Steps to Verify Chain of Custody

To verify the chain of custody of a saved video complete the steps below.

Step 1: Navigate to the Saved Video tab on the left side of the console.

Step 2: Find the saved clip and download it.

Step 3: Click on the thumbnail (first picture below) of the clip to open the clip information pane (second picture below) and copy the command next to "Validate."

Step 4: Open the terminal on your computer (if on PC open Powershell) and navigate to your Downloads folder or wherever you downloaded the clip to.

% cd ./path/to/file

Step 5: Run the validate command, as collected in step 3, with the clip file name attached to get the checksum for that clip (For PC: Hash = Checksum). 

Command

% shasum -a 256 Eric\ Test.mp4 (Mac)

> Get-FileHash './Eric Test.mp4' (PC)

Output

Mac
% 844a68d28664b77ddbda092d03d0949f5d6273c29cb2cbf98921f748c4fee712  Eric Test.mp4

PC
> Algorithm       Hash                                                                   Path
  ---------       ----                                                                   ----
  SHA256          844A68D28664B77DDBDA092D03D0949F5D6273C29CB2CBF98921F748C4FEE712       /Users/Downloads/Eric Test.mp4

Step 6: Copy the checksum from the output and replace the below "Sting1" with it. Then, in the clip information pane copy the checksum next to "Checksum" and replace the below "String2" with it.

Mac Command

% [[ "string1" == "string2" ]] && echo "True" || echo "False"

Windows Command

% "String1" -eq "String2"

Step 7: Verify the output of Step 6. If "True" is output then the checksums are the same. If "False" is the output then the checksums are not the same. 

Validate command:

% shasum -a 256 ./path/to/file (Mac)

> Get-FileHash ./path/to/file (PC)
