the simulation of human movements in areas such as sports, orthopedics or
medicine. As part of our investigations, we assess the accuracy of the used
scanner (Vitronic VITUS smart 3D Bodyscanner). Basic sources of error such as
the distance between scan lines, scan holes and geometric distortions are
discussed, and their influence on the body measurements is further explored.
We finally demonstrate the performance and repeatability of our automatic
measurements in xperiments with several test persons and compare the
results with manual reference measurements.

Presently a higher and higher value is attached to data security. Companies
become aware of the importance of protecting their data against illegal thirdparty
access. One area that is often overlooked or underestimated is the one
of the security of backups. They must also be protected from unauthorized
access. One approach to achieve this level of security is to encrypt the
backups. A particularly promising approach in this area is the encryption using
Trusted Computing. Data is tied to a hardware chip of a specific physical
hardware and can only be restored on this very platform on which it was
previously made. Despite the number of backup programs that can be found
on the market, there are none that fulfil this security requirement
satisfactorily. Therefore this thesis describes scenarios that were developed in
order to represent the basic use cases for the procedure of backup. The
backup systems already on the market as well as the use cases are analysed.
Based on the obtained findings, basic requirements for a backup program
that is optimal in terms of trustworthiness are developed. Using these criteria,
a concept for a prototype of an ideal backup program is created. The paper
discusses the problems which arise in the development of such a program
and describes the solutions to overcome these problems. The solutions lead
to the creation of specifications and the choice of technologies in order to
use them for the backup prototype. Furthermore, the prototype is
implemented and this paper describes which tools are used for this
implementation and what operations are performed. The reader should thus
be enabled to understand this program as well as to adjust it to his own
needs. After the implementation of the prototype extensive tests of this
program and the abstract concept of trusted backups are conducted. In order
to do so, abuse cases were developed and applied to the previously created
scenarios.
