Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless neighborhood aware networks lack efficient methods for secure and private service identification, leading to potential third-party monitoring of service usage and lack of privacy for service providers and users.
Innovation Solution
The implementation of a method and apparatus for generating and transmitting private service identifiers in wireless neighborhood aware networks using a hash value based on a service name and timing information, which enhances privacy by encrypting service IDs and changing their values frequently, thereby reducing the likelihood of undesired monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional service identifiers are used in wireless networks, then service identification is simple and straightforward, but service usage can be monitored by third parties and user privacy is compromised
Solution Approach 1:
The patent applies parameter changes by transforming the service identifier from a static, human-readable format to a dynamic, hashed format that changes over time. The service identifier is converted using a hash function that incorporates timing parameters, causing the identifier to expire and change periodically. This resolves the contradiction by enhancing security through parameter transformation while managing complexity through systematic expiration and renewal mechanisms.
Solution Approach 2:
The patent implements dynamics by making service identifiers time-dependent and transient rather than static. The identifiers have expiration times and are periodically renewed, creating a dynamic identification system. This resolves the security-privacy contradiction by ensuring that even if identifiers are intercepted, they become invalid after expiration, while the complexity is managed through automated renewal processes.
2Loss of information
If service identifiers are changed frequently to enhance privacy, then third-party monitoring is reduced, but the complexity of tracking and managing service identifiers increases
Solution Approach 1:
The patent applies periodic action by implementing time-based expiration and renewal of service identifiers. Identifiers are valid only for specific time periods and automatically expire, requiring periodic renewal. This resolves the privacy-complexity contradiction by systematically limiting identifier validity periods to prevent long-term monitoring, while the renewal process manages complexity through structured periodic updates rather than ad hoc changes.
Solution Approach 2:
The patent implements preliminary action by pre-establishing expiration times and renewal mechanisms for service identifiers. The system proactively manages identifier lifecycles by setting expiration parameters in advance and automatically initiating renewal processes before identifiers become invalid. This resolves the contradiction by preventing privacy breaches through pre-planned identifier rotation while managing complexity through automated preliminary actions rather than reactive management.
3Reliability
If hashed service identifiers with timing information are used, then service privacy is protected and monitoring is reduced, but the process of generating and managing identifiers becomes more complex
Solution Approach 1:
The patent applies mechanics substitution by replacing traditional mechanical identifier assignment methods with cryptographic hash functions. Instead of manually assigning or sequentially generating identifiers, the system uses hash functions that take service information and timing parameters as input to generate identifiers automatically. This resolves the privacy-ease contradiction by providing strong privacy protection through cryptographic transformations while simplifying generation through automated hash-based processes that eliminate manual intervention.
Solution Approach 2:
The patent implements self-service by enabling the system to automatically generate, manage, and renew service identifiers without external intervention. The hash-based generation process uses embedded timing information and service parameters to self-generate identifiers, and the system automatically handles expiration and renewal. This resolves the contradiction by ensuring privacy through automated cryptographic processes while improving ease of manufacture by eliminating complex manual management procedures.
