Patent attributes
A computer-implemented method is disclosed. The method includes: authenticating a user for login to a service for a first authenticated user session; in response to authenticating the user, generating a first data string associated with a first validity period; sending, to a client device associated with the user, the first data string; receiving, from the client device, a data access request to access a first data set at a remote data source, the data access request including the first data string; determining that the first authenticated user session has been terminated at a time of receiving the data access request; validating the first data string based on checking the first validity period; and in response to determining that the first authenticated user session has been terminated and that the first data string is valid, transmitting, to the client device, a data access response including at least a subset of the first data set.
