Embodiment 1

[0060] Embodiment one, a kind of detection method of personalization data of financial IC card, such as figure 1 shown, including:

[0061] S101. 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 plain text of the personalization data;

[0062] S102. Convert the personalization data in plain text into personalization data in a predetermined format, and convert it into personalization data in a predetermined format by encrypting the key data uniquely corresponding to the financial IC card to be detected;

[0063] S103. Analyzing the encrypted personalized data in a predetermined format, and verifying the correctness of the personalized internal data of the financial IC card to be detected according to the parsed template data.

[0064] Since each card issuer does not have a unified data template and file protection method at present, the original pe...

Embodiment 2

[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, and obtain the plain text of the personalization data (not saved);

[0096] The data conversion module is used to convert the personalization data received from the data parsing module into personalization data in a predetermined format in plain text, and encrypt and convert the personalization data into predetermined format using the unique key data corresponding to the financial IC card to be detected ;

[0097] The data detection module is used to analyze the encrypted personalized data in a predetermined format, and verify the correctness of the personalized internal data of the financial IC card to be tested according to the...

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...
