Detailed Description
For external devices such as printing and card making, a matched appointed authentication consumable is usually provided for use, and a user does not want to use a third party consumable or needs to be appointed when performing a special task (for example, special transfer consumable is needed for making an identity card), so that the inventor has known a technology that a consumable identification reader for verifying whether the current consumable is the appointed authentication consumable is arranged in the external device, an authentication chip is arranged in the consumable, and the consumable identification reader in the external device is in communication connection with the authentication chip.
And identifying consumable authentication information in the authentication chip through the consumable identification reader-writer so as to judge whether a user uses the appointed authentication consumable, and stopping the external equipment and prompting the user when the identification or authentication fails.
In most cases, the external device is also connected to the host computer so as to respond to the working instruction of the host computer, such as a printer or a card making machine connected to the computer or the mobile terminal, and the image information to be printed or printed is selected in the application of the host computer, and is printed or printed by the external device.
Referring to fig. 1, in a first embodiment of the present invention, an authentication chip is provided, which can be separately provided for a user to install, so that the user can conveniently upgrade using the existing consumable, or the authentication chip is integrated into the consumable and is not separable, so that the host computer application and the binding sales of the consumable are facilitated.
The authentication chip comprises a chip carrier, a chip read-write interface matched with a consumable identification reader-writer interface is arranged on the chip carrier, if the chip read-write interface is a contact communication interface, the contact position of the chip read-write interface is required to be matched with the consumable identification reader-writer interface, if the chip read-write interface is a non-contact interface (such as an antenna and an RFID), the installation position of the chip read-write interface is required to be matched with the consumable identification reader-writer interface, in one implementation mode, the shape of the chip carrier is also matched with the shape of the consumable identification reader-writer interface, for example, the consumable identification reader-writer interface is annular, and the chip carrier is also annular arranged on the end face of a coiled material.
In addition, the authentication chip is also internally provided with an on-chip operating system (namely a COS system), and in order to operate the system, the authentication chip further comprises a microprocessor and a second storage module, wherein the microprocessor is connected with a chip read-write interface to realize communication connection with a consumable identification reader-writer, the second storage module stores system files of the on-chip operating system, and the microprocessor operates the on-chip operating system by loading the system files in the second storage.
The chip carrier further includes a first storage module, where the first storage module stores at least application authentication information for authenticating an application of the upper computer, and in some cases, the first storage module further stores external device internal authentication information for authenticating an internal application of the external device, that is, consumable identification reader-writer authorizes or unlocks the internal application of the external device through the authentication chip, for example, consumable authentication information for authenticating whether the consumable is a specified consumable, where the consumable authentication information is used to unlock internal function enablement of the external device, for example, after the authentication ribbon is the specified authentication ribbon, the transfer device is allowed to transfer.
Specifically, if the current consumable carrier is used for upgrading, the first storage module only needs to store application authentication information, for example, a user only needs to purchase an authentication chip and install the authentication chip on the consumable carrier (for example, on an empty ribbon holder), and the consumable carrier is installed in an external device to perform authentication.
If the application and the consumable are bound and sold for the upper computer, the first storage module stores application authentication information and consumable authentication information at the same time, and can be used for authenticating appointed consumable and upper computer application respectively, and can also be used for unlocking or authorizing other functions of the application of the external device by integrating other internal authentication information of the external device in the authentication chip.
When the upper computer application needs to be authenticated, the authentication chip receives an application authentication instruction from the consumable identification reader-writer, and the instruction can be initiated by the upper computer through the consumable identification reader-writer in the external device (for example, a user opens the upper computer application or clicks certain non-open functions of the upper computer application), and can also be initiated by the external device to the authentication chip through the consumable identification reader-writer.
After the microprocessor obtains the application authentication instruction through the chip read-write interface, the microprocessor responds to the application authentication instruction to encrypt the application authentication information and generate a first secret code, and the first secret code is sent to the consumable identification reader through the chip read-write interface.
Specifically, an on-chip operating system (COS system) is operated in the authentication chip, and after the COS system obtains an application authentication instruction from the consumable identification reader-writer, data exchange is required between the authentication chip and the consumable identification reader-writer, and a communication handshake relationship is established, that is, the consumable identification reader-writer needs to be mutually authenticated with the authentication chip to confirm and verify identities of both sides, and then further data transmission can be arranged. The authentication method is the prior art, for example, authentication is performed by means of mutual MAC address, random code, etc., and will not be described in detail here.
Specifically, in order to prevent illegal interception of the authentication information, the authentication chip needs to encrypt the application authentication information before sending the application authentication information to the consumable identification reader-writer. The transmission data encryption mode of the specific COS system also belongs to the prior art, for example, through DES encryption operation and the like.
The key used for encryption can also be obtained in various ways, for example, the key is generated by accessing a codebook stored in the second memory and is encrypted to generate a first secret code, the first secret code and the encrypted key are sent to an upper computer or a consumable identification reader-writer, the key is obtained through decryption by a preset decryption rule, and then the first secret code is decrypted, so that the application authentication information is obtained.

Because the data encryption mode of the COS system is mature, details are not described here.
When the consumable is required to be authenticated, the microprocessor acquires a consumable authentication instruction from the consumable identification reader through the chip read-write interface, encrypts the consumable authentication information and generates a second secret code in response to the consumable authentication instruction, and sends the second secret code to the consumable identification reader through the chip read-write interface. The handshake establishment between the authentication chip and the consumable identification reader-writer, and the encryption mode of consumable authentication information in the authentication chip are consistent with the processing method of application authentication information.
