  • Publication number: 20250390862
    Abstract: Securing digital assets in a vault that interfaces with multiple different third-party wallets to store keys/mnemonics. The vault interface accepts input from multiple different party wallets to combine multiple encryptions and secure storage techniques. Numerous cryptographic mechanisms are employed to securely pull a mnemonic phrase from a third-party wallet and into an institution's vault. A customer's mnemonic phrase is securely transported from a personal wallet into a secured institution's encrypted vault using the power of HSM to encrypt and decrypt a customer's mnemonic phrase securely.

  • Publication number: 20250286869
    Abstract: Systems and methods for protecting user data received by, stored on, and/or requested by third-party computing devices include a data entry computing system on a first network node. A data entry computing system can include a processing circuit that can identify user-entered data as sensitive user data, generate a content encryption key (CEK), generate encrypted user data by encrypting the sensitive user data with the CEK, tag the encrypted user data and the CEK with a tag readable by a database server on a network node different than the data entry computing system, the tag comprising information indicative of the encrypted user data, and transmit the encrypted user data to the database server, wherein the database server excludes a private key of a key manager on a network node different than the data entry computing system.

    Abstract: Systems and methods for protecting user data received by, stored on, and/or requested by third-party computing devices include a data entry computing system on a first network node. The data entry computing system includes a processing circuit configured to: identify user-entered data as sensitive user data, generate a content encryption key (CEK), generate encrypted user data by encrypting the sensitive user data with the CEK, and tag the encrypted user data and the CEK with a tag readable by a database server on a network node different than the data entry computing system. The tag includes information indicative of the user data. The processing circuit is configured to transmit the encrypted user data to the database server, wherein the database server excludes a private key of a key manager on a network node different than the data entry computing system.
