[0068] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0069] It should be understood that the steps described in the method embodiments of this disclosure may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this disclosure is not limited in this respect.

[0070] The term "comprising" and its variations as used herein are open-ended inclusions, meaning "including but not limited to". The term "based on" means "at least partially based on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Definitions of other terms will be given in the description below.

[0071] In related technologies, CPLC data encoding typically involves transmitting and storing CPLC data in hexadecimal encoding. Specifically, CPLC data is divided into several small blocks, each containing 2 to 4 hexadecimal characters. These small blocks are then arranged in sequence to form an 84-byte long string, which serves as the CPLC encoded data. This CPLC encoded data is then transmitted and stored.

[0072] However, the following drawbacks exist in the encoding process of CPLC data in related technologies:

[0073] 1. Because CPLC data is quite long, it is easy to make mistakes or omit characters during the hexadecimal encoding process, resulting in data errors or incomplete data;

[0074] 2. The encoding method of CPLC data does not use error correction codes or other technologies for data verification and correction, which cannot effectively guarantee the integrity of the CPLC data used.

[0075] 3. The encoding method of CPLC data does not take into account data encryption and security issues, making it vulnerable to malicious data tampering and attacks.

[0076] Therefore, a new CPLC encoding technology is urgently needed to solve the above problems.

[0077] To address the technical problems existing in related technologies, embodiments of the present invention provide a data processing method. Please refer to [link / reference needed]. Figure 1 , Figure 1 This is an application scenario diagram of CPLC data usage provided in the embodiments of the present invention, wherein, Figure 1 In the middle, 10 represents the first terminal, which is mainly used to acquire CPLC data and encode the CPLC data to provide a check code for integrity verification of the CPLC data, thereby improving the reliability of the CPLC data. Figure 120 in the middle represents the second terminal. The second terminal 20 is mainly used to use or transmit CPLC data. Before using or transmitting, it is necessary to determine whether the CPLC data used is correct or complete, so as to avoid using incorrect CPLC data and affecting the normal work of the user.

[0078] For details, please continue reading. Figure 1 The CPLC data provided in this embodiment of the invention is first encoded by a first terminal 10. After obtaining the encoded CPLC data with a checksum, the CPLC data is sent to a second terminal 20. Upon receiving the encoded CPLC data with the checksum, the second terminal 20 verifies the data using the checksum to determine the integrity of the received CPLC data. After confirming that the received CPLC data is complete and error-free, it can be used or transmitted. This achieves the purpose of verifying the CPLC data before use or transmission, preventing input errors or missing characters when using or transmitting the CPLC data.

[0079] The data processing method provided in this embodiment can be applied to the first terminal 10 to implement the encoding process of CPLC data. For details, please refer to... Figure 2 , Figure 2 This is a flowchart illustrating a data processing method provided in an embodiment of the present invention, which includes steps 201 to 205.

[0080] Step 201: Obtain the initial CPLC data to be encoded.

[0081] The initial CPLC data provided in this embodiment includes at least one data value of letter type.

[0082] In this embodiment, CPLC data is the data required by NFC technology. This CPLC data can be obtained from the integrated circuit card (Smart Card, IC card) via NFC technology, or it can be obtained from IC card information entered by the user. Therefore, this embodiment does not limit the method / process of obtaining CPLC data. The CPLC data provided in this embodiment is mainly used to identify and verify the legitimacy of the IC card. CPLC data includes the IC card's manufacturer information, IC card serialization information, IC card production date information, etc.

[0083] In this embodiment, the initial CPLC data provided is CPLC data that requires encoding. Specifically, CPLC data is typically a long string consisting of 84 bytes. For example, the initial CPLC data provided in this embodiment can be:

[0084] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0085] Step 202: Using a preset first conversion strategy, the target type data values ​​in the initial CPLC data are converted into characters to obtain the first CPLC data.

[0086] In this embodiment, the target type is an alphabetic type. For example, the data value of the target type provided in this embodiment can be the data value corresponding to "F", "B", "D", and "F" in the initial CPLC data provided in the above embodiment. The first conversion strategy provided in this embodiment is a pre-defined strategy, which is mainly used to perform character conversion processing on the alphabetic data values ​​in the CPLC data. Specifically, the first conversion strategy provided in this embodiment can perform character conversion processing on the data values ​​corresponding to "F", "B", "D", and "F" in the initial CPLC data provided in the above embodiment.

