Dr. Arvind Narayanan 308 Sherrerd Hall

Research areas: broadly, privacy and security. Especially online tracking and Bitcoin.

Some topics and questions I'm interested in:

1. What can be inferred about people based on publicly available online data?

If someone really wanted to find out personal things about you online, how far could they get? Let's investigate this by writing a bot which, given an identity (say, an email address), collects and aggregates information from various sites about that person. Ideally, it should be able to automatically figure out which information is current and which is out of date, reconcile conflicts, make new inferences based on multiple pieces of data, and hook into the "deep web" — pages that are not directly visible on web searches.

2. Reverse engineering the Web to expose poor security and privacy

Web companies track us online and compile extensive databases of our personal information. The personal behavioral profiles created through tracking are used for targeted advertising, price discrimination, targeted political emails, and various other practices that make people uncomfortable. I have an ongoing long-term project to automatically reverse engineer web trackers to determine what information companies have collected about you and what they are using it for. There are many interesting sub-projects to work on.

3. Various Bitcoin-related projects

Can we make a more secure Bitcoin wallet? Just how anonymous are Bitcoin users? Can we create an "early-warning system" that connects to a large number of P2P Bitcoin nodes and looks for signs of possible attacks on the security or stability of the system?

4. A streamlined privacy-alert system

Dozens of articles come out every month informing privacy-conscious users that they need to change some setting, install a tool, or otherwise take some action to protect their privacy. In particular, companies often release new features with permissive defaults and an opt-out setting. It seems that online privacy requires eternal vigilance.

Can we build a streamlined privacy-alert system that largely automates online privacy vigilance?

5. Classify and rank research blogs, set up aggregators

I run the Theory of Computing blog aggregator which is read by a significant fraction of the theory research community. It's a very efficient way to stay on top of the research conversation. I'd like to set one up on every research subtopic (and there are hundreds), but it is time-consuming.

But this can be automated! Here's how: 1. collect URLs of research blogs by programmatically exploring the web 2. use machine learning to group them into topics, and rank them by authority within topics 3. set up aggregators on each topic. This is a challenging project involving machine learning, large datasets and web programming, but potentially highly impactful.

Opportunities outside the department

We encourage students to look in to doing interdisciplinary computer science research and to work with professors in departments other than computer science. However, every CS independent work project must have a strong computer science element (even if it has other scientific or artistic elements as well.) To do a project with an advisor outside of computer science you must have permission of the department. This can be accomplished by having a second co-advisor within the computer science department or by contacting the independent work supervisor about the project and having he or she sign the independent work proposal form.

Here is a list of professors outside the computer science department who are eager to work with computer science undergraduates.
