Following strong regulations such as the European General Data Protection Regulation (GDPR), privacy protection in the financial sector has recently emerged as an urgent issue …
It is shown that if the Boolean hierarchy (BH) collapses, then there exists a sparse set S such that co-NP⊆NP^S, and therefore the polynomial time hierarchy (PH) collapses to …
