In order to solve the problem of information privacy leakage in storage and transportation logistics databases and improve the storage security of database information privacy, a chaotic mapping based encryption storage method for storage and transportation logistics database information privacy is proposed. Designed a distributed storage architecture for storage and transportation logistics database information, segmented and integrated the information of the storage and transportation logistics database, and encrypted the privacy of the database information using chaotic mapping; Implement secure storage of database information through access control. Through experimental verification, it has been proven that this method can reduce the workload of changing permissions, with an average encryption and decryption time of less than 10 ms. It can effectively improve the efficiency of encrypted storage and enhance the security of database information privacy storage.
