  • FIG. 1 is a diagram of a system capable of enabling seamless access to content across multiple devices in common with a single user, according to one embodiment.
  • the system 100 is configured to allow a user of multiple devices lOla-lOln to readily permit the sharing of content based on submission of a request.
  • the request may specify one or more search criteria for supporting the lookup of content at, or available to, the one or more UDs lOla-lOln.
  • Content of various types, sizes and other properties, including audio, video, documents and the like, may be referenced for access by the requesting user device via a shared indexing service 103.
  • a user may employ a mobile device, a desktop computer, a laptop computer, a work related computing device, etc.
  • Each of these devices may feature various applications such as word processors, multimedia players, photo editors, content management utilities, web browsers and various other tools for manipulating, generating or accessing content.
  • a user can choose to access or invoke content of interest, such as photo or documents, by way of any of their devices as long as they have access to the corresponding data source.
  • the data source may include internal memory, an external storage device (e.g., an external hard drive) or a virtual data store accessed via a network connection.
  • One approach is to e-mail the content, such as a document, to themselves as an attachment (e.g., via a mobile email client) and subsequently open the attachment via the second device.
  • the user can proceed to edit the document accordingly, the edited version representing a different version (number and/or date) than the original.
  • the user may store a copy of the original document to a portable/external storage device, couple the storage to the secondary device, then uploads the content accordingly.
  • these approaches are tedious to execute and make it difficult for the user to manage the various representations or versions of the document.
  • the user winds up having multiple different representations of the document stored at different locations.
  • Another approach available to the user is to employ the use of a network data store.
  • the user can access the actual content via any of their devices directly from the data store based on one or more access credentials.
  • this approach does not always make the content easily sharable across devices as the entire content must be placed on the data store; resulting in unnecessary data copying and synchronization.
  • an index to the content on a device may be used for referencing a portion of the content rather than the content in its entirety.
  • the data is indexed and kept on the device for fast retrieval (lookup) of content.
  • not all content is indexed in an efficient manner by the different devices available to the user— i.e., due to different operating system requirements, data compression techniques, etc. This compromises the ability of the user to seamlessly access and/or share content with multiple or devices while maintaining version control and criteria based lookup.
  • a system 100 of FIG. 1 introduces the capability to generate a shared index for referencing the locations of one or more documents associated with one or more user devices.
  • a shared indexing service 103 is configured to interact with the various user devices (UDs) lOla-lOln (e.g., devices belonging to at least one common user), the interactions including: (1) periodically receiving an index from each UD lOla-lOln, the user device including data for indicating at least the device and/or source of the data, a name or identifier of the data, and a version number; (2) generating a shared index 1 12 for representing a compilation of the indices provided by each of the devices in common with a user; (3) maintaining the shared index at a private cloud for on demand reference by a requesting user to facilitate multi-device access.
  • indices for individual devices are maintained at the respective devices 101 while a shared index 112 related to all of the devices is synchronized with each index for access by any individual device 101
  • An index may include, for example, a data structure comprising various key data fields for enabling quick efficient data retrieval operations of a subset of data (e.g., a content database).
  • the index is used to quickly reference the location of data records as maintained at the device or via a location accessible by the device. It is noted that the index is typically a link to the location of the data records and therefore, does not return the content directly.
  • various other index and database retrieval implementations may be employed to meet differing data access requirements.
  • the shared indexing service 103 may employ any indexing techniques and data retrieval mechanisms.
  • the shared indexing service 103 is also configured to present a user interface for enabling the lookup of content at one or more devices based on specified search criteria.
  • the search criteria may include, for example, a file name, a file type, a file size, a date, a version number (and/or date), a keyword, etc. Entry of the search criteria facilitates index processing of the shared indexing service 103 for facilitating the lookup of content at respective locations available to the different UDs.
  • Data sources of the respective UDs lOla-lOln may include, for example, an internal content database 107a-107n of the devices, an external data storage device 111a as coupled to a given UD 101 , a virtual data store 11 In or service 109 available for access via a UD 101, or a combination thereof.
