A new integration of wireless communication technologies into the mobile heath system also known as mHealth has instigated a momentous research interest in the field of mobile security. mHealth systems are unique in terms of characteristics, challenges, architecture, and applications. Consequently, security requirements related to mHealth system are more complex as compared to mobile networks and conventional wireless networks. This article presents a survey about developments in mHealth system from the perspective of lightweight cryptographic protocols and privacy preserving algorithms. Unique characteristics of mHealth systems are presented which make the embedded security applications computationally hard as well as memory constrained. The current study also deals with the fundamental security requirements, essential for mHealth communication. Furthermore, awareness of security threats and their cryptographic solutions in terms of future health industry are discussed. In addition, lightweight cryptographic solutions are summarized. These strategies can be enhanced or incorporated all in all to meet the security perquisites of future patients' data security.

The use of information communication technologies (ICTs) in therapy offers new perspectives for treating many domains in individuals with autism spectrum disorders (ASD) because it is used in many different ways and settings and they are attractive to the patients. Students with autism have a high incidence of visual perception problems. They often have difficulty recognizing, remembering, organizing and interpreting visual images. As a result, they are easily confused in situations where written or pictorial symbols are utilised for learning. The paper reported the design and development of autism diagnostic tool using serious games technique. It is a tool for special education teachers to diagnose visual perception problems among autistic students. The game is known as Vi-Per Games. A diagnostic tool known as Vi-Per Games has been developed based on ADDIE model. Vi-Per Games is able to diagnose autistic students without the needs for teachers to have some experience and knowledge of diagnosing visual perception. This prototype will be a high-tech solution to diagnose visual perception problems designed for autistic children.

Early identification and diagnosis of autism is the key to minimize its negative effects and get the autistic children on the right path. This paper analyzed autism diagnostic tool using serious games technique namely Vi-Per Games. It is a tool for special education teachers to diagnose visual perception problems among autistic students. The development of the game is based on ADDIE model. The results show that the use of Vi-Per Games successfully assist and facilitate teachers when making a diagnosis of visual perception problems in autistic students, compared with conventional methods of diagnosis. Diagnosing visual perception problems using serious games gives teachers and students enjoyable experiences in a way that no other medium can offer.
