•Privacy preserved dataset: Creating a parallel universe, which hides everyone’s real life!
•A perturbed Gaussian Copula approach to generate data
–From the original dataset, we extract the PDF/CDF for each attribute 𝒊
–From the original dataset, we analyse the correlation matrix for all pairs of attributes (denoted by 𝑹)
–Then, we perturb the above statistics satisfying differential privacy and generate a privacy preserved dataset
