摘要： A portable data carrier (10) typically the size of a standard plastic credit card is usable in a variety of applications, from custom repertory dialing to storage of individual medical and/or banking records. The portable data carrier provides a high security file system capable of supporting multiple applications, all independent of the details of the data carrier's generic internal structure. Although the data carrier looks and feels much like an ordinary credit card, it includes a computer (110) and an electrically erasable programmable read-only memory (115). Power for operation of the portable data carrier is provided from an associated station (118) via a reader/writer (15). The reader/writer also couples data between the data carrier and the associated station. Security is enhanced since application software in the station receiving and interpreting the data from a file sees a contiguous stream of bytes relating only to the file of the application being accessed. No information is provided to a user of a particular application about other applications in the data carrier or about the data carrier's internal file structure.

摘要： A file system for a portable data carrier (10) provides improved security for files which support multiple applications, from custom repertory dialing to storage of individual medical and/or banking records. Although the portable data carrier looks and feels much like an ordinary credit card, it includes a computer (110) and an electrically erasable programmable read-only memory (115). Power for operation of the portable data carrier is provided from an associated station (18) via a reader/writer (15). The reader/writer also couples data between the data carrier and the associated station. The applications reside in multiple files (42-48) in memory on the portable data carrier. Appropriate application software residing in the station, when accompanied by an appropriate password, enables the retrieval and modification of these files. A separate password is required for gaining access to each of designated levels of interaction between the portable data carrier and the associated station. Additional restrictions such as requiring an additional password for writting to a file and also allowing a user logged in at a particular security level to only append information to a file may be imposed in accordance with file security on the portable data carrier. And since each of the files may have its own security requirements, multiple applications may exist on the portable data carrier without conflict or confusion.

摘要： A portable data carrier system (10, 15, 18) provides improved security for files (31-33) which support multiple applications, from custom repertory dialing to storage of individual medical and/or banking records. Included in the system is a portable data carrier (10) which looks and feels much like an ordinary credit card. The portable data carrier, however, includes a computer (110) and an electrically erasable field programmable read-only memory (115). Power for operation of the portable data carrier is provided from an associated station (18) via a reader/writer (15). The reader/writer also couples data between the data carrier and the associated station. Operation of the data carrier is through an executive operating system that is accessed from the station via a set of commonly understood command primitives. These command primitives manipulate the files in the data carrier in accordance with security requirements. Security is enhanced since the station application software receiving and interpreting the data from a file sees a contiguous stream of bytes relating only to the file of the application being accessed. No information is provided to a user of a particular application about other applications in the data carrier or about the data carrier internal file structure.
