            String sfzRight = StringUtils.right(cardId, 4);
            sfzRight = StringUtils.leftPad(sfzRight, StringUtils.length(cardId), "*");

            tmAddress = StringUtils.left(address, 6);
        } else {
            tmAddress = StringUtils.left(address, address.length() / 2);
        }
        tmAddress = StringUtils.rightPad(tmAddress, StringUtils.length(address), "*");

        if (-1 == index) {
            return email;
        } else {
            tmEmail = StringUtils.right(email, email.length() - index);
        }
        tmEmail = StringUtils.leftPad(tmEmail, StringUtils.length(email), "*");
        return tmEmail;
