Details about technology DPP (Digital Personal Property)
According to Ars Technica, the IEEE organization has created a working group to work on the specifications of the DPP (Digital Personal Property) format, which is considered as an alternative to DRM. This is a very unusual technology. It is all built around a paradoxical idea that you may lose your rights to digital property , and this opportunity will be specifically implemented technologically. Simply put, the concept of unpunished theft of rights to view files is introduced.
Encrypted DPP files can be freely copied from the device to the device on the Internet, but they will be distributed in an encrypted form and there is one trick here - you cannot view the file without access to the cryptokey (playkey), which is stored separately from the file and only in a single copy. The key personifies ownership. At the same time, any person who gains access to the content has the opportunity to “steal” it from you, that is, to transfer the cryptokey to your device. Then he can change the rights, for example, prohibit you - the former owner of the file - to view it.
DPP offers to perceive a digital file as a physical object. For example, you can lend your car to a friend or relative, but you will not leave it near the house with the keys in the ignition, otherwise you will simply lose your property. The same will now be with the files. You can do anything with a file — open access to hundreds of people (if you are sure of these people), make archival copies, even sell the file. But you cannot share it with the whole world, because there will definitely be someone who overwrites the access rights.
Thus, record corporations are trying to instill in users a new culture of handling digital content. In their opinion, only the threat of theft can make people appreciate and protect their property.

The idea of ​​realizing ownership of digital content using cryptographic techniques is truly respectful. Still, people with fantasy have not been translated, even in the community of copyright advocates. Such ideas are extremely idealistic, because to implement them in life you need to completely destroy all the "open" file formats and all devices that can play them, and all programs that can record such files that are not protected by a cryptokey. How can you ban all this software and hardware in practice? Of course, nothing.
But the idea is still interesting.