  • the exemplary embodiments herein pertains to both external, internal and virtual (network based) data stores for maintaining content.
  • the shared indexing service 103 may facilitate execution of various security, access and permission settings for supporting device connectivity to various sources.
  • the shared indexing service 103 responds to requests by returning (to the user interface) a link such as a uniform resource identifier (URI).
  • URI uniform resource identifier
  • the link points to the device on which the content subject to the search is available.
  • version information pertaining to the content is also returned as part of the result set for enabling the user to distinguish between multiple different versions of content meeting the search criteria.
  • search criteria may be entered at various fields of the user interface for restricting the search for content to audio files of file type Waveform Audio File Format (WAV) and file name "Live Your Life” (the title of a particular song).
  • WAV Waveform Audio File Format
  • the shared indexing service 103 processes this request to determine at least one location of content items at the one or more devices 101 conforming to the entered search criteria. Processing includes accessing of the shared index 1 12 as stored to the cloud or other data store to perform the cross-referencing of all available content.
  • a list of the devices and/or data stores associated with these devices 101 having access to the song is returned along with version information.
  • the user can then decide from which device lOla-lOln and/or source 11 la- 11 In to retrieve the content and present it to the user. More regarding the user interface as rendered by the shared indexing service 103 for supporting content location lookup is presented more fully with respect to FIGs. 6A and 6B.
  • the data is indexed and stored on the device as well as shared on the cloud 109.
  • the user is able to perform a quick lookup of local data maintained at the device and off-line, as well as more be provided more detailed results from other devices associated with the user.
  • only the indices of respective devices and/or the shared index 112 is provided to requesting users as opposed to the content itself, thus ensuring the data is accessible to only trusted people/devices.
  • the actual content remains at their respective locations (e.g.., 107a-107n, l l la-l l ln, 109) under the control of the respective user devices lOla-lOln.
  • the shared indexing service 103 may therefore permit other users to which the UDs lOla-lOln do not belong— e.g., on a permissions basis— to retrieve the index results (links) but not the content directly.
  • Storage of the shared index to a cloud or other service 109 facilitates a means of privatized access and selective sharing.
  • the shared indexing service 103 may also be configured by a user to enable a periodic or condition based synchronization of respective indices at the different devices 101a- 101 n.
  • the synchronization is performed to ensure persistent updating of the shared index 1 12 as related to a given user relative to those indices maintained by individual devices 101a- 101 ⁇ of the user.
  • the synchronization may include, for example, a retrieval of an index at a given device, an updating of a specific storage location of specific content, an updating of a version number, etc. It is noted that the synchronization settings may be performed periodically or at each instance of a determined change of the content.
  • settings for affecting operation of the shared indexing service 103 may be established, for example, as part of a registration process by the user with a provider of the service 103.
  • the settings may also specify the means of data sharing between the requesting user device (client) and determined source via WiFi, Bluetooth, Internet Protocol, peer-to-peer communication, file sharing, device-to-device sensing (e.g., device overlapping or proximity detection), etc.
  • the system 100 comprises user devices (UDs) 101 having connectivity to the shared indexing service 103 via a communication network 105.
  • Each UD 101 includes an indexer 108 for generating an index related to content stored at or available to each device 101.
  • the indexer may also associate metadata regarding a particular document with the index, such as to support index generation.
  • the indexer 108 generates indices according to known data structure generation protocols and algorithms.
  • the indexer 108 exchanges indices created for a specific device with the shared indexing service 103 on demand or on a periodic basis. It is noted that in certain implementations, the indexer 108 may be implemented as a module for execution by the shared indexing service. Under this approach, indices are created for respective devices by the service 103 then subsequently used to generate the shared index 112.
  • the communication network 105 of system 100 includes one or more networks such as a data network, a wireless network, a telephony network, or any combination thereof.
  • the data network may be any local area network (LAN), metropolitan area network (MAN), wide area network (WAN), a public data network (e.g., the Internet), short range wireless network, or any other suitable packet-switched network, such as a commercially owned, proprietary packet-switched network, e.g., a proprietary cable or fiber-optic network, and the like, or any combination thereof.
