Based on the study of data changes capture strategies and technologies,and considering to the characteristics of the directory service,this paper proposed a method on the basis of homomorphic hash for LDAP directory's data changes capture.It described the method's overall architecture and implementations.The essence of the method was a kind of special shadow table method which combined homomorphic hash function with main memory database technology.According to the homomorphism of the homomorphic hashing algorithm,this method could have quick access to the change data of directory service in the case of low data change rate.Performance analysis makes the feasibility and efficiency of this method verified.
