Report on options for large file handling

This Deliverable, D3.4 "Report on options for large file handling" (hereinafter 'Deliverable D3.4'), illustrates the scenario where the large-file evidence exchange may take place and discusses some solutions to deal with handling such large files of evidence. The general evidence exchange scenario has been already been discussed in details in previous deliverables, namely in D3.1, D3.2 and D3.3. The present document specifically reflects on the possible options for handling large files during the evidence exchange process. These aspects have been raised numerous times during the technical meetings under EVIDENCE2e-CODEX Work Packages 3 and 41, as well as within internal project meetings, including with the colleagues of the EXEC project, led by the Austrian Ministry of Constitutional Affairs, Reforms, Deregulation and Justice, and the e-Evidence Digital Exchange System, led by the European Commission via DG Justice and Consumers. All proposed solutions consider the following points: 1. The integration is accomplished by common requirements in order to leave each Member State to choose the most suitable configuration/technical solution for their systems; 2. The large file to be exchanged should be under the national Competent Authority guidance/control or, alternatively, it could be directly managed by the national police organisations involved in the case; 3.The encryption strategies to be adopted would be up to each Member State, so every technical solution described in the current deliverable has been proposed as one of the most common/popular manner to tackle the issue.
