  • What we do at DIG
    successful in blocking out unwanted viewers they are ineffective as privacy protection for a large decentralized system For a system like the World Wide Web once information is made publicly available it is easy to copy or aggregate data to infer sensitive information In a recent paper by Fuming Shih and Sharon Paradesi they demonstrate this exact problem through Global Inferencer a data miner that uses linked data technology to perform unified searches across Facebook Flickr and other public data sites Results reveal a startling amount of data about users based on inferences performed on individuals lifestyle and other behaviors Thus simply controlling access to personal information on individual social networking sites still exposes users to privacy risks It is difficult for users to protect their own privacy through existing tools and mechanisms because they find it challenging to specify privacy rules and have no way of expressing how they want their data to be used As the definition of privacy continues to evolve alongside novel ways of sharing and using data new systems are required in order to fully address the needs of users Enabling Information Accountability At DIG we are committed to the enabling of widespread deployment of a policy aware web a system that provides all users with accessible and understandable views of the policies associated with information resources The main motivation behind this as outlined in Section 2 0 is the lack of comprehensive effectiveness access control provides for information management As mentioned previously exclusive reliance on access restrictions leads to uncontrollable data usage once information is revealed In reality individuals are more interested in how data is used rather than how it is being accessed Information policies should be created to accompany data usage and accountability systems devised to reinforce proper compliance with these policies We have published several papers addressing the significance of policy awareness and the need to shift from access control to rule based access for the World Wide Web We specifically recognize the power of transparent accountable data mining and systems oriented towards information accountability instead of information security and access control The main contribution of accountable systems is the ability for decentralized systems to determine whether each use of data is permitted by the relevant rules specified by the author for that particular person in that particular circumstance Information accountability enhances privacy protection through transparency of data and deterrence Our goal at DIG is to enable real time detection and redress thereby inhibiting data misuse It is important to note that we are proposing information accountability as a complement instead of an alternative to access control While access control governs the disclosure and availability of information accountability enhances privacy protection through deterrence strategies similar to how legal and social rules work in our societies Even though most of these rules are not enforced perfectly or automatically citizens abide by them since our society evolved in a way such that compliance is encouraged over violation This can be illustrated in a

    world that is increasingly awash in information Examples include respecting personal privacy in social networks sharing information among government agencies and drawing valid results from online databases We re aiming to create a World Wide Web that is Policy Aware where information is accompanied by rules that govern its use and where automated reasoners detect if the use of the data complies with the rules We use techniques from Linked Data Semantic Web automated reasoning and parsing rules Some particular challenges are 1 Expressing policies in machine readable form 2 Extracting and combining information from independent sources like your Facebook page your Flickr page and your Tweets 3 Building automated reasoners that continue working when rules and facts change and are even contradictory 3 Expressing real policies such as actual laws in ways that the information can be interpreted by machines If you d like to work on these kinds of research problems send email to Marisol and come talk to us We are interested in working with students at all levels UROP MEng or PhD Please see our current UROP opportunities New to DIG For students who ve just joined DIG we recommend that you do the following Get a CSAIL account if you don t already have one Speak to Marisol about your paperwork to find out where you should sit and to get added to relevant mailing lists Ask our senior students about how to access our code repositories Attend weekly DIG Seminar currently scheduled on Tuesdays from 11am 12pm Read the following papers The Semantic Web Tim Berners Lee Jim Hendler and Ora Lassila Scientific American 2001 Information Accountability Daniel Weitzner Hal Abelson Tim Berners Lee Joan Feigenbaum Jim Hendler and Gerald Sussman Communications of the ACM 2008 Access Control is an Inadequate Framework for Privacy

    Learning computing by building mobile apps In December 2010 Google introduced App Inventor for Android a visual programming environment that makes it easy to create apps for Android phones Prof Abelson who worked on App Inventor during his sabbatical last year is planning to include the system in a new course this fall He s looking for help in developing good examples and creating extensions to the system maybe even teaching summer workshops for kids To work on this project you should have some experience with Python 6 00 or 6 01 and an interest in mobile apps and educational technology For more information see MIT Center for Mobile Learning http mitmobilelearning org Online Data Integration Using Semantic Web technologies The Semantic Web is a powerful distributed model for publishing utilizing and extending information and is sometimes referred to as Web 3 0 The contents of online Semantic Web data sources can be mashed up i e queried and integrated on the fly to provide rich Web applications However the user or application developer still needs to know exactly what data is present in each source and needs to formulate queries carefully in order to get a reply When the content of a source changes mashups users cannot take advantage of it until the application developer becomes aware of this change and modifies the application query accordingly In order to allow users to dynamically explore this space by asking open ended queries we intend to use the federation paradigm from database systems where federated data sources collaboratively attempt to solve a user s query In this project the student will learn about and use Semantic Web technologies extend our existing federation protocol and implement a use case A successfully implemented project could lead to support and or an MEng in
