The composition property of differential privacy allows for the combination of multiple differentially private operations while maintaining an overall privacy guarantee. It means that the privacy losses associated with individual operations can be quantified and added together to get the total privacy budget. Composition enables the construction of complex data analysis processes using differentially private components. This property is analogous to building subroutines in programming, where complex tasks are broken down into smaller, manageable parts It allows for sophisticated analyses where the total privacy loss is controlled and kept within acceptable limits, enabling more complex and useful data processing while ensuring privacy protection.
