ABSTRACT
Cloud computing and social networks are changing the way of healthcare by providing realtime data sharing in a cost-effective manner. However, data security issue is one of the main obstacles to the wide application of mobile healthcare social networks (MHSNs), since health information is considered to be highly sensitive. In this paper, we introduce a secure data sharing and profile matching scheme for the MHSN in cloud computing. The patients can outsource their encrypted health records to cloud storage with an identity-based broadcast encryption technique, and share them with a group of doctors in a secure and efficient manner. We then present an attribute-based conditional data re-encryption construction which permits the doctors who satisfy the pre-defined conditions in the ciphertext to authorize the cloudplatform to convert a ciphertext into a new ciphertext of an identity-based encryption scheme for specialist without leaking any sensitive information. Furthermore, we provide a profile matching mechanism in the MHSN based on identity-based encryption with an equality test, which helps patients to find friends in a privacy-preserving way and achieves flexible authorization on the encrypted health records with resisting the keywords guessing attack. Moreover, this mechanism reduces the computation cost on the patient side. The security analysis and experimental evaluation show that our scheme is practical for protecting the data security and privacy in the MHSN.
INTRODUCTION
Mobile healthcare is an innovative combination of mobile devices and mobile communication technologies, for it can provide necessary health information, routine care improvements, potential infectious disease prevention, health interventions, etc. It is getting more and more widely to apply the emerging cloud computing technology into the fields of mobile healthcare. By using mobile healthcare system, the electronic health record (EHR) can be transmitted over the network to the cloud service provider (CSP) for remote storage. Moreover, the healthcare providers can read it from an end device or access it remotely using a mobile device to provide real-time medical treatment . Meanwhile, people tend to share and disseminate the healthcare information via social networks, since social media is an extension of the healthcare professional and patient relationship.
