This thesis examines the legal means by which the Swedish government authorities can outsource personal data to be processed on digital clouds by private cloud providers as of May 25th, 2018. The objective of the thesis is to identify and examine to which extent legal obstacles and restrictions to such procedures occurs in the personal data protection regulation. Cloud computing is an information technology business model which could provide government au-thorities with higher administrative efficiency and lower administrative costs. The essential charac-teristics of cloud computing require that the cloud providers are entrusted with a portion of control of the IT-environment and data security, depending on the types of clouds and services provided. The thesis analyses particularly two questions. The first question is to which extent the legal require-ment to provide personal data with an appropriate level of security constrains government authori-ties to submit control of the IT-environment to private contractors. The second question targeted in the thesis is whether government authorities can disclose personal data that is subjected to official secrecy to the cloud providers.
