Verifying attachments

ImageMaster supports the verification of attached files based on various mechanisms like a hash value comparison, a digital signature involving an electronic timestamp or even based on evidence records. A corresponding report can be created and downloaded from the WorkplaceClient. If the stamping functionality is active, where an overlay can appear, for example in the document preview, the verification is still based on the original document that is stored in the archive, which does not contain this overlay.

To display the verification status

  • Select the function Verify Attachments expanding the menu Vertical three dots icon from the attachment preview.

    The Verification Overview dialog is displayed:

    Verification overview report with the status verified on the green background and options: summary report, detailed report, and close.
