Double Answer check

for example, i need to catch information about some proyect in a request, and any of this information are numeric inforamation, for example: id, values of proyect, etc.

we need to provide a case to check that this data are correct, and normally the requests uses a second question to valid this data

for example:
please enter your ID
--> 10011110
please repeat your ID
-->10001110
Then as the answer are diferent, the system say: please valid the data, this are diferent.
