.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.
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."
