Recent studies show that the installation of an EHR (Electronic Health Record) could help in lowering expense while improving the treatment quality at the same time. Apart from this, such systems could also pose the threat of a privacy invasion, because patients' sensitive medical datasets are stored within an EHR.

UBT-i is a paper based testing approach (i.e. a desk test without the need for executable software) applicable to design specifications. We present an initial empirical study on defect detection effectiveness and efficiency with respect to several defect severity classes and defect locations (code or design).

    abstract = {Today, the health care sector is driven by the need to reduce costs while simultaneously increasing the service quality for patients. One major aspect to reach this goal is the implementation of an EHR (Electronic Health Record) system which also supports the execution of medical standard processes. Nevertheless, these nation-wide medical storages are a promising goal for attackers. Thus, people are naturally concerned about their privacy. These concerns and the lack of existing approaches to provide a sufficient level of security raise the need for a system that guarantees data privacy and keeps the access to health data under strict control of the patient. In this thesis we discuss our approach PIPE (Pseudonymization of Information for Privacy in e-Health), which differs from existing approaches in its ability to securely integrate primary and secondary usage of health data. First of all, we elaborate on existing methods, principles and techniques in the fields of security and privacy. Afterwards, we work out necessary cornerstones of secure EHR systems. Finally, we show how PIPE provides solutions to shortcomings of existing approaches. PIPE may be used as a basis for implementing secure EHR architectures or as an extension to existing systems.},

    abstract = {Project managers recognize that difficult-to-use processes in software development hamper their teams in fulfilling the needed tasks within the planned time. Often the resulting output does not meet the customers needs. On the other hand the business requirements of customers change rapidly and all involved stake-holders should respond by adapting the project goals. Thus they are looking for processes which are more light-weight so they are able to react in shorter time for changed needs. Furthermore project managers want to produce high-quality software with the smallest possible effort to obtain the most profit. In this thesis we introduce a package of verification and validation (V&V) techniques in combination with agile processes and show how they work and which problems could be solved by them. We focus on different methods for defect findings relating on different artifacts in different phases of software development. We introduce a technique that is called Usage-based Implementing (UBI) which is based on PairProgramming. Furthermore we replicate the method Usage-based Testing (UBT) which is conducted as desk-testing (UBT-i). Usage-based Reading (UBR) is a well known technique that we use to set Usage-based Testing and Usage-based Implementing in relation which each other. The results of our pilot study show that a combination of UBI and UBT-i or UBR in an agile process, which we introduce as the Agile Inspection and Implementation Process (AΠP), is a good approach to produce reliable software and to support project teams with errorless artifacts so costs do not exceed expectation.},
