Labview prgroam Intellectual Property Protection

[sam_chan88hk@yahoo.com.hk]

We are building customized test solution for customer. Recently, customer is asking to provide the labview program source code any all vi without password lock for filing purpose.

Just want to know is there any way to prevent a program being copy to other computer? so that the program source is really for filing not for duplication?

Hi Sam,

When your customer gets the full source code for filing then how do you want prevent any code changes afterwards? With open source code there is no protection...
You might try obfuscation instead.

how about an .pdf of the blockdiagram instead of the actual .vi?

If they're asking for the VI without password protection, they're unlikely to be content with the pdf.  If they are, you'd want to hide your logic under subVIs with custom icons that are relatively meaningless to someone else.

Really, if you give someone your unprotected source code there's no way to prevent them from using the source code.  You could get them to sign a legally binding document.  But, that wouldn't stop them as much as it'd give you an avenue to pursue if you ever caught them using it in a way they weren't meant to.

How would you separate your ip from the code that they bought and paid for? Having seen numerous contractors go out of business after short times, the customer is wise to request the source code.

As a side note, I find it funny that you are so concerned about hiding code but you use your email address for every spam bot on the world to pick up.

It's only a yahoo address! That's about as discardable as garbage. 🙂
