Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current product labeling and security packaging technologies face challenges in providing robust authentication and anti-counterfeiting solutions, as they often rely on single data channels that are sensitive to errors and may not adapt well to different imaging devices or conditions, leading to reduced accuracy and increased vulnerability to counterfeiting.
Innovation Solution
The implementation of a printed information device that utilizes multiple channels with distinct data reading strategies, including 2 hue and 6 hue data reading strategies, which allow for error tolerance and robustness by encoding data in regions of interest with independent channels, enabling accurate authentication even with imperfect readings and varying imaging capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single data channel is used for authentication, then device complexity is reduced, but measurement precision and reliability deteriorate due to error sensitivity
Solution Approach 1:
The authentication system is segmented into multiple independent data channels (e.g., hue channel, saturation channel, brightness channel) within the color space. Each channel independently encodes authentication data, allowing the system to divide the authentication task across multiple pathways rather than relying on a single data channel, thereby improving precision without excessive complexity.
Solution Approach 2:
The patent transitions from single-dimensional authentication to multi-dimensional authentication by utilizing multiple channels in the color space (hue, saturation, brightness). This dimensional expansion allows data to be encoded across different color attributes, providing redundant authentication pathways that enhance measurement precision while maintaining manageable system complexity.
2Ease of operation
If single data channel is used for authentication, then ease of operation is improved, but reliability deteriorates due to vulnerability to counterfeiting
Solution Approach 1:
The authentication marker is segmented into multiple independent data channels within the color space, each capable of independently encoding and transmitting authentication data. This segmentation creates multiple authentication pathways that must all be successfully verified, significantly enhancing reliability against counterfeiting while maintaining ease of operation through automated multi-channel reading.
Solution Approach 2:
The system incorporates redundant authentication data across multiple color channels before the authentication process begins. This prior cushioning ensures that even if one channel is compromised or degraded during reading, the other channels provide backup authentication pathways, thereby enhancing reliability while keeping the operation simple for the end user.
3Measurement precision
If multiple channels with distinct data reading strategies are used, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The patent segments the authentication data into multiple independent channels based on color space attributes (hue, saturation, brightness). Each channel uses a distinct data reading strategy optimized for its specific color attribute, allowing precise reading of authentication data while organizing complexity into manageable, independent segments rather than a monolithic complex system.
Solution Approach 2:
The authentication marker serves multiple functions simultaneously by encoding data across multiple color channels. A single marker structure performs hue-based authentication, saturation-based authentication, and brightness-based authentication, reducing the need for separate physical markers or systems and thereby managing device complexity while improving measurement precision.
4Reliability
If multiple channels with distinct data reading strategies are used, then reliability is improved through error tolerance, but device complexity increases
Solution Approach 1:
The authentication system is divided into multiple independent data channels, each with its own error tolerance characteristics. By segmenting the authentication task across channels with different error tolerances, the system achieves enhanced overall reliability while organizing complexity into independent, manageable reading strategies for each channel.
Solution Approach 2:
Redundant authentication data is embedded across multiple color channels before the authentication process. This prior cushioning through redundancy ensures that the system can tolerate errors in individual channels while maintaining reliable authentication, managing the complexity of multiple reading strategies through pre-planned error compensation.

AI summary
A printed information device includes a region of interest in an image, and at least two channels assigned to the region of interest by different means of logical partitioning. The region of interest represents a physical area of the image. Each of the channels has a different error tolerance. Continuous and/or cyclic information is independently encoded in each of the at least two channels. The deterrent is configured to be read substantially simultaneously by at least two distinct reading strategies.
