The control method according to the embodiment of the present invention is further described below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides an automated processing method for production data, which is applied to a data processing device, where the data processing device is in communication connection with a production device, the production device is used for manufacturing a smart IC card, and the automated processing method for production data includes:
step S110, acquiring an initial project data set to be uploaded, wherein the initial project data set comprises a plurality of pieces of initial production data, and the initial project data set carries project identification information;
step S120, a preset data processing script is obtained according to the project identification information, the initial production data is divided into a plurality of data fields through the data processing script, and the encryption attribute of each data field is determined, wherein the data fields are used for indicating the corresponding fields of the IC data in the initial production data;

and step S140, updating the corresponding initial production data into encrypted production data according to the encrypted fields, and uploading an encrypted project data set to the production equipment, wherein the encrypted project data set comprises project identification information, a data processing script and a plurality of pieces of encrypted production data.
It should be noted that the data processing device in this embodiment may be any device that can install data processing software, such as a computer, a development device, and the like, and the data processing software may be connected to the production device and upload data to the production device, and the specific type of the data processing device is not limited in this embodiment. The production equipment can be equipment for manufacturing the intelligent IC card, and after the production data are uploaded to the production equipment, the production equipment can write the production data into the intelligent IC card through the reader-writer, so that personalization of the intelligent IC card is realized.
It should be noted that, in this embodiment, the item identification information is distinguished by the item identification information, the item identification information may be description information of a card making project of an intelligent IC card, for the field of an intelligent IC card, the card making is usually performed by taking an item as a unit, since an item encryption key is generated by the item identification information, in order to ensure privacy of the item encryption key, multiple pieces of production data of each initial item data set may belong to the same card making project of the same customer, for example, a bank card is taken as an example, one item may be a card making project of a class B card of an a bank, and may also be a card making project of other fields (e.g., public transportation, social security, etc.), on this basis, the item identification information may include identification information of the bank a and identification information of the class B card, and different card making projects may be distinguished.
The production data may be obtained by IC data conversion, or may be directly imported into the data processing device through an external device, which is not limited herein.
In order to split and identify the production data, the data processing script is set in the data processing device in advance, and the processing of the production data is automatically executed through the data processing script. It should be noted that, because different production data have different formats, different data processing scripts need to be set for different production data, and in order to match the corresponding data processing scripts accurately, this embodiment may associate the project identification information with the data processing scripts, so as to ensure that the obtained data processing scripts can correctly process the initial production data in the initial project data set. It can be understood that the data processing script may write tag field information and field attributes for the corresponding initial production data, so that the data processing script may map a data field corresponding to each IC data from a code of the production data, and establish the field attribute corresponding to the field, so as to provide a data basis for the subsequent encryption processing.
It should be noted that, because the production data is obtained by converting the IC data, one production data may include multiple IC data, for example, the IC data of the bank card includes a user name, a card type, a contact manner, an account password, and the like, and after the production data is obtained by conversion, a code of the production data includes each of the IC data, in this embodiment, a data field corresponding to each of the IC data can be split from the production data by using a data processing script, and because whether the IC data is sensitive information is known in advance and can be set, an encryption attribute can be set for each data field, so as to determine whether the data field needs to be encrypted, for example, in the IC data of the bank, the user name, the contact manner, and the account password belong to sensitive information and need to be encrypted, and the card type does not belong to sensitive information and does not need to be encrypted, and by configuring the encryption attribute of each data field in advance in the data processing script, the data field can be determined quickly, and the data processing efficiency is improved. It will be appreciated that the encryption attribute may be in any form capable of characterizing the need for encryption or the lack thereof.
It should be noted that the item identification information of this embodiment is used to represent different card making items, so that the item identification information corresponding to different card making items is different, in order to improve data security, an MD5 value may be calculated according to the item identification information, the calculated MD5 value is used as an item encryption key, and a data field to be encrypted is encrypted to obtain an encrypted field. It can be understood that the calculation method of the MD5 value is a technique well known to those skilled in the art, and this embodiment does not relate to the improvement of the MD5 algorithm, and therefore is not described herein in detail.
It should be noted that after the encrypted field is obtained, the corresponding data field in the initial production data can be replaced by the encrypted field, so that the encrypted production data is obtained, the sensitive information in the encrypted production data can be encrypted, the data security is improved, the encryption process is automatically executed by the data processing script, manual intervention is not needed, and the labor cost is reduced.
