There are likely to be many ways to do this.

Here's a quick way to mask the column.

CREATE VIEW Masked AS

SELECT REPLICATE('*',LEN(FirstName)) FirstName,

REPLICATE('*',LEN(LastName)) LastName,

'----/--/--' AS DOB

FROM Table

Or you could just leave those columns out of the view entirely. If you are truly concerned about the data you might consider a constant for both names instead of divulging the length of the actual data.
