[0078] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0079] In existing technologies, IC card data is generally stored in the hardware abstraction layer of the IC card chip and has a high level of security permissions, preventing users from reading or writing data; moreover, existing IC cards do not record information about the IC card manufacturing process, such as IC card manufacturer information, making it impossible to trace and statistically analyze IC cards.

[0080] Therefore, an information storage and retrieval method is needed to write information from the IC card manufacturing process into the IC card chip, and to read information from the IC card chip from the IC card manufacturing process, so as to statistically analyze IC cards with consistent data and to trace IC card data.

[0081] Figure 1 An exemplary system architecture applicable to an embodiment of the present invention is shown, which includes a card writing device 110, an IC card 120, and a card reading device 130.

[0082] The card writing device 110 is used to write the data to be written into the security domain corresponding to the security domain identifier of the IC card 120 according to the write command after the operator's authentication identifier is passed.

[0083] IC card 120 includes an IC card chip located inside the card body. The IC card chip is used to store a security domain identifier and the encryption algorithm and IC card data corresponding to the security domain identifier.

[0084] The card reader 130 is used to read the security domain identifier of the IC card and the encryption algorithm corresponding to the security domain identifier; and to authenticate the operator's authentication identifier; after confirming that the operator has been authenticated, it reads the IC card data in the security domain corresponding to the security domain identifier according to the read command.

[0085] It should be noted that the above Figure 1 The structure shown is merely an example, and the embodiments of the present invention are not limited thereto.

[0086] Based on the above description Figure 2 An exemplary flowchart of an information storage method provided by an embodiment of the present invention is shown, which can be executed by an information storage device.

[0087] like Figure 2 As shown, the process includes:

[0088] Step 210: The card writing device reads the security domain identifier of the IC card.

[0089] In this embodiment of the invention, the security domain identifier of the IC card also corresponds to an encryption algorithm, which is used to authenticate the authentication identifier.

[0090] Step 220: The card writing device obtains the operator's authentication identifier and determines whether the operator has been successfully authenticated based on the authentication identifier.

[0091] In this embodiment of the invention, the operator's authentication is determined by the security domain identifier and the encryption algorithm corresponding to the security domain identifier.

[0092] Step 230: After confirming that the operator has been authenticated, the card writing device writes the data to be written into the security domain corresponding to the security domain identifier of the IC card according to the write command.

[0093] In this embodiment of the invention, the data to be written includes at least one of the following:

[0094] The IC card's chip information, the IC card's operating system information, and the IC card's application information.

[0095] In step 210, before the card writing device reads the security domain identifier of the IC card, the card writing device initializes and resets the IC card according to the reset command, thereby preventing errors in the data to be written to the IC card.

[0096] In step 220, the card writing device determines whether the operator has been successfully authenticated by using the security domain identifier and the corresponding encryption algorithm. Specifically, the card writing device reads the encryption algorithm corresponding to the security domain identifier of the IC card; the card writing device determines whether the operator has been successfully authenticated based on the operator's authentication identifier and the encryption algorithm corresponding to the security domain identifier.

[0097] In step 230, the IC card chip information includes at least one of the following: IC card chip manufacturer information, IC card chip model information, IC card chip production date, IC card chip serial number, IC card chip batch number, IC card chip module manufacturer information, and IC card chip module packaging date; the IC card operating system information includes at least one of the following: operating system manufacturer information, operating system version information, and operating system release date; the IC card application information includes at least one of the following: IC card manufacturer information, IC card production date, IC card data writer information, IC card data writing date, and IC card data writing device identifier.

[0098] Furthermore, Table 1 below provides an example of the chip information for the IC card, as shown in Table 1 below.

[0099] Table 1

[0100]

[0101]

[0102] Table 2 below provides an example of the operating system information for the IC card, as shown in Table 2 below.

[0103] Table 2

[0104]

[0105] Table 3 below provides an example of IC card application information, as shown in Table 3 below.

[0106] Table 3

[0107]

[0108] In one feasible approach, the data to be written can be written to the IC card using a script customized by the IC card manufacturer.

[0109] In this embodiment of the invention, the write command is an APDU command; the card writing device converts the data to be written into a binary string; the binary string is used to represent the data to be written; the card writing device writes the binary string into the security field corresponding to the security field identifier of the IC card according to the APDU command.

[0110] After writing the data to be written into the security domain corresponding to the security domain identifier of the IC card, a custom tag is added to the data to be written; the custom tag is used to index the data to be written.

