    摘要: Techniques are described for managing devices, such as Internet of Things (IoT) devices, using smart contract(s) on a distributed ledger (e.g., blockchain). Smart contract(s) executing on a distributed ledger may control access to one or more devices in a home or other environment. The smart contract(s) may employ information stored on the distributed ledger and information in a transaction sent to the smart contract(s) to determine whether particular user(s) and/or process(es) may access the device(s), issue commands to the device(s), access data generated by the device(s), and/or control the device(s). The smart contract(s) may provide a secure portal through which user(s) and/or service(s) may access device(s) for command and control of such device(s), and secure access may be based on permission information that is specified or provided by an owner or operator of the device(s) and that is stored on the distributed ledger.

    摘要: Techniques are described for determining account features based on a risk assessment. A first set of account features may be determined, including security feature(s) such as mode(s) for authenticating and/or verifying the identity of a user associated with account(s). Based on the first set of features, a risk metric may be determined for the account(s). The risk metric may indicate a risk that fraud may be committed against the account or using the account. Based on the determined risk metric, a second set of account features may be determined for the account(s). The first and second sets of account feature(s) may be applied to the account(s). Disabling a particular feature may cause a reevaluation of the risk metric and a redetermination of the feature sets to be applied to the account(s).

    摘要: Methods and systems for enrolling a user in an authentication program. In some embodiments, voice interaction that includes a request or command is received from a user. The user may be requested to provide authentication information to fulfill the request or command made during the voice interaction. The user may be authenticated using a first authentication method. The user may be passively enrolled into an authentication program that uses a second authentication method. Enrolling may include deriving characteristics of the user's voice from the voice interaction. After the user is enrolled in the authentication program, the second authentication method may be used to authenticate the user prior to fulfilling requests or commands made during voice navigation.
