2Single party provides input data?
It is important to know whether a single party provides the original data from which synthetic data will be created.
No

Privacy-Preserving version of the technique used (see the start of the tree) & Differential Privacy
If there are multiple data providing parties, the data synthesizing algorithm will be applied on them combined, thus there may be a need for applying it in a privacy-preserving way. Thus, the tree should be traversed depending on the type of data synthesizing algorithm used (e.g. if Neural Networks are used, one should traverse the /Machine Learning/Model Training subtree). Differential Privacy should be also used as in 5.1.
