- Two sets $A$ and $B$ have the *same cardinality*, written $|A| = |B|$, if there exists a bijective function $f : A \rightarrow B$. If not, the sets have *unequal ...
Abstract: In this paper we study the problem of estimating the cardinality of pairwise set operations (union and intersection) over sets possessed by different data owners, while preserving ...
This project demonstrates a simplified Zero-Knowledge proof using Noir for calculating the "cardinality" of the intersection between two private sets of fixed small size. A prover, knowing both sets, ...
