Smart card pre-authentication system 【0001】

This creation is about a smart card pre-use authentication system, especially when it is used to protect various smart cards such as ATM cards, financial cards, credit cards, ATM cards, access control cards, and SIM cards (Subscriber Identity Module). An authentication system that avoids being stolen by someone other than the original holder.

【0002】

The smart card, commonly known as a chip card, can store the information of the holder through the memory set in the chip, and thus is widely used in various occasions, such as a cash card, a financial card, a credit card, a cash card, an access control card, and the like. According to the way of reading and writing, the smart card can be divided into a contact smart card, a contactless smart card, and a hybrid smart card with contact and non-contact coexistence. The contact smart card is embedded in a plastic carrier. After the metal electrode is electrically connected to the contact card reading device to obtain power, the chip can be driven by the smart card, and the non-contact smart card is provided with an antenna in the plastic carrier through the wireless proximity to the wireless contactless card reading device. The signal generates energy to drive the wafer inside the smart card to operate.

[0003]

For example, in the case of a financial card having a credit card and a debit card function, the automatic teller machine requires the holder to input a preset password to obtain the right to use the financial card before using the financial card to conduct transactions or services through the automatic teller machine. Therefore, even if the financial card is lost, it is not easy to be stolen by the non-original holder to withdraw cash from the ATM. When using a financial card for consumption, it will only be required to sign the name of the user on the relevant document. Therefore, when the financial card is lost, it is easy to be falsely signed and stolen by the non-original holder to cause property damage.

[0004]

In addition, with the development of wireless transmission technology, some smart cards use wireless transmission technology such as radio frequency (RFID), which is most commonly used in small-volume consumption, such as taking bus, MRT. For public transportation, you can use the leisure card to deduct money through wireless sensing. In order to pursue speed and convenience, this small amount of consumption will not be required to input a password or signature while trading, so as long as such a smart card is lost, pick up The smart card person can directly consume until the smart card is deactivated or the amount stored internally is consumed.

[0005]

Or, the smart card used in the access control system, for speed and convenience, usually has the correct access card to smoothly enter and exit the area with access control, so when the access card is lost, the person picking up the access card can also directly The access control card picked up by the institute enters and exits the access control area.

[0006]

The group unblocking system is to be used to allow any contactless card reading device to perform any one of at least one of reading and writing to the first wafer via the first wireless transmission medium.

[0008]

When the distance between the radio frequency module and the corresponding wireless authenticator is outside the transmission range of the second wireless transmission interface, the radio frequency module is blocked, and the radio frequency module locking system is used to not allow the non-contact card reading. The device performs a reading and writing operation on the first wafer through the first wireless transmission medium.

【0009】

The smart card pre-authentication authentication system of each embodiment of the present invention needs to perform an authentication procedure through a paired wireless authenticator before using the smart card, and the smart card is allowed to be used, so that when the smart card is completely lost, the lost is picked up. The smart card person cannot use the pre-authentication program because there is no paired wireless authenticator, so the lost smart card can still be used, which can improve the security of the smart card.

[0010]

The radio frequency module further includes a second chip electrically connected between the first chip and the first wireless transmission module.

[0011]

The radio frequency module unblocking system is to be used to allow a contactless card reading device to perform any one of at least one of reading and writing to the first wafer via the first wireless transmission medium.

[0012]

When the distance between the wireless RF module and the corresponding wireless authenticator is outside the transmission range of the second wireless transmission interface, the authentication module cannot drive the second chip for authentication through the second wireless transmission interface, and the wireless RF module is blocked. The radio frequency module latching system is to be used to prevent the contactless card reading device from performing read and write operations on the first wafer via the first wireless transmission medium.

[0013]

[0024]

Assuming that the holder loses his smart card 20 but does not lose the wireless authenticator 36, the distance between the smart card 20 and the wireless authenticator 36 will exceed the signal range of the second wireless transmission interface 40, and thus the smart card 20 cannot be paired with The wireless authenticator 36 performs wireless authentication, so that the authentication data stored in the random access memory of the first chip 24 is automatically eliminated, causing the wireless RF module 23 to be blocked, so that the contactless card reading device 42 cannot The first wafer 24 is read and written by the first wireless transmission interface 34, so that the smart card 20 cannot be used.

[0025]

In detail, the authentication module 38 The authentication signal is sent through the second wireless transmission interface 40. The smart card 20 receives the authentication data through the first wireless transmission interface 34 and stores it in the random access memory of the second chip 32. The central processor of the second chip 32 uses the authentication.

So smart card 20 can't be used.

[0033]

In addition, it is assumed that the lost smart card 20 is located in the signal range of the unpaired wireless authenticator 36. Although the lost smart card 20 generates electromagnetic power due to electromagnetic induction of the wireless signal of the unpaired wireless authenticator 36, the non-power is generated. The authentication data in the authentication module 38 of the paired wireless authenticator 36 does not match the authentication data required by the lost smart card 20. Therefore, the central processor of the second chip 32 will find that the authentication data does not match, and thus the switch is not The component 28 outputs a signal, and the switching component 28 remains in a non-conducting state, further not supplying power to the first chip 24, so that the wireless radio frequency module 23 is latched, and thus the contactless card reading device 42 cannot be firstly connected by the first wireless transmission interface 34.

[0037]

In addition, it is assumed that the lost smart card 20 is located in the signal range of the unpaired wireless authenticator 36. Although the lost smart card 20 generates electromagnetic power due to electromagnetic induction of the wireless signal of the unpaired wireless authenticator 36, the non-power is generated. The authentication data in the authentication module 38 of the paired wireless authenticator 36 does not match the authentication data required by the lost smart card 20. Therefore, the central processor of the second chip 32 will find that the authentication data does not match, so the wireless RF Since the module 23 is latched, the non-contact card reading device 42 is still unable to read and write the first wafer 24 by the first wireless transmission interface 34 or the transmission interface 26, so that the smart card 20 cannot be used.
