Towards Trusted eHealth Services in the Cloud

As adoption of eHealth solutions advances, new computing paradigms - such as cloud computing - bring the potential to improve efficiency in managing medical health records and help reduce costs. However, these opportunities introduce new security risks which can not be ignored. In this paper, we present a forward-looking design for a privacy-preserving eHealth cloud system. The proposed solution, is based on a Symmetric Searchable Encryption scheme that allows patients of an electronic healthcare system to securely store encrypted versions of their medical data and search directly on them without having to decrypt them first. As a result, the proposed protocol offers better protection than the current available solutions and paves the way for the next generation of eHealth systems.
