  Self-Sovereign Identity (SSI) is projected to become part of every person's
life in some form. The ability to verify and authenticate that an individual is
the actual person they are purported to be along with securing the personal
attributes could have wide spread implications when engaging with third party
organizations. Utilizing blockchains and other decentralized technologies, SSI
is a growing area of research. The aspect of securing personal information
within a decentralized structure has possible benefits to the public and
private sectors. In this paper, we describe the SSI framework architecture as
well as possible use cases across domains like healthcare, finance, retail, and
government. The paper also contrasts SSI and its decentralized architecture
with the current widely adopted model of Public Key Infrastructure (PKI).
