Problems solved by technology

[0003] However, with the continuous enrichment of applications, the demand for services continues to increase, and the storage space of the user's smart card (or the embedded security element eSE in the mobile terminal) is limited, and the component information and personal data of the application occupy a large amount of storage space. There are fewer applications to download; at the same time, when the space of the user's smart card is insufficient, the user needs to choose to delete the existing smart card application to free up space, and deleting the smart card application will easily cause the loss of application personal data; and when the user needs to install multiple applications and When the space is insufficient, the smart card or eSE needs to be replaced, and the eSE is embedded in the mobile terminal, resulting in high replacement costs
[0004] For the above-mentioned low utilization rate of smart card storage space, no effective solution has been proposed yet

Abstract

The invention provides an intelligent-card data storing method and device and an intelligent card. The method includes the steps that the intelligent card receives an application data package sent by a reliable service platform, wherein the application data package comprises method assembly data; the intelligent card obtains assembly identification information corresponding to the method assembly data, wherein the assembly identification information comprises application identifiers of the application data package and checking values of the method assembly data; the intelligent card compresses the method assembly data with the data compression algorithm; the intelligent card stores compressed recorded information and the compressed method assembly data, wherein the compressed recorded information comprises the assembly identification information, the storage addresses of the compressed method assembly data and the length of the compressed method assembly data. By means of the intelligent-card data storing method and device and the intelligent card, the storage space occupied by application data can be reduced, and the utilization ratio of the storage space of the intelligent card is increased.

Description

technical field [0001] The invention relates to the technical field of smart cards, in particular to a method and device for storing data in a smart card and a smart card. Background technique [0002] With the popularization of smart cards and the continuous enrichment of daily consumption and mobile payment scenarios, various applications based on smart cards provide users with more convenient and safer services. The smart card in the hands of the user can not only complete the daily cash business, but also participate in other online and offline preferential activities, points, life payment, transportation and other multi-channel and multi-category consumption activities. Users can also independently download smart card applications of merchants, banks and other operating institutions through mobile terminals to complete payment, points and other services. [0003] However, with the continuous enrichment of applications, the demand for services continues to increase, and...
