METHOD AND SYSTEM FOR DISCRIMINATING CALL AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To discriminate a guaranteed call by deciding whether or not it is guaranteed that all targets of a call belong to a package in which a class layer graph and access permission are incorporated. SOLUTION: Each package to be analyzed is examined to determine whether or not it is sealed and signed; if so, the class layer graph of the package is structured and access permission is determined for its respective package components. Then they are used together with the fact that it is recognized that the package is sealed and signed, and it is decided whether or not it is guaranteed that all targets of a call in the package belong to the package. Consequently, a guaranteed call can be discriminated.