[0087] In this embodiment, after obtaining the initial CPLC data, it is necessary to preprocess the initial CPLC data before subsequent encoding operations can be performed. Specifically, this preprocessing is the character conversion processing corresponding to the first conversion strategy provided in this embodiment. The character conversion processing provided in this embodiment mainly converts the case format of letter-type data values. By only converting the case format of letter-type data values, the preprocessing of the initial CPLC data can be completed without modifying the data values ​​in the initial CPLC data, ensuring the integrity of the initial CPLC data, so that the preprocessed initial CPLC data can be used for subsequent encoding operations.

[0088] In one implementation, the first conversion strategy includes a strategy to convert letter-type data values ​​to uppercase letters. The step of using the preset first conversion strategy to perform character conversion processing on the target type data values ​​in the initial CPLC data to obtain the first CPLC data can be: using the preset first conversion strategy to convert the target type data values ​​in the initial CPLC data to uppercase letters to obtain the first CPLC data.

[0089] For example, the initial CPLC data provided in this embodiment may be:

[0090] 479007644701f3560600917409140030136748100000005100000449483bdf5380010000000000354647

[0091] The first CPLC data obtained after the initial CPLC data undergoes character conversion processing using the first conversion strategy is:

[0092] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0093] In this embodiment, the four letter data values ​​"f", "b", "d" and "f" in the initial CPLC data are converted into characters to obtain "F", "B", "D" and "F".

[0094] In another implementation, the first conversion strategy includes a strategy to convert letter-type data values ​​to lowercase letters. The step of using the preset first conversion strategy to perform character conversion processing on the target type data values ​​in the initial CPLC data to obtain the first CPLC data can be: using the preset first conversion strategy to convert the target type data values ​​in the initial CPLC data to lowercase letters to obtain the first CPLC number.

[0095] For example, the initial CPLC data provided in this embodiment may be:

[0096] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0097] The first CPLC data obtained after the initial CPLC data undergoes character conversion processing using the first conversion strategy is:

[0098] 479007644701f3560600917409140030136748100000005100000449483bdf5380010000000000354647

[0099] In this embodiment, the four letter data values ​​"F", "B", "D" and "F" in the initial CPLC data are converted into characters to obtain "f", "b", "d" and "f".

[0100] Step 203: Perform a hash operation on the first CPLC data to obtain the first hash value.

[0101] In this embodiment, the hash operation provided can be performed using the SHA secure hash algorithm. Specifically, the SHA secure hash algorithm provided in this embodiment can be SHA1, SHA256, SHA384, etc. By performing a hash operation on the first CPLC data, a first hash value corresponding to the first CPLC data can be generated, which facilitates subsequent character conversion processing of the first CPLC data based on the first hash value, thereby achieving the purpose of providing a checksum for the first CPLC data and improving the security and reliability of the first CPLC data.

[0102] For example, the first CPLC data provided in this embodiment may be:

[0103] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0104] Then, a hash operation is performed on the first CPLC data, and the first hash value is obtained as follows:

[0105] 14d2fd9806bfdcdd291a859dfff7ea0cdfcd77adfa1ea86b723e223d8b96c8cd243f848c2db4468f2ba34ddf03470a26

[0106] Step 204: Based on the first CPLC data, the first hash value, and the preset second conversion strategy, perform character conversion processing on the target type data value in the first CPLC data to obtain the second CPLC data.

[0107] In this embodiment, the first conversion strategy and the second conversion strategy are opposite conversion strategies. For example, when the first conversion strategy is to convert the data value of letter type to uppercase letters, the second conversion strategy is to convert the data value of letter type to lowercase letters; conversely, when the first conversion strategy is to convert the data value of letter type to lowercase letters, the second conversion strategy is to convert the data value of letter type to uppercase letters.

[0108] As an optional embodiment, this embodiment determines whether to use the second conversion strategy to perform character conversion processing on the target type data value in the first CPLC data based on the data value at the same position in the first hash value that is the same as the letter type data value in the first CPLC data.

[0109] In this embodiment, the CPLC data is processed by character conversion based on the first CPLC data, the first hash value, and the preset second conversion strategy to obtain the second CPLC data. The letter data values ​​in the second CPLC data can be used as check codes, enabling the second CPLC data to perform data verification. This allows the second terminal to verify the second CPLC data when using it, to determine the integrity of the second CPLC data, and to prevent the second CPLC data from being maliciously tampered with or attacked during transmission, thereby effectively improving the reliability and security of the CPLC data.

