UNSTRUCTURED Blockchain is an innovative decentralized ledger-based technology that was invented in 2008. Initial utilization was developed for the cryptocurrency bitcoin, but the utility of the technology extends well beyond just that of currency. Much of the value of blockchain exists in the revolutionary ability to transmit and validate data without a third party. Blockchain has significant room for utility in healthcare as a whole, with most of its potential still being very much untapped with the technology still in its incipience. Sleep medicine is an area of medicine that is particularly primed for implementation of blockchain, being a field immensely reliant on data transmission from technology in the form of sleep diagnostics, sleep-related consumer technologies, and therapeutic devices for clinical care to optimally function. Data exchange and entry points for logistics of diagnosis and management of sleep disorders is often fairly profuse and involving multiple parties, making blockchain technology particularly advantageous. Blockchain, like any technology, is not without its limitations, and more research and development is needed before it can be integrated to its potential. However, in blockchain exists the prospect of revolutionizing the way patients’ data interacts with the healthcare system as a whole as well as adjunctive systems which aid in conducting clinical care.

Bidding Process

In the field of modern bidding, electronic bidding leads a new trend of development, convenience and efficiency and other significant advantages effectively promote the reform and innovation of China’s bidding field. Nowadays, most systems require a strong and trusted third party to guarantee the integrity and security of the system. However, with the development of blockchain technology and the rise of privacy protection, researchers has begun to emphasize the core concept of decentralization. This paper introduces a decentralized electronic bidding system based on blockchain and smart contract. The system uses blockchain to replace the traditional database and uses chaincode to process business logic. In data interaction, encryption techniques such as zero-knowledge proof based on graph isomorphism are used to improve privacy protection, which improves the anonymity of participants, the privacy of data transmission, and the traceability and verifiable of data. Compared with other electronic bidding systems, this system is more secure and efficient, and has the nature of anonymous operation, which fully protects the privacy information in the bidding process.

Traditional voting and bidding systems largely rely on paperwork and human resources throughout the voting process, which can incur high costs in terms of both time and money. Electronic voting and electronic bidding systems can be used to reduce costs, and many new systems have been introduced. However, most systems require a powerful and trusted third party to guarantee system integrity and security. With developments in blockchain technology, research has begun to highlight the core concept of decentralization. In this study, we introduce the first decentralized electronic voting and bidding systems based on a blockchain and smart contract. We also use cryptographic techniques such as oblivious transfer and homomorphic encryptions to improve privacy protection. Our proposed systems allow voters and bidders to participate in the opening phase and improve participant anonymity, the privacy of data transmission, and data reliability and verifiability. Moreover, compared with other electronic voting and bidding systems, our systems are safer and more efficient.

Currently, sharing and access of medical imaging is a significant element of present healthcare systems, but the existing infrastructure of medical image sharing depends on third-party approval. In this chapter, the authors have proposed a framework in order to provide a decentralized storage model for medical image sharing through IPFS and blockchain technology that remove the hurdle of third-party dependency. In the proposed model, the authors are sharing the imaging and communications in medicine (DICOM) medical images, which consist of various information related to disease, and hence, the framework can be utilized in the real-time application of the healthcare system. Moreover, the framework maintains the feature of immutability, privacy, and availability of information owing to the blockchain-based decentralized storage model. Furthermore, the authors have also discussed how the information can be accessed by the peers in the blockchain network with the help of consensus. To implement the framework, they have used the python ask and anaconda python.

