Situational awareness platforms support the continuous observation of interest situations. In the eHealth context, SA can improve health services by assessing and interpreting patients' current situations. For instance, it allows the healthcare providers to recognize changes and abnormalities in the patient's condition and take the necessary actions. However, SA platforms still suffer from centralized management issues, such as availability, security, and privacy. This paper presents a blockchain-based approach for SA data processing to overcome these issues. Blockchain is a decentralized and distributed technology that also brings the advantage of flexible data custody. We evaluate our system through a case study and discuss the benefits and challenges of adopting Blockchain as a solution for eHealth.