[0110] In one implementation, the first conversion strategy can be a strategy of converting letter-type data values ​​to uppercase letters. Therefore, during the character conversion processing of the target type data values ​​in the first CPLC data, the second conversion strategy used is a strategy of converting letter-type data values ​​to lowercase letters. For details, please refer to [link to relevant documentation]. Figure 3 , Figure 3 This is a schematic diagram of a character conversion process provided in an embodiment of the present invention, such as... Figure 3 As shown, steps 2041 to 2043 are included;

[0111] Step 2041: Determine the first target position in the first CPLC data for the target type data value.

[0112] For example, the first CPLC data provided in this embodiment may be:

[0113] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0114] Then the first target position of the target type data value (letter type data value) in the first CPLC data can be determined. Specifically, the first target position of the target type data value "F" in the first CPLC data is the position of the 13th data value, the first target position of the target type data value "B" in the first CPLC data is the position of the 60th data value, the first target position of the target type data value "D" in the first CPLC data is the position of the 61st data value, and the first target position of the target type data value "F" in the first CPLC data is the position of the 62nd data value.

[0115] Step 2042: Determine the first data value at the first target position in the first hash value.

[0116] For example, the first hash value corresponding to the first CPLC data provided in this embodiment is:

[0117] 14d2fd9806bfdcdd291a859dfff7ea0cdfcd77adfa1ea86b723e223d8b96c8cd243f848c2db4468f2ba34ddf03470a26

[0118] Then the first data value at the first target position in the first hash value can be determined. Specifically, when the first target position is the 13th data value, the first data value is d; when the first target position is the 60th data value, the first data value is 6; when the first target position is the 61st data value, the first data value is c; and when the first target position is the 62nd data value, the first data value is 8.

[0119] Step 2043: If the first data value meets the preset conditions, then the preset second conversion strategy is adopted to convert the data value of the target type corresponding to the first target position in the first CPLC data into lowercase letters to obtain the second CPLC data.

[0120] In this embodiment, the preset condition provided is determined based on the relationship between the first data value and the preset threshold. Specifically, in one case, the preset condition provided in this embodiment can be that the first data value is not greater than the preset threshold; in another case, the preset condition provided in this embodiment can be that the first data value is greater than the preset threshold. Since the CPLC data provided in this embodiment is composed of hexadecimal data, the preset threshold provided in this embodiment can be 6, 7, etc. This embodiment does not limit the preset threshold; any hexadecimal data value, that is, any data value among 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, and f, is acceptable.

[0121] As an optional embodiment, the preset threshold used in this embodiment can be 8, and the preset condition used in this embodiment can be that the first data value is not greater than the preset threshold 8. For example, the first CPLC data used in this embodiment can be:

[0122] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0123] The first hash value corresponding to the first CPLC data is:

[0124] 14d2fd9806bfdcdd291a859dfff7ea0cdfcd77adfa1ea86b723e223d8b96c8cd243f848c2db4468f2ba34ddf03470a26

[0125] Therefore, the first data values ​​can be determined to be d, 6, c, and 8. Thus, it can be determined that the first data value d does not meet the preset condition, the first data value 6 meets the preset condition, the first data value c does not meet the preset condition, and the first data value 8 meets the preset condition. At this point, the second conversion strategy is adopted to convert the target type data values ​​corresponding to the first data values ​​that meet the preset conditions in the same position in the first CPLC data to lowercase letters. Specifically, the target type data value "B" corresponding to the first data value 6 in the same position in the first CPLC data is converted to the lowercase letter "b", and the target type data value "F" corresponding to the first data value 8 in the same position in the first CPLC data is converted to the lowercase letter "f". In this way, the second CPLC data can be obtained:

[0126] 479007644701F3560600917409140030136748100000005100000449483bDf5380010000000000354647

[0127] In another implementation, the first conversion strategy can be a strategy of converting letter-type data values ​​to lowercase letters. Therefore, during the character conversion processing of the target type data values ​​in the first CPLC data, the second conversion strategy used is a strategy of converting letter-type data values ​​to uppercase letters. For details, please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is another schematic diagram of the character conversion process provided in the embodiment of the present invention, such as... Figure 4 As shown, steps 2044 to 2046 are included;

[0128] Step 2044: Determine the first target position in the first CPLC data for the target type data value.

