Hello,

I’m creating a solution where I need to secure the main file, preventing copies to other computers.

First with FM 11, I was using MAC Address and other security steps. But with FM 12, we have available the new function called Get(PersistentID), with purpose of this is to “return a text representing a unique identifier of the computer or device, like 78569d0bd40b898a64e7d08ccdea8220”.

Now my questions:

  1. If I format the computer and reinstall a new or different FM 12 (not the same serial), there will be a different ID?
  2. The Persistent ID how is obtained? Throw hardware (like Mac address) or software (OS serial, FM Serial).

Thanks in advance

Hi Capsprojectos,

 

Sorry this was never answered for you... so I will handle it now.

 

The persistantID is the same as long as a FileMaker Product stays on the Machine.  If someone formats the box, then at that time no FileMaker product will be on the machine, and it will get a NEW  persistantID.

 

I am not sure how FMI generates the ID.   From my perspective it is a blackbox that FMI created that runs...and kicks out a result.  According to the Knowledge base, as long as their is a product on the device (and presumably computer), then the ID stays unchanged.   Deleting all the copies of FileMaker... then reinstalling FileMaker... causes this number to reset to something new.
