Watermarking
The TransVu supports the facility to watermark recorded images.
It is also possible within this menu to produce a watermark certificate which can be used as part of the evidence
to prove that the recorded images have not been altered or tampered with. This is achieved with the allocation of
a unique MD5 signature which would change if the image files are altered.
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 TransVu by using file information and generating the unique
signature.

Description
Enter the start time and date for the time period which you wish to allocate a
watermark to the recorded video.
Enter the end time and date for the time period which you wish to allocate a
watermark to the recorded video.
This will identify the Operator or Administrator responsible for generating the
watermark certificate and can be used as part of the audit trail.
This is the step size in bytes used when calculating the watermark, if the step size is
set to 1 then every byte in the in the video partition will be part of the watermark
calculation.
Note: The smaller the step size the more information that is to be processed. The
process time will increase, this is displayed in the status bar.
