The progress of information technology, especially the Internet, has created great advantages, but on the other hand, its incorrect use or abuse can have negative consequences in the economic – social and cultural environment, and sometimes can cause the destabilization of the whole society. The potential of information and communication technology for storing and processing personal data increases the problem of their protection.
We live in a time when personal data is increasingly exchanged between different authorities and institutions and transferred across state borders. That is why it is necessary to ensure the security of the entire system, to raise the awareness of the Internet – users about the numerous dangers that “sneak”, as well as to teach them not to “fall” for hacker games.
