Abstract:
1. A method of determining the compatibility, for application to a smartcard, of first and second personalization profiles for respective first and second applications, the first and second applications requiring respective first and second file trees on the smartcard for execution of the first and second applications by a computer that is coupled to the smartcard, the first and second file trees having respective first and second sets of paths, the method comprising: determining if the first and second sets are disjoint; if the first and second sets are disjoint, returning a signal indicative of the compatibility; if the first and second sets are not disjoint and if each path of the first and second sets of paths comprises file attributes, and one path of the first set of paths is also a path of the second set of paths, determining if file attributes of said one path are identical in the first file tree and the second file trees or less restrictive in the first file tree than in the second file tree; and returning a signal indicative of the compatibility if the file attributes of said one path are identical in the first file tree and the second file tree or less restrictive in the first file tree than in the second file tree.
