Patent number: 10509891Abstract: In one embodiment, an instruction is received at a blockchain server from a first digital rights management (DRM) client, the instruction including an instruction to transfer a DRM license to an encrypted content item to a second DRM client. A block to be recorded in a blockchain, is created, the block including a content item ID of said encrypted content item, one of a device ID of a device including the second DRM client or a user ID of a user of the second DRM client, DRM license information for said DRM license, and a DRM decryption key for decrypting said encrypted content item.

Patent number: 7995603Abstract: A system and a method for secure distribution of digital media content through a packet-based network such as the Internet. The security of the present invention does not require one-to-one key exchange, but rather enables keys, and/or information required in order to build the key, to be broadcast through the packet-based network. The digital media content is then also preferably broadcast, but cannot be accessed without the proper key. However, preferably only authorized end-user devices are able to access the digital media content, by receiving and/or being able to access the proper key. Thus, the present invention is useful for other types of networks in which digital media content is more easily broadcast rather than unicast, in addition to packet-based networks.Type: GrantFiled: May 22, 2001Date of Patent: August 9, 2011Assignee: NDS LimitedInventors: Dan Revital, Steve Epstein, Yossi Tsuria, Arnold Zucker, Steven Simkin

Patent number: 7920702Abstract: A system and a method for providing variable security mechanisms for securing digital content, in which a single security mechanism is not used for all content. Instead, at least one characteristic or feature of the security mechanism is varied between units, instances or categories of content. Therefore, even if unauthorized access is gained to a single unit of content, the overall integrity and security of the system for content distribution is not compromised. Preferably, security is provided though a general mechanism, which is then varied in order to provide variable, dissimilar security schemes for different types of content. By “type of content”, it is meant any of a single unit of content, a single instance of content or a single category of content. For example, for a category of content, the content may be characterized according to the identity of the content itself, such as the title of a movie for example, and/or according to the owner of a particular copy of the content.Type: GrantFiled: February 19, 2009Date of Patent: April 5, 2011Assignee: NDS LimitedInventors: Chaim Shen-Orr, Eliphaz Hibshoosh, Gyora Benedek, Hillel Solow, Yaacov Belenky, Yossi Tsuria, Zvi Shkedy
