Is there a better way of interacting with digital forensic data from a user interface and user experience standpoint?

Synopsis
The NPCC (2020, p.5) states that: “Digital forensic (DF) science - examining digital evidence to support investigations and prosecutions - was once niche but is now very much mainstream.
Over 90% of all crime is recognised as having a digital element, and society’s accelerating use of technology means the critical role DF science plays will only grow”. They identify three core challenges:
- the sheer volume of data and devices leading to backlogs and delays in investigations;
- the complexity of digital examinations including the variety of devices available, use of encryption, the number of data formats used, and the increasing use of cloud storage;
and - the need to maintain the legitimacy of the police in the digital landscape given 1 and 2 and law enforcement’s need to work in new ways to deal with these issues. (ibid.)
Given the volume of data and complexity of the examinations digital forensic (DF) practitioners work with regularly, this research interviewed 12 DF practitioners in an attempt to understand how the user interface of DF tools may exacerbate these issues, and what their suggestions may be to mitigate these. This work explores the responses, provides and initial analysis, and provides suggestions for how these findings may feed into the next generation of DF tools.
