In a specific application scenario, a detailed process of using the physical electronic card of the present disclosure by a user is described below to more fully show the performance of the physical electronic card of the embodiment of the present disclosure in practical applications.
In one embodiment, the physical electronic card taken by the user is a credit card capable of providing existing credit card services, and the card surface of the credit card is blank at the beginning of factory shipment. After the user takes the credit card, the user communicates with the card base of the credit card through the mobile phone and sends the portrait information to the card base of the credit card, so that the card surface display information of the credit card is updated to the portrait of the user, and the portrait is continuously displayed before the next card surface display information is updated.
When a user wants to update the card surface display information of the credit card to the business card information, the user can communicate with the card base of the credit card through the mobile phone at any time and send the business card information to the card base of the credit card, so that the credit card which originally displays the portrait displays the business card information and displays the business card information continuously before the next card surface display information is updated. Similarly, the business card information displayed by the credit card can be updated to other self-defined information at any time as long as the user wishes.
It should be noted that the embodiment is only an exemplary illustration, and should not limit the function and the scope of the disclosure.
The following describes an interaction process between the card base and the user side of the physical electronic card in the embodiment of the present disclosure in detail.
Fig. 5 is a flowchart illustrating an updating method of card surface display information of a physical electronic card according to an example embodiment of the present disclosure, wherein the method is executed by a card base of the physical electronic card, and the method includes:
s200, establishing communication with a user side to acquire user-defined information of the user side;
and step S210, updating the card surface display information into the user-defined information.
In the embodiment of the disclosure, when updating the card surface display information of the physical electronic card, the card base establishes communication with the user side to obtain the user-defined information of the user side, and then correspondingly updates the card surface display information.
Specifically, as can be seen from the above description, the card base establishes communication with the user side through the passive communication module, and obtains user-defined information of the user side; and correspondingly updating the card surface display information through the electronic paper display control module.
In an embodiment, before the updating the card surface display information to the user-side customized information, the method includes:
acquiring a user side signature;
and performing signature authentication on the user side signature based on a preset signature authentication algorithm.
In this embodiment, when the physical electronic card leaves the factory and is determined to provide service for a specific user, the card base of the physical electronic card is bound with the user side of the user, so as to ensure that only the user side of the user can update the card surface display information of the physical electronic card, thereby preventing other users from randomly changing the card surface display information of the physical electronic card of the user.
Specifically, after the card base is bound with the user side of the user, the card base acquires a user side signature each time before card side display information is updated to user side custom information, signature authentication is performed on the user side signature based on a predetermined signature authentication algorithm, and the user side is allowed to update the card side information only after the signature authentication passes.
The binding of the card base and the user side of the user refers to a process of establishing mapping between the card base and the user side of the user.
The embodiment has the advantages that only the user side of a specific user can update the card surface display information of the entity electronic card through signature authentication, and the updating safety of the card surface display information is improved.
The binding process between the card base and the user side is described in detail below.
In an embodiment, before the obtaining the user-side signature, the method includes:
and acquiring and storing a user side public key of the user as a service object.
In this embodiment, when the physical electronic card leaves the factory and is determined to provide service for a specific user, the server allocates a pair of public and private keys to the user side of the user, and writes the user side public key of the user into the card base of the physical electronic card, so that the card base stores the user side public key of the user. Namely, the mapping between the card base and the user side of the user is established, and the binding between the card base and the user side of the user is realized. The private key of the user side of the user is only obtained by the server and the user side of the user has the authority to obtain.
In this embodiment, the binding between the card base and the user side is performed based on the distribution of the public and private keys, and it is described that the signature authentication of the card base to the user side is performed based on the asymmetric key system. When signature authentication is carried out, the card base generates information to be signed; after receiving the information to be signed, the user side encrypts the information to be signed by using a private key of the user side based on an asymmetric key algorithm to generate a signature of the user side. Due to the characteristic of the asymmetric key algorithm, the ciphertext obtained by encrypting the plaintext by using the private key can only be decrypted by using the corresponding public key to obtain the original plaintext; similarly, if the original plaintext can be obtained by decrypting the ciphertext by using the public key, it is stated that the ciphertext is necessarily obtained by encrypting the corresponding private key. If the card base can decrypt the user side signature to obtain the original information to be signed based on the corresponding asymmetric key algorithm by using the stored user side public key, the user side which sends the user side signature must hold the user side private key corresponding to the stored user side public key, so that the user side which sends the user side signature is proved to be the binding object of the card base, and the user side signature passes the signature authentication.
In one embodiment, before obtaining the user-side signature, the method includes:
generating information to be signed;
and sending the information to be signed to a user side, so that the user side generates a user side signature for the information to be signed by using a user side private key based on a preset asymmetric key algorithm.
In an embodiment, the information to be signed is: a card-based generated random number.
In this embodiment, the card base generates a random number through a built-in random number generator, and sends the random number to the user side, so as to request the user side to generate a user side signature according to the random number.
This embodiment has the advantage that since the random number is generated on a card basis, it is unpredictable for the user side, thereby improving the security of signature authentication.
In an embodiment, the information to be signed is: product serial number of the card base.
In this embodiment, the card base sends its product serial number to the user side, and requests the user side to generate a user side signature according to its product serial number.
The embodiment has the advantages that the card base can quickly generate the information to be signed, and the efficiency of signature authentication is improved.
It should be noted that the embodiment is only an exemplary illustration, and should not limit the function and the scope of the disclosure.
In one embodiment, asymmetric key algorithms include, but are not limited to: SM2 algorithm, RSA algorithm.
In one embodiment, if the user-side signature passes the signature authentication, it indicates that the user-side is bound to the card base, and the user-side has the right to update the card-side display information. The card base further receives user-defined information sent by the user side, and then updates the card surface display information into the user-defined information.
In an embodiment, if the signature of the user side fails to pass the signature authentication, it indicates that the user side is not bound to the card base, and the card surface display information is not authorized to be updated. The card base refuses to receive the user-defined information sent by the user side and refuses the updating operation of the user side to the card surface information.
According to an embodiment of the present disclosure, as shown in fig. 6, there is also provided a card base of a physical electronic card, the card base including:

In an embodiment, before the obtaining the user-side signature, the method includes:
and acquiring and storing a user side public key of the user as a service object.
In an embodiment, before the obtaining the user-side signature, the method includes:
