Apple recently updated its privacy policy, making clear that, unlike other companies (Hi, Google, Facebook,…!), in many cases it cannot or does not access your personal data. At the same time, in an open letter, its CEO Tim Cook states

Our business model is very straightforward: We sell great products. We don’t build a profile based on your email content or web browsing habits to sell to advertisers. We don’t “monetize” the information you store on your iPhone or in iCloud. And we don’t read your email or your messages to get information to market to you. Our software and services are designed to make our devices better. Plain and simple.

Even though I believe this is a very significant step, improving the privacy of ordinary users worldwide, it’s only a first step on a long trip to properly protect our privacy.

I’m not only a computer scientist specialising in privacy enhancing technologies. I also enjoy playing music. In fact I play several instruments, among which the bassoon (which is quite a weird choice of instrument to play considering the music I like, but I digress…). Over the years I’ve compiled several fingering charts. Below you find the fingering charts for flageolet/dual tones.

People that know me know I’m a Tablet PC fan. I love to be able to annotate pdf’s by writing in the margins with a pen. And I really like One Note for writing down my meeting notes or research ideas. It’s great for math, flow charts, etc. It’s the only reason I still use Microsoft (if only Apple would …, but I digress). I recently got a Lenovo Helix. But I had huge problems with calibration of the pen. Here is how I solved it.

Jumbo en Polare overwegen jou als klant in hun winkel te volgen met behulp van je eigen smartphone. Zo kunnen ze precies in kaart brengen hoe vaak je in de winkel komt, welke route je in de winkel volgt (loop je iedere keer langs de schappen met wijn?), en hoe lang je bij bepaalde producten stilstaat (twijfel je over de aanschaf van een bepaald tijdschrift?). Dit idee legt twee fundamentele problemen bloot.

Privacy by design requires that privacy concerns are tackled throughout the full life cycle of system development. In this paradigm, privacy protection is a system requirement like any other functional requirement, that must be addressed from the beginning, and that shapes the final design and implementation of the system. To support privacy by design, we therefore need guiding principles to resolve privacy requirements throughout the system development life cycle, in particular during concept development, analysis, design and implementation phases. To this end, this blog post (and the accompanying full paper)
presents eight privacy design strategies. Read the rest of this entry »
