A computer implemented method comprising processing the unstructured objects of each record of records of a database for identifying a set of one or more values of attributes in the unstructured objects of the each record. The sets of unstructured attribute values of two records of the database may be compared for determining a similarity level between the two sets. It may be determined whether the two records are representing a same entity based on the comparison result.

Record matching in a database system

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.
