The present invention is a method and a system that uses privacy-preserving distributed data stream mining algorithms for mining continuously generated data from different network sensors used to monitor data communication in a computer network. The system is designed to compute global network-threat statistics by combining the output of the network sensors using privacy-preserving distributed data stream mining algorithms.

The present invention provides for an improved method and system for determining differences in data sets or data files, expedited data transfer and data reconciliation in a communication network using hash segmentation processing. The system and method provides for an efficient means of communicating updated files, new revisions or verifying files between a source host and a target host. By implementing hash segmentation processing, and in many embodiments iterative hash segmentation processing, the updates within the files can be isolated for the purpose of minimizing the amount of data communicated from the source host to the target host. The system and methods provide for the transfer of data between two hosts in instances in which neither host is aware of the revision that exists on the other host. The hash segmentation process may implement a logarithmic hash approach or a sliding linear hash approach.

Session data is encoded in a tag-length-value format and encrypted using a modified encryption key. A session cookie is then formed by concatenating the length of the length of the secret, the length of the secret, the secret itself, and the encoded and encrypted configuration data. The session cookie is transmitted from a server computer to a client computer, where it is stored.

A mobile communications system transporting messages between mobile terminals and a central control center using a satellite communications system. The central control center and the mobile terminals each store a plurality of message display forms each having a form identifier and a predetermimed display format. The message display forms are selected as templates for generating user messages including message data supplied at the originating station. The satellite messages transmit the user message by transmitting the message data and the form identifier of the corresponding selected message display form. The receiving station, upon receiving the satellite message, accesses the message display form from memory in response to the supplied form identifier, and combines the accessed message display form with the message data to recreate the user message. The mobile terminals are designed as low-cost data terminals requiring a minimum amount of memory. The mobile terminals include a satellite transceiver, a graphic user interface providing a display and accepting key inputs from the user, and a software system including an application layer providing all messaging functions for the user and a middleware layer controlling transport of messages between the application layer and the satellite transceiver. The application layer operates as an event-based state machine, and includes an event handler that controls the application layer operations in accordance with the processing capacity of the middleware layer.

A sequence of symbol operations (a “schedule representation”) within a data storage device, wherein the operations are those used to process encoding or decoding operations of a forward error correction code (an “FEC code”) upon an arbitrary block of data of a given size (where size can be measured in numbers of symbols). The method is such that the schedule representation can be used to direct the processing of these operations upon a block of data in a way that is computationally efficient. Preferably, the same method can be applied to represent schedules derived from multiple different algorithms for the encoding or decoding of a code or for multiple different codes.

A method and system for mirroring and archiving mass storage. A primary mass storage and a secondary mass storage are synchronized to contain the same data. Thereafter, a primary system tracks changes made to the primary mass storage. These changes are consolidated periodically into update files, the consolidations representing changes made to the primary mass storage during a time interval that ends when the primary mass storage is in a logically consistent state. These update files contain only those changes necessary to represent the modified state of the primary mass storage at the time of the update. The primary system then transfers the update files to a secondary system to bring the secondary mass storage current with the primary mass storage. The consolidation minimizes the amount of information that must be transferred and therefore allows for a relatively low band width communication channel. In addition, update files may be cached by the primary system so that requests for mirrored or archived data may be fulfilled by the primary system cache rather than requiring access to the secondary system.

The invention provides a method of providing positioning data to a mobile user device comprising a positioning module for estimating a location of the mobile user device, the method comprising: providing a database comprising positioning data for use by the positioning module of the mobile user device to estimate the location of the mobile user device; providing customised user data specific to a user of the mobile user device; selecting one or more subsets of positioning data from the positioning data provided in the said database responsive to a determination that the said subsets of positioning data meet one or more relevance criteria relating to the said customised user data; and providing the selected subsets of positioning data to the mobile user device.

A method of controlling the flow of data, in respect of a given mobile terminal, between a Radio Network Controller (RNC) and a NodeB of a UMTS Terrestrial Radio Access Network (UTRAN) where an Automatic-Repeat-Request (ARQ) mechanism is implemented between the NodeB and said mobile terminal to provide for the retransmission of unsuccessfully transmitted data. The method comprises generating control messages at the NodeB and sending these control messages to the RNC, each control message enabling the RNC to identify which data should next be sent to the NodeB.

Data indicative of the durations of multiple instances of different phases of a traffic control signal in a given time period is determined. The data is used to obtain data indicative of a distribution of the durations of each phase. The distribution data is used to obtain data indicative of a probability of the traffic control signal having a given phase at one or more future time. The probability data may be used to provide an expected waiting time when arriving at the signal at a future time and/or a speed recommendation for a vehicle approaching the signal.

In a content delivery system, a gatekeeping apparatus is connected to a network. Prior to the transmission of a request message to a content server, a user terminal transmits an enquiry message to the gatekeeping apparatus. In response, the gatekeeping apparatus makes a decision as to whether or not a content can be retrieved from the content server and performs control on the transmission of the request message according to the decision. If the decision indicates that a content can be retrieved, the user terminal transmits the request message to the content server. In a preferred embodiment, the gatekeeping apparatus makes comparison between user's preference data and server's policy data and determines whether the requested content can be retrieved from the server. A cache memory may be provided in the user terminal or gatekeeping apparatus to store past decisions regarding requested contents.

A novel IOT network, methods of making, structure and functions, and method of use are disclosed.

A method and apparatus for synchronization of contents in a cloud service system for a mobile environment is provided. The synchronization method of a cloud service system includes uploading, at a device when data is changed, the changed data to a server, processing, at the server, the uploaded data, storing, at the server, the processed data along with a time change, transmitting, at the device, a synchronization request signal including a most recent server connection time at a predetermined time, downloading, at the device, a data log on data changed between the most recent server connection time and the current time, synchronizing, at the device, the data based on the data log, and updating the most recent server connection time.

Networks, particularly home networks, may be implemented using peer-to-peer technology. To relieve the user from administrative tasks, some configuration routines for such networks may be automated. Therefore a peer-group selects one of its peers as negotiation peer, having the task to communicate with single other peers or negotiation peers from other peer-groups. When adding or removing single peers, or merging or splitting peer-groups, the group label is usually modified. But it may be advantageous to keep the group label, especially if that label is known to other peer-groups. If a new peer-group in a peer-to-peer network is created by merging or splitting other peer-groups, a method for selecting a group label for the new peer-group comprises determining a negotiation peer, exchanging information between the negotiation peers in the case of merging, comparing features of the two peer-groups and based on the comparison assigning the label of one of the peer-groups to the new peer-group.

Methods and apparatus for modifying a data stream of backup data to be provided to a fixed position delta reduction backup method are disclosed. When the data stream is received, at least a portion of the data stream is parsed into a plurality of data blocks and a plurality of sets of validation bytes, wherein each of the plurality of data blocks corresponds to one of the plurality of sets of validation bytes. One or more modified data streams are then generated such that the plurality of data blocks are separate from the plurality of sets of validation bytes.

In a mobile positioning system, mobile user devices carry out data validation on locally stored positioning data, regulating the positioning data provided to a positioning module and selectively requesting updated positioning data from a central database. A controller receives requests for updated positioning data and selectively responds with updates. The mobile user devices store observations data concerning measurements of signals from electromagnetic signal sources and transmit data about the locally stored observations data to the controller. The controller then selectively requests transmission of the locally stored observations data and the mobile user device determines when and whether to transmit that data. The amount of positioning data which must be transmitted to and from the mobile user device and the overall power consumption of the mobile user device is reduced. The decision as to what observations data to transmit to the controller is distributed between the mobile user device and the controller.
