Abstract: In order to ensure the integrity of massive data transmission under big data cloud storage，a massive
data transmission integrity control method based on attribute feature matching and association rules is proposed．
The high dimensional reorganization model of attribute features of massive data is constructed，and the feature
distribution of key information is obtained． The key information storage and distribution structure model of massive
data is designed，the key information feature mining and extraction of massive data is carried out by using
association rule method． The feature analysis and clustering processing of massive data are carried out by using
key information． And the key information storage nodes of massive data are designed by attribute feature matching
method． Using fuzzy subtraction clustering to store key information the storage node carries on the clustering
processing． In the massive data transmission，the data key information storage node transmission integrity degree
is used to realize the massive data transmission integrity control． The simulation results show that this method can
improve the efficiency of spatial utilization and the integrity of data transmission in cloud storage．
