Abstract

A method of writing data into identification media of various types (IM-X, IM-Y) via assigned write/read stations WR in accordance with an embodiment of the present application includes a step wherein, a virtual, identification media-independent reference file system RFS is defined. All access keys RKi are replaced by a file system key FSK and all access rights ACi of subsections Bi are suspended and a file system FS, corresponding to the reference file system RFS, is initialized or written into the identification media: (FS(IM-X), FS(IM-Y)). In doing so, a file system starting point (FS-S(IM-X), FS-S(IM-Y)) is defined in the identification media (IM(FS) and in the assigned read/write stations WR(RFS) so that applications (App(RFS) corresponding to the virtual reference file system RFS can be written into the identification media and executed. The method allows for the writing into or execution of generally defined applications (App(RFS) into initialized identification media of various types (IM-X(FS), IM-Y(FS)) without adapting them.

Claims21

Dependent claims

A method utilizing at least one computer processor for writing data, via a write/read station, into identification media, the method comprising:

assigning the write/read station to the identification media, wherein a first identification medium IM-X being of a different medium type from a second identification medium IM-Y, and each identification medium comprises an application area App-Ar freely accessible to applications App, with a plurality of application access keys RKi, RKj, and a plurality of access rights ACi ACj for part areas Bi, Bj of the application area App-Ar,
initializing a file system FS for each identification medium, which corresponds to a defined, virtual reference file system RFS which is independent of the identification medium, the initializing performed such that all of the plurality of access keys RKi, RKj are replaced by a file system key FSK of the assigned write/read station, and all of the plurality of access rights ACi, ACj of the part areas Bi, Bj are disabled, and
subsequently, writing the file system FS, in accordance with a identification medium being initialized, into the part areas Bi of the first identification medium and into the part areas Bj of the second identification medium, and thereby defining a file system starting point in each of the first identification medium and the second identification medium, wherein
the file system starting point being defined in the assigned write/read station corresponding to the virtual reference file system RFS, so that any applications App(RFS) defined according to the virtual reference file system RFS are written into each identification medium via the assigned write/read station, and executed subsequently to the writing being successful,
the file system FS is divided into a file system header FS-H and into a file system application area FS-App-Ar, or that the file system starting point FS-S lies in the file system header FS-H, and
with the file system key FSK, access is allowed only for the file system starting point FS-S or the file system header FS-H.

A non-transitory identification medium configured to be written into and read from by an assigned write/read WR station, the identification medium incorporating an application area App-Ar freely accessible to applications App, with a plurality of access keys RKi and a plurality of access rights ACi for part areas Bi of the application area App-Ar, the identification medium comprising:

a file system FS which corresponds to a defined, virtual reference file system RFS independent of the identification medium, wherein
all of the plurality of access keys RKi are replaced by a file system key FSK of the assigned write/read WR station, and
all of the plurality of access rights ACi of the part areas Bi are disabled, and the file system FS, in accordance with the identification medium, is written into the identification medium, and thereby a file system starting point is defined in the identification medium, wherein
the file system starting point being defined in the assigned write/read station corresponding to the virtual reference file system RFS, so that applications App(RFS) defined according to the virtual reference file system RFS are written into the identification medium via the assigned write/read station and executed subsequently to the writing being successful,
the file system FS is divided into a file system header FS-H and into a file system application area FS-App-Ar, or that the file system starting point FS-S lies in the file system header FS-H, and
with the file system key FSK, access is allowed only for the file system starting point FS-S or the file system header FS-H.
