Barcode Encryption for Logistics Data Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In logistics distribution, customer information such as addresses and contact details on delivery orders is vulnerable to exposure in public areas, compromising security.
Innovation Solution
Converting address information into longitude and latitude data, encrypting it with telephone numbers using MD5, and generating barcodes to securely transmit and decode user information, ensuring confidentiality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If practical information of the customer is directly printed on the delivery order, then the delivery personnel can acquire the customer information directly by naked eyes, but the customer information is at risk of being revealed because of the circulation of the delivery order in public area
Solution Approach 1:
The patent uses barcodes as visual copies that encode customer information without exposing the actual sensitive data. Instead of printing readable address and phone number directly on the delivery order, the system generates barcodes containing encrypted versions of this information. Delivery personnel can scan these barcodes to access the information through a terminal device, while the physical delivery order remains visually secure during circulation in public areas.
2Object-affected harmful factors
If customer information is encrypted and stored in barcodes, then the confidentiality of the delivery order is improved, but the complexity of the system increases due to encryption and decoding processes
Solution Approach 1:
The patent applies parameter changes by transforming customer information into different data formats through encryption algorithms (such as MD5). The original plaintext information is converted into encrypted strings that are then encoded into barcode formats. This parameter transformation ensures that even if the barcode is visually inspected, the underlying customer information remains protected, while the system complexity is managed through standardized encryption protocols.
3Ease of operation
If address information is converted into longitude and latitude data, then the portability of the information is maintained, but the difficulty of detecting and measuring the original address information increases
Solution Approach 1:
The patent introduces longitude and latitude coordinates as an intermediary representation of customer address information. Instead of storing or displaying the original address text directly, the system converts addresses into geographic coordinates that are then encrypted and encoded into barcodes. This intermediary transformation maintains the essential location information needed for delivery while significantly increasing the difficulty of recovering the original address from the encoded data.

AI summary
Disclosed in the present invention are a method and apparatus for use in information processing. One embodiment of the method comprises acquiring address information and a telephone number of a user; converting the address information of the user into longitude and latitude data; encrypting the longitude and latitude data and the telephone number so as to produce a ciphertext; generating a bar code according to the ciphertext such that a terminal parses the address information and telephone number of the user by the bar code. Said embodiment may conceal personal information of the user so as to prevent the disclosure of the personal information of the user.
