1. 1 WRAP UP Joan Feigenbaum http://www.cs.yale.edu/homes/jf PORTIA Project Site Visit Stanford CA, May 12-13, 2005

2. 2 Benefits of a Large-ITR Grant Very high levels of Inter-institutional collaboration Inter-disciplinarity Visibility and outreach Integration of research and education Public service by PIs

3. 3 Accomplishments Reported Today RW: PPDM and MDS algorithmics AB: Policy specification and enforcement DB: Browser-based ID protection HG: Retaining control of outsourced data JF: Highly collaborative education and outreach SF: Novel data representations AS: Domain-specific DB challenges HN: Novel conceptual framework

4. 4 Other Highlights of the First 1.5 Years Search of access-controlled content Economic analysis of “trusted platforms” Provably secure query auditing Privacy in public databases BCC privacy violations in encrypted email Cybercrime and cyberpolicing The world changed (e.g., wrt spam, NGSCB). 

5. 5 The Powerful are Pessimistic “You already have zero privacy. Get over it!” – Scott McNealy, 1999 Microsoft Faculty Summit, August 2004 –Rick Rashid: People don’t even know what “privacy” means. –Bill Gates: Things are going to get worse. Google, Microsoft, and Yahoo! are all trying “to personalize search.”

6. 6 Sample Highlights of the Next 3.5 Years (1) Work with more user communities on PPDM. –Genetics researchers (see Schäffer’s White Paper) –We could use help from NSF on this! Deal with adversarial behavior in massive-graph computations and massive-matrix computations. ?Computational realization of contextual integrity (or proof that there is none) Experimental analysis of “public-records” policies

7. 7 Sample Highlights of the Next 3.5 Years (2) Privacy-preserving data cleaning Privacy-respecting personalized search ― Policy-driven search in a social network ― Enterprise-wide policy-driven search Countering emerging threats to identity protection (e.g., bot-nets) Compliance-testing tools ― Health data: HIPAA ― Financial data: SB1386, Sarbanes Oxley
