....is introduced to analyze the user s write capability, is also used to examine more elaborately how the user can update the data, and to investigate how it interacts with inferability. There are many researches on access control using views in object oriented databases [TYI88, HZ90, AB91, Run92, OT94] Although the idea of access control using views defined by functions is essentially the same concept with access control using functions, those researches do not discuss security issues. Our technique can be applied to the verification of view definitions in those systems as well. In [DAH ....
.... name dependent access control, and a kind of context dependent control [FSW81] Contentdependent control, which is control depending on the contents of the actual data, could be also integrated by introducing some existing techniques, such as classes with predicates [TYI88, AB91, SLT91, Run92, OT94] The function definition language we defined in this research is quite simple language. Including more language features into it, such as conditional branch, recursion, and polymorphism, is also an important issue for future researches. We also assume a rather simple data model in this ....
