Digital Object Identifier Proximity Communication via Camera Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for proximity bidirectional communication in offline scenarios require special communication modules like Bluetooth or NFC, leading to high costs.
Innovation Solution
Implementing a method and apparatus for information exchange using digital object identifiers (DOIs) that allow end-user devices to scan and identify each other using front-facing cameras, eliminating the need for special communication modules by generating and displaying service DOIs that include identity and service information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth or NFC communication modules are used for proximity bidirectional communication, then communication functionality is achieved, but device cost increases
Solution Approach 1:
The patent applies universality by making the camera module serve multiple functions: its primary function of capturing images is enhanced to also scan DOIs and establish communication connections. This allows the device to achieve proximity bidirectional communication without requiring dedicated Bluetooth or NFC modules, thereby reducing device cost while maintaining communication functionality
Solution Approach 2:
The patent uses copying by representing device identity and communication information in the form of a DOI (digital object identifier) that can be captured by the camera. Instead of requiring direct wireless communication hardware, the system creates a visual copy of communication data that can be scanned and processed, enabling communication through the existing camera infrastructure
2Reliability
If Bluetooth communication is used for proximity bidirectional communication, then communication is established, but communication steps become complex
Solution Approach 1:
The patent replaces the mechanical/wireless system of Bluetooth pairing with an optical system. Instead of requiring users to navigate through Bluetooth pairing menus and establish wireless connections, the system uses optical scanning where the camera captures a DOI and automatically processes the communication establishment, significantly simplifying the user操作流程
Solution Approach 2:
The patent applies preliminary action by pre-generating DOIs that contain all necessary communication and identification information. This allows the communication establishment to occur in a single scanning action rather than requiring multiple steps of device discovery, pairing, and connection establishment that characterize Bluetooth communication

AI summary
This specification techniques for sharing service and identity information between devices. One example method include acquiring, by a first device, a digital object identifier (DOI) of a second device, the DOI including identity information associated with the second device; generating, by the first device, a service DOI based on the identity information from the DOI of the second device, the service DOI including the identity information of the second device and service information; and displaying, by the first device, the service DOI on a display of the first device, wherein the displayed service DOI is configured to cause the second device to perform service processing when the displayed service DOI is acquired by the second device, and wherein the service processing is based at least in part on the identity information and the service information included in the service DOI.
