Authentication method, authentication apparatus and authentication device

A terminal, comprising a hardware processor, wherein

• when the terminal is inserted with a storage card storing a fixed program, the program is automatically run after the terminal starts up to cause the hardware processor of the terminal to execute the following steps:
• comparing a first terminal identification code stored in the storage card with a second terminal identification code of the terminal to judge whether the first terminal identification code matches the second terminal identification code and obtaining a first judgment result;
• when the first judgment result is NO,
• popping up a dialog box to remind a user of inputting another terminal identification code, and when receiving a terminal identification code input by a user, judging whether the terminal identification code input by the user matches the first terminal identification code stored in the storage card;
• when the terminal identification code input by the user matches the first terminal identification code stored in the storage card, popping up another dialog box to remind the user of whether to replace the first terminal identification code stored in the storage card;
• and when a replacement instruction of the user is received, writing the second terminal identification code of the terminal into the storage card according to the replacement instruction of the user, and deleting the first terminal identification code stored in the storage card after the second terminal identification code is stored by the storage card;
• when the terminal identification code input by the user does not match the first terminal identification code stored in the storage card, deleting user data stored in the storage card.

An authentication method, comprising:

• after a terminal with a second terminal identification code and where a storage card is inserted starts up, a fixed program preset in the storage card is automatically run to make the terminal perform the following steps:
• comparing a first terminal identification code stored in the storage card with the second terminal identification code of the terminal and to judge whether the first terminal identification code matches the second terminal identification code and obtaining a first judgment result;
• when the first judgment result is NO,
• popping up a dialog box to remind a user of inputting another terminal identification code, and when receiving a terminal identification code input by a user, judging whether the terminal identification code input by the user matches the first terminal identification code stored in the storage card;
• when the terminal identification code input by the user matches the first terminal identification code stored in the storage card, popping up another dialog box to remind the user of whether to replace the first terminal identification code stored in the storage card;
• and when a replacement instruction of the user is received, writing the second terminal identification code of the terminal into the storage card according to the replacement instruction of the user, and deleting the first terminal identification code stored in the storage card after the second terminal identification code is stored by the storage card;
• when the terminal identification code input by the user does not match the first terminal identification code stored in the storage card, deleting user data stored in the storage card.