Abstract Objective: We sought to explore the technical and legal readiness of healthcare institutions for novel data-sharing methods that allow clinical information to be extracted from electronic health records (EHRs) and submitted securely to the Food and Drug Administration's (FDA's) blockchain through a secure data broker (SDB). Materials and Methods: This assessment was divided into four sections: an institutional EHR readiness assessment, legal consultation, institutional review board application submission, and a test of healthcare data transmission over a blockchain infrastructure. Results: All participating institutions reported the ability to electronically extract data from EHRs for research. Formal legal agreements were deemed unnecessary to the project but would be needed in future tests of real patient data exchange. Data transmission to the FDA blockchain met the success criteria of data connection from within the four institutions' firewalls, externally to the FDA blockchain via a SDB. Discussion: The readiness survey indicated advanced analytic capability in hospital institutions and highlighted inconsistency in Fast Healthcare Interoperability Resources format utilitzation across institutions, despite requirements of the 21st Century Cures Act. Further testing across more institutions and annual exercises leveraging the application of data exchange over a blockchain infrastructure are recommended actions for determining the feasibility of this approach during a public health emergency and broaden the understanding of technical requirements for multisite data extraction. Conclusion: The FDA's RAPID (Real-Time Application for Portable Interactive Devices) program, in collaboration with Discovery, the Critical Care Research Network's PREP (Program for Resilience and Emergency Preparedness), identified the technical and legal challenges and requirements for rapid data exchange to a government entity using the FDA blockchain infrastructure.

With the development of the Internet of Things and the demand for telemedicine, the smart healthcare system has attracted much attention in recent years. As a platform for medical data interaction, the smart healthcare system is demanded to ensure the privacy of both the receiver and the sender, as well as the security of data transmission. In this paper, we propose a privacy-preserving data transmission scheme where both secure ciphertext conversion and malicious users identification are supported. In particular, the OT m n protocol is introduced to guarantee the two-way privacy of communication parties. Meanwhile, we adopt proxy reencryption algorithm to support secure ciphertext conversion so as to ensure the confidentiality of data in many-to-many communication pattern. In addition, by taking advantage of the concept of blockchain technology, a novel OT m n protocol is proposed to prevent data from being tampered with and effectively identify malicious users. Theoretical and experimental analyses indicate that the proposed scheme is practical for smart healthcare with high security and efficiency.

Information sharing has become prevalent due to the expansion of social networking in this 21st century. However, electronic devices are vulnerable to various kinds of attacks. Information might be disclosed, modified and accessed by an unauthorised third party which consequently leads to the breach of confidentiality, integrity and availability of the information. Therefore, it is of utmost importance to employ the technology of cryptography and steganography to protect information assets. Cryptography and steganography have weaknesses when they are working alone. Therefore, crypto-steganography, the combination of cryptography and steganography are introduced to overcome the weaknesses in order to provide a double layer of security and protection. This paper provides a general overview of steganography and cryptography as well as a comparison analysis of different crypto-steganographic schemes. A secure crypto-steganographic system for healthcare is then developed with the implementation and integration of the secure crypto-steganographic scheme proposed by Juneja and Sandhu. This healthcare system enables users to store and deliver message in a more secure way while achieving the main goals of both cryptography and steganography.

Global Player

India has emerged as a global player for pharmaceuticals. The pharmaceutical revolution of 1970-90 of Indian Pharma Industry had demonstrated that India could be self-sufficient in the manufacture of essential drugs at affordable prices. The turnover of Indian Pharmaceutical is over $30 billion in 2015 including $15 billion in exports.  It was a great honor to preside the 67th Indian pharmaceutical congress held in Mysore. The topic of Pharmacists for a Healthy India is close to my heart and being a regulator myself, I feel that the Pharmacy fraternity can play a much larger role in contributing to the healthcare system in India. Pharmacist as such are involved in a big way in the regulation of drugs, be it manufacture, be it sale or research and development. A contribution of the Pharmacists is there at every stage till the drug reaches the consumer safely. For this purpose, the society needs a pool of well qualified and experienced pharmacists, which requires regular updating of their knowledge to keep pace with the developments taking place in the pharmaceutical sector. The advancements in technology and the emerging challenges in the health sector require pharmacists to shoulder the responsibilities towards the utilization of scientific knowledge in the use of modern medicines and the protection of the public against dangers of wrong use of drugs. The Pharmacy Council of India on its part will have to ensure that the courses offered for creating a high technology based are calibrated in such a way that the education and skills developed suit to the requirements of the Pharmaceutical Industry as well as needs to the patients
