Dmail enters ring for making users feel like they have control of their email

Dmail is now in the Chrome store. Delicious Science, which last year acquired social bookmarking service Delicio.us, has released this Chrome extension that provides Gmail messages with the ability to self-destruct.

After installing the extension, Gmail users can send a message to anyone, whether or not that person uses the Dmail extension, and configure the message to deny access after a period of an hour, a day, a week, or never. In addition, a “Revoke Access” button provides a way to immediately disable access to a protected message.

If the recipient has the Dmail extension, he or she can read the message in Gmail until it expires or is revoked. Dmail has designed the extension so that the neither Gmail nor Dmail servers ever receive both the decryption key and encrypted message. Only the recipient and sender can read the email legibly.

The accessibility of Dmail’s source code — Chrome extensions are just collections of JavaScript, HTML, and image files — may help security skeptics decide whether or not to trust Dmail. The software relies on Gibberish-AES, a JavaScript library for OpenSSL-compatible AES CBC encryption.

However, the presence of JavaScript modules for tracking and analytics suggests this software isn’t intended for people who want serious security; rather, it appears to be aimed at people who would like to feel they have more control over their data than regular email affords.

Concerns about real security would include the relatively weak encryption being used in the package. A further question is what is yet the friction offered to authorities who seek the keys to a message from all of the parties involved. But the package has addressed accessibility concerns with the wider community.

Several sites dark for SOPA protests

Today is the day that sites have banded together to raise awareness about [SOPA and PIPA legislation](https://www.eff.org/deeplinks/2012/01/january-18-internet-wide-protests-against-blacklist-legislation). There are two bills, SOPA in the House and PROTECT IP ACT (PIPA) in the Senate. Important sites have gone dark, at least on their logos, as a way of raising awareness and protesting the potential legislation. Continue reading Several sites dark for SOPA protests

More from the Master Switch

I [wrote](http://seanmehan.globat.com/blog/2011/06/10/the-minimal-energy-well-of-accepted-thought/) the other day about some thoughts about local energy minima as a function of innovation, sparked by Timothy Wu’s *The Master Switch*, one of my current reads. I wanted to capture a fabulous quote and story about one of the iterations of Wu’s *cycle*, dealing with the *radio telephone*. Continue reading More from the Master Switch

Where forward for UHI VC From HD 1080p?

So, here at [UHI](http://www.uhi.ac.uk/) we are just finishing installing a refresh of our entire VC infrastructure, which we depend upon in a critical fashion. We have the highest number of [1080p](http://bit.ly/axHAiK) capable codecs deployed in any HEI in Britain, if not the world, since it fits our delivery model, and we use it to support the entire academic enterprise. But what is coming down the pipe for when we do this again in 5-7 years?
