Yao's Millionaire Problem

Yao's Millionaire Problem is a privacy-preserving protocol where two individuals, each with their own private wealth amount, want to determine who is richer without revealing their actual net worths. Using secure computation techniques, they can compare their numbers securely, ensuring that neither learns the other's exact value, only the comparison result. This allows sharing necessary information while maintaining confidentiality, and it has important applications in secure data analysis and privacy-preserving computations in various fields.
