This podcast interview focuses on product innovation that has the power to give us memorable experiences without having to give up our privacy. My guest is Ofer Tziperman, CEO AnagogHe has 20 years’ experience as an entrepreneur and leader of High Tech private and public companies. He served as the CEO of OTI, a leading developer of NFC-based payment solutions and as the CEO of Parx, a provider of on-street parking payment solutions. In 2000 Ofer co-founded LocatioNet Systems, a pioneer in the Location-Based Services market. In 2001 the World Economic Forum awarded him in Davos as ‘Technology Pioneer’. Ofer has an LLB Law degree from Tel-Aviv University.Today Ofer leverages his technology and management experience to drive Anagog’s long term success. Anagog is the developer of JedAI - a patented edge-AI technology that solves the conflicting dilemma of deeply understanding your customers behaviour, create moments of surprise and delight, all without harming their privacy.This inspired me, and hence I invited Ofer to my podcast. We explore the ever growing need for better experiences and the problems this creates around our privacy: everything we do is tracked and stored somewhere without being in control of it. We discuss the technology answers to this so that we can have the best of all worlds: Better experiences, more surprise and delight, without sharing anything. We also dig into how remarkable products often are the result of many pivots – and what leaders need to do different in order to succeed.Here are some of his quotes:‘Everybody trying to understand us, based on our online or digital life. And while 80% of the time we're actually spending in the real world. And we have full life in the real world. But it looks like the new technology is only trying to focus on what we are doing online.It looks like everybody in the attempt of trying to understand us in a more personal way. They forgot that we have private Life.We all feel a little bit uncomfortable with the question: “what exactly does Google know about me, or Apple, or Facebook? And at some point, some of us actually gave up.We are actually trying to roll it back and to say, “guys, there is an option that only our phone will know everything about you, and it will never leave your phone.” So, in a way, we try to change everything upside down.’During this interview, you will learn four things:That a major opportunity to truly understand your ideal customer is found in understanding what they do ‘off-line’Why transformation starts when we ask ourselves propelling questions that combine both a bold aspiration with a significant constraintHow we can make our solutions memorable by focusing less on fixing gaps, and more on creating peaks i.e. moments of surprise and delight.That opportunity starts when you manage to do something which is very difficult i.e. when others are not able to do that.

Over the last years it has become apparent that privacy issues become moreand more important when accessing data sources either on the Web or bydatabase management systems. That is, the user does not only want to hidethe query, but also the result of that query from others. In the past theproblem of querying a database privately was solved by organizational ratherthan by technical means.In this talk we describe the problem of querying databases privately moreformally and discuss existing solutions from the area of private informationretrieval (PIR). The lack of efficiency and scalability motivated us lookfor alternative approaches using a so called "secure co-processor" (built byIBM). We introduce a set of algorithms that take advantage of the (physical)properties of the co-processor and show which algorithms are necessary toguarantee privacy for database queries. In the last part of my talk Ibriefly describe our vision how to extend the current privacy approach tolocation-based services, in particular to moving objects such as vehicles(cars). About the speaker: Johann-Christoph Freytag is a full professor for databases and informationsystems (DBIS) at the Computer Science Department of theHumboldt-Universität zu Berlin, Germany. Before joining the department in1994 he was a research staff member at the IBM Almaden Research Center(1985-1987), a researcher at the European Computer-Industry-Research Centre(ECRC, in Munich, Germany, 1987-1989), and the head of Digital's (DEC)Database Technology Center (also in Munich, 1990-1993). He holds a Ph.D. inApplied Mathematics/Computer Science from Harvard University, MA.Dr. Freytag's research interests include all aspects of query processing andquery optimization in object-relational database systems, new developmentsin the database area (such as semi-structured data, data quality, databasesand security, Semantic Web), privacy in database systems, mobile systems andmobility, and applying database technology to applications such as GIS,genomics, and bioinformatics/life science. Dr. Freytag spent two sabbaticals at IBM Research and IBM Development (1997,2001) and was a regular visitor of Microsoft Research and the SQLServergroup, Redmond, as a research scientist (2002, 2005, 2007, 2008). In thelast years he received the IBM Faculty Award 4 times for collaborative workin the areas of databases, middleware, and bioinformatics/life science.

Gabriel Ghinita, Private Queries in Location Based Services: Anonymizers are not Necessary

CERIAS Security Seminar Podcast

Mobile devices equipped with positioning capabilities (e.g., GPS) can ask location-dependent queries to Location Based Services (LBS). To protect privacy, the user location must not be disclosed. Existing solutions utilize a trusted anonymizer between the users and the LBS. This approach has several drawbacks: (i) All users must trust the third party anonymizer, which is a single point of attack. (ii) A large number of cooperating, trustworthy users is needed. (iii) Privacy is guaranteed only for a single snapshot of user locations; users are not protected against correlation attacks (e.g., history of user movement).We propose a novel framework to support private location-dependent queries, based on the theoretical work on Private Information Retrieval (PIR). Our framework does not require a trusted third party, since privacy is achieved via cryptographic techniques. Compared to existing work, our approach achieves stronger privacy for snapshots of user locations; moreover, it is the first to provide provable privacy guarantees against correlation attacks. We use our framework to implement approximate and exact algorithms for nearest-neighbor search. We optimize query execution by employing data mining techniques, which identify redundant computations. Contrary to common belief, the experimental results suggest that PIR approaches incur reasonable overhead and are applicable in practice. About the speaker: Gabriel Ghinita is currently a Post-doctoral Research Associate with the Dept. of Computer Science, Purdue University. He holds a a PhD degree in Computer Science from the National University of Singapore. Gabriel's research interests focus on access control for collaborative environments, and privacy for spatial and relational data. In the past, he held visiting scientist appointments with the Hong Kong University, and the Chinese University of Hong Kong. Gabriel served as invited reviewer for prestigious conferences and journals, such as VLDB, ICDE, TKDE and ACM GIS.
