Design And Implementation Of Express Privacy Protection System Based On Identity Encryption

With the development of computer technology,people rely more and more on convenient online shopping,which promotes the development of China's logistics industry.With the increase of the number of express users,the incidents of leakage of users' privacy information in express face sheet emerge in endlessly,which do harm to the property and even personal safety of express users.Therefore,in recent years,the protection of express private information has become the focus of logistics industry research.In order to solve the problem of privacy leakage of express delivery face sheet,based on the analysis of the existing privacy protection scheme,according to the actual needs of the system,an identity based encryption scheme for express delivery privacy protection is designed: IBE encryption mechanism is combined with hierarchical encryption method,and quick response code is used to transfer encrypted information.The sender's identity information is used as the public key,and the corresponding private key is generated through IBE mechanism.The courier delivery is carried in the order of province city district county specific address.Therefore,the scheme uses hierarchical encryption to encrypt the courier privacy information,and different levels of public keys to encrypt the next level address information,The sender's public key encrypts the specific address information and the recipient's privacy information.After different levels of transfer stations scan the QR code on the express delivery and decrypt it with their own private key,they can only get the corresponding next level address.Until the dispatcher finally delivers the delivery,they log in to the system to scan the QR code and decrypt it,and then they can see the recipient's specific address,name,telephone number and other private information,In this way,the privacy information security of the recipient and the sender is ensured in the process of express delivery.On the basis of this scheme,the express privacy protection system is implemented,and a new type of privacy express business process is designed.The system meets the daily needs of express delivery personnel,and the encryption and decryption time of express privacy information is kept within 0.5-1 second,and the decryption success rate is more than99%,which achieves the expected effect of the system.
