Functions and Characteristics of e-timing VISUAL TS Verifier for Adobe Reader

  • TS Verification

    It provides a function of verifying TS of PDF digital documents. For TS verification, it verifies the contents for authenticity, which shows the document has not been modified or forged, and its existence (Time-check) which proves the document existed at the time of TS issue.

    It shows information of TS issued on the PDF documents in detail.

  • Technology applied to Prevent Any Modification of the Image

    If the image of TS is falsely modified, it can cause the user in confusion. Therefore, e-timing VISUAL TS for Acrobat houses the image of the stamp in the Dynamic Link Library (DLL) file. Also, to prevent any third party trying to modify the image, the DLL is secured to be opened upon verification of the information on DLL hash.
  • Quick Identification of Forgery

    When a PDF document with a TS issued is opened, the stamp shows it’s been modified or forged after a verification process.
  • Verification Tool Using a Plug-in

    No other viewers need to be installed or required to verify the TS on the PDF documents, apart from a plug-in for Adobe Reader.
