Information Carrier State Verification for Secure Content Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sales items lack effective protection against unauthorized access and retrieval of electronically provided content, such as streaming media, which can lead to unauthorized use or access without proper authorization.
Innovation Solution
Incorporating an information carrier that undergoes an irreversible change of state upon damage, allowing a dynamic address with security features to be generated, which depends on the sales item state, enabling secure verification of authorization and preventing unauthorized access by providing different access levels based on the item's state, such as preview or full access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an information carrier is used to provide access to electronically provided content, then ease of access and operation is improved, but vulnerability to unauthorized access and retrieval increases
Solution Approach 1:
The patent changes the state parameter of the information carrier from a static condition to a dynamic condition that evolves through defined states (unopened, opened, used). This state-based parameter change enables the system to differentiate between authorized and unauthorized access attempts, allowing easy operation for legitimate users while preventing unauthorized access through state verification.
Solution Approach 2:
The information carrier acts as an intermediary between the user and the electronically provided content. It mediates access by controlling the generation of dynamic addresses that lead to content retrieval. The carrier's state determines whether a valid dynamic address can be generated, thus controlling access without requiring direct authentication mechanisms that would complicate operation.
2Device complexity
If a static access method is used for electronically provided content, then simplicity is maintained, but security against unauthorized retrieval is insufficient
Solution Approach 1:
The patent introduces dynamics into the access method by generating dynamic addresses that are valid only for specific time periods and states of the information carrier. Instead of a static access code that remains constant, the system uses dynamic addresses that change based on the carrier's state (unopened/opened/used), providing enhanced security while maintaining relatively simple operation through automatic state detection.
Solution Approach 2:
The system performs preliminary actions by pre-defining the state transitions and security features that will be applied to the information carrier. The dynamic address generation mechanism is prepared in advance with embedded security features, so that when access is attempted, the appropriate security measures are automatically applied based on the carrier's current state, without requiring complex real-time decision-making.
3Ease of operation
If the information carrier allows multiple access attempts, then user convenience is improved, but the risk of unauthorized use increases
Solution Approach 1:
The patent segments the access process into distinct state transitions: unopened state, opened state, and used state. Each state represents a discrete segment of the access lifecycle with specific permissions and security requirements. This segmentation allows multiple legitimate access attempts within the unopened and opened states while preventing unauthorized use in the used state, as each transition is clearly defined and verifiable.
Solution Approach 2:
The system implements feedback by continuously monitoring the state of the information carrier and adjusting access permissions accordingly. When the carrier transitions to the used state, the system provides feedback by invalidating further dynamic address generation, thereby preventing additional unauthorized access attempts. This feedback mechanism ensures that convenience is maintained for authorized users while blocking unauthorized use after the appropriate state transition.
Data Source
AI summary
A sales item which has an information carrier which can be read by a reader, on said information carrier various sales item states are stored. Expediently, damage to the information carrier causes an irreversible change of state of the sales item. Advantageously, a reliable protection against unauthorized retrieval of the contents is created. Further, a method for verifying an authorization to retrieve an electronically provided content by reading an information carrier of a sales item.
