Abstract
The present invention aims to improve data protection against illegal access by a strong differentiation of the security level specific on a type of data so that when the protection on a part of the data is violated, the remaining data are still inaccessible. A method for controlling access, via an open communication network, to user private data, comprising steps of: dividing the user private data into a plurality of categories, each category defining a privacy level of the data, encrypting the user private data of each category with a category key pertaining to the category of the data, attributing to a stakeholder a device configured for accessing to at least one category of user private data, and authorizing the access to the at least one category of user private data for the device of the stakeholder, by providing the stakeholder with the category keys required for decrypting the user private data of the corresponding category.
