second CPLC data can be achieved through the second CPLC data and the first conversion policy, so that the use of erroneous second CPLC data is avoided, and the normal work of the user is affected. For specific data verification, please refer to the following steps 502 to 504.

And step 502, performing character conversion processing on the data value of the target type in the second CPLC data according to the first conversion strategy to obtain third CPLC data.

In this embodiment, the target type is a letter type. The first conversion policy provided in this embodiment is a first conversion policy used by the first terminal 10, and the first conversion policy is mainly used for performing character conversion processing on the data value of the letter type in the CPLC data.

In this embodiment, the first conversion policy used by the first terminal 10 is adopted to perform character conversion processing on the target type of data value in the second CPLC data received by the second terminal 20, so that the second CPLC data is converted into first CPLC data obtained by preprocessing the initial CPLC data by the first terminal 10, and the third CPLC data obtained by performing character conversion processing on the initial CPLC data by using the second CPLC data in the following manner, that is, the hash value of the first CPLC data obtained by preprocessing the initial CPLC data by the first terminal 10 is convenient, and the data verification is performed on the second CPLC data, thereby achieving the purpose of performing data verification on the received second CPLC data.

As an alternative embodiment, since the first terminal 10 provided in this embodiment may perform the encoding operation processing on only the continuous data value of the preset data length in the initial CPLC data, so as to perform the character conversion processing on only the data value of the target type in the continuous data value of the preset data length in the initial CPLC data, the second terminal 20 provided in this embodiment needs to determine the target data length processed by the first terminal 10 during the character conversion processing before performing the data verification on the second CPLC data. Specifically, the step of performing character conversion processing on the data value of the target type in the second CPLC data according to the first conversion policy to obtain the third CPLC data may be: and acquiring the target data length of the second CPLC data subjected to character conversion processing in the first terminal, and performing character conversion processing on the data value of the target type in the data values contained in the target data length in the second CPLC data according to the first conversion strategy to obtain third CPLC data.

It should be noted that, the target data length provided in this embodiment is the preset data length for performing the encoding operation in the first terminal 10, and therefore, the target data length is also the same as the preset data length, so the target data length provided in this embodiment may be the same data length as the data length of the second CPLC data, or may be any number of data lengths such as 1/3 or 1/2 of the data length of the second CPLC data, so long as the target data length is the same as the preset data length, and the position where the continuous data value in the target data length in the second CPLC data is located is the same as the position where the continuous data value in the preset data length for performing the character conversion process in the first terminal 10 is located in the initial CPLC data, which is not particularly limited herein.

In one embodiment, the first conversion policy includes a policy of converting a data value of a letter type into an uppercase letter, and the step of performing, according to the first conversion policy, character conversion processing on the data value of the target type in the data value included in the target data length in the second CPLC data, to obtain third CPLC data may be: and converting letters in the data value of the target type contained in the target data length in the second CPLC data into capital letters according to the first conversion strategy to obtain third CPLC data.

Illustratively, the target data length provided in this embodiment may be the same data length as the data length of the second CPLC data, and the second CPLC data provided in this embodiment may be:

the third CPLC data obtained after the character conversion process is performed on the second CPLC data by the first conversion policy is:

in this embodiment, the data values "F", "B", "D" and "F" of the four letter types in the second CPLC data are subjected to the character conversion process to obtain "F", "B", "D" and "F".

In another embodiment, the first conversion policy includes a policy of converting a data value of a letter type into a lower case letter, and the step of performing, according to the first conversion policy, character conversion processing on the data value of the target type in the data values included in the target data length in the second CPLC data, to obtain third CPLC data may be: and converting letters in the data value of the target type contained in the target data length in the second CPLC data into lower case letters according to the first conversion strategy to obtain third CPLC data.

In step 503, hash operation is performed on the third CPLC data to obtain a second hash value.

In this embodiment, the SHA secure hash algorithm adopted in the hash operation processing procedure provided in this embodiment may be a SHA384 algorithm.

Illustratively, the third CPLC data provided in this embodiment may be:

then hash operation processing is performed on the third CPLC data by using SHA384 algorithm, and the processing procedure for obtaining the second hash value may be:

SHA384(479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647)

＝>

step 504, determining the integrity of the second CPLC data according to the second hash value.

In this embodiment, the integrity of the second CPLC data is determined based on the uniqueness of the hash value obtained by the hash operation processing. Specifically, if the second CPLC data obtained by the second terminal 20 is correct and complete, the third CPLC data obtained by performing the character conversion process corresponding to the first conversion policy on the second CPLC should be identical to the first CPLC data obtained by preprocessing the initial CPLC by the first terminal 10, and since the second terminal 20 cannot know whether the third CPLC data is identical to the first CPLC data obtained by the first terminal 10, the embodiment determines the integrity of the second CPLC data received by the second terminal 20 by using the characteristic that the hash value corresponding to the identical data is identical, and using the hash value of the first CPLC data and the processing rule of performing the character conversion process on the target type data value in the first CPLC data by using the hash value of the first CPLC data and the second conversion policy (the policy opposite to the first conversion policy).

