BGP IP prefix hijacking

Hi All, I am planning to write a tool to detect real time BGP IP prefix hijacking. I am glad to know some of the open problems faced by providers/companies/community. I would like to know how the community is currently dealing and mitigating with such problems. It will be very helpful to know some of the adopted strategies by the community to detect bgp IP prefix hijacking and problems that are yet to be solved. Also I would like to know some of the very well industry standard open source tools used in the area of BGP which makes life easier. Regards, Nagarjun
