Abstract

In a method for generating program code in a load format for a portable data carrier, a pseudo library is used, which differs from the library located on the data carrier in such a way that at least some of the internal workings of the library located on the data carrier are absent or hidden or masked in the pseudo library. In a method for providing executable program code in the portable data carrier, the program code in load format is linked relative to the library located on the data carrier. A device and a computer program product have corresponding features. The invention provides secure, privacy-safeguarding technology, which allows the generation of program code in a load format for a portable data carrier and the provision of executable program code in the portable data carrier.
