The Red Matrix
Pair this with automatic "magic-auth" login across the matrix (using the same techniques that ad networks use against you, turned instead into an instrument of positive change). The end result is a web that knows who you are, but only as much about you as you wish to be known. Other websites can greet you by name. Content itself is aware of who is looking at it and can refuse to be viewed by this observer - or can alter itself accordingly.
Meanwhile all the power and control of privacy is in the hands of the content creator/publisher. This results in a unique network with extra-ordinary abilities built on top of the existing web using tools we have today.
Identity isn't restricted to a "person". Instead we provide the ability to create "channels" - which can function like social network identities (people), or like traditional forums (groups), or they can represent independent ideas or aspects of oneself. Each channel can link with any others for the purpose of communications. They can also combine to create derivative channels and even more complex structures. We tend to think of the matrix as a living organism in cyberspace which grows and learns as the channels which make it up combine and attach in different ways.
The commercial possibilities for this technology are endless. Imagine customer loyalty programs which don't require you to sign up on the vendor's website. But this can be a slippery slope so we built privacy and self-determination into the DNA of the matrix. It cannot be subverted by commercial exploitation.
Encrypted transport and storage of private communications is built-in. This can protect your communications against "most" rogue governments and "most" rogue service providers. Additionally, you can choose to further protect your communications using end-to-end encryption - again this is built in and available to anybody. Even higher level privacy modes are also available for those that require them. Typical darknets are lonely places because everybody is hiding both from each other and from external agents. The matrix (by contrast) appears on the outside to be not much different from the large centralised social providers, but when you wish something to be private, it can be locked with as many locks as you desire and sealed from everybody but the recipient(s).
The nomadic identity feature means you cannot be silenced even if your service provider is forcibly taken down by rogue agents. You can appear anywhere in the matrix with your identity and friends intact and continue on as if nothing happened.
Future developments are centered around integration with what we call the "legacy web" and better ease-of-use for creating websites for small businesses (we could use help from a few more front-end developers). Our access control is compatible with OpenID, which means you can make your files/images/events/bookmarks/webpages/etc. available to specific people anywhere on the internet - based on their having an OpenID. Unlike Red Matrix accounts, this will often require an extra authentication step. We also plan to provide social network integration with several web projects and services.
