Data Disruption for Unauthorized Access Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security measures for electronic devices, such as microprocessors and non-volatile memory devices, are vulnerable to unwanted access as users can often circumvent security algorithms to use unauthorized accessories, necessitating a method to prevent or frustrate such access.
Innovation Solution
An apparatus and method involving a data disrupting unit, power source unit, and sensor unit that senses alert conditions to generate an action signal, disrupting or altering data stored in the host device to prevent unauthorized access, potentially by altering or corrupting the security key or algorithm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security algorithm with security key is used to limit access to data, then unauthorized access is restricted, but users can still circumvent the security by learning the security key
Solution Approach 1:
The patent applies preliminary anti-action by implementing a data disrupting unit that proactively corrupts security-sensitive data before an attacker can exploit it. When tampering is detected or anticipated, the system pre-emptively alters the security key or algorithm data, making it useless to attackers who may have already obtained copies. This transforms the security model from passive protection to active defense that anticipates and neutralizes threats before they can succeed.
Solution Approach 2:
The patent converts the potential harm of data access into a benefit by using the act of tampering detection itself to trigger data disruption. When the sensor unit detects unauthorized access attempts or environmental changes indicating tampering, this harmful event becomes the trigger that activates the data disrupting unit. The system transforms the attacker's harmful action into the beneficial activation of security countermeasures, ensuring that any attempt to breach security directly causes the security data to be corrupted.
2Adaptability or versatility
If security data is stored in the host device, then access control is enabled, but the security data becomes vulnerable to extraction and analysis attacks
Solution Approach 1:
The patent applies preliminary action by continuously monitoring environmental conditions and access patterns before actual data extraction attempts can succeed. The sensor unit proactively detects signs of tampering such as physical manipulation, temperature changes, or unauthorized access attempts before attackers can successfully extract the security data. This early detection allows the system to trigger data disruption before the harmful extraction occurs, making the security data unreachable even if attackers have physical access.
Solution Approach 2:
The patent introduces an intermediary layer between the security data and potential attackers through the sensor unit and data disrupting unit. Rather than directly protecting the stored security key, the system uses environmental sensors as intermediaries to detect tampering conditions and triggers a disruptive intermediary action that corrupts the data. This intermediary mechanism adds complexity to attack vectors, as attackers must not only bypass the security algorithm but also evade the environmental monitoring and trigger detection systems.
3Reliability
If firmware or software security measures are implemented, then manufacturer control over accessories is maintained, but users lose the ability to use unauthorized accessories
Solution Approach 1:
The patent applies dynamics by making the security protection adaptive rather than static. The security system continuously monitors environmental conditions and adjusts its protective state based on detected threats. During normal operation with authorized accessories, the system maintains standard functionality. When tampering is detected through sensor units monitoring physical or environmental changes, the system dynamically transitions to a protective state that disrupts data access. This dynamic approach allows legitimate user flexibility while automatically enforcing manufacturer control when threats are present.
