The technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The data storage location of the IC card is composed of a plurality of sectors, each sector is independently controlled for access, each sector is composed of a plurality of data blocks, and data is usually stored in a binary manner in each data block of each sector.
Referring to fig. 1, the application discloses a data storage method, which comprises the following steps:
s1, setting one sector in an IC card as a main sector and the other sectors as authority sectors;
the main sector reserves storage spaces for storing card numbers, setting information, passwords of all authority sectors and verification data of the main sector respectively; the authority sector is used for storing authority information and authority sector check data, and each authority information has an independent authority number. Wherein the authority information is a binary number, the authority information is 1, which indicates that the authority exists, and 0 indicates that the authority exists. In one embodiment, each authority sector stores 256 authority information, which is 0 in an initial state.

Specifically, the application environment of the IC card includes enterprise access control, hospital access control, school access control, etc., and the data set includes a user information data set and an IC card information data set. Wherein the fields stored in the user information dataset include unit number, gender, job number, user ID, department and/or job position; the field in which the IC card information data set is stored includes an item number and/or a card manufacturing time. The data can be used for controlling the schemes such as safety access, inquiring the access control use condition, optimizing the system and the like.
As a preferred embodiment, the step S2 further includes:
setting a storage rule of each data set; specifically, the storage rules are uniformly managed in the access control system, including a storage user information data set rule and a storage IC card information data set rule. Wherein, the rule of storing the user information data set is that when new user information exists, the system automatically updates the user information data set; the rule of the information data set of the stored IC card is that when the IC card is manufactured, the system automatically updates the rule of the information data set of the IC card.

P E =P I1 ×P I2 ×...×P In
wherein P is I1 、P I2 And P In Respectively represent authority numbers I 1 、I 2 And I n Is provided with authority information of (a). The rights information is 0 or 1, i.e. the rights information P corresponding to the device with the device number E only I1 -P In When all are 1, P E Device authentication pass =1; p (P) E When=0, the device authentication fails.

In a preferred embodiment, after each device number is set to be associated with a corresponding authority number, the method further includes the steps of:
and setting authority sectors corresponding to each field in the data set. For example, setting the unit number field in the user information data set to correspond to the jth authority sector, and indicating that authority numbers corresponding to the data in all the unit number fields are in the jth authority sector; for another example, if the unit numbers and job fields in the user information data set are set to correspond to the kth authority sector, the authority numbers corresponding to the data representing all the unit numbers and job fields are all in the kth authority sector. In this embodiment, by setting the authority sector corresponding to each field in the dataset, authority data can be managed and protected more finely and finely, so as to realize independent management of each field.
