Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

Abstract: An example operation may include one or more of connecting, by a recipient node, to a source node via a blockchain network, receiving, by the recipient node, a data block, a digest of the data block encrypted by a private key of the source node, a public key paired to the private key and an IP address of the source node, calculating, by the recipient node, a digest of the data block, decrypting, by the recipient node, the digest of the data block by the public key, comparing, by the recipient node, the decrypted digest against the digest, and in response to a match, storing the encrypted digest, the public key and the IP address of the source node onto a ledger of the recipient node.

Abstract: An example operation may include one or more of connecting, by a committer node, to a main blockchain comprised of a plurality of initiator nodes, receiving, by the committer node, a transaction from an initiator node of the plurality of the initiator nodes and placing blocks of the transaction on the main blockchain, executing, by the committer node, a request from the initiator node of the plurality of the initiator nodes to branch off a sub-blockchain from the main blockchain, processing, by the committer node, the transaction in the sub-blockchain, detecting, by the committer node, a completion or an ending of the transaction in the sub-blockchain, in response to the detection of the completion of the transaction, committing the transaction to the main blockchain, in response to the detection of the ending of the transaction, terminating the transaction in the sub-blockchain, and discarding, by the committer node, the sub-blockchain.

Abstract: A topic based conversation retrieval system and method may include receiving a first conversation between a first plurality of users a second conversation between the first plurality of users or a second plurality of users, the second conversation being conducted on a second communication mode different than the first communication mode, analyzing the first conversation and the second conversation, determining one or more topics of discussion in the first conversation and the second conversation, and retrieving a portion of each of the first conversation and the second conversation, where the portion is related to a topic chosen to be retrieved.

Abstract: An example operation may include one or more of connecting, by a participating blockchain (BC) node, to a blockchain network configured to store a plurality of packages, selecting and downloading, by the participating BC node, a package containing a random code variant identified by a unique identifier (ID), executing, by the participating BC node, the package to calculate an outcome associated with the variant ID, receiving, by the participating BC node, votes on outcomes associated with the variant ID and votes on outcomes associated with different variant IDs from other nodes of the blockchain network, and analyzing, by the participating BC node, the votes to determine if the votes on the outcomes associated with the variant ID are different from the votes on the outcomes associated with the different variant IDs.

Abstract: Computer implemented methods are presented. The methods include, for instance: obtaining a user credential for login to a mobile device from a user. By use of a multi-layered authentication, based on the user credential, and a discreet user identity verification, the user determined to be unauthorized would operate the mobile device in a precaution mode, which discreetly creates secure records of activities of the user.