It should be noted that, after each piece of initial production data of the initial project data set is encrypted, the encrypted project data set is obtained and automatically uploaded to the production equipment to manufacture the smart IC card. It can be understood that, because the encrypted production data in the encrypted project data set contains the encrypted fields, the production equipment can decrypt the encrypted production data according to the same principle, for example, the MD5 value is calculated as the decryption key according to the project identification information obtained by indexing, the encrypted fields are decrypted according to the decryption key to obtain the initial data fields, and then the initial production data are spliced and written into the smart IC card to realize the personalization of the card, so that the production data automatically run in the whole card making process, and the labor cost is effectively saved.
It should be noted that, when uploading the encrypted project data set, the description information, version number, and the like of the data processing software may be uploaded at the same time, and the uploading is not limited to the production data, and may also be performed to upload other information related to the analysis and decryption of the production data, and is not limited in many cases.
In addition, in an embodiment, the data processing script configures a plurality of tag field information in advance, where the tag field information is used to indicate the IC data, and the tag field information is associated with an encryption attribute and a type attribute, referring to fig. 2, step S120 in the embodiment shown in fig. 1 further includes, but is not limited to, the following steps:
step S210, determining data fields corresponding to the information of each label field in the initial production data through a data processing script;
step S220, based on the mapping relation between the label field information and the data field, determining the encryption attribute and the type attribute of the data field;
and step S230, verifying the validity of the data for each data field based on the type attribute.
It should be noted that, the data processing script may be configured with a plurality of tag field information in advance, and each tag field information represents one IC data, so that each data field can be quickly identified from the production data when the data processing script runs, and the data processing efficiency is improved.
It should be noted that, in order to distinguish different data fields, an encryption attribute and a type attribute associated with tag field information may be preset in the data processing script, and after the data fields are split, the corresponding encryption attribute and type attribute are established, so as to improve the data processing efficiency.
It should be noted that the type attribute may be used to characterize the data type of the data field, such as the user name and the contact information described above, and after the type attribute is obtained, the data validity of the data field may be verified, for example, whether user information exists, whether the data field is matched with a field of actual production data, whether the field value length is smaller than the actual length, and the index tag does not exist, and the verification method of the data validity may be determined according to the specific type of the data field.
In addition, in an embodiment, the encryption algorithm is a 3DES algorithm, and referring to fig. 3, after step S130 of the embodiment shown in fig. 1 is executed, the following steps are included, but not limited to:
step S310, determining the length of an initial field of an encrypted field;
step S320, when the length of the initial field is not a multiple of eight, zero padding is carried out on the encrypted field so as to adjust the length of the field of the encrypted field to be a multiple of eight;
in step S330, a length description field is added before the encrypted field, and the length description field is used for describing the initial field length of the encrypted field.
It should be noted that a specific Algorithm of the 3DES Algorithm (Triple Data Encryption Algorithm) is a technique well known to those skilled in the art, and is not described herein again. Because the lengths of the data fields are different, the initial field lengths of the encrypted fields obtained by encrypting through the 3DES are also different, in order to facilitate updating to production data, the data length needs to be ensured to be multiple of 8, after the encrypted fields are obtained, if the initial field lengths are multiple of 8, the encrypted fields can be directly used, otherwise, the encrypted fields are subjected to zero padding to enable the field lengths to reach multiple of 8, such as 8 bits, 16 bits and the like.
It should be noted that, because the encrypted field has the possibility of zero padding, in order to determine the actual field length of the encrypted field during decryption, in this embodiment, a length description field is added before the encrypted field, for example, a 4-bit hexadecimal value represents a natural number, the length of the initial field of the encrypted field is identified by the natural number, and after the length of the initial field is determined according to the length description field during decryption, the zero padding position is removed from the encrypted field, so that an actual plaintext value can be obtained.
In addition, in an embodiment, referring to fig. 4, before executing step S140 of the embodiment shown in fig. 1, the following steps are further included, but not limited to:
step S410, determining an MD5 value of initial production data;
step S420, determining the MD5 value of the data processing script;
step S430, add the MD5 value of the initial production data and the MD5 value of the data processing script to the encrypted item data set.
It should be noted that, the MD5 value is calculated for the initial production data and the data processing script, and the data is associated with the encrypted project data set, so that the data can be verified during decryption, for example, after the encrypted project data set is uploaded to the production equipment, the production equipment obtains the target production data from the encrypted project data set, and when the MD5 value of the calculated target production data is the same as the MD5 value of the initial production data, it can be determined that the decryption of the initial production data is completed and the data is consistent, so that the subsequent smart IC card manufacturing can be performed.
It can be understood that the data processing script is the same, after the production equipment obtains the corresponding data processing script according to the production identification information carried in the production instruction, when the MD5 value calculated according to the data processing script is the same as the MD5 value of the data processing script of the encrypted project data set, it can be determined that the data processing script is correct, and decryption operation can be performed by using the data processing script.
