Abstract: An apparatus may include a processor that may be caused to access handholding information indicating a hand configuration in which the apparatus is being held and compare the handholding information with previously-stored handholding authentication data of an authentic user. The previously-stored handholding authentication data may represent an authentic configuration in which the apparatus is held by the authentic user. The processor may be caused to determine that the apparatus is being held by the authentic user based on the comparison and cause an authenticated action to occur based on the determination.

Abstract: To write forgettable data to a blockchain, the forgettable data is transmitted to a server, from which encrypted data corresponding to the forgettable data are received. A hash of the forgettable data is generated. A data block including the encrypted data and control data including the hash is added to the blockchain.

Abstract: A method includes, by a computer associated with a security reporter, updating a component vulnerability entry blockchain to represent a state of a component vulnerability entry of a software component vulnerability database. The method includes, by the computer, providing the updated component vulnerability entry blockchain to a management authority so that the management authority updates a master blockchain for the software component vulnerability database. The updated master blockchain includes a plurality of component vulnerability entry blockchains, which represent corresponding states of component vulnerability entries of the software component vulnerability database, including the updated component vulnerability entry.

Abstract: A technique includes determining, by a computer, entries of a software vulnerability database that is associated with a plurality of components associated with a release of a software product. The technique includes determining, by the computer, a block of a blockchain representing a vulnerability state of the plurality of components; and associating, by the computer, the block of the blockchain with the product release.
