Password system with anti-skimming function

Abstract

The invention provides a cryptosystem with an anti-recording function, and the cryptosystem is suitable for locking and unlocking one object or condition, wherein the cryptosystem comprises a transmitting module and a receiving control module; the transmitting module comprises a microcontroller, a first signal receiver and a first power supply; the first signal receiver is driven by the microcontroller to transmit at least one code signal and the code signal is provided with a plurality of identification codes; a pre-set time interval exists between the adjacent identification codes and the receiving control module comprises a microcontroller, a second signal receiver and a second power supply; the second signal receiver can receive the code signal which is sent by the first signal receiver; and the microcontroller sends out a control signal to selectively lock and unlock the object or condition after the identification codes and the time interval between the adjacent identification codes are confirmed by the microcontroller.

Description

Technical field [0001] The invention relates to a cryptographic system, in particular to a cryptographic system with anti-skimming function. Background technique [0002] At present, the convenience of credit card can be known according to its popularity. However, it is because the convenience of the credit card in the consumption process even reaches the situation where the card can almost be recognized and not recognized, leading to the popularity of counterfeiters, resulting in card holders People and card-issuing banks suffered huge losses, which disrupted financial order. [0003] Credit card counterfeiters usually swipe the credit card through a recorder or use magnetic induction to steal the cardholder’s personal data (DATA), and then create a counterfeit card. The customer secretly records the data during the checkout period at the checkout counter, and the time is only one to two seconds, which is not easy to be detected. Therefore, most people do not know whether the cre...

Problems solved by technology

[0005] However, no matter how fast and sharp the warning is in the above-mentioned method, if the data is intercepted or skimmed by hackers during the data transmission process, it is still unavoidable that the credit card 2 will be made into a counterfeit card due to data leakage and lose the warning function

[0006] The above examples are just one of the ones we often encounter in our daily life. Any remote control car lock, home door protection, or various authentication behaviors on the Internet are all related to the importance of data protection. Therefore, if it is only negative and Blindly adding various warning functions will not only cause inconvenience in life, but also cannot truly prevent illegal activities such as skimming personal data, which will only increase property losses
