How to Configure Watermarking
The Digital Sprite 2 supports the facility to watermark recorded images. It is also
possible to produce a watermark certificate which proves that an image has not
been altered or tampered with; this is achieved with the allocation of a unique
MD5 signature which will change if the image files are changed.
This process can assist with the audit trail process for digital recorded video. The MD5 signature
is a unique signature that is automatically allocated by the Digital Sprite 2 by using file
information and generating the unique signature.
To configure and produce a watermark certificate it is presumed that the Tools option has been
enabled in the Advanced Features menu:
1. Select Tools -> Watermark.
2. Enter the start time and date for the period that is to be reviewed.
3. Enter the finish time and date for the period that is to be reviewed.
4. Select partition information button, the recorded files within the specified time period will be
displayed within the partition information summary.
5. Highlight the files (partition) that you intend to allocate a watermark to.
6. It is possible to view the index information by selecting the get index info button, the video
index information will be displayed.
7. If the Operator that is generating the watermark certificates is to be logged, enter the report
author information, this will be added to the certificate.
8. Enter the step size information; this identifies the ‘skip’ distance between bytes used in the
watermark calculations, default 256 bytes.
