Technological innovation and breakthroughs in Android and IoS operating systems have made our daily life to be centered on the smart phones. The measure of success of mobile technologies and its applications is based on its ability to meet the needs of individuals within an entire population including visually impaired people. The creative innovation in current Mobile Technology allows Mobile Apps to be efficiently distributed and run on Mobile devices.Such as Text-to-Speech, navigation assistance, object identification, color identification, speech recognitions facilities are integrated with basic mobile services. It also providing the user-friendly user interfaces which includes fully automated speech recognition system for support of visually impaired users. Hence, the aim of this paper is to focus on surveying the latest developments in mobile technologies and mobile apps which are targeted at bringing back the zest and joy in the life of visually impaired people. Using the overview gained over this study, an agenda is proposed for future research work in mobile application and interaction design with respect to visually impaired and blind users.
Currently available modern medical system generates large amounts of data, such as computerized patient data and digital medical pictures, which must be kept securely for future reference. Existing storage technologies are not capable of storing large amounts of data efficiently. It is a key and abrogating topic of specialized, social, and medical significance and a key and abrogating subject of general interest. The results of cars, purchasers, and Internet of Things industrybased and essential segments, sensors, and other daily objects are fused with a network of the Internet and solid information abilities that promise to alter the way we operate and live future. The suggested work demonstrates a symmetric-key lightweight technique for secure data transmission of images and text, which uses an image encryption system and a reversible data hiding system to demonstrate the program's implementation. On the other hand, cloud storage services can meet demand due to features such as flexibility and availability. Cloud computing is enabled by amazing internet innovation as well as cutting-edge electrical equipment. Even though medical images may be stored on the cloud, most cloud service providers only save client data in plain text. As part of their overall strategy, cloud users must take responsibility for protecting medical data. Because attackers' increasing computing power and creativity are opening up more and more areas in this mathematical form, most existing image encryption schemes are vulnerable to the plaintext attack of choice. This article presents an image encryption method inspired by an Adaptive IoT-based Hopfield Neural Network (AIHNN) that can resist other assaults while optimizing and improving the system through continuous learning and updating.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
