  2. The Milano Model • The Milano Model is a flexible access control mechanism for Web documents • It extends the traditional approaches developed for both DBMS and Web environments • Two main extensions: • More expressive filtering policies • More refined user management

  3. User Management Main features: • Flexible specification of filtering policies based not only on user identities but also on their profile • Users are assigned a set of credentials based on their characteristics • This approach simplifies the work of institutional users (e.g. schools and firms), who have to specify and manage filtering policies for a great number of users according to their profile

  4. Filtering Policies Main features: • Multistrategy (content-independent/content-dependent) filtering of Web documents • Content-based filtering almost independent from the annotation approach • Support for both: • NKRL EUFORBIA labels • PICS content labels (in particular, ICRA/RSACi content labels) • Positive and negative policies at different granularity levels • Exception management and policy propagation
