On the 20th and 21st of April 2015, nine representatives of Dutch investigative agencies presented their feedback on the concepts of the‘’Digital Evidence Dashboard’’, a project funded by the HSD Development Fund. This took place at the TNO usability lab in Soesterberg. The project members of TNO guided the participants through the concepts, supported by the project members of Tracks Inspector and In-pact. The concepts had been formulated earlier by TNO and In-pact by interviewing investigators and digital forensics experts.
About the DED Project
The ‘’Digital Evidence Dashboard (DED)’’ project started at the beginning of this year and is made possible by the HSD Development fund from the municipality of The Hague. DED is working towards a new way to investigate the data of captivated digital media: a supporting digital dashboard has to make it possible that a broader group of detectives can investigate within captivated digital data. The aim is to avoid the overcharging of digital experts (not being able to fulfil the information need of detectives).
- DED-case overview: Workflow support for investigations in digital evidence based on working hypothesis
- Search assistance: Providing support with searching through digital evidence. Various search methods are offered including automated analysis.
- Displaying search results: Visualisation of results with drill down options for slicing and dicing through the evidence.
- Linking to working hypotheses: Easy bookmarking of relevant results and putting these in the context of the investigation (invalidating or validating the hypotheses)
- Digital expertise: Make suggestions to users based on digital expert knowledge, present alternative search options and facilitate the articulation of questions to digital experts.
Participants of the PoC have ranked these five concepts based on their value for different aspects of the investigation: efficiency (investigate and collaborate faster and easier), effectivity (usefulness of the output) and usability (how easy is can it be used by a non-technical investigator).
The feedback of the participants will be used to prioritize features when implementing a working prototype in Tracks Inspector. In September this prototype will be validated in a second PoC.
