General Data Protection Regulation or GDPR: enforcement date – 25 May 2018. The GDPR covers the matter of online user data privacy rules for electronic communication and data protection. The regulation includes modern communication messengers and services, eg. Skype, Viber, Gmail, etc., that have not been previously mentioned in the former EU e-communication directives.
“Privacy is guaranteed for content of communication as well as metadata (e.g. time of a call and location) which have a high privacy component and need to be anonymised or deleted if users did not give their consent, unless the data is needed for billing.”
