Stateless Data Obfuscation via Character Pair Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data obfuscation methods, such as encryption, are computationally heavy and require complex key management infrastructures, making them unsuitable for lightweight and efficient data protection in distributed computing systems.
Innovation Solution
A stateless data obfuscation method that produces a patternless output, allowing intended recipients to recover the original data with low computational costs, without requiring encryption or cryptographic keys. This method uses a dictionary-based mapping of data field values to character pairs and includes a recovery method that can be delivered separately or integrated into a larger script.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption is used to obfuscate data, then data security is improved, but computational complexity and key management requirements increase
Solution Approach 1:
The patent extracts the essential obfuscation function from complex encryption systems, removing the need for key management infrastructure while retaining data security. The solution uses a simple mapping mechanism that eliminates cryptographic keys, protocols, and associated management complexity.
Solution Approach 2:
The patent employs disposable, single-use mapping relationships between data fields and character pairs. Each obfuscation instance uses a unique mapping that doesn't require persistent key storage or management, effectively using cheap, temporary obfuscation mechanisms instead of expensive, persistent cryptographic systems.
2Reliability
If encryption is used to obfuscate data, then data security is improved, but computational overhead increases
Solution Approach 1:
The patent replaces the mechanical/computational system of encryption with a simple character substitution mechanism. Instead of performing complex cryptographic operations that consume significant computational energy, the system uses direct mapping and replacement of data field values with character pairs, dramatically reducing computational overhead.
Solution Approach 2:
The patent changes the fundamental parameter of obfuscation from cryptographic transformation to simple character mapping. This parameter change transforms the computational complexity from high (encryption/decryption operations) to low (character substitution), while still achieving the goal of data obfuscation and security.
3Productivity
If simple obfuscation is used, then computational cost is reduced, but pattern recognition becomes easier
Solution Approach 1:
The patent applies different character pairs to different data field values, creating local variety in the obfuscation pattern. Each unique data field value maps to a unique character pair, ensuring that the obfuscated output has no discernible patterns while the processing remains efficient through the use of simple lookup tables.
Solution Approach 2:
The patent creates an asymmetric relationship between the obfuscation process (simple forward mapping) and the deobfuscation process (requires the mapping key). The forward direction uses simple character substitution with no pattern, while the reverse direction requires the mapping relationship, creating asymmetric difficulty that protects against pattern recognition.
Data Source
AI summary
Systems and methods for obfuscating data. The technology herein can be used to produce an obfuscated output that exhibits no easily discernible pattern, making difficult to identify or to filter using regular expressions, signature matching or other pattern matching. The output nevertheless can be reversed and the original data recovered by an intended recipient with a relatively low-cost of processing, making it suitable for low-powered devices. The obfuscation is stateless and does not require encryption.
