    The Evolution of Embedding Metadata in Blockchain Transactions

    The use of blockchains is growing every day, and their utility has greatly expanded from sending and receiving crypto-coins to smart-contracts and decentralized autonomous organizations. Modern blockchains underpin a variety of applications: from designing a global identity to improving satellite connectivity. In our research we look at the ability of blockchains to store metadata in an increasing volume of transactions and with evolving focus of utilization. We further show that basic approaches to improving blockchain privacy also rely on embedding metadata. This paper identifies and classifies real-life blockchain transactions embedding metadata of a number of major protocols running essentially over the bitcoin blockchain. The empirical analysis here presents the evolution of metadata utilization in the recent years, and the discussion suggests steps towards preventing criminal use. Metadata are relevant to any blockchain, and our analysis considers primarily bitcoin as a case study. The paper concludes that simultaneously with both expanding legitimate utilization of embedded metadata and expanding blockchain functionality, the applied research on improving anonymity and security must also attempt to protect against blockchain abuse.Comment: 9 pages, 6 figures, 1 table, 2018 International Joint Conference on Neural Network

    Privacy and Health Information Technology

    The increased use of health information technology (health IT) is a common element of nearly every health reform proposal because it has the potential to decrease costs, improve health outcomes, coordinate care, and improve public health. However, it raises concerns about security and privacy of medical information. This paper examines some of the “gaps” in privacy protections that arise out of the current federal health privacy standard, the Health Insurance Portability and Accountability (HIPAA) Privacy Rule, the main federal law which governs the use and disclosure of health information. Additionally, it puts forth a range of possible solutions, accompanied by arguments for and against each. The solutions provide some options for strengthening the current legal framework of privacy protections in order to build public trust in health IT and facilitate its use for health reform. The American Recovery and Reinvestment Act (ARRA) enacted in February 2009 includes a number of changes to HIPAA and its regulations, and those changes are clearly noted among the list of solutions (and ARRA is indicated in the Executive Summary and paper where the Act has a relevant provision)

    Lex Informatica: The Formulation of Information Policy Rules through Technology

    Get PDF
    Historically, law and government regulation have established default rules for information policy, including constitutional rules on freedom of expression and statutory rights of ownership of information. This Article will show that for network environments and the Information Society, however, law and government regulation are not the only source of rule-making. Technological capabilities and system design choices impose rules on participants. The creation and implementation of information policy are embedded in network designs and standards as well as in system configurations. Even user preferences and technical choices create overarching, local default rules. This Article argues, in essence, that the set of rules for information flows imposed by technology and communication networks form a “Lex Informatica” that policymakers must understand, consciously recognize, and encourage
