“Overdisclosure“  privacy problems

Tools (technological and otherwise)  privacy solutions

Evaluation  validation of tools

Tool types à la SPION • Confidentiality • Control • Awareness of ... • „I am being tracked.“ • „which audiences do I have (whom I could give access)?“  e.g., FreeBu • „when I am thinking too small about this“

Please argue with me about • Let us not divide and conquer ourselves: • The standard (scientific ?!) distribution of work can be a dangerous self-blinding and continued delegation of responsibility when it comes to problems like privacy. • (Being forced to) being responsible is not only bad, but also part and parcel of being a human & a citizen. • We need awareness (tools), but we also need to build • true private spaces • true public spaces • “Privacy is not only about clicking Facebook.“
