Existing fine-grained and secure access control systems deployed in mobile cloud computing (MCC) typically focus on offloading encryption and/or decryption workloads to the delegated proxy in the cloud server. However, the privacy and authenticity management of outsourced data with flexible and efficient access policy update in MCC is generally overlooked by existing works. In fact, the signcryption feature is generally required in data access control system where the trust between data owner and multiple mobile users is crucial while the policy update management deals with the dynamic handling of user privilege control lifecycle. In this paper, we propose a privacy-preserving access control scheme supporting signcryption and efficient policy update with policy hiding in MCC setting. Essentially, a fully outsourced attribute-based signcryption (ABSC) and policy update method are devised to allows the data owner to offload ABS operation and policy update cost to be executed by the delegated proxy. Finally, we present our experiments to demonstrate that our proposed scheme is computationally more efficient compared to related works.

“…For secured data management, an IPFS system was utilized. The application of blockchain technology in combination with heterogeneous signcryption with proxy re-encryption (HSC-PRE) has been proposed for secured data encryption and management [ 17 ]. Two main attributes of HER, interoperability and confidentiality of data, have been addressed in that work.…”

Background: The modern era of human society has seen the rise of a different variety of diseases. The mortality rate, therefore, increases without adequate care which consequently causes wealth loss. It has become a priority of humans to take care of health and wealth in a genuine way. Methods: In this article, the authors endeavored to design a hospital management system with secured data processing. The proposed approach consists of three different phases. In the first phase, a smart healthcare system is proposed for providing an effective health service, especially to patients with a brain tumor. An application is developed that is compatible with Android and Microsoft-based operating systems. Through this application, a patient can enter the system either in person or from a remote place. As a result, the patient data are secured with the hospital and the patient only. It consists of patient registration, diagnosis, pathology, admission, and an insurance service module. Secondly, deep-learning-based tumor detection from brain MRI and EEG signals is proposed. Lastly, a modified SHA-256 encryption algorithm is proposed for secured medical insurance data processing which will help detect the fraud happening in healthcare insurance services. Standard SHA-256 is an algorithm which is secured for short data. In this case, the security issue is enhanced with a long data encryption scheme. The algorithm is modified for the generation of a long key and its combination. This can be applicable for insurance data, and medical data for secured financial and disease-related data. Results: The deep-learning models provide highly accurate results that help in deciding whether the patient will be admitted or not. The details of the patient entered at the designed portal are encrypted in the form of a 256-bit hash value for secured data management.
