  • Patent number: 8806586
    Abstract: A device for identification and authentication of a remote user connecting to a service over a network includes a cryptographic processor and at least one cryptographic key and storage means, additional processing means and interface means to generate and transmit a unique authentication code as emulated keystrokes through a standard input, means of a client terminal.

  • Patent number: 8673214
    Abstract: A portable apparatus for measuring a glucose level of a user having: a card-like member; a processor within the card-like member; at least one glucose sensor comprising a reagent, the glucose sensor generating a signal indicative of a measured glucose level upon application of a blood sample to the glucose sensor, wherein the glucose sensor is fixed to the card-like member and operably coupled to the processor; and at least one cover alterable between a first position in which the glucose sensor is covered and a second position in which the glucose sensor is exposed for use.

  • Publication number: 20070278285
    Abstract: The invention concerns a secure data management device and a method for providing communication between a remote device in a chain of logistics and a host computer via a data network which ensures the identity, authenticity, integrity and confidentiality of collected information. This is provided by an item which is attached to a product subjected to a chain of logistics. The item can collect information about the product or use of the product and communicates such information to a host computer via a data network in a secure manner, which will assure the recipient of the information that the communication is made with the correct item and that the information communicated has not been manipulated and the transmission is protected from eavesdropping. The information collected by the item can be generated by sensors integrated or attached to the product.

  • Patent number: 7170409
    Abstract: A packaging and a method for monitoring a packaging (10) of a disposable material in a chain of logistics. As an integral part of the packaging, the packaging has an electronic module (12) comprising electric energy supply means, data processing means, data storage nonvolatile memory means for storing information related to the packaging, time keeping means, and data transceiver means for transmitting and receiving said information in communication with a host computer (30). The electronic module also has sensor means (14, 20) for detecting a changed physical condition of the packaging and for signaling information representing said changed physical condition to the electronic module (12) to be stored in the memory means together with a notation of time from the time keeping means.

  • Patent number: 6628199
    Abstract: A response form containing a means of input that on manual influence can switch a conducting electrical circuit connected to an electronic unit (40) incorporated into the response form for registration of the said influence. The present invention provides such a response form at low cost and enables the use of the response form as a patient journal. The patient journal also can be integrated with a pharmaceutical response package. The response package is formed of a disposable material in the form of a sheet (12), and a conducting circuit (26) is printed onto one side (16) of the disposable material. The means of input can consist of circuit makers (30, 32) that are visually marked-on one side of the disposable material and that are arranged to make electrical contact across an interrupted loop (28) of the conducting circuit (26) upon pressing together localized inner surfaces (14, 16) of the disposable material which face each other.

  • Patent number: 6616035
    Abstract: A method and a device of identification and authentication of a holder of a mobile electronic transaction device in an electronic transaction process between a transaction service provider and a transaction terminal in communication via a computer network. A transceiver is adapted for transmitting an identity of the device to the transaction terminal and receiving a challenge transaction identifier from the service provider via the transaction terminal. A data processing device is adapted for determining an authenticity of a user identification input by comparison with a reference user identification, and for performing a cryptographic transformation of the transaction identifier using a secret key only on the identification input being determined as authentic. The transceiver is also adapted for transmitting a response result of the cryptographic transformation to the service provider via the transaction terminal for validating the transaction.

  • Patent number: 6615023
    Abstract: A low-cost system for wireless, bi-directional transformation of electric signals over a capacitive interface between a host unit and a guest unit is provided. The system allows a high impedance in the circuitry of the guest unit to obtain a good signal transfer ability in conditions of poor dieelectric materials, poor conductivity in the contact pads and relatively large gaps between the contact pads. The capacitive interface comprises a respective first (A1; B1), second (A2; B2) and third (A3; B3) conductive area in the host and guest units (10,40). The first conductive area (A1) of the host unit is connected to a self-tuning frequency generating resonant circuit (16) in the host unit (10) for obtaining high gain of signals transmitted to the guest unit (40). The second and third conductive areas (A2, A3) of the host unit are connected to an impedance circuit (30) in the host unit for receiving signals from the guest unit.
