Abstract：This paper proposes a new photo security synchronization program based on improved SyncML. In order to ensure the efficiency of photo synchronization、save the network traffic and ensure the safety of photo transfer or cloud storage, New photo security synchronization program based on improved SyncML extracts the fingerprints for photos which may need to be synchronized at first. Then, the new program determines the photos that need to synchronize by adding a interactive between the mobile device side and server side. Next, the new program encrypts photos that need to synchronize, and finally complete the synchronization process. The new program uses a modified SHA-1 algorithm to extract fingerprints of photos, this modified algorithm improves fingerprint extraction speed Experimental results show that the new program can significantly improve the speed of photo sync process.
