Abstract: A method for privacy-preserving identity verification includes, at a computing node, receiving, over a computer network, a unique user identifier for a user within an online community, and a community identifier for the online community. An identity profile identifier is computer-generated based at least in part on the unique user identifier, the community identifier, and a nonce identification value. A network-accessible identity profile for the user is computer-generated, the identity profile including one or more verified identity claims for the user, and the identity profile indexed by the identity profile identifier.

Abstract: A computing system comprises a plurality of network computing devices, each maintaining an instance of a blockchain. The blockchain includes an ordered set of blocks, each block including one or more transaction entries and a cryptographic hash of an immediately preceding block. The blockchain further includes new participant introduction logic configured to add a transaction entry to a block of the blockchain. The transaction entry includes a blockchain account and a verifiable unique digital identity including a public cryptographic key.

Abstract: An integrated switching regulator device has a switching mode regulator comprising an input voltage source and a switching circuit coupled to the input voltage source configured to generate a pulsed voltage from the input voltage. A low pass filter is coupled to the switching regulator and is configured to filter the pulsed voltage to provide a regulated voltage to a load. The low pass filter comprises at least two LC stages, wherein the first LC stage comprises an air cored inductor and each subsequent LC stage comprises a non-air cored inductor. The switching circuit comprises two or more switching elements configurable to operate at a switching frequency of several megahertz.

Abstract: A system for credentialing a miner for a blockchain system is provided. The system interacts with a Trusted Witness to obtain a witness statement attesting to the identity of the miner. The witness statement includes a miner public key of the miner and a signed miner public key signed using the corresponding miner private key. The system provides to a notary the witness statement and signed bylaws signed using the miner public key. The system receives from the notary a digital identity signed by the notary that includes an identification of the notary, the witness statement, and the signed bylaws. The miner uses the digital identity when participating in mining for the blockchain system.

Abstract: A method and system for transmission of digital content via e-mail with point of use digital rights management is disclosed. The secured access rights to the digital content may be customized for individual recipients by the sender, and may evolve over time. The access rights are enforced according to a time-dependent scheme. A key server is used to arbitrate session keys for the encrypted content, eliminating the requirement to exchange public keys prior to transmission of the digital content. During the entire process of transmitting and receiving e-mail messages and documents, the exchange of cryptographic keys remains totally transparent to the users of the system. Additionally, electronic documents may be digitally signed with authentication of the signature.

Abstract: A control circuit (1) for controlling a FET (2) for outputting a 3.3 volt or a regulated 1.5 volt output to an AGP bus on a PC motherboard in response to a TYPEDET signal being applied to a control terminal (3) of the control circuit (1) through an input (6) of a voltage divider circuit (8). The TYPEDET signal is received from a video card receiving slot and indicates the type of video card in the slot of the motherboard. An amplifier (20) outputs a control signal to the gate of the FET (2) for either disabling the FET (2), or enabling the FET (2) to output the 1.5 volt or the 3.3 volt outputs. A decoding circuit (30) decodes the state of the control terminal (3) and controls the amplifier (20) to disable the FET (2) during power up. When the TYPEDET signal of zero volts, the FET (2) is operated to output the 1.5 regulated voltage output. When the TYPEDET signal is floating, the FET (2) outputs the 3.3 source voltage.

Abstract: An IC monitoring chip (10) for remotely monitoring the output of a thermal diode (5) formed in the substrate of a CPU (2) for monitoring the temperature of a thermal plate (3) of the CPU (2) comprises a signal conditioning circuit (12) which relays the output from the diode (5) to an analog-to-digital converter (14), which in turns outputs a two's compliment signal to an adder (22). The adder (22) adds the two's compliment signal to a temperature offset value stored in a temperature offset register (17), which compensates for the temperature difference between the diode (5) and the thermal plate (3). Comparators (24) and (25) compare the output from the adder (22) with upper and lower predetermined temperature limits in upper and lower limit registers (19) and (20) for determining the temperature of the thermal plate (3). The temperature offset value is stored in ROM (35) of the computer (1) and is written to the register (17) each time the computer (1) is powered up.
