The communication latency presents a major challenge to achieving high responsiveness for Internet-based cooperative editing systems. In this paper, we propose conflict control locking (post-locking) schemes for conflict resolution in real-time object-based cooperative graphics editors. With these schemes, no locking request is needed before applying an editing operation to an object; instead, a lock will automatically be generated by the system if a conflict occurs. Lock ownership assigning rules are devised for the schemes. With a specific post-locking approach, algorithms and implementation techniques, such as, lock synchronisation detection, voting, and group intention realisation, are discussed in detail.
