  The upcoming Beyond 5G (B5G) and 6G networks are expected to provide enhanced
capabilities such as ultra-high data rates, dense connectivity, and high
scalability. It opens many possibilities for a new generation of services
driven by Artificial Intelligence (AI) and billions of interconnected smart
devices. However, with this expected massive upgrade, the privacy of people,
organizations, and states is becoming a rising concern. The recent introduction
of privacy laws and regulations for personal and non-personal data signals that
global awareness is emerging in the current privacy landscape. Yet, many gaps
need to be identified in the case of two data types. If not detected, they can
lead to significant privacy leakages and attacks that will affect billions of
people and organizations who utilize B5G/6G. This survey is a comprehensive
study of personal and non-personal data privacy in B5G/6G to identify the
current progress and future directions to ensure data privacy. We provide a
detailed comparison of the two data types and a set of related privacy goals
for B5G/6G. Next, we bring data privacy issues with possible solutions. This
paper also provides future directions to preserve personal and non-personal
data privacy in future networks.
