I spoke about my concerns with the continued belief in selective sharing. I argue at this TedX Bay Area talk that it is unwise to expect that digital information systems are capable of privacy or selective sharing. In other words, it is a dangerous myth to believe in a feature that in practice fails regularly and by design. In fact, it seems that it is practically impossible to create any digital information system that is secure.
In such a world we may want to reconsider our sharing practices, particularly if they were built on the idea of selective sharing. If any of your digital information is something you would rather not share publicly, you may want to rethink the idea that you can keep your information private.
If you are building an information system, you may want to rethink the idea that you can offer selective sharing in a reliable form.
Thanks to the folks at TedX Bay Area, particularly Tatyana Kanzaveli for the opportunity to work out these thoughts and share them.
Here are the slides that were used in the talk:
