The invention relates to a computer storage device, system, and method for secure offline authentications. An authentication device receives an authentication attempt from a user mobile device, decrypts an encrypted user identifier, and receives a two-factor authentication (2FA) code from a user. The device validates the authentication attempt based on the decrypted user identifier and the received 2FA code offline. The device tracks the number of validated authentication attempts and compares it to a threshold. When the number of validated authentication attempts exceeds the threshold, the 2FA code is automatically shared with a second computer storage device, allowing the user to validate an authentication attempt with both devices without inputting the 2FA code. The same entity controls both the computer storage device and the second computer storage device.

Methods and systems for accurately identifying and tracking electronic devices communicating across heterogeneous networks, even when those devices utilize multiple in-device network interfaces and change identifiers. The system receives network activity indications from various devices, each indication associated with a specific network interface and identifier. A correlation process, potentially employing a machine learning model, analyzes these indications to identify a sub-set originating from a single physical electronic device, spanning at least two different in-device network interfaces (e.g., cellular and Wi-Fi). A unified device identity, a persistent digital representation (or “digital twin”) of the device, is generated based on this correlated sub-set. This unified identity remains associated with the physical device regardless of interface changes, enabling consistent application of security policies, improved network visibility, accurate device tracking, and efficient resource allocation. The system handles both mandatory identifiers, which are associated with specific in-device network interfaces, as well as weak transitory identifiers.

A head-wearable apparatus improves user interactions with virtual interface elements in augmented reality (AR) environments. The apparatus tracks hand movements in 3D space, calculating velocity vectors and positions of fingers. For each virtual interface element, it determines a UI-to-finger vector and calculates alignment with the finger's velocity vector. Interaction zones are dynamically adjusted based on this alignment and velocity magnitude. The system evaluates consistency between finger movement and element locations to predict intended targets. Interactions are triggered when fingers enter adjusted zones of predicted targets. This approach reduces erroneous selections and improves interaction accuracy, even for closely-spaced elements. The invention applies to various AR scenarios, enhancing user experiences in applications like gaming and education.
