In einer Diskussion rund um die Vorratsdatenspeicherung und die immer verstärkter aufkommende Videoüberwachung habe ich verschiedene Szenarien aufgezeigt. Ein Szenario davon war, dass man durch Data-Mining und diverse Web 2.0-Dienste immer gläserner wird. Und zwar muss man dafür gar nicht erst seine eigene Homepage ins Web stellen. […]
