Digital Verifier Overview
.JPG images and .AVI video files that are exported from the Digital Video Recorder are automatically embedded with a digital signature. Digital Signatures are a way to verify the authenticity of the images to ensure that they have not been tampered with or edited in any way. Included on the Software Installation DVD, supplied with the DVR, is the Digital Signature Verification program. This program can be installed on any computer and loads an image in question.
Using the Digital Verifier
1.Open the Digital Verification program by selecting Start > Programs > HRDP > Digital Verifier > Digital Signature Verifier.
2.Click the Browse button to load the .JPG image.
3.Enter the Site Code of the DVR that the image was originally extracted from. (The Site Code is specified in the System Configuration Menu)
4.Click Verify to continue or Close to close the window without verifying.
If the image has not been tampered with, a blue square will appear around the image with the message “Original image file.”
If the image has been tampered with, a red square will appear around the image with the message “Entire image changed or wrong SITE CODE.”
