Abstract: The embodiments provide for binding files to an external drive, a secured external drive, or portable data locker. The files are bound in order to help restrict or to prevent access and modification by certain computers or users. Computers or users that are authorized or within the authorized domain are permitted full access. The files stored on the external drive may be bound in various ways. The files may be encapsulated in a wrapper that restricts the use and access to these files. The bound files may require execution of a specific application, plug-in, or extension. A computer may thus be required to execute program code that limits the use of the secured files. In one embodiment, the external drive provides the required program code to the computer. In other embodiments, the required program code may be downloaded from a network or provided by an external authority.

Abstract: The present invention relates to digital rights management (DRM) for content that downloaded and saved to a storage device. The storage may be a disk drive, or network attached storage. In addition, the storage device performs cryptographic operations and provides a root of trust. The DRM employs a binding key, a content key, and an access key. The binding key binds the content to a specific storage and is based on a key that is concealed on the storage. The binding key is not stored on the storage device with the content. The content key is a key that has been assigned to the content. The access key is determined based on a cryptographic combination of the content key and the binding key. In one embodiment, the content is provisioned based on the access key and stored in encrypted form in the storage device.

Abstract: The present invention relates to accessing content stored on a storage device and protecting the content with a digital rights management (DRM) scheme. The storage device may be a disk drive, or network attached storage. The storage device can perform cryptographic operations and provide a hardware root of trust. The DRM employs a binding key, a content key, and an access key. The binding key binds the content to the storage device and is based on a key concealed on the storage device. The binding key itself is not stored anywhere on the storage device. The content key is a key assigned to the content. The access key is determined based on a cryptographic combination of the content key and binding key. In one embodiment, the content is encrypted based on the access key and stored in encrypted form in the storage device.
