A symbol of authority as in Isa. 22: 22 and as when Peter was given the keys of the kingdom of heaven (Matt. 16: 18) as the reward for his stumbling confession of the Messiahship of Jesus. The privileges would seem to be that of admitting persons into the Kingdom; certainly at Pentecost (Acts 2: 41) Peter admitted many into the Church in response to faith. Peter's authority is further explained as that of binding and loosing, which was a rabbinic term for forbidding and allowing, i.e. interpreting questions of right and wrong; a privilege extended to others, such as Paul.
