Robert Galambos correctly noted that this isn't easy. The problem with most data masking approaches is that they require a lookaside table (a cross-reference to the "real" data), or else they break the relationships between tables (SSN 123-45-6789 in table A doesn't get randomized to the same value in table B, so joins et al. don't work). Our product, Voltage SecureData, uses a mode of AES encryption that preserves the data format -- so an SSN that gets encrypted comes out looking like an SSN, an address come out as a combination of letters and numbers, as it was entered, etc. This makes it ideal for masking: by *encrypting* the data, you avoid the lookaside issue, with its attendant headaches (and security risks). The inter-table relationships are preserved. And if you should need to reverse the encryption to verify a result, you can do so. Voltage SecureData is multi-platform: z/OS, Windows, Linux, Solaris, AIX...you name it. ASCII/EBCDIC is handled automatically, so you can encrypt on one platform and decrypt on the other. If you'd like more info, drop me a line. And sorry for the ad -- but you did ask.
