  With the advent of Bitcoin and blockchain, the growth and adaptation of
cryptographic features and capabilities were quickly extended to new and
underexplored areas, such as healthcare. Currently, blockchain is being
implemented mainly as a mechanism to secure Electronic Health Records (EHRs).
However, new studies have shown that this technology can be a powerful tool in
empowering patients to control their own health data, as well for enabling a
fool-proof health data history and establishing medical responsibility. With
the advent of mobile health (m-Health) sustained on service-oriented
architectures, the adaptation of blockchain mechanisms into m-Health
applications creates the possibility for a more decentralized and available
healthcare service. Hence, this paper presents a review of the current security
best practices for m-Health including blockchain technologies in healthcare.
Moreover, it discusses and elaborates on identified open-issues and
potentialities regarding the uses of Blockchain. Finally, the paper proposes
conceptual solutions for future blockchain implementations for m-Health
Services and Applications.
