business - How can I protect my job from a client publishing it elsewhere?

I am designing a brochure of 1,872 pages for a client. This client is asking me provide him with a copy of the job. I am 100% sure if I provide a copy this job is gone. He will print it elsewhere. This client loves my graphics, but he doesn't want to pay for it. I must definitely provide a copy for him. My questions are:

1. Is there a way to protect the job from him printing it?


2. Is there software I can pass my Corel Draw file through to lock and protect the job, but such that it is still readable?



3. Is there a way I can secure my file so that even when printed it will lose quality or come out blurred?


4. Is there a way I can make it readable, but not printable?

Is there software at all for Corel file security?
