  Privacy-Preserving Cloud Computing is an emerging technology with many
applications in various fields. Cloud computing is important because it allows
for scalability, adaptability, and improved security. Likewise, privacy in
cloud computing is important because it ensures that the integrity of data
stored on the cloud maintains intact. This survey paper on privacy-preserving
cloud computing can help pave the way for future research in related areas.
This paper helps to identify existing trends by establishing a layered
architecture along with a life cycle and an ecosystem for privacy-preserving
cloud systems in addition to identifying the existing trends in research on
this area.
