The invention provides a magnetic card magnetic medium information safety writing method and a system, and the method comprises the following steps: receiving a magnetic card magnetic medium information modification request inputted by a user; reading original magnetic card magnetic medium information containing additional data from a magnetic card according to the magnetic card magnetic medium information modification request; comparing the read original magnetic card magnetic medium information with the stored magnetic card magnetic medium information containing the additional data; calculating the read original magnetic card magnetic medium information if the read original magnetic card magnetic medium information is the same with the stored magnetic card magnetic medium information, and generating the new magnetic card magnetic medium information; and writing the new magnetic card magnetic medium information into the magnetic card. The method and the system can lead the magnetic card magnetic medium information stolen by a criminal to become invalid by changing the magnetic card magnetic medium information of the magnetic card, thereby protecting interests of the magnetic carduser.
Description
technical field [0001] The invention relates to financial systems and electronic industry information security technologies, in particular to a method and system for securely writing magnetic card and magnetic medium information in the financial system. Background technique [0002] With the continuous improvement of the card-using environment in our country, more and more people use magnetic cards. With the popularity of magnetic cards, the methods of magnetic card crimes have also increased. In addition, the information security awareness of personnel in some domestic card-related units is not strong, and the lack of security methods has led to the leakage of many magnetic card magnetic media information. There are various means of crime, for example: installing devices for stealing magnetic media information and devices for stealing passwords on the access control of self-service banking areas, installing devices for stealing magnetic media information and cameras for ste...
