Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing M2M systems face challenges in protecting data from misuse, preventing personal information exposure, and concealing user behaviors from hackers.

Innovation Solution

A method and apparatus that involves generating and storing fake data of the same type as real data within a resource, allowing access-controlled users to see only the real data while others are presented with fake data, thereby masking data trends.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If real data is stored in M2M system, then data utility is improved, but data security deteriorates

Engineering Contradiction:

Improvedata utilityVSAvoiddata security

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent segments data storage by creating separate storage locations for real data and fake data within the M2M system. Real data is stored in a protected manner while fake data is stored separately, allowing the system to provide different data views to different users. This segmentation enables both data utility (real data accessible to authorized users) and data security (real data protected from unauthorized access).

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces fake data as an intermediary element that mediates between data utility and data security. Fake data serves as a decoy that protects real data by misleading unauthorized users. The system uses this intermediary to satisfy the contradiction by providing useful data to authorized users while protecting real data from unauthorized access through the presence of fake data.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If data is protected by access control, then data security is improved, but data accessibility deteriorates

Engineering Contradiction:

Improvedata securityVSAvoiddata accessibility

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent creates fake data copies that mimic the structure and format of real data. These copies are stored alongside or alongside real data and can be accessed by users who don't have authorization for the real data. This copying approach maintains data accessibility for legitimate users while protecting security by providing alternative data that appears authentic but is actually fake.

Inventive Principle:

Principle #26Copying

3Object-affected harmful factors

If fake data is mixed with real data, then data security is improved, but data quality deteriorates

Engineering Contradiction:

Improvedata securityVSAvoiddata quality

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent applies local quality by ensuring that fake data and real data maintain their distinct identities while coexisting in the same system. The fake data has specific characteristics that differentiate it from real data, allowing the system to maintain overall data quality. Authorized users can distinguish and access only real data, while the presence of fake data with different local characteristics enhances security without compromising the quality of real data.

Inventive Principle:

Principle #3Local quality

AI summary

The present disclosure relates to hiding data trends in a machine-to-machine (M2M) system. A method for operating a first device in a machine-to-machine (M2M) system may include: performing a registration procedure for a second device; receiving real data generated by the second device; obtaining fake data of an identical type as the real data; and storing the real data and the fake data in a same resource.