In addition, in an embodiment, referring to fig. 5, before executing the step S430 of the embodiment shown in fig. 4, the following steps are included, but not limited to:
step S510, determining package printing data, SMC chip data and data layout information corresponding to each initial production data according to the item identification information;
step S520, generating CRC of package printing data and CRC of SMC chip data;
step S530, the CRC of the package print data, the CRC of the SMC chip data, and the data layout information are associated to the encrypted production data.
The package print data is data that is not written to the smart IC card and is used for printing, for example, contents in a letter attached when a credit card issues a card; in order to ensure that production data can verify relevant data, after package print data and SMC chip data of each production data are determined according to item identification information, cyclic Redundancy Check (CRC) is generated for the package print data and the SMC chip data, and verification of the package print data and the SMC chip data is realized by production equipment through CRC, so that validity of the data is ensured.
The data layout information may be layout information related to a card surface of the smart IC card, for example, description information representing a layout of a credit card level, and different levels of the credit card are distinguished by different description information. The data layout information is associated in the encrypted production data, so that after the target production data is obtained by the production equipment, whether the decryption of the data is correct or not can be determined according to the data layout information, and the data layout information can also be used for indexing the production data, so that the production data obtained by the production equipment is ensured to be in accordance with the initial production data.
In addition, referring to fig. 6, fig. 6 is a flowchart of an automated processing method for production data, the method being applied to a production device, the production device being used for manufacturing a smart IC card, the production device being in communication connection with a data processing device, the automated processing method for production data according to an embodiment of the present invention includes:
step S610, acquiring a production instruction, wherein the production instruction comprises production identification information and index information;
step S620, determining a target project data set from a plurality of encrypted project data sets according to production identification information, wherein the production identification information matches the project identification information of the target project data set, and the encrypted project data set is obtained by the automated processing method of production data according to the embodiment shown in fig. 1;
step S630, obtaining target production data from a plurality of encrypted production data of the target project data set according to the index information;
step S640, determining a project decryption key according to the production identification information, decrypting encrypted fields in the target production data through the project decryption key, splicing a plurality of data fields corresponding to the target production data into initial production data through a data processing script, wherein the project decryption key is an MD5 value obtained according to the production identification information;
step S650, manufacturing of the intelligent IC card is executed according to the initial production data, and when a delivery instruction aiming at the target item data set is obtained, the target item data set is deleted.
It should be noted that, the production equipment may store a plurality of encrypted item data sets, and based on this, a target item data set whose item identification information is the same as the production identification information may be matched from the encrypted item data sets through the production identification information carried in the production instruction, for example, the production identification information and the item identification information are ID numbers or batch numbers of card-making items, which is not limited herein.
It should be noted that, each time the production equipment produces the card, the production equipment can execute the card production according to the same type of production data, for example, the production data with the same data layout information, and the production data required by the secondary production can be accurately retrieved from the encrypted item data set by introducing the index information, so that the card production efficiency is improved.
It should be noted that the encrypted fields in the encrypted production data are obtained by encrypting according to the item encryption key, and the item encryption key is obtained by using the MD5 value of the item identification information, and since the production identification information is the same as the item identification information, the item decryption key can be obtained according to the MD5 value that generates the identification information, so that the encrypted fields are decrypted and then spliced into the initial production data through the data processing script.
It should be noted that when the shipping instruction is obtained, it may be determined that all the target production data of the target item data set is used for card making, and at this time, the target item data set may be deleted, so as to improve the security of the data.
In addition, in an embodiment, the encrypted production data further includes CRC of the package printing data, CRC of the SMC chip data, and data layout information, and the index information is target layout information, and referring to fig. 7, the method further includes, but is not limited to, the following steps:

and step S730, after the initial production data are spliced, determining a check MD5 value of the spliced initial production data, and performing data check according to the check MD5 value and the MD5 value of the initial production data in the encrypted project data set.
It should be noted that, when the production data of the target project data set is more, the production equipment needs to select part of the production data as the production data of the current batch, so that the target production data can be determined by indexing according to the target layout information, so that the layout information of the smart IC cards produced in each batch is the same, and the production efficiency is improved.
It should be noted that the use and principle of the CRC of the package print data, the CRC of the SMC chip data, and the data layout information may refer to the description of the embodiment shown in fig. 5, and are not repeated herein, and the CRC obtained according to the production identification information is used as a CRC check value to perform integrity verification on the package print data and the SMC chip data, so that the accuracy of the data is ensured, manual checking is not required, and the labor cost is reduced.
It should be noted that after the initial production data is obtained by splicing the decrypted data fields, when the check MD5 value of the initial production data is the same as the MD5 value of the same initial production data carried by the encrypted item data set, it may be determined that the spliced data is consistent with the original data, and the accuracy of the data is ensured.
