Method and System for Providing Password-free, Hardware-rooted, ASIC-based Authentication of a Human to a Mobile Device using Biometrics with a Protected, Local Template to Release Trusted Credentials to Relying Parties

Biometric data, which may be suitably transformed are obtained from a biometric input device contained within a stand-alone computer or a mobile device, which may contain an ASIC chip connected to or incorporated within the stand-alone computer or mobile device and which includes the capability for capturing one or more biometric samples and for biometric feature extraction, matching and encryption. For extra security, the biometric matching is used in conjunction with a PIN to authenticate the user to the stand-alone computer or mobile device. The biometric template and other sensitive data residing on the mobile device are encrypted using hardware elements of the mobile device (or the ASIC) together with the PIN hash and/or the Password hash. An obfuscated version of the Password, stored on the ASIC or the mobile device is de-obfuscated and released to the mobile device authentication mechanism, including a Trusted Platform Module if present, in response to a successfully decrypted template and matching biometric sample and PIN. A de-obfuscated password is used to authenticate the user to the mobile device and the same or a different de-obfuscated password may be used to authenticate the user to a remote computer using the SSL/TLS or a process based upon a symmetric encryption algorithm. The locally generated password may be used to encrypt data at rest on the mobile device or ASIC and the remote authentication password may be used to encrypt data in transit to and from a remote computer. This creates a trusted relationship between the stand-alone computer or mobile device and the remote computer. The system also eliminates the need for the user to remember and enter complex passwords on the mobile device or for secure transmission of data. A similar method may be used, with the signature/sign biometric modality to determine whether the holder of an IC chip card is, in fact the card owner.

System and method for permission confirmation by transmitting a secure request through a central server to a mobile biometric device

A system for permission confirmation incorporates a terminal device for transmitting an authorization request on a network. The terminal device includes capability for encryption of the request and for decryption of a response. A request arbitrating server (RAS) is connected to the network for receiving the authorization request from the terminal device. The RAS incorporates capability for decryption of the request from the terminal display and determines an authorizing party responsive to the request. The RAS then has capability for encryption of a request to an authorizing party for transmission on the network, and, for decryption of a response and biometric data from the authorizing party. The RAS has capability to confirm biometric data received and encrypt a response to the terminal device. A user biometric device (UBD) is connected to the network having capability for receiving an authorization request from the RAS and decrypting the request. A display for the decrypted request and a sensor for entry of biometric data along with an input device for entry of a response to the request is incorporated in the UBD. The UBD provides capability for encrypting the biometric data and response and transmission of the encrypted biometric data and response to the network for receipt by the RAS.

Fluorescent polymer superquenching-based bioassays

A chemical composition including a fluorescent polymer and a receptor that is specific for both a target biological agent and a chemical moiety including (a) a recognition element, (b) a tethering element, and (c) a property-altering element is disclosed. Both the fluorescent polymer and the receptor are co-located on a support. When the chemical moiety is bound to the receptor, the property-altering element is sufficiently close to the fluorescent polymer to alter the fluorescence emitted by the polymer. When an analyte sample is introduced, the target biological agent, if present, binds to the receptor, thereby displacing the chemical moiety from the receptor, resulting in an increase of detected fluorescence. Assays for detecting the presence of a target biological agent are also disclosed.

Stereoisomers of p-hydroxy-milnacipran, and methods of use thereof

ActiveUS7038085B2Equal potencyBiocideNervous disorderAdrenergicChemistry
The present invention relates generally to the enantiomers of para-hydroxy-milnacipran or congeners thereof. Biological assays revealed that racemic para-hydroxy-milnacipran is approximately equipotent in inhibiting serotonin and norepinephrine uptake (IC50=28.6 nM for norepinephrine, IC50=21.7 nM for serotonin). Interestingly, (+)-para-hydroxy-milnacipran is a more potent inhibitor of norepinephrine uptake than serotonin uptake (IC50=10.3 nM for norepinephrine, IC50=22 nM for serotonin). In contrast, (−)-para-hydroxy-milnacipran is a more potent inhibitor of serotonin uptake compared to norepinephrin uptake (IC50=88.5 nM for norepinephrine, IC50=40.3 nM for serotonin). The invention also relates to salts and prodrug forms of the aforementioned compounds. In certain embodiments, the compounds of the present invention and a pharmaceutically acceptable excipient are combined to prepare a formulation for administration to a patient. Finally, the present invention relates to methods of treating mammals suffering from various afflictions, e.g., depression, chronic pain, or fibromyalgia, comprising administering to a mammal in need thereof a therapeutically effective amount of a compound of the present invention.
