In this paper we define a proposal for an alternative data dissemination strategy of the Italian Household Expenditure Survey (HES). The proposal moves from partitioning the set of users in different groups homogeneous in terms of needs, type of statistical analyses and access to external information. Such a partition allows the release of different data products that are hierarchical in information content and that may be protected using different data disclosure limitation methods. A new masking procedure that combines Migroaggregation and Data Swapping is proposed to preserve sampling weights.
