  • Patent number: 10885223
    Abstract: The disclosed computer-implemented method for anonymizing user accounts may include (i) receiving an instruction to anonymize a user account to protect a user's personally identifiable information, (ii) accessing, by a security program, a settings portal for the user account in response to receiving the instruction to anonymize the user account, (iii) replacing, by the security program, original values within at least two fields within the settings portal for the user account with anonymized values to mask the user's personally identifiable information, and (iv) storing the anonymized values within a protected vault to enable the user to login to the user account. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 10469469
    Abstract: Techniques are disclosed for providing a device-based PIN authentication process used to protect encrypted data stored on a computing system, such as a tablet or mobile device. A client component and a server component each store distinct cryptographic keys needed to access encrypted data on the client. The mobile device stores a vault encryption key used to decrypt encrypted sensitive data stored on the mobile device. The vault key is encrypted using a first encryption key and stored on the mobile device. The first encryption key is itself encrypted using a second encryption key. The second encryption key is derived from the PIN value.

  • Patent number: 9565192
    Abstract: IoT devices are secured on multiple local area networks. Each local network contains a router which monitors activities of IoT devices, and transmits corresponding information to a backend server. The backend amalgamates this information, calculates dynamic reputation scores, and determines expected authorized activities for specific IoT devices. Based thereon, the backend creates a constraint profile for each IoT device, and transits the constraint profiles to the routers for enforcement. Enforcing a constraint profile can include creating multiples VLANs with varying levels of restricted privileges on a given local area network, and isolating various IoT devices in specific VLANs based on their reputation scores. Constraint profiles can specify to enforce specific firewall rules, and/or to limit an IoT device's communication to specific domains and ports, and/or to specific content.

  • Patent number: 9384654
    Abstract: Locations of animate and inanimate items are tracked over time. Tracking policies concerning the items are enforced, based on detected spatiotemporal events. Multiple routers each maintain a captive network to which mobile computing devices automatically connect. Users register mobile computing devices, which are associated with items to be tracked. A backend server maintains records concerning registered mobile computing devices. Records contain identifiers of registered mobile computing devices and their associated items, as well as categorization information and tracking policies concerning the items. Over time, registered mobile computing devices are moved around, causing them to connect to and disconnect from different captive networks. These connection events are reported to the backend, which uses this data to track locations of items over time.
