Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for initiating a backup, backing up encrypted data, and restoring backed up encrypted data. The method for initiating a backup includes sending a backup secret to a backup device having an encrypted file system, receiving from the backup device a backup ticket created based on the backup secret, and storing the backup ticket. The method for backing up encrypted data includes receiving a backup ticket and a backup secret, retrieving an escrow key bag containing protection class keys, decrypting the protection class keys with the backup ticket, generating a backup key bag containing new protection class keys, selecting a set of encrypted files to back up, decrypting the file encryption keys with corresponding decrypted protection class keys, re-encrypting the file encryption keys with new protection class keys, and transferring the selected encrypted files, the backup key bag, and metadata.

Abstract: A method and system for providing multiple ophthalmic and retinal blood measurements is outlined. By extracting multiple digitized wavelength images and quantitative data within a relatively short time period the method allows for compensation of a patient's eye or head movement, generation of ophthalmic clinical records, and determination of data relating to blood measurements, such as oxygen saturation and hemoglobin, in addition to ocular and other disease determinations. The method provides for multiple analysis and measurements within a single sitting of the patient, with a single simple instrument and without adaptations to the instrument during a patient's eye examination. Beneficially the approach allows for low cost, compact, and even portable implementations offering such analysis and determination outside the current ophthalmic centers providing eased access and earlier diagnosis opportunities.

Abstract: A method is disclosed where an e-book lending library is provided. The lending library includes data relating to one of license data relating to a plurality of e-books and a plurality of e-books. A request to borrow a first e-book of the plurality of e-books for a predetermined finite period of time is received at the e-book lending library. A current lending status of the first e-book is determined as one of available for lending and unavailable for lending. When it is determined that the first e-book is unavailable for lending, a second signal is transmitted to the user via the communication network, the second signal comprising an offer to sell to the user the first e-book via the e-book lending library.

Abstract: A method is provided in which time slicing data, including an indication of available time blocks for loaning an e-book from an e-book lending library, are provided to a user in response to the user requesting to borrow an e-book that is not currently available for being loaned. When the user selects an available time block via an electronic device, the e-book lending library provides to an electronic device that is associated with the user, via the communications network, a lending license for the e-book that is valid only during the selected available time block. The e-book lending library enables access to the first e-book via the electronic device, during the selected time block, using the provided lending license.

Abstract: A system and method are provided for streaming resource replication, registration and delivery. A nonlocal streaming resource is replicated in a local network as a local multicast resource. The local multicast source is registered on a resource management server with an entry which identifies the nonlocal resource and contains information for use in locally accessing the local multicast resource. When a local client of the local network requests access to the local multicast resource, the resource management server determines that the local client and the local multicast source are local to each other and provides a response for enabling direct local access by the local client to the local multicast resource.

Abstract: A method comprises using a cellular telephone associated with a first party to transmit, during a first period of time, voice data from the first party to a second party via a cellular wireless telephone network. During the first period of time, a first video camera other than an integrated video camera of the cellular telephone is used to capture video data relating to the first party. The captured video data is transmitted to the second party via a communication network other than the cellular wireless telephone network. Audio content that is based on the voice data and video content that is based on the video data is provided to the second party, the audio content being synchronized with the video content.

Abstract: A method is disclosed where an e-book lending library is provided. The lending library includes data relating a plurality of e-books. A first e-book from the plurality of e-books is loaned to a user for a predetermined finite period of time, which comprises transmitting to an electronic device associated with the user, via a communications network, the first e-book including a lending license therefore. Upon expiration of the predetermined finite period of time, data is received from the electronic device relating to the user's reading history of the first e-book. The user's reading progress through the first e-book is determined automatically based on the data. When it is determined that the user has other than finished reading the first e-book, a signal is transmitted to the electronic device via the communication network, the signal comprising an offer to sell to the user the first e-book via the e-book lending library.

Abstract: A system and method are provided for resource registration and delivery. A local resource is registered on a nonlocal server with an entry which identifies the local resource and contains information for use in locally accessing the local resource. When a local client of a local network local to the local resource requests access to the local resource, the nonlocal server determines that the local client and the local resource are local to each other and provides a response for enabling direct local access by the local client to the local resource.

Abstract: A method is disclosed where an e-book lending library is provided, the e-book lending library comprising a plurality of e-books. An e-book and an e-book lending license that is valid for a predetermined loan period is provided from the e-book lending library to an electronic device associated with a first user, via a communication network disposed therebetween. An indication of a time block during the loan period, and other than including an end of the loan period, is received from the first user via the communication network, during which time block the first user agrees to relinquish the lending license. The first user's access to the e-book is disabled at a start of the time block, and the lending license is assigned to a different user during the time block. At an end of the time block, the first user's access to the e-book is enabled.
