Microsoft patent: Blocking “prohibited content” in cloud storage services

a Microsoft patent stipulates to identify unauthorized or unwanted content in online storage services and to prevent that it be shared with others. The protection law published on 4th April 2017 of the US Patent Office was discovered first by TorrentFreak and already applied for in November 2013.

US patent 9.614.850 (PDF) proposes methods “to block banned content and to identify repeat offenders in service-provider-storage systems”. “Many violations” within a certain period the account of the offender to mark then, to enable further action.

fingerprinting techniques are already by service providers like YouTube, Facebook and dropbox used to find unwanted content – in particular copyrighted content, which rights holders have objections to their sharing. Microsoft goes beyond with his patent application, but also and provides involved the discovery that users to enforce graduated measures.

“Objects in a shared memory system can be labelled a for this, that they include forbidden content”, it is awkward in the application. “If incidents of such marking, they are in a store event chronicle associated with the users responsible for these objects. The Chronicle of the event can be processed, repeatedly to identify offenders and to change the access rights for this user.”

the document describes measures to be taken when detected violations. “If however, objects are shared by a user with another user, then forbidden content is excluded from further sharing with another user, while still hits the other user on the remaining objects are possible”, it is about.

even if it is not expressly mentioned in the patent specification, located near, that Microsoft wants to meet the demands of copyright holders so that. The Digital Millennium Copyright Act (DMCA) makes online services in the United States, to prevent the sharing of copyright-protected content. Microsoft wants to but apparently the same, without removing radically all suspicious files.

the removal of files could violate undisputed rights of users in cloud storage services, argues TorrentFreak. When buying an album about the storage is permitted this in their personal cloud. In this case, would be the service provider with a blocked sharing function on the safe side and could continue to leave the file on his server.

of course tougher measures by the respective service providers would be possible for identified users logged infringements which the patent application but does not execute. As so often in published patents remains unclear to what extent the applicant will actually implement the methods.