As an alternative embodiment, this embodiment determines whether the data value of the corresponding target type in the second CPLC data has undergone the character conversion process of the second conversion policy in the first terminal 10 according to the data value in the same position in the second hash value as the data value of the target type of the letter type in the second CPLC data, thereby determining the correctness of the data value of the target type in the second CPLC. That is, in this embodiment, the correctness of the target type of data value in the second CPLC is determined by determining the relation between the case format of the target value in the second CPLC data and whether the data value at the corresponding position in the second hash value satisfies the preset condition. In this way, the data value of the target type in the second CPLC data provided in this embodiment is equivalent to the check code capable of performing data check processing, so that the second CPLC data can be subjected to data check, thereby effectively improving the reliability and safety of the CPLC data, and avoiding that the second terminal 20 uses the second CPLC data that is wrong or incomplete, and affecting the normal operation of the second terminal 20.

In some embodiments, please refer to fig. 6, fig. 6 is a flow chart of a data verification process provided in the embodiment of the present invention, as shown in fig. 6, including steps 5041 to 5043;

In step 5041, a second target location of the data value of the target type in the second CPLC data is determined.

Illustratively, the second CPLC data provided in this embodiment may be:

the second target position of the target type of data value (letter type of data value) in the second CPLC data may be determined, specifically, the second target position of the target type of data value "F" in the second CPLC data is the position of the 13 th data value, the second target position of the target type of data value "b" in the second CPLC data is the position of the 60 th data value, the second target position of the target type of data value "D" in the second CPLC data is the position of the 61 st data value, and the second target position of the target type of data value "F" in the second CPLC data is the position of the 62 th data value.

Step 5042, determining a second data value at a second target location in the second hash value.

The second hash value corresponding to the third CPLC data provided in the foregoing embodiment is exemplified as:

the second data value at the second target position in the second hash value may be determined, specifically, the second data value is d when the second target position is the position of the 13 th data value, the second data value is 6 when the second target position is the position of the 60 th data value, the second data value is c when the second target position is the position of the 61 th data value, and the second data value is 8 when the second target position is the position of the 62 th data value.

In step 5043, if the second data value meets the preset condition and the size format of the letter in the data value of the target type is not the target format, the second CPLC data is determined to be complete data.

In this embodiment, the target format is a size format of letters in the data value of the target type after the character conversion processing of the first conversion policy. The preset conditions provided in this embodiment are the same as the preset conditions set in the first terminal 10, that is, the preset conditions provided in this embodiment are determined based on the magnitude relation between the second data value and the preset threshold, and specifically, in one case, the preset conditions provided in this embodiment may be that the second data value is not greater than the preset threshold; in another case, the preset condition provided by the present embodiment may be that the second data value is greater than the preset threshold. Since the CPLC data provided in this embodiment is data composed of hexadecimal data, the preset threshold provided in this embodiment may be 6 or 7, and the preset threshold is not limited in this embodiment, and any data value in hexadecimal may be used, that is, any data value in 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and a, b, c, d, e, f may be used.

In one embodiment, the first conversion policy adopted in the embodiment may be a policy of converting a data value of a letter type into a capital letter, and the target format provided in the embodiment is a capital format, that is, it is required to determine that the second CPLC data is complete data when it is detected that the second data value meets a preset condition and the size format of the letter in the data value of the target type is not the capital format.

Specifically, the preset threshold value adopted in this embodiment may be 8, and the preset condition adopted in this embodiment may be that the second data value is not greater than the preset threshold value 8, and illustratively, the second CPLC data adopted in this embodiment may be:

the third CPLC data is:

the second hash value corresponding to the third CPLC data is:

it may be determined that the second data values are d, 6, c, 8, respectively, and thus it may be determined that the second data value d does not satisfy the preset condition, the second data value 6 satisfies the preset condition, the second data value c does not satisfy the preset condition, and the second data value 8 satisfies the preset condition.

In this embodiment, if the second data value is detected to satisfy the preset condition and the size format of the letters in the data value of the target type is not the target format, the second CPLC data is determined to be complete data, that is, if the second data value is detected to be not greater than the preset threshold 8 and the size format of the letters in the data value of the target type is detected to be not the upper case format, the second CPLC data can be determined to be complete data. Therefore, the data verification method provided in this embodiment specifically includes: if the second data value d does not meet the preset condition, the second data value d corresponds to the data value "F" of the target type in the second CPLC data and should be in the uppercase format; if the second data value 6 meets the preset condition, the data value "b" of the second CPLC data corresponding to the target type should not be in the uppercase format but should be in the lowercase format; if the second data value c does not meet the preset condition, the second data value c corresponds to the data value "D" of the target type in the second CPLC data and should be in capitalization format; if the second data value 8 satisfies the preset condition, the second data value 8 corresponds to the data value "f" of the target type in the second CPLC data, which should not be in uppercase format but should be in lowercase format.

Based on the specific data verification process provided in the foregoing embodiment, it can be known that the size format of the data value of the target type in the second CPLC data provided in the present embodiment passes the data verification, so it can be determined that the second CPLC data provided in the present embodiment is integrity.

In another embodiment, the first conversion policy may also be a policy of converting a data value of a letter type into a lower case letter, and the target format provided in this embodiment is a lower case format, that is, it is required to determine that the second CPLC data is complete data when it is detected that the second data value meets a preset condition and the size format of the letter in the data value of the target type is not the lower case format. The specific data verification process refers to the method provided in the above embodiment, and is not described herein.