[0129] For example, the first CPLC data provided in this embodiment may be:

[0130] 479007644701f3560600917409140030136748100000005100000449483bdf5380010000000000354647

[0131] Then the first target position of the target type data value (letter type data value) in the first CPLC data can be determined. Specifically, the first target position of the target type data value "f" in the first CPLC data is the position of the 13th data value, the first target position of the target type data value "b" in the first CPLC data is the position of the 60th data value, the first target position of the target type data value "d" in the first CPLC data is the position of the 61st data value, and the first target position of the target type data value "f" in the first CPLC data is the position of the 62nd data value.

[0132] Step 2045: Determine the first data value at the first target position in the first hash value.

[0133] For example, the first hash value corresponding to the first CPLC data provided in the above embodiments is:

[0134] 14d2fd9806bfdcdd291a859dfff7ea0cdfcd77adfa1ea86b723e223d8b96c8cd243f848c2db4468f2ba34ddf03470a26

[0135] Then the first data value at the first target position in the first hash value can be determined. Specifically, when the first target position is the 13th data value, the first data value is d; when the first target position is the 60th data value, the first data value is 6; when the first target position is the 61st data value, the first data value is c; and when the first target position is the 62nd data value, the first data value is 8.

[0136] Step 2046: If the first data value meets the preset conditions, then the preset second conversion strategy is adopted to convert the data value of the target type corresponding to the first target position in the first CPLC data into uppercase letters to obtain the second CPLC data.

[0137] As an optional embodiment, the preset threshold used in this embodiment can be 8, and the preset condition used in this embodiment can be that the first data value is not greater than the preset threshold 8. For example, the first CPLC data used in this embodiment is:

[0138] 479007644701f3560600917409140030136748100000005100000449483bdf5380010000000000354647

[0139] The first hash value corresponding to the first CPLC data is:

[0140] 14d2fd9806bfdcdd291a859dfff7ea0cdfcd77adfa1ea86b723e223d8b96c8cd243f848c2db4468f2ba34ddf03470a26

[0141] Therefore, the first data values ​​can be determined to be d, 6, c, and 8. Thus, it can be determined that the first data value d does not meet the preset condition, the first data value 6 meets the preset condition, the first data value c does not meet the preset condition, and the first data value 8 meets the preset condition. At this point, the second conversion strategy is adopted to convert the target type data values ​​corresponding to the first data values ​​that meet the preset conditions in the same position in the first CPLC data to lowercase letters. Specifically, the target type data value "b" corresponding to the first data value 6 in the same position in the first CPLC data is converted to the uppercase letter "B", and the target type data value "f" corresponding to the first data value 8 in the same position in the first CPLC data is converted to the uppercase letter "F". In this way, the second CPLC data can be obtained.

[0142] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0143] Step 205: Send the second CPLC data and the information of the first conversion strategy to the second terminal.

[0144] After obtaining the second CPLC data, the second CPLC data and the information of the first conversion strategy are sent to the second terminal. This allows the second terminal to perform data verification on the second CPLC data according to the first conversion strategy when using the second CPLC data, thereby determining the integrity of the second CPLC data received by the second terminal and avoiding the use of incorrect CPLC data, which could affect the user's normal work.

[0145] As an optional embodiment, the target data value provided in this embodiment is a letter-type data value contained in the target data value. The target data value is a continuous data value of a preset data length in the initial CPLC data, and the preset data length is not greater than the data length of the initial CPLC data.

[0146] In one scenario, the preset data length provided in this embodiment can be equal to the data length of the initial CPLC data. Thus, the target type data value provided in this embodiment is the sum of all target type data values ​​contained in the initial CPLC data. For example, the initial CPLC data provided in this embodiment can be:

[0147] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0148] The target type data values ​​provided in this embodiment include “F”, “B”, “D”, and “F”.

[0149] In another case, the preset data length provided in this embodiment can be 1 / 3 of the data length of the initial CPLC data, and the continuous data value corresponding to this 1 / 3 can be a continuous data value at any position in the initial CPLC data. For example, the continuous data value corresponding to this 1 / 3 can be a continuous data value calculated starting from the first data value of the initial CPLC data, or it can be a continuous data value calculated starting from the second data value of the initial CPLC data. As long as the position corresponding to the continuous data value of this 1 / 3 is in the initial CPLC data, no specific limitation is made here.

