A Privacy-Aware Protocol for Sociometric Questionnaires

pdf-format:
Document 1.pdf (367 KB)


Abstract

In the paper we design a protocol for sociometric questionnaires, which serves the privacy of responders. We propose a representation of a sociogram by a weighted digraph and interpret individual and collective phenomena of sociometry in terms of graph theory. We discuss security requirements for a privacy-aware protocol for sociometric questionnaires. In the scheme we use additively homomorphic public key cryptosystem, which allows single multiplication. We present the threshold version of the public key system and define individual phases of the scheme. The proposed protocol ensures desired security requirements and can compute sociometric indices without revealing private information about choices of responders.
