    摘要： In an approach for authentication of a username, a processor maintains a mapping of usernames and realms. A processor receives a username and a time-based one-time password code (TOTP code) for the username based on an authentication application. A processor, upon receiving the TOTP code: determines a realm from the mapping based on the received username and the received TOTP; and requests an entry of a credential relating to the username in the realm. A processor, upon receiving of the requested credential, authenticates the username by determining that the received credential matches an expected credential for the realm.

    摘要： The present disclosure relates to a computer receiving a current training dataset. A first fraction of the training dataset comprises synthetic training data and a remaining second fraction of the training dataset comprising real-life training data. The real-life training data is user defined data and the synthetic training data is system defined data. A machine learning based engine is trained and may repeatedly be performed by using the current training dataset. In each iteration or a subset of the iterations, the training dataset is updated by adding real-life training data, thereby increasing the second fraction in the updated training dataset and reducing the first fraction of the synthetic training data.

    摘要： A system including a processor and a memory storing program instructions and a machine learning module. The machine learning module is configured for outputting one or more suggested data element change requests in response to receiving an initial data element change request. Execution of the program instructions causes the processor to receive the initial data element change request, receive the one or more suggested data element change requests in response to inputting the initial data element change request into the machine learning module, receive one or more subsequent data element change requests, detect if the one or more subsequent data element change requests contain the one or more suggested data element change requests, and provide an alert signal if the one or more suggested data element change requests are not detected within the one or more subsequent data element change requests.