[0150] For example, the initial CPLC data provided in this embodiment may be:

[0151] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0152] The preset data length provided in this embodiment, that is, the continuous data value corresponding to 1 / 3, can be a continuous data value calculated starting from the first data value of the initial CPLC data. That is, the target type data value is determined only from the first 28 data values ​​(479007644701F35606009174091) of the initial CPLC data. Therefore, the target type data value provided in this embodiment is only "F".

[0153] In other cases, the preset data length provided in this embodiment can be 1 / 2 of the data length of the initial CPLC data, and the continuous data value corresponding to 1 / 2 can be a continuous data value at any position in the initial CPLC data. For example, the continuous data value corresponding to 1 / 2 can be a continuous data value calculated starting from the first data value of the initial CPLC data, or it can be a continuous data value calculated starting from the forty-second data value of the initial CPLC data. As long as the position corresponding to the continuous data value of 1 / 2 is in the initial CPLC data, no specific limitation is made here.

[0154] For example, the initial CPLC data provided in this embodiment may be:

[0155] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0156] The preset data length provided in this embodiment, that is, the continuous data value corresponding to 1 / 2, can be a continuous data value calculated starting from the 42nd data value of the initial CPLC data. That is, the target type data value is determined only from the last 42 data values ​​(000005100000449483BDF5380010000000000354647) of the initial CPLC data. Therefore, the target type data values ​​provided in this embodiment include "B", "D" and "F".

[0157] It should be noted that the preset data length provided in this embodiment is not limited to 1 / 3 or 1 / 2 of the initial CPLC data length, but can also be other values, which will not be listed here.

[0158] Thus, this embodiment of the invention can perform encoding operations only on continuous data values ​​of a preset data length in the initial CPLC data, thereby achieving character conversion processing only on target type data values ​​within the preset data length of continuous data values ​​in the initial CPLC data, further improving the security and reliability of the encoded second CPLC data. For a detailed process of encoding continuous data values ​​of a preset data length in the initial CPLC data, please refer to the above embodiment of encoding the initial CPLC data; it will not be repeated here.

[0159] Specifically, when the first terminal 10 encodes only the continuous data values ​​of the preset data length in the initial CPLC data to obtain the second CPLC data and sends the second CPLC data to the second terminal 20, the second terminal 10 also performs data verification processing only on the continuous data values ​​of the preset data length in the received second CPLC data, thereby achieving the purpose of data verification of the received CPLC data and avoiding the use of incorrect CPLC data, which would affect the normal work of the user.

[0160] At this point, the first terminal 10 has completed the encoding process of the initial CPLC data.

[0161] The above embodiments mainly describe the technical solution of applying the data processing method provided in this embodiment to the first terminal 10, that is, the encoding process of the initial CPLC data. The following will describe in detail the technical solution of applying the data processing method provided in this embodiment to the second terminal 20, that is, the data verification process of the second terminal 20 before using or transmitting the received second CPLC data.

[0162] Please see Figure 5 , Figure 5 This is another schematic flowchart of the data processing method provided in the embodiments of the present invention, such as... Figure 5 As shown, the data processing method provided in this embodiment includes steps 501 to 504;

[0163] Step 501: Receive the second CPLC data and the information of the first conversion strategy sent by the first terminal.

[0164] In this embodiment, upon receiving the second CPLC data and the first conversion strategy information sent by the first terminal, the embodiment can perform data verification on the received second CPLC data using the second CPLC data and the first conversion strategy, thereby avoiding the use of incorrect second CPLC data and affecting the user's normal work. The specific data verification process is detailed in steps 502 to 504.

[0165] Step 502: According to the first conversion strategy, perform character conversion processing on the target type data value in the second CPLC data to obtain the third CPLC data.

[0166] In this embodiment, the target type is letter type. The first conversion strategy provided in this embodiment is the first conversion strategy used by the first terminal 10. This first conversion strategy is mainly used to perform character conversion processing on letter type data values ​​in CPLC data.

