Users’ operating document behaviors in the cloud environment were built by collecting ,arranging and analy‐zing the records .And the potential risk coefficient of documentation operation was obtained by Bayesian network structure learning algorithm .Experimental results showed that the Bayesian network can predict risks of user opera‐tion documentations effectively and provides an early‐warning mechanism for security of documents in the cloud envi‐ronment ,which improved security of documents .
