A method of distributing media content and associated media information as a media package in a file format embodied as a data structure. A method of presenting media content such as Audio or Video including segmenting the media content into sections and storing data and information about the sections as part of media information with the media content in a media package. The presentation program uses information about the users preferences/profile and location and compares it to section information in order to present certain sections and skip others during the presentation. During presentation, informative messages are inserted between sections if sponsor supported presentation is chosen. Any part of the media content or media information can be embedded in the file or can be linked to from the file and can also be determined using a script or program.

A method to protect the financial rights of tiered media content providers including the original media content owner and media enhancers who add enhancements as additional media information or additional media content to be presented in conjunction with the media content when chosen by user.

A method to distribute and monetize media content by associating media content with a cost stored in associated media information within a media package. The user can elect to pay all of the cost, a portion of the cost, or none of the cost. When the user does not pay all of the cost, informative messages paid for by sponsors can be presented as part of the presentation of media content.

The invention relates to embedding auxiliary data in the form of a multibit payload in a host signal, and encrypting the associated detection key. Moreover, the invention relates to extracting the auxiliary data in the form of the multibit payload from a data signal. Auxiliary data is embedded in a host signal by the following steps. First a reference watermark is provided, subsequently an encrypted detection key associated only with the reference watermark is generated. The encrypted detection key may be a scrambled version of the watermark. In a further step, the multibit watermark is generated and a multibit payload is encoded into the reference watermark. Finally, the multibit watermark is embedded into the host signal.

A central packaging data (CPD) management system provides an online environment in which customers manage packaging data for their respective products. The CPD management system securely distributes the packaging data to manufacturing sites or other output locations, and allows the customers to control the printed output material applied to their packaging and manufactured products. The CPD management system includes a set of packaging templates having data fields selected from a set of data field types, and an artwork importation module that processes a graphic file to identify elements of a packaging layout. The artwork importer generates metadata that associates each of the elements with a respective one of the data field types of the packaging templates. A record manager presents an interface by which a user forms packaging records based on the metadata. An output manager communicates the packaging record to an output location to control printing of packaging material.

The invention includes a method and apparatus for authenticating a wireless node requesting to join a network. A method includes receiving an authentication request from the wireless node, negotiating at least one authentication parameter with the wireless node, deriving a first encryption key using the at least one authentication parameter, encrypting a second encryption key using the first encryption key, and propagating the encrypted second encryption key toward the wireless node, wherein the wireless node independently derives the first encryption key for use in decrypting the encrypted second encryption key received from the authentication server node. The wireless node decrypts the encrypted second encryption key and stores the second encryption key for use to securely communicate with other wireless nodes of the network. In one embodiment, the present invention may be implemented using a modified version of the EAP-TLS protocol, in which rather than a Pairwise Master Key (PMK) being sent from the authentication server node to the wireless node, the authentication server node and the wireless node each derive the PMK and the authentication server node securely provides a group encryption key to the wireless node by encrypting the group encryption key using the PMK.

A key or licence management system for the secure online distribution of digitized audio-visual works (“media”) using encryption techniques. Encrypted media is stored on a media server while the encryption keys are stored on a media key server. Users acquire rights from online retailers to obtain from the media key server keys corresponding to the media they wish to play. The key server encrypts keys before releasing them, preferably with the user's public key using a public key encryption algorithm. Keys are stored in volatile memory at the user's client device and thus the user is in receipt of the key just in time to play the media.

There is provided a quantum-key distribution method between a plurality of users or groups. A center prepares a predetermined number of entangled states consisting of qubits equal to the number of the users, and generates quantum states consisting of the qubits belonging to each of the entangled states and corresponding to each of the users. The center transmits each of the quantum states to each of the users after an authentication process. Each of the users receiving the quantum state makes public an axis used to measure each of the qubits constituting the quantum states. The number of users in each group measuring the qubits with a predetermined axis is represented by module 4. If the sum of the module 4 of each group is even, each group collects the qubit measurement results of the users and acquires each group key. Therefore, it is possible to provide a high-security quantum-key distribution method between an unspecified number of users or groups.

The present invention is related to providing, in association with an image, information related to the image capture device used to capture the image. In one embodiment, information related to a first static camera characteristic and camera setting information related to a first captured digitized image is embedded in the first captured digitized image using a watermark. The watermarked information may be used to identify the source or owner of the picture, and/or to aid in the more accurate reproduction of the image.

An encrypted data distributing method includes preparing cipher text which can be decrypted only by a specific trusted device, and performing encryption and decryption processing at a high speed. An encryption key is prepared using an encryption device authentication key unique to an encryption device and a decryption device authentication key unique to a decryption device, and cipher text is prepared by this encryption key. The authentication keys are also sent to the decryption device. In the decryption device, the decryption device authentication key received from the encryption device is compared with the decryption device authentication key prepared by the decryption device to perform decryption processing only when the authentication keys match.

A method and apparatus for providing secured content distribution using a media hub is disclosed. In one embodiment, conditional access encrypted content is received at the media hub. The conditional access encrypted content is decrypted. The content is re-encrypted in accordance with a unique tier associated with the media hub and one or more devices in response to a request from at least one device associated with the unique tier. The re-encrypted content is provided to the at least one device in response to the request from the at least one device associated with the unique tier.
