    摘要: A DRM scheme that may be optionally invoked by the owner. With the DRM protection turned on, the media is encrypted before it is distributed in a P2P network, and is decrypted prior to its use (play back). The peers may still efficiently distribute and serve without authorization from the owner. Nevertheless, when the media is used (played back), the client node must seek proper authorization from the owner. The invention further provides a hierarchical DRM scheme wherein each packet of the media is associated with a different protection level. In the hierarchical DRM scheme of the invention there is usually an order of the protection level. As a result, in one embodiment of the invention, the decryption key of a lower protection layer is the hash of the decryption key at the higher protection level. That way, a user granted access to the high protection layer may simply hold a single license of that layer, and obtain decryption keys of that layer and below. The invention further provides for a process for managing digital rights to a scalable media file wherein a different encryption/decryption key is used to encrypt each truncatable media packet with a base layer without requiring additional storage space to store the key.

    摘要翻译: 可以由所有者可选地调用的DRM方案。 DRM保护启用后,媒体在分发到P2P网络之前进行加密,并在使用前进行解密(播放)。 同行可能仍然有效地分配和服务,未经业主授权。 然而,当使用(播放)媒体时,客户机节点必须向所有者寻求适当的授权。 本发明还提供了分层DRM方案,其中媒体的每个分组与不同的保护级别相关联。 在本发明的分层DRM方案中,通常具有保护级别的顺序。 结果,在本发明的一个实施例中,较低保护层的解密密钥是较高保护级别的解密密钥的散列。 这样一来,授权访问高保护层的用户可以简单地保持该层的单一许可,并且获得该层及其以下的解密密钥。 本发明还提供了一种用于管理可扩展媒体文件的数字权利的过程,其中使用不同的加密/解密密钥来加密具有基本层的每个可截断媒体分组,而不需要额外的存储空间来存储密钥。

    摘要: A modular magnetic storage system including a container attachable to a surface, the container including a vessel having a top end, a bottom end, a wall and a magnet housing, the bottom end being positioned opposite to the top end, the wall extending between the bottom end and the top end, the wall and the bottom end defining a cavity, the top end defining an opening in the vessel, and the magnet housing defining a recess; a magnet disposed within the recess; and a resilient cover positioned over the magnet housing, the resilient cover providing a coefficient of friction between the resilient cover and the surface to maintain a position of the vessel on the surface.
