WebMaDa Extension Addressing Transparency Request for Data Owners

 The task of this assignment is to develop a user-friendly solution addressing the transparency request under WebMaDa. To reach this goal the following work needs to be done: FIrst, it needs to be analyzed what information is stored in the existing database using MySQL and how stored data is linked together, because for each network ten tables are stored with interrelated information. Second, it needs to be analyzed how to access this database in a secure manner and how data can be extracted and ported to WeMaDa to display it to the data owner. This will include decision taking concerning re-use/new creation of data transport solution and credential checks for data owner. Next, the access and data transfer solution will be designed and implemented combined with a user-friendly GUI integrated in the existing WebMaDa. Important is that envisioned functionality is only available to network owners and not to authorized external viewers. This GUI needs to offer the data owner filtering options to request specified data (e.g., What data did user X access? Who accessed data of sensor X?). The resulting presentation of the data access should also indicate timestamps of the access. Finally, the developed solution will be evaluated concerning workflow, filtering, and performance.
