  • Publication number: 20100306539
    Abstract: A method and system for controlling distribution of content through a communications network uses a second, parallel network for delivery of a transaction indicia to a requesting party. The use of the parallel network enables the transaction indicia to be forwarded to the party independently of the communications network, thereby reducing the probability of a party fraudulently obtaining delivery of the content. Additionally, information associated with the parallel network can be used to restrict distribution of the content to parties within a predetermined domain, such as, for example, a geographical region. The content may be delivered to the party in an encrypted form, preferably using an encryption algorithm and key designed to enable decryption of the content on only the content delivery device from which the request for the content was originated.

  • Publication number: 20060112092
    Abstract: Although negative example can be highly useful to better understand the user's needs in content-based image retrieval, it was considered by few authors. A content-based image retrieval method according to the present invention addresses some issues related to the combination of positive and negative examples to perform a more efficient image retrieval. A relevance feedback approach that uses positive example to perform generalization and negative example to perform specialization is described herein. In this approach, a query containing both positive and negative example is processed in two general steps. The first general step considers positive example only in order to reduce the set of images participating in retrieval to a more homogeneous subset. Then, the second general step considers both positive and negative examples and acts on the images retained in the first step. Mathematically, relevance feedback is formulated as an optimization of intra and inter variances of positive and negative examples.

  • Patent number: 6959056
    Abstract: In an adaptive filter for cancelling common-mode noise in digital subscriber loops, a narrowband noise estimator is used to detect one or more noisy frequency bands of the common mode signal and derive therefrom a first noise estimation signal. A wideband noise estimator derives from the remainder of the common mode signal a second noise estimation signal. The first and second noise estimation signals are subtracted from the differential signal, The wideband noise estimator comprises a bandstop filter for removing the frequencies detected by the narrowband noise estimator, an analog-to-digital converter for digitizing the bandstopped signal, and an adaptive filter for deriving the second noise estimation signal from the digitized bandstopped signal and, in the process, compensating for phase and gain differences, especially attributable to the interference being injected at different points along the length of the channel.

  • Patent number: 6940973
    Abstract: In order to overcome problems when using an adaptive filter for cancellation of common-mode noise in digital subscriber loops, caused by a portion of the differential signal being converted to common mode, which degrades the performance of the filter, a noise cancellation technique is proposed which compensates for this cross-coupled signal energy. In particular, a digital noise detector is used to detect one or more noisy frequency bands of the common mode signal and pass only the digitized common mode signal in those detected frequency bands through the adaptive filter to produce a digital common mode noise estimate signal. A control unit adjusts coefficients of the adaptive filter to reduce correlation between the differential signal and common mode signal. It is also proposed to compensate for the effects of stray capacitive coupling across the usual hybrid device by including an equivalent capacitive component in a common mode noise estimation circuit.

  • Patent number: 6687350
    Abstract: A smart card reader and transaction system which uses the voice path of a switched telephone network to effect smart card transactions are described. The smart card reader may be used with either a regular telephone or an ADSI telephone. If the telephone is not a handsfree set, the smart card reader is preferably connected between the base set and the handset. If the telephone is a handsfree model, the card reader is positioned between the base set and the switched telephone network. A smart card application server controls the smart card reader and switches it between a user mode and a card communications mode. Most applications software resides on the application server so that the smart card reader is simple to construct and inexpensive to manufacture. The advantage is a simple, portable, inexpensive yet reliable system adapted to be owned and used by the general public.

  • Publication number: 20040013255
    Abstract: A method and apparatus for efficiently utilizing resources in a switched telephone network by providing call treatment at the closest available resource to the calling party preventing holding up network connection through to the terminating location if resources are not available at call termination equipment to handle a call. The selected calls are locally parked pending the availability of service termination resources to handle the call. The availability of service resources at the termination is determined before a selected call is extended through the network. Advantageously while the call is parked call treatment discrimination can be performed.

  • Publication number: 20030235281
    Abstract: A method and apparatus for authenticating calling parties prior to call connection at a service facility uses the correlation of the call with a security message received over a data network. The correlation is made possible with an encoded string inserted into a field (such as the user-to-user information (UUI) field) of a call set-up signaling message used to initiate the call, and a correlate of the encoded string inserted into the security message. The authentication is provided at an authentication site that is logically separate from the service facility. The call is first connected to the authentication site, an authentication procedure is preferably selected and customized, and then performed. A security message is generated that includes information related to the client and the encoded string. The call is then disconnected from the authentication site, and reconnected to the service facility.
