Abstract
The invention relates to a method of masking data making up a user profile associated with a node of the network, a user profile consisting of a sub-set of elements present from among a set of possible elements. The masking method includes a step for obtaining an initial data structure including a pre-determined number of binary elements, a so-called binary element being able to have a value from two possible values, the initial data structure being representative of the elements present in the user profile, and, for at least one portion of said binary elements, a step for applying a probabilistic inversion operation of the value of said binary element, depending on a probability value calculated from a pre-determined confidentiality parameter, giving the possibility of obtaining a masked data structure representative of the elements present in the user profile.
