Embodiment 1

[0061] figure 1 It is a flow chart of a method for generating smart card data disclosed in this embodiment, including the following steps:

[0062] Step S101, loading system files, so that the subsequent steps can process the system files;

[0063] Step S102, read the attributes of the system file, the attributes of the system file include information such as file path, file length, initial value, file structure, record number, record length, read and write permissions, and links.

[0064] Step S103, converting the information including the attributes of the system file in the system file into coded information conforming to the data specification of the operating system COS file in the smart card;

[0065] In this embodiment, the specific method of the information conversion process is to fill the file content according to the file length and initial value, and convert the file structure and read and write permissions and other information containing the attributes of the sy...

Embodiment 2

[0074] The difference between the method for generating smart card data disclosed in this embodiment and the first embodiment is that step S104 in the first embodiment is embodied, and the process of generating file system data by using the encoded information is described in detail. This embodiment is only As a preferred solution for realizing this process, the specific realization of this process is not limited to the scope disclosed in this embodiment.

[0075] figure 2 It is a flow chart of the method for generating smart card data further disclosed in this embodiment on the basis of Embodiment 1, wherein, steps S201, S202 and Step S204 are the same as those described in Embodiment 1. An example of a different process to describe in detail:

[0076] Step S203, put the information including the attribute of the system file read in step S202 into a preset container, so that the attribute of the system file only needs to be read once, thereby avoiding the need to repeatedly...

Embodiment 3

[0091] The difference between this embodiment and the second embodiment is that the process of storing the system file after setting the link identifier in step S206 of the second embodiment is embodied. In this embodiment, the background preset container is specifically a tree structure . Those skilled in the art can understand that the purpose of adopting the tree structure in this process is to enable the technicians to intuitively see the position and depth of each file in the processing process when processing the system files, so as to facilitate the control of the processing process , however, the method that can realize this function is not limited to the tree structure, which structure to choose depends on the specific environment of the design.

[0092] image 3 It is a detailed flow chart of the method for generating smart card data further disclosed in this embodiment on the basis of Embodiment 2. After step S205 of Embodiment 2, the following steps are included: ...

Abstract

The invention discloses a method for generating intelligent card data, which comprises the steps of: loading system files, reading attributes of the system files, and putting information containing the attributes into a preset container; converting the information containing the attributes of the system files in the system files into encoding information according with the specification of COS file data of an operating system in an intelligent card; generating file system data by utilizing the encoding information; and merging the file system data with the COS file data to generate intelligent card data. In the method, the information of the system files is converted into the encoding information according with the specification of the COS file data, so that the converted file system datacan be merged with the COS file data; and the COS file data is downloaded to create the system files in the intelligent card, so that the production and development processes of the intelligent card are simplified, and the large-scale production time of the intelligent card is saved. Corresponding to the method, the invention also discloses a device for generating the intelligent card data.

Description

technical field [0001] The present invention relates to the field of smart cards, more specifically, to a method and device for generating smart card data. Background technique [0002] In recent years, with the development of smart card technology, smart cards have been widely used in telecommunications, finance, transportation, medical and other fields due to their high memory capacity and logic computing capabilities. [0003] In the field of telecommunications, SIM cards are used to store information and uniquely identify user identities. Due to the large-capacity storage capacity of smart cards, the telephone directory can be stored on the card. The microprocessor in the card greatly improves the security of user accounts; in finance In the field of smart card technology, in addition to retaining the financial functions of traditional bank cards, the bank card developed by smart card technology can also use the memory and microprocessor on the card to provide more value...
