Web-connected door control

You know what would be very convenient? If the door to your home had an RFID card reader so that it could be programmed to let in anyone with a particular card. You could give houseguests a few days worth of access, without having to worry about getting keys back from them.

Because it would be web-connected, you could authorize people to have access to your home remotely. You could even have an option for unlocking the door through a web interface – for instance, in order to let a repairperson into your place.

There would need to be good security all along the line, from the radio communication between the RFID cards and the reader to the communication between the door control system and you via the web. Rather than try to achieve that though proprietary means, it would be better to publish all the hardware plans and software code and let people spot weaknesses that could then be fixed.

In the spring of 2005, I graduated from the University of British Columbia with a degree in International Relations and a general focus in the area of environmental politics. In the fall of 2005, I began reading for an M.Phil in IR at Wadham College, Oxford. Outside school, I am very interested in photography, writing, and the outdoors. I am writing this blog to keep in touch with friends and family around the world, provide a more personal view of graduate student life in Oxford, and pass on some lessons I've learned here.
