A novel and secure IoT based cloud centric architecture to perform predictive analysis of users activities in sustainable health centres

Diabetes, blood pressure, heart, and kidney, some of the diseases common across the world, are termed ’silent killers’. More than 50 % of the world’s population are affected by these diseases. If suitable steps are not taken during the early stages then severe complications occur from these diseases. In the work proposed, we have discussed the manner in which the Internet-of-Things based Cloud centric architecture is used for predictive analysis of physical activities of the users in sustainable health centers. The architecture proposed is based on the embedded sensors of the equipment rather than using wearable sensors or Smartphone sensors to store the value of the basic health-related parameters. Cloud centric architecture is composed of a Cloud data center, Public cloud, Private cloud, and uses the XML Web services for secure and fast communication of information. The architecture proposed here is evaluated for its adoption, prediction analysis of physical activities, efficiency, and security. From the results obtained it can be seen that the overall response between the local database server and Cloud data center remains almost constant with the rise in the number of users. For prediction analysis, If the results collected in real time for the analysis of physical activities exceed any of the parameter limits of the defined threshold value then an alert is sent to the health care personnel. Security analysis also shows the effective encryption and decryption of information. The architecture presented is effective and reduces the proliferation of information. It is also suggested, that a person suffering from any of the diseases mentioned above can defer the onset of complications by doing regular physical activities.

Design and Implementation of a Yoruba Language Crytosystem

Security has always been a bedrock for transaction and protection of human lives and until the existence of artificial intelligence, humans have learned to trust themselves for each other safety or safety of information except for few times where security was threatened by breach of trust or betrayal by persons which often led to enormous crisis. Recent research works have been able to achieve some high level of success in security of information. However, communication in Yoruba language using the Yoruba alphabet and symbols is still at its infancy. In other to achieve acceptable quality of information security of Yoruba alphabet and symbols in text, there is need for a robust security system. There are multiple layers of security, requirements and features which need automated technicality for assurance of effective security. In this paper, encryption and decryption of information written in Yoruba as text is  achieved using Caesar Cipher Algorithm to carry the Yoruba people along in the advancement taking place in the world of information technology. It adopted a symmetric encryption algorithm that uses one key for both encryption and decryption and used digits as its ciphertext which is a novel means of ensuring difficulty in breaking the codes as patterns with digits are not easily recognizable.

Synchronization of discrete-time hyperchaotic systems: An application in communications

In this paper, the synchronization problem of discrete-time complex dynamics is presented. In particular, we use the model-matching approach from nonlinear control theory to synchronize two unidirectionally coupled discrete-time hyperchaotic systems. A potential application to secure/private communication of confidential information is also given. By using different (hyperchaotic) encryption schemes with a single and two transmission channels, we show that output synchronization of hyperchaotic maps is indeed suitable for encryption, transmission, and decryption of information.

Encryption and decryption of information in chaotic communication systems governed by delay-differential equations

We consider different ways for encryption and decryption of information in communication systems using chaotic signal of a time-delay system as a carrier. A method is proposed for extracting a hidden message in the case when the parameters of the chaotic transmitter are a priori unknown. For different configurations of the transmitter the procedure of information signal extraction from the transmitted signal is demonstrated using numerical data produced by nonlinear mixing of the chaotic signal of the Mackey–Glass system and frequency-modulated harmonic signal.