[0167] In this embodiment, the target type data value in the second CPLC data received by the second terminal 20 is converted into character by using the first conversion strategy used by the first terminal 10. This converts the second CPLC data into the first CPLC data after the first terminal 10 preprocesses the initial CPLC data. This facilitates the subsequent use of the third CPLC data obtained after the second CPLC data has undergone character conversion processing by the first conversion strategy, i.e., the hash value of the first CPLC data after the first terminal 10 preprocesses the initial CPLC data, to verify the second CPLC data, thereby achieving the purpose of verifying the received second CPLC data.

[0168] As an optional embodiment, since the first terminal 10 provided in this embodiment can only perform encoding operations on continuous data values ​​of a preset data length in the initial CPLC data, thereby realizing character conversion processing only on the target type data values ​​among the continuous data values ​​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 character conversion processing before performing data verification on the second CPLC data. Specifically, the step of performing character conversion processing on the target type data values ​​in the second CPLC data to obtain the third CPLC data according to the first conversion strategy can be: obtaining the target data length of the second CPLC data after character conversion processing in the first terminal, and performing character conversion processing on the target type data values ​​among the data values ​​contained within the target data length in the second CPLC data according to the first conversion strategy to obtain the third CPLC data.

[0169] It should be noted that the target data length provided in this embodiment is the preset data length for encoding operations in the first terminal 10. Therefore, the target data length is the same as the preset data length. Thus, the target data length provided in this embodiment can be the same as the data length of the second CPLC data, or it can be any value such as 1 / 3 or 1 / 2 of the data length of the second CPLC data. As long as the target data length is the same as the preset data length, and the position of the continuous data value within the target data length in the second CPLC data is the same as the position of the continuous data value within the preset data length for character conversion processing in the first terminal 10 in the initial CPLC data, no specific limitation is made here.

[0170] In one implementation, the first conversion strategy includes a strategy to convert letter-type data values ​​to uppercase letters. Then, according to the first conversion strategy, the step of performing character conversion processing on the target-type data values ​​contained in the target data length of the second CPLC data to obtain the third CPLC data can be: according to the first conversion strategy, converting the letters in the target-type data values ​​contained in the target data length of the second CPLC data to uppercase letters to obtain the third CPLC data.

[0171] For example, the target data length provided in this embodiment can be the same as the data length of the second CPLC data. The second CPLC data provided in this embodiment can be:

[0172] 479007644701F3560600917409140030136748100000005100000449483bDf5380010000000000354647

[0173] The third CPLC data obtained after the second CPLC data undergoes character conversion processing using the first conversion strategy is:

[0174] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0175] In this embodiment, the four letter data values ​​"F", "b", "D" and "f" in the second CPLC data are converted into characters to obtain "F", "B", "D" and "F".

[0176] In another implementation, the first conversion strategy includes a strategy to convert letter-type data values ​​to lowercase letters. Then, according to the first conversion strategy, the step of performing character conversion processing on the target-type data values ​​contained in the target data length of the second CPLC data to obtain the third CPLC data can be: according to the first conversion strategy, converting the letters in the target-type data values ​​contained in the target data length of the second CPLC data to lowercase letters to obtain the third CPLC data.

[0177] For example, the target data length provided in this embodiment can be the same as the data length of the second CPLC data. The second CPLC data provided in this embodiment can be:

[0178] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0179] The third CPLC data obtained after the second CPLC data undergoes character conversion processing using the first conversion strategy is:

[0180] 479007644701f3560600917409140030136748100000005100000449483bdf5380010000000000354647

[0181] In this embodiment, the four letter data values ​​"F", "B", "D" and "F" in the second CPLC data are converted into characters to obtain "f", "b", "d" and "f".

[0182] Step 503: Perform a hash operation on the third CPLC data to obtain the second hash value.

[0183] In this embodiment, the SHA secure hash algorithm used in the hash operation process provided in this embodiment can be the SHA384 algorithm.

[0184] For example, the third CPLC data provided in this embodiment may be:

[0185] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0186] The process of using the SHA384 algorithm to hash the third CPLC data to obtain the second hash value can be as follows:

[0187] SHA384(479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647)

[0188] =>

[0189] 14d2fd9806bfdcdd291a859dfff7ea0cdfcd77adfa1ea86b723e223d8b96c8cd243f848c2db4468f2ba34ddf03470a26

[0190] Step 504: Determine the integrity of the second CPLC data based on the second hash value.

