发明名称 Verfahren zum Verändern von Programmcode eines tragbaren Datenträgers mittels Patchdaten
摘要 The method involves comparing original and new memory images (40, 42) of a non-volatile rewritable memory to identify sub ranges of the images, where the sub ranges differ from one another. Data are recorded for identified sub ranges of the images to generate patch data, where the recorded data define the sub ranges and new program codes for the sub ranges. An executable program code is modified as indicated in the patch data. - Independent claims are also included for the following: - (A) a computer program product containing patch data - (B) a program control device for executing a method of generating patch data.
