Don't pirate.

couldn't audio watermarking be circumvented by converting it to analog then re-recording it to digital?

Sounds like a waste of time and money to prevent pirating. Obviously it would be simple to strip the audio watermark from the audio file thus rendering it easy to copy.

no, did you read OPs post? "The technique used by MusicTrace embeds the watermark so robustly that the watermarks are still detectable by a computer even after analog conversion."

I read OP's Watermarking link - It's a good idea - but I don't think it'll be difficult to defeat. The article reads more like an infomercial than a technical review.

Interesting idea. I have no idea if this would work though.

Resampling the original will remove any watermark from the audio, ie: 16bit @ 44.1Khz original,
resample to 24bit @ 48Khz = No audio watermark.

How can one be sure that there is no trace of it left?

it wont actually stop pirating will it?

every single one of you in some way or other is guilty of pirating:

how many of you copy tracks to your personal player?
that is pirating.

how many of you sell your unwated music/dvds/games to a second-hand shop?

That too is pirating, because when that item is bought, there is no money sent on to the copyright holder.

Jeez, the RIAA has you trained to be their monkey.

ad hominem attacks are pointless.
Explain.

This isn't simply altering the tiemcode like something like SCMS system from the CD Audio days
[link to en.wikipedia.org]

Nor is it just adding metadata to the container.

This is actually changing the structure of the sine wave slightly so as to make it sonically "different". The software can then detect this different audio and determine where it originated from.

Something similar was done to pre-screen videos of movies. Where the movie industry would give copies of movies to movie reviewers before the movie was released. Well it turned out these people were a big source of the torrent copies. So they started giving each reviewer a slightly different copy that would have little visual queues throughout the movie. They were undetectable to most people. The software could then use the various patterns to create a "serial number" of that particular video and thus they could tell which movie reviewer released it to torrents.

The thing about getting busted for piracy is that people get busted for the way in which they acquire it, not the actual media itself. So if yo are willing to spend a little bit of money there are ways to legitametly acquire media, and then copy it for yourself.

Stuff like Netflix, Redbox & Spotify. You just have to be willing to pay a little bit of money, like a compromise. Its the idiots that download stuff non-chalantly from the internet that get caught. Because you have no idea who your downloading from or who's listening.

I guess we are all just a bunch of fucking pirates then....

Watermarking audio isn't going to stop pirating. Banning guns isn't going to stop violence. Going to war isn't going to create peace.....

Anyone see a pattern emerging?

It depends on the terms set by the inventor/creator of the product when it's sold.
Car makers don't get money when a used car is sold.

That is first sale doctorine and it is mine. I bought the item, I do not agree to any kind of a contract upon buying a physical movie or DVD....do you sign anything at the register???

A song or movie or book is no more "intellectual property" then a car or a hammer. They all took someones time and thought to create. I can't clone a Honda Civic and sell it as my own.

agreed.
and that was my point. governments are saying piracy is illegal cos money isnt going to the copyight holder, sounds fair.

but if i buy a second hand copy, from a shop selling such items, then money still isnt going to the copyright holder.

so, what is the difference between piracy and buying second hand.

and, if you read the copyright notice on music/dvds/games etc, it says in HUGE writting it is illegal to sell, hire or lend this copy.

old tech.

what is old tech?

Maybe if I believed, for instance that the actual artist of a song would be the only person to benefit from these copyright laws I would care more about this, but until then, I have no sympathy whatsoever for people crying about copyrighted material being pirated.

What I am wondering is that if a law suit is brought against you can you claim that you pirated this SPECIFIC version of the song, as they are claiming, and you did not pirate the normal retail version.

Thus the actual "damages" they can claim against you would be severly limited. Since the version you took was probably never actually for sale and was purposefully put on torrent sites to capture people.

On the outside package or the disc itself. Because once you open it you cannot return it, so thus how are you able to agree to such terms?

^^This^^

agreed.

i care little for the copyright laws.

No it is not. If I fashioned music boxes and someone sold theirs I didn't lose anything, if someone sold their cd same thing. I licensed that entity when I took payment for the entity (cd). As for the musicians they get very little. Sony and other music industry ilk ride the backs of the musicians. Sony wants more and more. Remember whom you serve when you advance such arguments.

actually, if you care to watch the start of a dvd you will see it.
i am looking at the DISC of Assassins creed ii and it says on the disc:

RESALE AND RENTAL ARE PROHIBITED unless authorised by scree

it says this in print above the title.

back at ya

If serial codes didn't work for software, there is no reason to believe that this even less secure method will not be pwned within days.

Any type of security that can be thought up will be breached by others that understand the technology.
