Regulating Data as Property: A New Construct for Moving Forward

The global community urgently needs precise, clear rules that define ownership of data and express the attendant rights to license, transfer, use, modify, and destroy digital information assets. In response, this article proposes a new approach for regulating data as an entirely new class of property. Recently, European and Asian public officials and industries have called for data ownership principles to be developed, above and beyond current privacy and data protection laws. In addition, official policy guidances and legal proposals have been published that offer to accelerate realization of a property rights structure for digital information. But how can ownership of digital information be achieved? How can those rights be transferred and enforced? Those calls for data ownership emphasize the impact of ownership on the automotive industry and the vast quantities of operational data which smart automobiles and self-driving vehicles will produce. We looked at how, if at all, the issue was being considered in consumer-facing statements addressing the data being collected by their vehicles. To formulate our proposal, we also considered continued advances in scientific research, quantum mechanics, and quantum computing which confirm that information in any digital or electronic medium is, and always has been, physical, tangible matter. Yet, to date, data regulation has sought to adapt legal constructs for “intangible” intellectual property or to express a series of permissions and constraints tied to specific classifications of data (such as personally identifiable information). We examined legal reforms that were recently approved by the United Nations Commission on International Trade Law to enable transactions involving electronic transferable records, as well as prior reforms adopted in the United States Uniform Commercial Code and Federal law to enable similar transactions involving digital records that were, historically, physical assets (such as promissory notes or chattel paper). Finally, we surveyed prior academic scholarship in the U.S. and Europe to determine if the physical attributes of digital data had been previously considered in the vigorous debates on how to regulate personal information or the extent, if at all, that the solutions developed for transferable records had been considered for larger classes of digital assets. Based on the preceding, we propose that regulation of digital information assets, and clear concepts of ownership, can be built on existing legal constructs that have enabled electronic commercial practices. We propose a property rules construct that clearly defines a right to own digital information arises upon creation (whether by keystroke or machine), and suggest when and how that right attaches to specific data though the exercise of technological controls. This construct will enable faster, better adaptations of new rules for the ever-evolving portfolio of data assets being created around the world. This approach will also create more predictable, scalable, and extensible mechanisms for regulating data and is consistent with, and may improve the exercise and enforcement of, rights regarding personal information. We conclude by highlighting existing technologies and their potential to support this construct and begin an inventory of the steps necessary to further proceed with this process

How to avoid repetitions in lattice-based deniable zero-knowledge proofs

Interactive zero-knowledge systems are a very important cryptographic primitive, used in many applications, especially when deniability (also known as non-transferability) is desired. In the lattice-based setting, the currently most efficient interactive zero-knowledge systems employ the technique of rejection sampling, which implies that the interaction does not always finish correctly in the first execution; the whole interaction must be re-run until abort does not happen. While repetitions due to aborts are acceptable in theory, in some practical applications it is desirable to avoid re-runs for usability reasons. In this work we present a generic technique that departs from an interactive zero-knowledge system (that might require multiple re-runs to complete the protocol) and obtains a 3-moves zero-knowledge system (without re-runs). The transformation combines the well-known Fiat-Shamir technique with a couple of initially exchanged messages. The resulting 3-moves system enjoys honest-verifier zero-knowledge and can be easily turned into a fully deniable proof using standard techniques. We show some practical scenarios where our transformation can be beneficial and we also discuss the results of an implementation of our transformation.Preprin

Molecular Structure and Modeling of Water-Air and Ice-Air Interfaces Monitored by Sum-Frequency Generation.

From a glass of water to glaciers in Antarctica, water-air and ice-air interfaces are abundant on Earth. Molecular-level structure and dynamics at these interfaces are key for understanding many chemical/physical/atmospheric processes including the slipperiness of ice surfaces, the surface tension of water, and evaporation/sublimation of water. Sum-frequency generation (SFG) spectroscopy is a powerful tool to probe the molecular-level structure of these interfaces because SFG can specifically probe the topmost interfacial water molecules separately from the bulk and is sensitive to molecular conformation. Nevertheless, experimental SFG has several limitations. For example, SFG cannot provide information on the depth of the interface and how the orientation of the molecules varies with distance from the surface. By combining the SFG spectroscopy with simulation techniques, one can directly compare the experimental data with the simulated SFG spectra, allowing us to unveil the molecular-level structure of water-air and ice-air interfaces. Here, we present an overview of the different simulation protocols available for SFG spectra calculations. We systematically compare the SFG spectra computed with different approaches, revealing the advantages and disadvantages of the different methods. Furthermore, we account for the findings through combined SFG experiments and simulations and provide future challenges for SFG experiments and simulations at different aqueous interfaces

Breaking the Constitutional Deadlock: Lessons from Deliberative Experiments in Constitutional Change

This work provides comparative insights into how deliberation on proposed constitutional amendments might be more effectively pursued. It reports on a new nationwide survey of public attitudes to constitutional reform, examining the potential in Australia of innovative Canadian models of reform led by Citizens' Assemblies. Assembly members are selected at random and are demographically representative of the wider public. They deliberate over reforms for several months while receiving instruction from experts in relevant fields. Members thus become 'public-experts': citizens who stand in for the wider public but are versed in constitutional fundamentals. The author finds striking empirical evidence that, if applied in the Australian context, public trust would be substantially greater for Citizens' Assemblies compared with traditional processes of change. The article sets these results in context, reading the Assemblies against theories of deliberative democracy and public trust. One reason for greater public trust in the Assemblies' may be an ability to accommodate key values that are otherwise in conflict: majoritarian democratic legitimacy, on the one hand, and fair and well-informed (or 'deliberatively rational') decision-making, on the other. Previously, almost no other poll had asked exactly how much Australians trust in constitutional change. However, by resolving trust into a set of discrete public values, the polling and analysis in this work provide evidence that constitutional reform might only succeed when it expresses, at once, the values of both majoritarian and deliberative democracy
