Creating and using accurate profiles of users for electoral campaigning and political advertising represent a high risk to the right to privacy and personal data protection. By applying sophisticated data-mining techniques, voters’ personal data are collected and processed for electoral purposes usually without their consent and in the absence of legal entitlement. Furthermore, the use of personalised ads and messages, while the target users do not detect personalisation, may, intentionally or not, manipulate the voter’s view. Thus, there is a need for further regulating and for a limitation of the creation and use of individualised profiles for electoral purposes.
