Privacy As… Sharing More Information?

When I first started working in the area of personal privacy I had what I would call a conventional view on privacy, which is how to minimize the flow of information going out about them. I reasoned that people were private individuals, wanted protection from interruptions, and wanted a lot of control and feedback about what was shared.

Connecting the Two Ends: Mobile Clouds

  In 1959, the colorful and brilliant physicist, Richard Feynman, gave a seminal lecture to the American Physical Society entitled, "There's Plenty of Room at the Bottom," in which he considered the implications of matter manipulation at the atomic scale – a vision of then future nanotechnology. In computing, we also have plenty of room at the bottom, paradoxically enabled by plenty of room at the top. I speak, of course, of the transformative power of our now ubiquitous mobile devices and rich sensor/actuator networks (smart dust) coupled with the capabilities of immense cloud data centers. These two extremes of the modern computing scale are reshaping our society in deep and profound ways.

Computers For Public Schools

It's been a while since several Latin countries decided to start programs to deliver computers and to connect all public schools to the Internet providing access to technological resources to children through several initiatives.

Google Android Authentication

I recently saw a Google Android phone at HotMobile 2009 and was intrigued by the drawing-based authentication mechanism built in. Basically, there's a 3x3 grid of dots, and to log in, you simply use your finger and draw a pattern across these dots, using each dot at most once.

­Usable Privacy and Security

We are facing an increasing number of security failures, not because of problems with encryption algorithms, network protocols, or system implementations, but rather due to problems with the user interfaces of computer systems and the people that use those systems.

Compute For America

The United States certainly needs more and better computing educators, but that alone may not be enough to turn around declining enrollments in computing.

Shape the Future of Computing

ACM encourages its members to take a direct hand in shaping the future of the association. There are more ways than ever to get involved.

Get Involved

Communications of the ACM (CACM) is now a fully Open Access publication.

By opening CACM to the world, we hope to increase engagement among the broader computer science community and encourage non-members to discover the rich resources ACM has to offer.
