Deidetifying the dates

[Smitha9]

Hi,
I want to decidentify the dates which is mm/dd/yyyy format.
Example:
07/29/1980
09/27/2008
06/23/2003
01/25/2006

And also want to retrieve the original dates when needed in future.

Thanks in advance.

What do you mean by "de-indentify"? Setting the dates to missing will remove any means of identification for example. Keeping the original dataset will retain the data for future use.

Hardly possible to understand what you want. Please explain "Deidetifying" / "decidentify", show the expected result and explain what you want to achieve.
