Abstract: The present invention relates to a method for monitoring a bookmarked web page and a system and a computer program implementing such a method. A method according to an embodiment of the invention includes a first phase, including steps for storing, in association with each other, user identification data and an active version of the web page. The method further includes at least one iteration of a second phase, including a step for sending from user's browser to a network server a request for change information about the bookmarked web page since the stored version was active. On response of the server, if the web page has changed, the user has the possibility to choose to keep the stored old version of the web page or to accept the current version of the web page. The network server may be a server associated with the web page, e.g., a web site server, or an ISP server.

Abstract: A method and system for generating optimal itineraries based on network connectivity. A computer receives a first message from which a current position of a vehicle on a trip, destination, service(s) being provided to mobile device(s) in the vehicle, service provider(s) and network(s) are extracted. Optimal itineraries are generated by generating sets of optimal parameters that include paths for which connectivity measures satisfy predefined criteria and hops that indicate positions associated with connectivity changes. A response to the first message indicates the optimal itineraries and the associated sets of optimal parameters and is sent to a vehicle-based device. Sending the response results in the mobile device(s) making the connectivity changes when the vehicle is detected at the hops.

Abstract: A method for use when an original email is sent from an originator to a receiver, having a real email address, at a destination email address, which includes a concatenation of an alias and a magic number, is provided and includes replacing the destination email address with the real email address of the receiver, adding a new header field to the original email indicating that the destination email address was an original destination of the original email and forwarding the original email to the receiver at the real email address. If the receiver replies with a reply email, the method further includes setting a from header field in the reply email with a new header field indicating that the destination email address was an original destination of the original email, and if the original email is appended, removing the new header field from the original email.

Abstract: Data encrypted with a scrambling key Ks are transmitted from a service provider via a master device to a plurality of client devices having unique identifiers, administered by the master device. A set of partial keys comprising a respective partial key for each respective one of the plurality of clients is calculated at the service provider, by applying a predetermined function to the unique identifiers of all clients but for the identifier of the respective one of the plurality of clients. This set of partial keys is transmitted to the master device, which transmits to each respective clients the respective partial key calculated therefore. Each client can then derive the scrambling key from the respective partial key received from the master device by reference to its own unique identifier, and use the result to decrypt the data.

Abstract: A method and computer system for managing bandwidth in a content on demand service provided by a service provider to users. A request is received from a user to receive the content. If it is ascertained that a total number of users requesting the content within a predetermined time period is below a first specified threshold, then the user is connected to a unicast stream of the content. If it is ascertained that a total number of users requesting the content within a predetermined time period is not below a first specified threshold, then the user is connected to a first multicast stream of the content. A video carousel includes at least two multicast streams that contains the first multicast stream. Each multicast stream has been or will be initiated at a unique time slot of a time period that is equal to the time duration of the content.

Abstract: A sender sends an email message to a receiver. The message includes an avatar representing the sender. Upon receiving the message, if the receiver has a question related to the message, the receiver sends the question to the sender via the avatar. After receiving the question, the avatar remote server device correlates the question with the message through a MSG-ID associated with the receiver or avatar. The avatar remote server device parses and analyzes the question and then searches mailboxes, agendas, previous answers, toDoLists, folders, resumes, and/or address books of the sender to find a corresponding answer for the question. Then, the avatar remote server device provides the answer to the receiver via the avatar. Alternatively, upon receiving the question, the avatar remote server device sends a notification to the sender. If the sender has an online connectivity, the sender provides the answer to the receiver via the avatar.

Abstract: A method and system for generating optimal itineraries based on network connectivity. A computer receives a first message from which a current position of a vehicle on a trip, destination, service(s) being provided to mobile device(s) in the vehicle, service provider(s) and network(s) are extracted. Optimal itineraries are generated by generating sets of optimal parameters that include paths for which connectivity measures satisfy predefined criteria and hops that indicate positions associated with connectivity changes. A response to the first message indicates the optimal itineraries and the associated sets of optimal parameters and is sent to a vehicle-based device. Sending the response results in the mobile device(s) making the connectivity changes when the vehicle is detected at the hops.
