Scenarios where composition techniques might not be directly
applicable:
There are scenarios where composition techniques might not be directly
suitable:
1. Non-Additive Noise: If differential privacy mechanisms introduce
non-additive noise (e.g., multiplicative noise), traditional composition
techniques designed for additive noise may not apply directly.
2. Complex Correlations: When correlations between queries are
intricate, it might be challenging to determine how their combined
effects impact privacy. Traditional composition methods might not
capture such complexities.
3. Advanced Mechanisms: For advanced mechanisms like secure multi-party
computation or homomorphic encryption, composition techniques might
require specialized adaptations to account for unique privacy and
computational aspects.
