Therefore, even if a hacker tries to get into a system but is unsuccessful they can be prosecuted using this law. The act also outlaws “hacking” software, such as packet sniffers, that can be used to break into or discover ways to get into systems.

Data protection is a type of privacy protection manifesting in special legal regulation. Data protection right ensures a person the right of disposal over all data in connection with his personality. This way it serves to sustain the protection of privacy in a world where the possibility of collecting, storing and conciliation of large pools of data is widely available.
Earlier, due to the lack of highly developed data-processing technologies no threat was imposed by a situation in which these data became public and known to others, while today processing, conciliation and association of data or creating new data relying on the old ones might result in the infringement to the right of privacy. The underlying notion behind the codification of data protection law is the insufficiency of secrecy protection: within the new context protection should apply to all data: “data protection should be differentiated from the interpretation of privacy as intimacy.
