  • Publication number: 20130031476
    Abstract: A method and system is presented for providing information to a user interactively using a conversation manager thereby mimicking a live personal assistant. Communication between the user and the system can be implemented orally and/or by using visual cues or other images. The conversation manager relies on a set of functions defining very flexible adaptive scripts. As a session with a user is progressing, the conversation manager, obtains information from the user refining or defining more accurately what information is required by the user. Responses from the user result in the selection of different scripts or subscripts. In the process of obtaining information, data may be collected that is available either locally, from a local sensor, or remotely from other sources. The remote sources are accessed by automatically activating an appropriate function such as a search engine and performing a search over the Internet.

  • Publication number: 20020087976
    Abstract: A system and method are provided for delivering broadcast-quality video with targeted advertising to viewers over the switched communication network, thereby providing a viable alternative to traditional cable, over-the-air, and direct broadcast satellite delivery systems. According to one embodiment, program streams with appropriately inserted splice points are transmitted from a network head end node to one or more egress nodes via a switched network. Demographically-targeted advertising is then inserted into the program streams at the egress nodes for subsequent delivery to individual subscribers. More specifically, targeted advertising is inserted in a program stream using a splicing method that employs adaptive synchronization to align splice points in the program and advertising streams that are being spliced together. By appropriately aligning splice points, broadcast-quality video transmission via switched networks is achieved.

  • Patent number: 6064972
    Abstract: The risk of fraud associated with access by a subscriber to a network (42) is managed by a system that includes a data base (46) that stores a record for each subscriber indicative of that subscriber's usage history and payment ability for each service to which that subscriber has access. Additionally, the subscriber's record also stores an individual service risk characteristic indicative of the risk of providing access by the subscriber to a particular service, as well as a composite risk characteristic indicative of an overall risk of access. In response to a request for access to a particular service by a subscriber, the data base (46) responds in accordance with the subscriber's individual service risk characteristic for the service sought as well as the composite risk characteristic. In this way, account is taken of the subscriber's usage and payment ability with respect to all services available to the subscriber, rather than the single service sought by the subscriber.

  • Patent number: 5552897
    Abstract: A communication apparatus (e.g., a fax apparatus) provides secure message transmission by sending messages having an unrestricted portion (e.g., a header) and a restricted portion (e.g., the body of the message). The unrestricted portion is always outputted at the receiving apparatus; however, access to the restricted portion is provided only in response to receiving predetermined information from a user (e.g., a message recipient). This information may include either the use of a password or the use of a PIN code following the insertion of a user's smart card into the receiving apparatus. If the restricted portion is encrypted, the user must either provide the decryption key to enable the receiving apparatus to decrypt the restricted message or his/her smart card must perform the actual decryption of the restricted message.

  • Patent number: 5544246
    Abstract: A smartcard that allows different Service Providers to coexist on the smartcard with none of the Service Providers, nor the owner of the smartcard, having access to the files created for, or by, each of the resident Service Providers. The operating system of the smartcard includes a root directory that is owned by the smartcard's issuer/owner, and each Service Provider is a "user" that is installed by the issuer/owner. Each such user is provided with a subdirectory of the root directory, and within the subdirectory the user creates files and subdirectories with files, as the user deems necessary. The operating system prevents all users of the smartcard, including the smartcard's issuer/owner and the smartcard's holder, from accessing any files that are owned by any other user, when that user chooses to prevent such access. This power to exclude is effected through a password file that is owned by the user and which cannot be altered by any other user, including the smartcard's issuer/owner.

  • Patent number: 5541583
    Abstract: An updatable, interrogation system is provided for interrogating portable data cards. The interrogation system sequentially communicates with each portable data card as it comes within communication range in a first time period for determining a unique identification number associated with each data card. Once the identification number for a card is obtained by the interrogation system, a predetermined transaction, such as deactivating an electronic barrier to entering a limited access area, for the holder of the identified card is initiated. The interrogation system then completes each predetermined transaction of reading from and writing data to each one of the cards while communicating in a second time period. The present invention also discloses an interrogation system where a locking command is transmitted to the portable data card, which is subsequently disabled by a lock reset command issued by the interrogator in response to completion of the predetermined transaction.

  • Patent number: 5477215
    Abstract: An updatable, interrogation system is provided for simultaneously interrogating a plurality of portable data cards. Operable over a plurality of radio frequencies, the interrogation system sequentially communicates with each portable data card as it comes within communication range on a first one of the plurality of radio frequencies for determining a unique identification number associated with each data card. Once the identification number for a card is obtained by the interrogation system, a predetermined transaction, such as deactivating an electronic barrier to entering a limited access area, for the holder of the identified card is initiated. The interrogation system then selects and moves with each card to a different one of the plurality of radio frequencies for completing a data transfer portion of the transaction.
