Abstract: Techniques for authorizing a transaction or interaction of a user that is modified by authentication information for the same user are described herein. In embodiments, an authorization request message for a transaction and a session identifier may be received from a transport computer or a resource provider computer. A portion of pre-analyzed data about the user and the one or more interactions may be obtained, from a database, based on the session identifier. A risk analysis for the transaction using the portion of the pre-analyzed data may be performed to generate a value. The authorization request message may be modified to include the portion of the pre-analyzed data and the value. The modified authorization request message may be transmitted to an authorizing computer.

Abstract: System and method for establishing simultaneous zones of control for various communications to and from a computing devices based on specific criteria corresponding to more than one zone of control encompassing similarly-situated network locations. A browser (or any other common term for a networked computing session GUI) executing on a computing device may establish several zones of restricted data interaction based on specific user-defined criteria, thereby establishing simultaneous zones that respectively correspond to one or more specific parameters with regard to networked computer interactions. For example, a first zone may be associated with only other computers located in the United States (as determined by DNS records and the like) and a second zone may be associated with only other computers located with a specific domain (e.g., www.mybusiness.com).

Abstract: Various aspects include a wearable audio device having active noise reduction (ANR), where the ANR device includes: a feedback microphone; an electroacoustic transducer; and a feedback compensator configured to output a noise reduction signal to the electroacoustic transducer in response to a feedback signal from the feedback microphone, wherein the feedback compensator includes a tunable filter that modulates a loop gain in response to an adverse low frequency event being detected in the noise reduction signal outputted from the tunable filter, wherein the tunable filter is configured to maintain a substantially similar loop gain shape near a low frequency cross-over as the low frequency cross-over changes during loop gain modulation.

Abstract: System and method for extending zones of control through a hotspot for communications to and from computing devices based on specific criteria corresponding to zones of control. An encrypted virtual private network (VPN) for a browsing session may be established at a first computing device and remote server computers matching the parameters of the established zone. Then, a user of the first computing device may further establish a wireless hotspot network suited to allow additional remote computing devices to piggy-back on the one or more established encrypted virtual private networks. Thus, other connected devices using the hotspot connection to reach a broader computer network (e.g., the Internet) are then also taking advantage of the encrypted VPN being provided by the host of the hotspot. Each connected computing device may then also have various communications isolated through zonal control from the hotspot device.

Abstract: A method and structure are provided for implementing manufacture of a printed circuit board (PCB) with one of an infrared (IR) reflective mask or a novel solder mask to minimize coefficient of thermal expansion (CTE) mismatch between PCB laminate and plated through hole (PTH) copper. At least one of an IR-reflective mask and a solder mask composition for use in IR reflow processes is created such that radiant heat is reflected away from the major portion of the PCB yet permitted to impinge upon the PTHs. The copper within the PTH expands due to radiant heating while the bulk laminate expansion is significantly reduced due to the reflected IR radiation. Consequently, the CTE mismatch is minimized and tensile strain of the copper in the PTH is reduced, providing enhanced reliability.