[0191] In this embodiment, the integrity of the second CPLC data is determined based on the uniqueness of the hash value obtained through hash operation. Specifically, if the second CPLC data obtained by the second terminal 20 is correct and complete, the third CPLC data obtained by performing character conversion processing corresponding to the first conversion strategy on the second CPLC should be the same as the first CPLC data obtained by the first terminal 10 after preprocessing the initial CPLC. However, since the second terminal 20 cannot know whether the third CPLC data is the same as the first CPLC data obtained by the first terminal 10, this embodiment determines the integrity of the second CPLC data received by the second terminal 20 by using the characteristic that the hash values ​​corresponding to the same data are the same, and by using the hash value of the first CPLC data and the second conversion strategy (a strategy opposite to the first conversion strategy) to perform character conversion processing on the target type data value in the first CPLC data.

[0192] As an optional embodiment, this embodiment determines whether the data value of the target type in the second CPLC data has undergone character conversion processing of the second conversion strategy in the first terminal 10 based on the data value at the same position in the second hash value as the data value of the target type in the second CPLC data, thereby judging the correctness of the data value of the target type in the second CPLC. That is, this embodiment judges the correctness of the data value of the target type in the second CPLC by determining whether the uppercase and lowercase format of the target value in the second CPLC data and the data value at the corresponding position in the second hash value meet preset conditions. Thus, the data value of the target type in the second CPLC data provided in this embodiment is equivalent to a check code that can be used for data verification processing, which can be used for data verification of the second CPLC data, thereby effectively improving the reliability and security of the CPLC data and preventing the second terminal 20 from using incorrect or incomplete second CPLC data, which would affect the normal operation of the second terminal 20.

[0193] In some embodiments, see Figure 6 , Figure 6 This is a flowchart illustrating a data verification process provided in an embodiment of the present invention, such as... Figure 6 As shown, steps 5041 to 5043 are included;

[0194] Step 5041: Determine the second target position in the second CPLC data for the target type data value.

[0195] For example, the second CPLC data provided in this embodiment may be:

[0196] 479007644701F3560600917409140030136748100000005100000449483bDf5380010000000000354647

[0197] Then the second target position of the target type data value (letter type data value) in the second CPLC data can be determined. Specifically, the second target position of the target type data value "F" in the second CPLC data is the position of the 13th data value, the second target position of the target type data value "b" in the second CPLC data is the position of the 60th data value, the second target position of the target type data value "D" in the second CPLC data is the position of the 61st data value, and the second target position of the target type data value "f" in the second CPLC data is the position of the 62nd data value.

[0198] Step 5042: Determine the second data value at the second target position in the second hash value.

[0199] For example, the second hash value corresponding to the third CPLC data provided in the above embodiments is:

[0200] 14d2fd9806bfdcdd291a859dfff7ea0cdfcd77adfa1ea86b723e223d8b96c8cd243f848c2db4468f2ba34ddf03470a26

[0201] Then the second data value at the second target position in the second hash value can be determined. Specifically, when the second target position is the 13th data value, the second data value is d; when the second target position is the 60th data value, the second data value is 6; when the second target position is the 61st data value, the second data value is c; and when the second target position is the 62nd data value, the second data value is 8.

[0202] Step 5043: If the second data value meets the preset conditions and the size format of the letters in the target type data value is not the target format, then the second CPLC data is determined to be complete data.

[0203] In this embodiment, the target format is the size format of the letters in the target type data value after character conversion processing by the first conversion strategy. 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 size relationship between the second data value and the preset threshold. Specifically, in one case, the preset condition provided in this embodiment can be that the second data value is not greater than the preset threshold; in another case, the preset condition provided in this embodiment can be that the second data value is greater than the preset threshold. Since the CPLC data provided in this embodiment is composed of hexadecimal data, the preset threshold provided in this embodiment can be 6, 7, etc. This embodiment does not limit the preset threshold; as long as it is a hexadecimal data value, that is, a data value among 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f, it is acceptable.

[0204] In one implementation, the first conversion strategy adopted in this embodiment can be a strategy of converting letter-type data values ​​to uppercase letters. In this embodiment, the target format is uppercase. That is, the second CPLC data can only be determined to be complete data when the second data value meets the preset conditions and the letter size format in the target type data value is not uppercase.

