Abstract-E-Health is a common term used for electronic health, where the services and systems provided include electronic health records, prescriptions, consumer health information, healthcare information systems, and so on. In this period of time, several patients have started to use e-health, considering the convenience of services delivered and cost reduction. The popularity has abruptly been increasing due to a wide range of services. From the system administrator's perspectives, not only protecting privacy of patients is considered a difficult task, but also building trust of patients in e-health. In this paper, a design of security framework for data privacy in e-Health system based on web service architecture is proposed. It is interesting to note that the approach proposed in this paper is not limited to eHealth system.

In the QR Code authentication technique, smartphone has become a great tool and played an important role in the authentication process. It has been used in various fields over the internet, especially in multi-factor authentication. However, security aspects should be well taken care of. In this paper, the performance comparison between RSA and Elliptic Curve Cryptography-based QR Code Authentication is proposed. It mainly focuses on QR Code, as it is now widely used all over the world. In addition, existing and related work has leveraged the use of RSA, but no work done on Elliptic Curve Cryptography. The experiment results and comparisons are shown and described in this paper.
