Example Embodiment

[0060] Embodiment 1. A method for detecting personalization data of a financial IC card, such as figure 1 Shown, including:

[0061] S101. Analyze the original personalized data file of the first card issuer according to the personalized data template and protection method of the first card issuer to obtain the plaintext of personalized data;

[0062] S102: Convert the plaintext of the personalized data into personalized data in a predetermined format, and use the key data uniquely corresponding to the financial IC card to be detected to encrypt and convert it into personalized data in the predetermined format;

[0063] S103: Parse the encrypted personalization data in a predetermined format, and verify the correctness of the internal data of the financial IC card to be detected after personalization according to the parsed template data.

[0064] As the current card issuers do not have a unified data template and file protection method, so the card issuers are different, the original ...

Example Embodiment

[0094] Embodiment 2. A detection system for personalization data of a financial integrated circuit card, such as figure 2 Shown, including:

[0095] The data analysis module is used to analyze the original personalization data file of the first card issuer according to the personalization data template and protection method of the first card issuer to obtain the plaintext of the personalized data (not saved);

[0096] The data conversion module is used to convert the plaintext of the personalized data received from the data analysis module into personalized data in a predetermined format, and encrypt and convert it into personalized data in a predetermined format using the key data unique to the financial IC card to be detected ;

[0097] The data detection module is used to parse the encrypted personalization data in a predetermined format, and verify the correctness of the internal data of the financial IC card to be detected after the personalization according to the parsed temp...

Abstract

The invention provides a financial integrated circuit card personalized data detecting method and system. The method includes the following steps that according to a personalized data template and a protection manner of a first card issuing mechanism, primitive personal data files of the first card issuing mechanism are analyzed to obtain a personalized data cleartext; the personalized data cleartext is converted to personalized data of a preset format and the unique secret key data corresponding to a financial IC card to be detected is encrypted and converted into the personalized data of the preset format; the encrypted personalized data of the preset format are analyzed and according to analyzed template data, correctness of the data in the financial IC card to be detected after the IC card is personalized is verified. According to personalized data of different card issuing mechanisms, uniform personalized data detection can be carried out and managing cost of personalized detection is reduced.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and system for detecting personalization data of a financial integrated circuit card. Background technique [0002] Due to the poor confidentiality and security of the magnetic stripe card, the information on the magnetic stripe is easy to be read out, and it is also easy to be copied illegally. At present, there have been many incidents of the magnetic stripe card being copied and stolen at home and abroad. The financial IC (integrated circuit) card uses a CPU (central processing unit) chip with independent computing functions, and has a strong security authentication mechanism, which greatly improves the security level. Therefore, in order to prevent the occurrence of magnetic stripe card crimes, the world has accelerated the pace of migration from magnetic stripe cards to financial IC cards. [0003] With the further deepening of the migration of the global EMV (t...
