Abstract: A computer-implemented method, in a communication framework in which each of a plurality of users has one or more devices associated therewith, and in which the users use at least some of their devices to communicate via a backend system. A first user has a first set of first one or more associated trusted devices, and a second user has a second set of second one or more trusted devices associated therewith. The first user forms a first trust relationship between a first device in the first set and a second device in the second set. Based on (i) the first trust relationship, and (ii) the second set associated with the second user, the first user forms a second trust relationship between each device in the first set and each device in the second set. A least one device in the first set communicates with one or more devices in the second set based on the second trust relationship.

Abstract: Systems, computer program products, and methods are described for creating a multi-device functional code logit component allowing for multiple device communications on a distributed platform. As such, the invention allows for multiple wearable devices to each possess a unique non-fungible token (NFT) within a private distributed ledger. Each wearable device on has a unique immutable identity NFT. The grouping of NFT associated wearable devices are linked together for consensus resource distribution. Upon an initiation of a resource distribution request from a user using the user's wearable device, the other users in the distributed ledger group receive coded communications of the initiated resource distribution requiring an action approval request. If accepted action and a consensus is generated among the distributed ledger, the resource distribution is granted to the requesting wearable device.

Abstract: The presently disclosed technology is directed to combatting data theft, particularly of verified authentication data (or hashes thereof) such as login information, thumbprint data, digital signatures, identification numbers, and any other data that should be known to an accessor of stored data. The verified authentication data is initially saved for later comparison in a new type of memory, write-and-compare-only memory, where the data may be queried as to whether a to-be-verified value matches the stored verified value, but the stored and verified data is not read from the write-and-compare-only memory. This prevents a data breach by preventing the verified authentication data from being read by anyone, including those with access (whether legitimate or illegitimate) to any system connected to the write-and-compare-only memory.

Abstract: A user authentication method in a distributed processing system commences by receiving, at a first processing unit (108), a request (1004) to initiate an authentication session, wherein the request includes a unique identifier of a user requiring authentication. The first processing unit acquires at least one item of authentication data (412, 1712), which is valid during the authentication session. The authentication data is transmitted (1006) to a second processing unit (106) which is associated with a terminal device operated by the user. The second processing unit transforms the authentication data using a transformation algorithm based upon one or more session-specific authentication factors (404, 1704), to generate transformed authentication data that is characteristic of the authentication session and of the user.

Abstract: An authentication process for an endpoint device uses a pair of tokens. Tokens are generated at an authentication server that maintains a data store of token states, where the states are defined to include a “normal” state sequence along which a token is expected to advance. The endpoint device can store a token pair in non-volatile local storage. To authenticate, the endpoint device can provide its stored token pair to the authentication server, which can determine whether authentication succeeds based on the states of the tokens in the token pair. After successful authentication, the authentication server can provide a new token pair to the endpoint device and advance the token states along the normal sequence. When the endpoint device confirms receipt of the new token pair, which replaces the previous token pair, the authentication server can advance the state of the tokens again.

Abstract: Examples disclosed herein relate to securing a controller of a device. The controller is to determine whether a network interface of the device is connected to the Internet.

Abstract: A system and method for facilitating authenticating a client application to enable communications with another server-side application running on a server in communication with the client application (client). An example embodiment involves providing an authenticator for the client to a shared library that is accessible to the client and server, and then registering the authenticator for the client at the server. After registration, the client sends a request message (addressed to a server-side application) and token to the server. The token is derived using the authenticator at the shared library. The server then uses the token to check that the authenticator associated with the received token is registered. The server then communicates with the shared library to authenticate the client by verifying that the received token identifies the client that has provided the authenticator to the shared library. Client identity is then set to enable communications with the server-side application.
