Abstract
Private, personal, secret, or otherwise sensitive data is masked or redacted in response to receiving an event signal indicative of an occurrence, if any, of at least one of a number of defined events associated with the set of data. The data to mask is detected by matching it to one or more defined patterns and then validating it, in the case of the data being a financial account or credit card account number, by using a validation process, such as the Luhn algorithm. Among others, the defined event may be a transmission of the data between a host computer system and a terminal emulator, an entry of the data into a host screen, or an export of a set of host screen data to an external application by an end user computer system.
