Abstract
A system and method for providing obscured output from a data processing a system to allow analysis of the output without disclosing sensitive information. In response to an error condition, selected portions of the data being used in the data processing system are replaced by means of an irreversible algorithm to obscure the data, then the data processing is repeated with the obscured data to determine that the error still exists with the obscured data. If the error ceased to exist when one substitution technique is used, the process is repeated with a different technique in an attempt to find a substitution system which repeats the error while masking the data, allowing analysis of the files and correction of the error without divulging the information.
