In our information society with processing of personal data in almost all areas of life, the legally granted right to privacy
is quite hard to preserve. User-controlled identity management systems have been proposed as a means to manage one’s own private
sphere. Still there is no functioning concept how privacy protection can be effectively safeguarded over a long time period
and how self-determination in the field of privacy can be maintained in all stages of life from the womb to the tomb. When
user control and the capability to exercise rights can not yet or no longer be carried out by the data subject herself, the
decisions concerning the processing of personal data may have to be delegated to a delegate. In this text, we elaborate on
delegation of privacy-relevant actions under a lifelong perspective and point out possible legal, technological, and organizational
measures to appropriately take up the arising challenges. For crucial gaps in current concepts we sketch solutions and explain
implications on user-controlled identity management systems. Finally we give recommendations to stakeholders such as data
controllers, application designers and policy makers.

Es wurde untersucht, wann 35 zukünftige Informations- undKommunikationstechniken Realität sein könnten bzw. ob diese überhaupt realisiert sein werden. Analysiert wird außerdem, welche Auswirkungen dadurch zu erwarten sind und welche Hemmnisse einer Realisierung im Weg stehen könnten.
There are many navigation systems for visually impaired people but few can provide dynamic interactions and adaptability to changes. None of these systems work seamlessly both indoors and outdoors. Drishti uses a precise position measurement system, a wireless connection, a wearable computer, and a vocal communication interface to guide blind users and help them travel in familiar and unfamiliar environments independently and safely. Outdoors, it uses DGPS as its location system to keep the user as close as possible to the central line of sidewalks of campus and downtown areas; it provides the user with an optimal route by means of its dynamic routing and rerouting ability. The user can switch the system from an outdoor to an indoor environment with a simple vocal command. An OEM ultrasound positioning system is used to provide precise indoor location measurements. Experiments show an in-door accuracy of 22 cm. The user can get vocal prompts to avoid possible obstacles and step-by-step walking guidance to move about in an indoor environment. This paper describes the Drishti system and focuses on the indoor navigation design and lessons learned in integrating the indoor with the outdoor system.
