Pirate file-sharing goes 3D
A sharing website known for providing free copyrighted materials.
Music, Film and e-commerce
Books, the website provides \"physical objects\"-digital objects present in physical form due to 3D printers.
At the moment, this printer is an area for enthusiasts and can spit out small plastic trinkets, but technological improvements mean that more complex materials and shapes will soon become possible.
Could the Pirate Bay move open the door for a new wave of piracy because people use 3D scanners to scan objects and share them online?
The improvement of 3D printing technology means that complex shapes should soon become possible. This outlook seems unlikely, but keep in mind that before free music like Napster stimulates demand for the iPod
So maybe the file
Sharing can also do this for 3D printers, bringing them into people\'s homes.
The music industry\'s response to illegal documents
Share with digital rights management (DRM)
Technology that prevents songs from playing on unauthorized devices.
Can companies that sell physical products do the same?
One option is to place a mark on an object that the 3D scanner can detect, which will prevent it from running.
Markus Kuhn, a 2002 computer scientist at the University of Cambridge, found that the technology had been used to prevent paper money from being copied. But he said it wouldn\'t work for a 3D scanner because pirates can simply cover the mark with tape.
He suggested borrowing an alternative from music DRM.
Some companies watermark their audio files by encoding copyright information at frequencies outside the range of human hearing, which are often discarded by compression algorithms.
The equivalent in a physical object is the mechanical tolerance used in manufacturing-for example, one side of the object may be specified as 300 ± 1mm, said Cohn.
The marking algorithm can etching a tiny pattern in the unused part that the scanner will detect.
Tony Rhodes, who works in Oregon.
Digimarc, a digital watermark-based company, said that without changing the printed object, valid 3D files can be marked by subtly changing the 3D design.
This will make the 3D printer distinguish between the manufacturer files that contain the changes and the ones made by scanning objects that do not contain the changes.
Perhaps such technology is irrelevant.

Based on intellectual property (IP)
Public knowledge of the advocacy group says that while text, music and video are automatically copyrighted, \"the vast majority of physical objects are not protected by any form of intellectual property rights \".
Copying an invention protected by a patent is illegal, and copying a trademark mark is also illegal, but it is not illegal to measure a table and build a replica.
If 3D printing becomes more and more common, panic-stricken companies may push for stronger IP laws, but it will be a mistake, Mr Winberg said.
He advises companies to learn from mistakes in the media industry and embrace the new opportunities it offers, perhaps by encouraging legitimate downloads of target files.
\"If everyone can use a 3D printer, I can go online, pick the object I want, customize it and print it out,\" he said . \".
\"This is an incredible opportunity for the company.
They don\'t want to miss the ship any more.
