Description
Technical Field
The invention relates to the technical field of communication safety, in particular to a terminal password keyboard system based on film card hardware and a PIN code (or signature password or password and the like, hereinafter collectively referred to as PIN code) protection method.
Background
The film sticking card is used as a hardware carrier and matched with a terminal application program to provide a shield-like function for the application program, and the function is widely used in application systems such as mobile banking, eID (electronic identity) of citizen networks and the like. In the process of using the film-sticking card, a user needs to input a personal PIN code (or a signature password or a password, and the like, hereinafter collectively referred to as a PIN code) through a terminal application program popup box so as to perform identity authentication, the PIN code is stored in a film-sticking card carrier, after the PIN code input by the user is transmitted into the carrier, a program on the film-sticking card can judge whether the input PIN code is consistent with the PIN code stored in the carrier, if so, the next operation (such as signature) is performed, and otherwise, the next operation is refused. Therefore, the purpose of verifying the identity legitimacy of the user is achieved, and the method of using a hardware carrier as a substitute shield greatly improves the safety compared with the method of using no carrier.
At present, PIN codes are input on terminal application programs, and a native keyboard module provided by a terminal operating system (such as a mobile phone OS) is generally adopted, and two possible risks are generated in the use of such a keyboard: the number or character position on the interface of the user for inputting the PIN code is relatively fixed, so that a third party program such as a Trojan horse program can be used for conjecture by monitoring the coordinate position of the interface when the user clicks, and the true PIN code of the user can be conjectured; and two are that when the PIN code data is transmitted from the terminal application program to the inside of the film-sticking card carrier, the data transmission between the two devices needs to be transmitted through the connection line of the metal contact, which can be used by a third party for capturing the message by monitoring the electrical characteristics on the connection line of the contact, and if the PIN code is transmitted in a plaintext mode, the plaintext data can be estimated by the monitoring program through the monitoring of the electrical characteristics.
