Ensuring evidence integrity
In a number of jurisdictions, particularly those with human rights legislation which interprets all investigations as a potential breach, the presentation of evidence should not come with challenges to its source or legitimacy; the security, confidentiality, continuity and monitoring under which it has been held; or freedom from interference, tampering or alteration. This – evidence integrity – may be challenged as inadmissible if the defense can argue that it would be unsafe to rely on that evidence due to a breach of any of the above. This can be particularly true of computer hardware and data.
