Abstract: A method and a system for enabling multiple log record consumers to comply with regulations and requirements regarding privacy and handling of data are described. A determination, based on a log record format being of a first of the log record types, that a first field from a raw log record is to be tokenized based on a first tokenization strategy of multiple tokenization strategies in the first log record type, is performed. Each one of the tokenization strategies identifies a tokenization mechanism from tokenization mechanisms for generating a token from a raw value to enable compliance with a set of regulations and requirements regarding privacy and the handling of data. For a first raw value in the first field a first token is generated that is an anonymized representation of the first raw value using a tokenization mechanism identified by the first tokenization strategy in the log record type.
