摘要：In the real time, large amount of repository data contain sensitive information that must be protected against unauthorised access. Hiding the sensitive data is one method, but may not be a best method since it explicitly denotes that sensitive values are hidden. Another method is removing the primary identifier and then anonymizing the data so that the individual records are protected. This method also explicitly denotes that information is hidden. We have gone for a crypt method, where sensitive data is transformed. Perturbation is the method used, which was basically used to convert numbers. Here we have proposed a frame work which uses perturbation methods to convert string data.
