The owner module (xt_owner) matches the owner of the socket

# iptables -m owner --help
iptables v1.4.4
[...]
owner match options:
[!] --uid-owner userid[-userid]      Match local UID
[!] --gid-owner groupid[-groupid]    Match local GID
[!] --socket-exists                  Match if socket exists


man iptables for more details ;)