[0111] To better illustrate the above storage information technology solutions, Figure 3 An exemplary schematic diagram of an information storage process is shown, such as... Figure 3 As shown, the process is as follows:

[0112] Step 310: The card writing device obtains a reset command.

[0113] The reset command can be entered by the operator on the card writing device, or it can be preset on the card writing device and selected by the operator. For example, the reset command is: "Reset SmartCard". After the card writing device successfully initializes and resets the IC card, it will send a success indication.

[0114] Step 320: The card writing device reads the security domain of the IC card.

[0115] After the IC card initialization and reset is successful, the card writing device can display the IC card's security domains (there can be multiple security domains, and the number is not limited here) to the operator for selection; or the operator can directly write the security domain address into the card writing device; for example, if the operator selects the nth security domain, the 5-byte instruction corresponding to the nth security domain is "00A4 400 00". When the card writing device accesses the IC card and determines that the nth security domain corresponding to "00A4 400 00" can be written with data, it returns a success indication (such as returning the byte "9000").

[0116] Step 330: The card writing device performs external authentication.

[0117] The operator enters the authentication identifier of the external GP authentication (such as "8050 0000 08", "80500000 08", etc.) on the card writing device. The card writing device verifies the authentication identifier of the external GP authentication through the encryption algorithm corresponding to the nth security domain. If the verification is successful, the operator is allowed to write data.

[0118] Step 340: The card writing device writes the data to be written.

[0119] After the authentication identifier of the external GP authentication is verified, the card writing device writes the binary string (e.g., "008C00F……8653") corresponding to the data to be written into the nth security field according to the 5-byte APDU instruction (e.g., "80E29F7F 2A"). It also sets the label of the data to be written according to the custom label defined by the operator (e.g., label is x1, x2, etc.), and then returns a success indication (e.g., return byte "9000") after the writing is successful.

[0120] Figure 4 This is a schematic flowchart illustrating an information reading method exemplarily shown in an embodiment of the present invention, such as... Figure 4 As shown, the process includes:

[0121] Step 410: The card reader reads the security domain identifier of the IC card and the encryption algorithm corresponding to the security domain identifier.

[0122] Step 420: The card reader obtains the operator's authentication identifier and determines whether the operator has been successfully authenticated based on the encryption algorithm corresponding to the operator's authentication identifier and the security domain identifier.

[0123] Step 430: After confirming that the operator has been authenticated, the card reader reads the IC card data in the security domain corresponding to the security domain identifier according to the read command.

[0124] In this embodiment of the invention, the IC card data includes at least one of the following information:

[0125] IC card chip information, IC card operating system information, IC card application information.

[0126] Furthermore, the IC card's chip information includes at least one of the following: IC card chip manufacturer information, IC card chip model information, IC card chip production date, IC card chip serial number, IC card chip batch number, IC card chip module manufacturer information, and IC card chip module packaging date; the IC card's operating system information includes at least one of the following: operating system manufacturer information, operating system version information, and operating system release date; the IC card's application information includes at least one of the following: IC card manufacturer information, IC card production date, IC card data writer information, IC card data writing date, and IC card data writing device identifier.

[0127] In other words, the security domain of the IC card records at least one piece of data from Tables 1, 2, and 3 above.

[0128] To better illustrate the technical solution for reading information described above Figure 5 An exemplary schematic diagram of an information reading process is shown, such as... Figure 5 As shown, the process is as follows:

[0129] Step 510: The card reader reads the security domain of the IC card.

[0130] The card reader can display the security domains of the IC card to the operator for selection. After the operator selects the nth security domain, the 5-byte instruction corresponding to the nth security domain, "00A4 400 00", is verified. When it is determined that the nth security domain corresponding to "00A4 400 00" can read data, a success indication is returned (such as the returned byte "9000").

[0131] Step 520: The card reader performs external authentication.

[0132] The operator enters the authentication identifier of the external GP authentication (such as "8050 0000 08", "80500000 08", etc.) on the card reader. The card reader verifies the authentication identifier of the external GP authentication through the encryption algorithm corresponding to the nth security domain. If the verification is successful, the operator is allowed to read the data.

[0133] Step 530: The card reader reads the IC card data.

[0134] After the authentication identifier of the external GP authentication is verified, the card reader reads the IC card data of the nth security domain according to the APDU instruction (such as "80E2 9F7F2A"), and returns the IC card data after successful reading. The read instruction and the write instruction can be the same, and no specific limitation is made here.

[0135] This invention also provides an IC card, including a card body and an IC card chip located within the card body; wherein the IC card chip is used to record each security domain, the encryption algorithm corresponding to each security domain, and IC card data, so that the operator can read and / or write data to the IC card.
