Dynamic Barcode Generation for Digital Content Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for sharing and obtaining electronic content, such as e-books, are time-consuming, especially on mobile devices, requiring manual entry or search processes that can be cumbersome and inefficient, especially when sharing with multiple users.
Innovation Solution
Dynamic barcode generation on electronic devices that includes content identification, user information, and access rights, allowing other devices to capture and decode the barcode to obtain or share content efficiently, eliminating the need for manual entry and simplifying the process of content transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual entry or search methods are used to share e-book content, then content transfer can be achieved, but the process becomes time-consuming and cumbersome
Solution Approach 1:
The patent replaces manual mechanical input methods (typing, searching, copying URLs) with an optical scanning system. Users simply point a camera at a barcode displayed on a screen, and the system automatically captures, decodes, and processes the barcode information to transfer content, eliminating the need for manual entry operations.
Solution Approach 2:
The patent introduces a barcode as an intermediary carrier between the content source and the receiving device. Instead of directly transferring content through complex manual processes, the barcode serves as a simple intermediate that encodes all necessary information (content ID, user ID, access rights) and enables automatic system processing.
2Adaptability or versatility
If conventional sharing methods are used, then content can be transferred, but the process becomes complex when sharing with multiple users
Solution Approach 1:
The patent creates a universal barcode system that can handle multiple sharing scenarios (one-to-one, one-to-many, temporary sharing, permanent sharing) through a single standardized mechanism. The same barcode scanning process works for all user types and sharing purposes, eliminating the need for different procedures for different sharing situations.
Solution Approach 2:
The system automatically handles all sharing operations without requiring manual configuration for each user. When a barcode is scanned, the system autonomously decodes the information, identifies the user, checks access rights, and initiates content transfer automatically, eliminating the need for users to manually manage sharing complexity.
3Extent of automation
If barcodes include comprehensive information (content ID, user ID, access rights), then content transfer becomes efficient and automated, but barcode encoding complexity increases
Solution Approach 1:
The patent divides the barcode into distinct segments or zones that represent different types of information (content identifier portion, user identifier portion, access rights portion). This segmentation allows the complex information to be organized in a structured way that is easy to encode, decode, and process systematically.
Solution Approach 2:
The patent utilizes different barcode formats and encoding parameters to represent different types of information. By changing the encoding parameters (such as using different barcode types like QR codes, Data Matrix, or modified UPC codes) for different information segments, the system can efficiently pack complex data into a compact, scannable format.
Data Source
AI summary
A user can share digital content with another user or device using dynamically-generated barcodes. A user might request to share an electronic book (“e-book”), stored on a first device, with another user having a second device. The first device can generate a barcode that includes not only information about the identity of the e-book, but also information about the user or the first device, which can help to determine rights and/or access restrictions for the content. The second device can capture an image of the barcode generated on a display of the first device, and use information extracted from that image to attempt to obtain a copy of the e-book. Other types of barcodes can be generated based at least in part upon the context, such as where a user is attempting to locate a physical copy of a type of digital content in a retail location.
