Embodiment Construction

[0023] figure 1 It is a flow chart of the application data sharing method on the smart card provided by the present invention.

[0024] Such as figure 1 As shown, the method includes:

[0025] Step 101, creating sub-application data block information of a parent application on a smart card, where the sub-application data block information includes an access control list (ACL).

[0026] Wherein, the ACL of the sub-application data block stores identification (ID) information of other sub-application data blocks that are allowed to access the sub-application data block.

[0027] Wherein, the ID information of the other sub-application data blocks may be stored in the ACL in the form of the full text of the ID, or in the form of the ID range, or in the form of ID flag bits. In short, as long as the ACL of the sub-application data block can determine Whether other sub-application blocks are allowed to access the sub-application data block is sufficient, and the present inventio...

Abstract

The invention provides an application data sharing method of a smart card and the smart card. The method comprises the following steps that: the sub-application data block information of a parent application is built on the smart card, wherein the sub-application data block information comprises an access control list (ACL); identification (ID) information of the other sub-application data blocks allowed to access the sub-application data block is stored in the ACL; a sharing request of a second sub-application data accessed by a first sub-application is received, the sharing request is authenticated according to the authentication information of the first sub-application; after passing through the authentication, the ACL of the second sub-application data block is searched to judge whether the ID information of the first sub-application data block is stored; if so, the sharing data of the second sub-application is returned; and if not, the application data sharing is failed. By adopting the method provided by the invention, the safety of the application data sharing can be improved.

Description

technical field [0001] The invention relates to the technical field of smart cards and databases, in particular to a smart card application data sharing method and the smart card. Background technique [0002] With the maturity of smart card technology, various applications can be carried on smart cards, such as public transportation applications, financial applications, social security applications, medical applications, etc. By popularizing smart cards carrying various applications, the lives of users can be greatly facilitated. [0003] For example, in an enterprise, the enterprise one-card system is helpful for information exchange, sharing and unified management within the enterprise. The one-card system used in the field of enterprise management has now covered personnel identification, employee attendance, salary management, personnel management, electronic Access control, entrance and exit control, vehicle entry and exit management, employee internal consumption man...
