when A and B have the same age, after protocol it should be known that two people in the group have the same age. and it shouldn't be known that A and B have the same age, because this makes A know how old is B, and vice versa...(No one shall discover which numbers are equal.)

@ PaĆ­lo Ebermann, Actaully i am new to cryptography, but for example it can be used to determine if three persons are from the same age or not, without revealing any information about their ages.

they communicate sequentially, and the last person may tell the others the result .... but i am also interested in protocols where everyone of them can communicate with everyone else ...

actually, there is no fourth person to compare the values(trusted center), every thing should be done only between the three persons.. and therefore depending in your comment, if two numbers are equal then two of the persons will know which numbers are equal.

comment Non-Interactive Zero-Knowledge-Proof for discret Logarithm?
sorry, i mean the prover has the value of the discrete logarithm $x$, and he want to convenes the verifier that he knows the value of $x$ without giving the verifier this value ..
