A data synchronization method for more than three networked devices including at least one client and one server for efficiently synchronizing data among multiple devices supporting a Synchronization Markup Language (SyncML) protocol is provided. The data synchronization method includes determining whether a data item indicated by synchronization information contained in a synchronization request message exists in a change log table of the server, when a server receives the synchronization request message sent by a first client, and updating the change log table by adding the data item indicated by the synchronization information and transmitting a synchronization request message containing a data identifier and the change log of the data item to a second client, if a data item indicated by the synchronization information does not exist, otherwise, ending data synchronization by transmitting a synchronization response message containing status information to the first client.

A collaboration program operates on a computer system for storing, sharing and synchronizing data between different users. Centrally stored content data items are organized by associations into one or more folders, with the folders arranged by associations in a multi-level hierarchical structure. Users have access to all folders and content data items falling within at least one top level folder or “file cabinet” viewable by that user. When a user makes a change/addition to the hierarchical structure, that change/addition is transmitted to a server, which makes the change/addition to the necessary associations and sends messages through a TCP/IP format advising other signed-on users of the change/addition. With each content data item having the capability of being associated into multiple folders and each folder having the capability of being associated into multiple other folders or file cabinets, the computer system operating the collaboration program gives different users simultaneous, synchronized access to the folders and content data items in the hierarchical structure.

Universal synchronization of profiles of audience members targeted for the delivery of content. A unique global identifier may be assigned to and used to manage a profiled audience member. This identifier may also be associated to an authoritative identifier and cookie information used in connection with the collection of profile data. An authoritative identifier may be received in connection with activity, and might not be accompanied by a global identifier. The authoritative identifier may then be used to identify the global identifier, which in turn may be used to identify the cookie related information of record for the profiled audience member. Comparing the cookie related information to previously retained cookie information may be used to determine that the cookie information for a particular, profiled audience member has changed, so that it can be restored.

Systems and methods for providing privacy of file synchronization with sharing functionality are presented. In embodiments, a file synchronization system comprises one or more folders associated with one or more non-shared encryption keys, which may be a managed key shared across an organization, and/or a personal key that is not shared or has limited third-party sharing. The one or more non-shared encryption keys are not known to the data storage service. The file synchronization system may also contain one or more folders associated with a shared encryption key that is shared with the data storage service, and in embodiments, with a set of users of the service. The system may include a mapping correlating folders to encryption type so items in each folder can be handled appropriately.

A multimedia server system includes a disk array subsystem including a plurality of multimedia files, e.g., movies, a media file system manager for managing the storage of the plurality of multimedia files within the disk array subsystem, and a playlist which includes a list of titles of specific multimedia files to be played at designated times. The multimedia server system advantageously includes synchronization parameters associated with each of titles specified by the playlist. The synchronization parameters are programmed to specify the manner in which particular files should be truncated in order to compensate for admission delays. An admission delay synchronization unit receives the synchronization parameters and truncates the multimedia files as specified by the synchronization parameters. In one implementation, a first synchronization parameter is used to specify that the current file should be truncated at the time for the play of the next file. A second synchronization parameter specifies that up to a given amount of time should be sacrificed at the beginning of the next file to account for the admission delay of the current file. In this manner, the beginning of the next file is truncated. Still a third synchronization parameter is provided to specify an amount of time up to which the current file will be truncated at it's end to account for it's admission delay. As a result, the truncated file can be played in a shorter amount of time than the scheduled duration, and the "excess time" created is available to absorb any admission delay.

A method for sensing and regulating the level of synchronization between a file of audit blocks generated in a primary host for transfer to a secondary host. The audit files in a primary host are divided into audit blocks which are each identified with an audit block serial number. The individual audit blocks are transmitted through a network from a primary host to a secondary host wherein a tracker mechanism monitors the difference between the number of received audit blocks and the number of generated audit blocks residing at the primary host waiting to be transferred. When the disparity between the audit blocks received and the generated audit blocks waiting to be transmitted reaches a certain critical level, the tracker mechanism will initiate an advance speed up program to expedite the transfer in order to bring the primary and secondary audit files into greater synchronism. Further, the acknowledgment level can be set to indicate the number of audit blocks received in the secondary host for information back to the primary host and the acknowledgment level can be utilized in order to preset a critical value which will indicate that the speed up transfer operation should be initiated.

A system and method for performing file synchronization in multiple nodes. The system includes a central node (120), and a plurality of local nodes (100) connected with the central node by a common communications network (110). Each local node includes a local application server (101), a local file server (103), and a local database (104). The central node includes a central application server (121), a central file server (123), and a central database (124). A synchronization program (122) running on the central application server downloads updated copies of files from the local file servers, and uploads the updated copies of files to the central file server as latest editions of the files. A proxy (102) running on each local application server updates copies of files in its respective local file server, and downloads latest editions of files from the central node.

An application independent method for monitoring file system requests made by any application program, storing changes made to a first copy of a selected file by the application program into a first file and synchronizing the selected file, whether the file is open or closed, with a second copy of the selected file. The monitoring and storing process is repeated each time a file system request to write into the selected file is made by the application program to track changes made to the selected file. At the time of synchronization, if the selected file is closed, all the changes that are stored in the first file are applied to a second copy of the selected file. If, however, the selected file is open, a portion of the changes are selected pursuant to a predetermined time period and applied to a second copy of the selected file. As a result, both copies of the selected files are identical, thereby synchronizing them. For open files, both copies of the selected file are identical up to the predetermined time period.

A system and method for distribution, replication, and management of files and their metadata across a network of file sharing servers for both preventative and promotion purposes relating to the particular content of the files. The system and method employ a process for dynamically distributing and replicating files across multiple file sharing computer servers using one or more synchronizing computer servers. Once distributed and replicated on a plurality of the file sharing servers, individual, or groups of replicated files are processed using a file modification application, a file input template containing metadata for each replicated file, and preset file destination template information present on each file sharing server. By using different destination template information on each file sharing server in the network, various protective and promotional aspects related to the files may be realized when used in a P2P or similar file sharing network environment.

A file includes data and semantic context. The semantic context identifies limitations on the use of the data in the file. Semantic context may include, among other possibilities, source information about a parameter, acceptable values for a parameter, presentation information, a record of the use of the data, and information to synchronize the use of the data with another file.

When the user works at home on his home computer, a work monitor logs his file activities on all the drives of his home computer in a work monitor log, which can be displayed in a work monitor window. The user can choose to update from the work monitor window. When update is selected, the files in the work monitor log are selected for file synchronization. When file synchronization is performed, files on the user's home computer are synchronized with corresponding files on the user's office computer. Preferably, the date and time of a file on the home computer selected for file synchronization are compared to the corresponding date and time of the corresponding file on the office computer to determine the direction of file synchronization. The newer version of the file overwrites the older version of the file on either the home or office computer. The file activities which qualify for logging in the work monitor log are selectable by the user as either accesses to the file, for example, reading a file without necessarily writing over it, or as file modification, which requires that the user writes the file. The generation of the work monitor log involves logging each file activity when the work monitor is enabled by the user. The user may wish to disable the work monitor for periods of time for various reasons. The user may select a variable time period for which log entries are maintained in the work monitor log, for example one week. Work monitor log entries are deleted from the work monitor after they have been in the work monitor log for more than the variable time period.
