Abstract: With the rapid development of e-commerce,the express industry is particularly hot.A large number of users habitually throw away the unprocessed express box after taking the express,at this time,a large number of users' plaintext privacy information on the express bill will face the risk of leakage.AES algorithm is a symmetric cipher algorithm,which has the characteristics of simple algorithm,fast encryption and decryption,high security and so on.It is an ideal algorithm for encrypting express industry users' plaintext information.QR code (fast response two-dimensional code) has the advantages of high security,fast reading speed,printing in small space,and reading from any direction.In order to ensure the efficiency of transportation,express delivery is based on the user's plaintext information.After the express delivery arrives at the destination,AES algorithm is used to encrypt the user's private plaintext information into ciphertext and generate the corresponding ciphertext two-dimensional code,which is printed and pasted on the express box.Python is used to realize the generation and recognition system of ciphertext two-dimensional code data,which not only protects the information security of users,but also reduces the phenomenon of pretending to get express delivery,which has high practicability.

Key words: AES, Express delivery, Information security, Python, QR Code
