Output validation refers to the process of validating the output of a process before it is sent to some recepient. For example, if you search your output for credit card numbers and replace them with asterisks (*), you have validated the output before sending it. You might also validate the output for common attacks, such as XSS and SQL Injection before sending it.

NOTE: See HTML Entity Encoding which is a sort of output validation.
