Example 1
Fig. 1 is a schematic flow chart of an identification method of a smart card according to an embodiment of the present invention, where the method is described as follows.
Step 101: and receiving the information of the intelligent card sent by the terminal equipment.
The intelligent card information comprises identification information of the intelligent card and encrypted account information in the intelligent card.
In step 101, before performing a write operation on a smart card, a terminal device may read smart card information of the smart card, where the smart card information may include identification information of the smart card or encrypted account information of the smart card.
In the embodiment of the present invention, the smart card information may be obtained by reading the smart card information by the terminal device in a near field communication manner.
Specifically, the terminal device may be configured to install an application program for reading the information of the smart card, the terminal device may open the application program installed in the terminal device before reading the information of the smart card, and after opening the application program, the smart card may be attached to the terminal device, so that the terminal device may read the information of the smart card through near field communication.

It should be noted that, in the embodiment of the present invention, the security level requirement on the account information in the smart card is higher than the security level requirement on the identification information of the smart card, so to ensure the security of the account information in the smart card, when the terminal device reads the smart card information, the terminal device may read the identification information of the smart card and the encrypted account information in the smart card.
In order to identify the account information in the smart card, the terminal device may send the smart card information to the server after reading the smart card information, and at this time, the server may receive the smart card information sent by the terminal device.
Step 102: and searching a decryption password corresponding to the identification information from a password database according to the identification information of the intelligent card.
The database comprises identification information of different intelligent cards and decryption passwords corresponding to the identification information of the intelligent cards.
In step 102, after receiving the smart card information sent by the terminal device, the server may search, according to the identification information of the smart card included in the smart card information, a decryption password corresponding to the identification information of the smart card from a database, so as to decrypt the encrypted account information using the searched decryption password.
It should be noted that, in the embodiment of the present invention, the database stores the identification information of different smart cards and the decryption passwords corresponding to the identification information of the smart cards in advance, so that after receiving the information of the smart cards, the server may search the database for the decryption passwords corresponding to the identification information according to the identification information of the smart cards included in the information of the smart cards.
Specifically, in practical applications, when a user registers to obtain a smart card, the server may provide, to the user, an encryption password for encrypting account information in the smart card, so that the user may encrypt the account information in the smart card using the encryption password provided by the server, and after encrypting the account information in the smart card, when the user reads the account information in the smart card using the terminal device, the user reads the encrypted account information using the encryption password, so that other users cannot directly obtain the account information in the smart card, thereby improving the security of the account information in the smart card.
After the server provides the encrypted password to the user, the server may determine a decryption password corresponding to the encrypted password, so that the server may decrypt the account information encrypted using the encrypted password using the decryption password.
After determining the decryption password, the server may establish a correspondence between the decryption password and the identification information of the smart card, and store the correspondence in a database.
In this way, after receiving the identification information of the smart card, the server may search for the decryption password corresponding to the identification information from the database according to the identification information of the smart card, so as to decrypt the encrypted account information using the searched decryption password.
Step 103: and decrypting the encrypted account information in the smart card by using the decryption password, and identifying the smart card according to a decryption result.
In step 103, after finding the decryption password corresponding to the identification information of the smart card, the server may decrypt the encrypted account information in the smart card, so as to identify the smart card according to the decryption result.
It should be noted that, in the embodiment of the present invention, identifying the smart card may be determining whether the account information in the smart card is legal, or further determining to obtain the account information in the smart card when determining that the account information of the smart card is legal.
Specifically, in the embodiment of the present invention, when the smart card is identified according to the decryption result, at least the following two results exist:
the first result is: when the decryption result of decrypting the encrypted account information in the smart card by using the decryption password is the account information in the smart card, determining that the account information of the smart card is legal;
the second result is: when the encrypted account information in the smart card is not obtained as a decryption result of decrypting the encrypted account information by using the decryption password, whether the account information of the smart card is legal or not cannot be determined.
For the first result:
in practical application, the encryption password provided by the server for encrypting the account information of the smart card is matched with the encryption password stored in the database and corresponding to the identification information of the smart card, that is, only the decryption password matched with the used encryption password can be successfully decrypted for the account information encrypted by using the encryption password.
In this way, if the server decrypts the encrypted account information in the smart card by using the searched decryption password, so as to obtain the account information in the smart card, that is, the decryption is successful, it can be shown that the searched decryption password is matched with the encrypted password for encrypting the account information, that is, the encryption password used by the terminal device is not wrong, the terminal device sends the smart card information to the server, the smart card information is not tampered, and at this time, the server can determine that the account information of the smart card is legal.
When determining that the account information of the smart card is legal, the server may determine to obtain the decrypted account information of the smart card.
For the second result:
if the server decrypts the encrypted account information in the smart card by using the searched decryption password, the account information in the smart card is not obtained, that is, the decryption fails, it can be shown that the searched decryption password is not matched with the encrypted password for encrypting the account information, that is, the encryption password used by the terminal device is wrong, or the terminal device sends the smart card information to the server, the smart card information is tampered, and at this time, the server cannot determine whether the account information of the smart card is legal or not.
In practical application, the reason for causing the decryption failure of the server may be that information in the smart card is tampered, an encryption password for encrypting account information in the smart card is modified, the smart card information is illegally tampered in the process of being transmitted to the server, or the type of the smart card does not meet the requirement of the server (for example, the server needs to identify an ETC card, and the terminal device reads bus card information), which is not specifically limited in the embodiment of the present invention.
