Do yourself a favor - don't think about it - just launch it.

There isn't to much you can do to prevent others from copying your work or sharing it with other people.

Just my opinion, but don't let fear paralyze you from releasing your product.

There is nothing you can do to prevent it. Simple, brutal, honest truth. If you don't release your product because of that fear, you won't see a single dollar come out of it.

Don't worry about it... I found one of my products completely ripped off letter by letter selling on e-bay for half the price... You can't prevent it... just do it and don't worry about it...

If anyone rips off my products I just hit the hosting provider and payment processor with a DMCA notice copied to the offender.

Usually the copied product disappears within 24 hours.

In general terms do not worry about it. Launch your product and deal with issues as they arise.

there is nothing you can do about it. even if you have really good security, your product still can be copy.what if your buyer that copy your product and lunch for their own?or spread to others for free?.. there is no solution for this. just release your product, dont even care about this problem..

Register it with the copyright office. Cheap and proves you wrote it, in addition it may allow for the recovery of statutory damages in a lawsuit.

Plan on it. Someone will either copy it, or simply put it out there for free download to anyone that wants it. Just don't concentrate on the jerks the do this because they are not your market. They are freeloaders, losers, and will never put the information to use. If they did buy, they would refund. They are bottom feeders. Ignore them.

Instead put your effort into improving your product, making new versions, increasing sales, etc. You can take steps to minimize theft, but dont' go Moby Dick about it or you'll just be a miserable old goat.

Just do the best you can, like killing the right click in your pdf so they have to type everything out just little things like that.

Good Luck

Nothing personal intended here, but most ebook products are not so fabulously great that there's a rush to steal the contents. With any luck, your product won't be that great either.

You can either spend your time obsessing about what somebody else might do, or you can invest your time planning and carrying out a kickass marketing campaign. Putting your mind on where you want to go gets you there a lot faster than worrying about obstacles that haven't even come up yet.

One strategy you can (and probably should) use is to include bounceback offers in your product so that no matter who sells it, the readers all get directed back to you for all the followup traffic and sales.

As several other posters have suggested, if some bottom feeder does happen to try and feed off you, just have a simple plan in place to deal with it. This lets you stay flexible and proactive and handle weird people without ever breaking stride.

For example, you'll get unreasonable refund requests. Refund 'em and move on.

You might have server downtime. Hey it happens... wait it out or change hosts... move on.

Your site may get hacked and trashed... fix it from the backup you keep and move on.

Unexpected crises may hit your personal life... handle it the best you can and move on.

Fear is a great immobilizer. And if you let it, it'll rob you of much more than any two-bit pissant copyright infringer ever could.

Hope this helps.

From experience...

The worst that could happen is:

You worry so much about getting ripped off that you spend a fortune on products which'll stop you getting ripped off (as much)

...then you decide not to launch at all.

DON'T fall into that trap.

Since you (now) know you're going to be ripped off, PLAN FOR IT!!! Turn the theft into a (viral) advantage. Figure out a way to get a benefit from someone who did NOT pay you for the product somehow.

Some people put affiliate links in their digital product to do that. Others let affiliates sell the product and keep 100% of the sales but set it up with a $7 script that adds the reseller's buyers to the product creator's mailing list so that the list grows large quickly from the efforts of others.

Take that weakness and use it to your advantage, turn it into a strength somehow.

That is a ridiculous comment. That itself doesn't stop anybody.

I will advice you to release it and think of other uses you can put the product to. Do enough marketing you will enjoy the fruit of your labour.
