A secured cloud‐medical data sharing with A‐BRSA and Salp ‐Ant Lion Optimisation Algorithm

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Sharing medical data among healthcare providers, researchers, and patients is crucial for efficient healthcare services. Cloud‐assisted smart healthcare (s‐healthcare) systems have made it easier to store EHRs effectively. However, the traditional encryption algorithms used to secure this data can be vulnerable to attacks if the encryption key

Shifting the reference point in environmental regulation: from polluter‐pays to beneficiaries‐compensate

The Scandinavian Journal of Economics, EarlyView.
Abstract In many environmental problems, emissions are hard to monitor and abatement costs are privately known. We study how efficient abatement nevertheless can be induced through market‐like arrangements that condition transfers on verifiable abatement rather than on measured emissions.
