Protecting Cloud-Based Home e-Healthcare with Cryptographic Scheme

摘要

The emergence of ubiquitous technologies gives rise to huge applications that enable the data accessibility anytime anywhere. Cloud-based home healthcare system is one of researching area of the cloud computing applications. As cloud computing allow the on-demand network to a shared pool of configurable computing resources, patients' data protection is the paramount requirement for the security and privacy to ensure the trustworthiness of the cloud-based home healthcare system. To this end, this paper proposes cryptographic scheme where a patient can encrypt his data before uploading the data to the cloud. To achieve this, we design and implement a healthcare monitoring system to collect patient data and send them to computer. In this experiment we use pulse sensor on arduino board for heart rate measurement. The data collected from the patient can be uploaded to cloud after encryption operations. Only the user with shared private key can decrypt the patient data. Thus, the patient would trust in the cloud infrastructure that supports critical applications for the healthcare system. In addition, the analysis of the proposed scheme ensure the honesty of the cloud provider, since the patient has the ability to control who has access to his data by issuing a cryptographic access credential to data users.
