Similarity search is a fundamental algorithmic primitive, widely used in many computer science disciplines. Given a set of pointsSand a radius parameterr> 0, ther-near neighbor (r-NN) problem asks for a data structure that, given any query pointq, returns a pointpwithin distance at mostrfromq.In this paper, we study ther-NN problem in the light of individual fairness and providing equal opportunities: all points that are within distancerfrom the query should have the same probability to be returned. The problem is of special interest in high dimensions, whereLocality Sensitive Hashing(LSH), the theoretically leading approach to similarity search, does not provide any fairness guarantee. In this work, we show that LSH-based algorithms can be made fair, without a significant loss in efficiency. We propose several efficient data structures for the exact and approximate variants of the fair NN problem. Our approach works more generally for sampling uniformly from a sub-collection of sets of a given collection and can be used in a few other applications. We also carried out an experimental evaluation that highlights the inherent unfairness of existing NN data structures.
