An example method includes receiving a request for a transaction; associating the request with a user; receiving, from the user, identification information; retrieving, from a database, first stored authentication information associated with the user; retrieving, from a distributed ledger, second stored authentication information associated with the user; and determining that the received authentication information matches the first stored authentication details and the second stored authentication details and, in response, outputting, by the computing system, a proof of authentication to enable the transaction.

Techniques are disclosed relating to retaining a log entry in response to detection of a respective triggering event occurring within a computer network. This triggering event may result in a set of processes being performed. A computer system may determine a trace signature for the log entry. This trace signature may track information related to the set of processes. The computer system may compute, using the trace signature, a log retention value for the log entry. This log retention value may be computed using weight factors for ones of the set of processes. The computer system may retain the log entry within a log file according to a retention period that corresponds to the log retention value.
