A security services for internet of thing smart health care solutions based blockchain technology

Abstract

Pervasive and ubiquitous computing has enabled people better integrate physical things into the digital world. The internet of things (IoT) has been considerably more widely used in business and everyday life in the last decade. Innovative healthcare information and communication technologies are a vast field of research and applications that need IoT benefits, including speed, security, and low cost. The proposed modified advanced encryption standard (AES)-cipher block chaining (CBC)-based blockchain technology offers a shared key to devices that need to communicate directly with or with entities outside the smart healthcare network to give users greater control over transactions. The experiments are carried out using a Raspberry Pi 3, whereas two different sensors are employed in this case. Blockchain technology encrypts data between doctor and patient with varied user numbers. The results from experiments revealed that the proposed modified AES-CBC based blockchain technology could provide the IoT application with security services (confidentiality, integrity, and access control) with efficient execution time.

A survey on security and policy aspects of blockchain technology

“…A user's data sits in an off-blockchain storage and permissions related to access of this data by any sort of third parties is set by a user by making a transaction to the blockchain. This way the data access information for a piece of user data is mined in a distributed and trusted manner in a block of a blockchain as mentioned in [37]. Such as an access control system provides long chain for blockchain for the owners of the data to either modify or completely revoke the permissions related to their data.…”

“…This set should be modifiable on the go with the extreme case of this set being empty, i.e., a user can revoke a service/application's right to access her data at any time she wants. Figure 5 shows the blocks that have been created by encryption and Figure 6 shows the secure hash algorithm works on choosing the longest chain with hash function [37]. Figure 7 shows the secure hash algorithm works on choosing the longest chain with hash function [38] and Figure 8 show an example of secure hashing being performed on text [39].…”

Blockchain based drug supply chain for decentralized network

“…This allows us to focus on both the healthcare and supply chain industries and draw inspiration from them. The use of blockchain allows a secure ledger to record all transactions of goods and materials in the chain [24]- [26]. The paper is organized in the four sections.…”

An Internet of Things-based Automatic Medicine Consumption Reminder Box

“…Still, not many people who should consume drugs regularly neglect to consume drugs because much work must be done at work or at home [3]. In the problem, the author wants to create a system that will schedule the consumption of drugs with a schedule and medicines that must be consumed [4] [5].…”
