Environment-Matched Multimedia Display for Faster Private Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing diversity of multimedia data sharing methods, particularly through devices like mobile terminals, raises significant privacy concerns as audio and video data can be captured and shared anywhere, leading to uncontrolled dissemination and reduced security.
Innovation Solution
An information processing method that compares environment expressions of target data with the current scenario to determine if it should be displayed, allowing data to be shown only in specific environments, thus enhancing privacy and security without the need for additional encryption resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption methods are used to protect multimedia data, then data security is improved, but resource consumption increases and data access speed decreases
Solution Approach 1:
The patent extracts the environment expression matching function from traditional encryption systems. Instead of using cryptographic algorithms to control data access, the system extracts environmental context (location, time, device information) and compares it with pre-stored environment expressions associated with the multimedia data. This eliminates the need for encryption/decryption operations while maintaining security control.
Solution Approach 2:
The patent replaces the mechanical encryption system with an environmental context-based access control mechanism. Rather than relying on cryptographic keys and algorithms, the system uses environmental parameter matching (location, time, device identity) to determine whether data should be displayed. This substitution eliminates computational overhead of encryption while achieving the same security objective.
2Reliability
If encryption methods are used to protect multimedia data, then data security is improved, but data access speed decreases
Solution Approach 1:
The patent removes the encryption/decryption process from the data access pathway. When a user requests multimedia data, the system directly retrieves the data and simultaneously checks whether the current environmental context matches the stored environment expressions. This parallel processing eliminates the sequential bottleneck of encryption verification, significantly improving access speed while maintaining security control.
Solution Approach 2:
The system performs preliminary actions by pre-storing environment expressions (location, time, device information) associated with each multimedia data item during data creation or upload. When data access is requested, the system only needs to compare current environmental parameters against these pre-stored expressions, rather than performing time-consuming encryption verification in real-time.
3Reliability
If environment expression comparison is used to control data display, then privacy protection is improved, but system complexity increases
Solution Approach 1:
The patent segments the environment expression into discrete, independently comparable parameters such as location information, time information, and device information. Each parameter can be extracted, stored, and compared separately. This segmentation simplifies the overall system architecture by breaking down the complex task of environment matching into manageable modular operations, making the system easier to implement and maintain.

AI summary
An information processing method includes obtaining target data, in a first scenario, outputting the target data in a first method, and in a second scenario, outputting the target data in a second method. The first scenario is different from the second scenario. Environment expression corresponding to the first scenario is consistent with environment expression corresponding to the target data. Environment expression corresponding to the second scenario is inconsistent with the environment expression corresponding to the target data.
