Compared to the material world, data traces will to an increasing degree be used for the purpose of personalisation in the e-world. The article examines both the risks for the self-determination of the data subject and the safeguards of data protection law in this world. It is apparent that the requirements of data protection law are frequently not observed. However, the law is able to form the legal basis of necessary personalisations and to protect the data subject if this process is carried out without his/her consent. It is important to distinguish these single processes from the accumulating effects of ubiquitous electronic personalisation. The latter form fundamental problems for democratic societies, and data protection laws do not have the ability to solve these issues. In contrast, there is a strong need for the separation between personalisation and control on a technical level.ControlData ProtectionDatenschutzDatensparsamkeitIdentitätsinfrastrukturenIdentity Infrastructureinformational Separation of Powersinformationelle GewaltenteilungKontrollePersonal DataPersonality ProfilePersonenbezogene DatenPersönlichkeitsprofilRestricted Data ProcessingTechnikgestaltungTechnology DesignText/Journal Article1861-8936
