The key of security on commercial information systems is to preserve the data integrity within them.Although many integrity principles have been discussed
there is still lack of a systematic commercial secure policy model.A Formal Commercial Secure Policy Model Based on Framework(FB-FCSM) is proposed
which integrates multi-integrity-principle into one systematic commercial secure model.The model has not only good compatibility but also sound scalability
and is a refinement of Clark-Wilson Integrity Secure Policy.
