Mobile blockchain has achieved huge success with the integration of edge computing services. This concept, when applied in mobile crowd sensing, enables transfer of sensor data from blockchain clients to edge nodes. Edge nodes perform proof-of-work on sensor data from blockchain clients and append validated data to the chain. With this approach, blockchain can be performed pervasively. However, securing sensitive sensor data in a mobile blockchain (client/edge node architecture) becomes imperative. To this end, this paper proposes an integrated framework for mobile blockchain which ensures key agreement between clients and edge nodes using Elliptic Curve Diffie-Hellman algorithm. Also, the framework provides efficient encryption of sensor data using the Advanced Encryption Standard algorithm. Finally, key agreement processes in the framework were analyzed and results show that key pairing between the blockchain client and the edge node is a non-trivial process.
Females prefer discovering social media or healthcare systems to finding information and presenting their cases with any physician; however, the behavior of physicians tends to be uncontrollable on the healthcare system. Physicians have the capacity to share all of their patients' information with their colleagues without any permission or concern from the patients. For this reason, it is of utmost importance to design a breast self-examination system that can keep monthly track of self-exam data and communication between patient and physician. To develop such a system, identify the ethical values and trustworthiness as an indicator. Then, the survey will provide the details on ethical values and trustworthiness applicable in the system. Therefore, this research objective on the importance of ethical value and trustworthiness in the healthcare system. The survey on 772 respondents leading to the importance of the ethical value being used in the healthcare system is required. The ethical value of interaction, integrity, confidentiality, protection, caring, and fairness have a significant influence on the healthcare system. The path coefficients are answering Hypothesis I in presenting the positive relationship and significant effect between ethical value and BSE system (P<.001). On the other side, trustworthiness has a significant influence on the healthcare system. The path coefficients are answering Hypothesis II in presenting the positive relationship and significant effect between trustworthiness and the BSE system (P<.001). Finally, the relationship in healthcare between trustworthiness and ethical value is on integrity with honesty and belief.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