[0205] Specifically, the preset threshold used in this embodiment can be 8, and the preset condition used in this embodiment can be that the second data value is not greater than the preset threshold 8. For example, the second CPLC data used in this embodiment can be:

[0206] 479007644701F3560600917409140030136748100000005100000449483bDf5380010000000000354647

[0207] The third CPLC data is:

[0208] 479007644701F3560600917409140030136748100000005100000449483BDF5380010000000000354647

[0209] The second hash value corresponding to the third CPLC data is:

[0210] 14d2fd9806bfdcdd291a859dfff7ea0cdfcd77adfa1ea86b723e223d8b96c8cd243f848c2db4468f2ba34ddf03470a26

[0211] Therefore, the second data values ​​can be determined as d, 6, c, and 8. Thus, it can be determined that the second data value d does not meet the preset condition, the second data value 6 meets the preset condition, the second data value c does not meet the preset condition, and the second data value 8 meets the preset condition.

[0212] Since this embodiment determines the second CPLC data to be complete only when the second data value meets the preset conditions and the letter size format in the target type data value is not the target format, that is, this embodiment can determine the second CPLC data to be complete only when the second data value is not greater than the preset threshold 8 and the letter size format in the target type data value is not uppercase. Therefore, the data verification method provided in this embodiment is as follows: if the second data value d does not meet the preset conditions, then the second data value d corresponds to the target type data value "F" in the second CPLC data and should be in uppercase; if the second data value 6 meets the preset conditions, then the second data value 6 corresponds to the target type data value "b" in the second CPLC data and should not be in uppercase, but should be in lowercase; if the second data value c does not meet the preset conditions, then the second data value c corresponds to the target type data value "D" in the second CPLC data and should be in uppercase; if the second data value 8 meets the preset conditions, then the second data value 8 corresponds to the target type data value "f" in the second CPLC data and should not be in uppercase, but should be in lowercase.

[0213] Based on the specific data verification process provided in the above embodiments, it can be seen that the size and format of the target type data value in the second CPLC data provided in this embodiment have passed the data verification. Therefore, it can be determined that the second CPLC data provided in this embodiment is complete.

[0214] In another implementation, the first conversion strategy can also be a strategy of converting letter-type data values ​​to lowercase letters. Therefore, the target format provided in this embodiment is lowercase. That is, the second CPLC data can only be determined to be complete data when the second data value meets the preset conditions and the letter format in the target type data value is not lowercase. For the specific data verification process, please refer to the method provided in the above embodiments, which will not be repeated here.

[0215] At this point, the second terminal 20 has completed the data verification process for the second CPLC data.

[0216] Based on the method described in the above embodiments, this embodiment will be further described from the perspective of a data processing device. The data processing device can be implemented as an independent entity or integrated into an electronic device, such as a terminal, which may include a mobile phone, a tablet computer, etc.

[0217] In some embodiments, this embodiment provides a data processing device applied to a first terminal. For details, please refer to [link to relevant documentation]. Figure 7 , Figure 7 This is a schematic diagram of a data processing device provided in an embodiment of the present invention, such as... Figure 7 As shown, the data processing device 700 provided in this embodiment of the invention includes: an acquisition module 701, a first conversion module 702, a first calculation module 703, a second conversion module 704, and a sending module 705;

[0218] The acquisition module 701 is used to acquire the initial CPLC data to be encoded.

[0219] The initial CPLC data includes at least one data value of letter type.

[0220] The first conversion module 702 is used to perform character conversion processing on the target type data value in the initial CPLC data using a preset first conversion strategy to obtain the first CPLC data.

[0221] The target type is a letter type.

[0222] In one implementation, the first conversion strategy includes a strategy to convert letter-type data values ​​to uppercase letters. The first conversion module 702 is specifically used to use a preset first conversion strategy to convert target-type data values ​​in the initial CPLC data to uppercase letters to obtain the first CPLC data.

[0223] In another implementation, the first conversion strategy includes a strategy to convert letter-type data values ​​to lowercase letters. The first conversion module 702 is specifically used to use a preset first conversion strategy to convert target-type data values ​​in the initial CPLC data to lowercase letters to obtain the first CPLC data.

[0224] In some embodiments, the target type data value is the letter type data value contained in the target data value, the target data value is a continuous data value of a preset data length in the initial CPLC data, and the preset data length is not greater than the data length of the initial CPLC data.

[0225] The first arithmetic module 703 is used to perform hash operations on the first CPLC data to obtain the first hash value.
