Abstract: The present technology can provide decentralized security and data management using a decentralized system to generate a cryptography key for decrypting data and using a smart contract to determine access to the cryptography key. The system obtains a request associated with a cryptography key (e.g., a request to decrypt data), and the request indicates the user's identity, a smart contract, and the identity of the key. The system checks a smart contract on a blockchain to determine whether the access conditions are satisfied for the smart contract. When access is authorized, the system generates a derived, cryptography key using a threshold of independent parties (e.g., key servers and/or members of a multi-party computation (MPC) committee). Threshold cryptography can be used in which t-out-of-n independent parties are required to generate the derived key.

Abstract: The present technology can allow a user to use a zero-knowledge authenticator (zkAt) to login to an account while preserving privacy of the authentication policy. More specifically, the present technology describes several implementations of a zkAt to enable policy-private authentication and to enable oblivious updates to authentication policies. The zkAt can be, for example, a zero-knowledge proof system where the underlying relation in the policy predicate remains private.

Abstract: Some aspects relate to technologies for employing generative models to produce personalized content based on insights extracted from user data. In accordance with some aspects, user data for an end user is accessed, and a plurality of insights are extracted from the user data. A prompt is generated using at least a portion of the insights. The prompt is provided as input to a generative model, causing the generative model to generate content. A message based on the content from the generative model is provided to a user device of the end user.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for confidential NFTs. For example, an example of a process for transferring ownership of an at least partially obfuscated NFT can include at least partially encrypting an NFT. The process can further include associating the at least partially obfuscated NFT with a smart contract that defines conditions under which the at least partially obfuscated NFT will be transferred to a buyer with a decryption key to decrypt the at least partially obfuscated NFT. The conditions ensure that a clear portion of the at least partially obfuscated NFT is part of the at least partially obfuscated NFT. The process includes receiving a request from a buyer to purchase the at least partially obfuscated NFT. Further, the process can include executing, based on receiving the request, the smart contract to complete the transaction based on the conditions of the smart contract.

Abstract: The present technology can allow a user to use the OpenID Connect protocol to login to an account that has an anonymous user account ID. More specifically, the present technology can programmatically combine information received from an OpenID provider during the OpenID Connect protocol with a random value to yield a unique anonymous user account ID. The present technology also makes use of the ability within the OpenID Connect protocol to embed a chosen nonce into the token signed by the OpenID provider. This allows for embedding hashes of cryptographic keys, like signature verification keys, into ID tokens received from the OpenID provider that authenticates the user. Subsequently, the user can sign messages that can be verified using the verification key bound to the ID token from the OpenID provider.

Abstract: A computing system is configured to access a first set of data associated with a first plurality of donors and a second set of data associated with a second plurality of persons in need. The computing system is further configured to receive an indication from a first device associated with a donor, indicating at least (1) one or more items available for donation by the donor, (2) a first location where the item is located, and (3) a time when the item is ready to be picked up at the first location. The computing system is further configured to select one or more persons in need among the second plurality of persons in need based on the first location and one or more second locations of the second plurality of persons in need, and send a notification to one or more second devices associated with the persons in need.

Abstract: A smart computer pointing device includes a body having a top surface and a bottom surface. The top surface includes one or more touch-sensitive areas configured to detect one or more touch inputs. The bottom surface is configured to be in touch with a flat surface. The smart computer pointing device further includes at least one of (1) a motion sensor disposed at the bottom surface configured to detect a motion of the body relative to the flat surface, (2) a wheel configured to rotate in response to a scrolling operation, (3) a display overlaid with at least one of the one or more touch-sensitive areas, (4) a speaker, (5) a microphone, or (6) a biometric sensor. The smart computer pointing device is configured to convert sensing data generated by the sensors into control signals and transmit the control signals to a computer system for controlling a graphical user interface.

Abstract: The lysine riboswitch is a target for antibiotics and other small molecule therapies. Compounds can be used to stimulate, active, inhibit and/or inactivate the lysine riboswitch.
