Cardiovascular disease is one of the deadliest diseases in the world. Accurate analysis and prediction for real-time heart disease are highly significant. To address this challenge, a novel IoT-based automated function monitoring system to promote the e-healthcare system is proposed. The proposed remote healthcare monitoring system uses an IoT framework (RHMIoT) using deep learning and auto encoder-based machine learning algorithms to accurately predict the presence of heart disease. The RHMIoT framework contains two phases: the first phase is to monitor the severity level of the heart disease patient in real-time, and the second phase is used in the medical decision support system to predict the accuracy level of heart disease. To train and test the open-access Framingham dataset, various deep learning and auto encoder-based machine learning techniques are used. The proposed system obtains an accuracy of 0.8714% using the auto encoder-based kernel SVM algorithm compared to other approaches.

E-commerce (electronic commerce) or EC is the buying and selling of goods and services, or the transmitting of funds or data, over an electronic network, primarily the internet. These business transactions occur either as b to b (business-to-business), b to c (business-to-consumer), c to c (consumer-to-consumer) or c to b (consumer-to-business).It is the trading or in products or services using computer networks like Internet or online social networks. Here the Business conducted through the use of computers, telephones, fax machines, barcode readers, credit cards, automated teller machines (ATM) or other electronic appliances without the exchange of paper-based documents or physically moving to a shopping mall. It includes activities such as procurement, order entry, transaction processing, online payment, authentication, inventory control, order fulfillment, shipment, and customer support. When a buyer pays with a bank card swiped through a magnetic-stripe-reader, he or she is participating in e-commerce. E-commerce Security is a part of the Information Security framework and is specifically applied to the components that affect ecommerce including of Data security and other wider realms of the Information Security framework. E-commerce security is the protection of e-commerce assets from unauthorized access, use, alteration, or destruction. Dimensions of e-commerce security-Integrity, Non-repudiation, Authenticity, Confidentiality, Privacy, Availability. Ecommerce offers the banking industry great opportunity, but also creates a set of new risks and vulnerability such as security threats, hackings. Therefore it is an essential management and technical requirement for any efficient and effective Payment transaction activities over the internet. Due to the constant technological and business change and requires a coordinated match of algorithm and technical solutions. In this paper we discussed with Overview of security for ecommerce, various steps to place an order, Security purpose in E-commerce, various security issues in E-commerce, guidelines for secure online shopping etc.
