Computer-implemented methods and systems are provided for blockchain-mediated user authentication. Consistent with disclosed embodiments, authentication may comprise operations including receiving, from a user system, an authentication request for a user. The operations may also include determining a root system for the user using a blockchain, and redirecting the user system to the root system. The operations may include receiving, following redirection, a verification message indicating that the root system successfully authenticated the user, and including an authorization code for receiving, from the root system, a root system secret. The operations may include receiving from a database, identification data using the root system secret. Determining the root system may comprise identifying, using the authentication request and index information stored in the blockchain, a block of the blockchain storing root system information for the user. Receiving the identification data may comprise retrieving identification data from the database.

Blockchain systems and methods for user authentication

Systems and methods are provided for authenticating an identity of a user requesting a resource or service from an entity. In some embodiments, a system may include at least one processor; and a non-transitory medium containing instructions that cause the system to perform operations. The operations may include receiving credential information associated with the remote user, and receiving, from the server associated with the entity, first hash information. The operations may also include generating second hash information based on information associated with the user, comparing the first hash information with the second hash information, and transmitting an indication based on the comparison to the server associated with the entity.

Systems and methods for secure remote identity verification

In some implementations, a system may obtain a first model that is trained to identify feature data associated with a client system using one or more services of a service platform. The system may train, based on the feature data, a second model to identify anomalies associated with devices accessing the one or more services in association with a client identifier of the client system. The system may receive access data associated with an acting device accessing a service of the service platform. The system may determine, using the second model, that the acting device accessing the service corresponds to potential anomalous activity based on the access information. The system may obtain, from a verification device, a verification that the acting device accessing the service is anomalous activity. The system may perform, based on obtaining the verification, an action associated with the acting device.

Detection of anomalies associated with fraudulent access to a service platform

Computer-implemented systems and methods for user authentication based on blockchain technology. The authentication may comprise operations including receiving, from a user system, an authentication request for a user. The operations may also include determining a root system for the user using a blockchain, and redirecting a member system to the root system. The operations may include receiving, following redirection, a verification message indicating that the root system successfully authenticated the user, and including an authorization code for receiving, from the root system, a root system secret. The operations may include receiving from a database, identification data using the root system secret. Determining the root system may comprise identifying, using the authentication request and index information stored in the blockchain, a block of the blockchain storing root system information for the user. Receiving the identification data may comprise retrieving identification data from the database.
