Abstract
Modern information technologies offer, at least in principle, many exciting opportunities - knowledge society (KS) inclusive. Practical results of KS are, however, substantially restricted by non-technical limitations, especially by the legislative bans on the use of existing data, on the data searching and collecting, and on the information and knowledge computed from them.
We show the consequences it has on the experience with use of a health related databases in Czech Republic. Czech system of health services produces a lot of data that could be used to supervise/monitor drug addictions, epidemic outbreak, quality of health procedures and medicaments, etc.
It is, however, forbidden by law. We propose a solution based on the existence of accredited bodies allowed to produce open information and open knowledge from sensitive data.
They should support processes of filtering and cleaning of the data and the filtering of queries so that only results not revealing sensitive data are produced.
