DESC:FIELD
The present disclosure generally relates to the field of detection and alerting devices. More particularly, the present disclosure relates to a device to detect tampering with a smart lock cable.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
The current methodology for epilepsy detection heavily relies on observing frequently occurring changes in brain function, particularly among women and children. Such anomalies can distort the three-dimensional understanding of brain activity, leading to epilepsy a condition characterized by abnormal brain activity, resulting in seizures, unusual behaviour, sensations, and sometimes loss of consciousness. However, these systems often overlook additional parameters that could enhance Anti-epileptic Drug (AED) prediction, thereby potentially reducing episodes of loss of consciousness. Many epilepsy detection systems incorporate ECG signal features for analysis, aiming to identify epilepsy through patterns of brain abnormality.
A crucial aspect of diagnosing a patient who has experienced a loss of consciousness is determining whether the episode was due to a seizure or syncope. Fortunately, with current AED therapies, up to 80% of patients with new-onset epilepsy achieve complete seizure control, and about 60% remain seizure-free even after discontinuing AEDs. Nonetheless, the limitations of existing detection systems include reliance on ECG signals, the necessity of cloud-based data processing, a narrow scope of application, limited data on patient episodes, and the challenge of choosing an initial AED that not only fully controls seizures but is also well-tolerated, safe over the long term, and user-friendly.
There is, therefore felt a need for a device to detect tampering with a smart lock cable that alleviates the aforementioned drawbacks.

Smart locks equipped with GPS and GPRS functionalities have emerged as cutting-edge solutions in the realm of security and access control. These locks offer real-time location tracking and event notifications, providing users with an unprecedented level of control and awareness over their secured spaces. However, the efficacy of these smart locks heavily depends on the robustness of their tamper detection mechanisms, especially concerning cable or shackle cutting attempts. Some models rely primarily on conductivity checks across the cable, a design choice that, while effective in principle, introduces vulnerabilities that can be exploited by sophisticated intruders.
The prominent challenge in the current generation of smart locks lies in the simplicity of their tamper detection systems, often limited to monitoring conductivity. This creates an avenue for attackers to manipulate the system by shorting the cable without triggering an alert. Moreover, users may be unaware of this potential vulnerability, leading to a false sense of security. The challenge is to bolster the tamper detection capabilities to a level where they remain reliable under various scenarios and thwart potential intruders who may exploit these weaknesses.
To address the challenges posed by the current vulnerabilities, a multifaceted approach to tamper detection is necessary. Incorporating resistance monitoring alongside conductivity checks is a pivotal step. This addition allows the system to detect nuanced changes in the cable's resistance, offering a more comprehensive and reliable tamper detection mechanism. Furthermore, the integration of multiple sensors, including temperature and vibration sensors, creates a layered defense against tampering. Dynamic resistance thresholds, randomized monitoring patterns, and a secure enclosure design collectively contribute to a more robust and adaptive tamper detection system. Regular security audits and firmware updates are crucial elements in ensuring that smart locks evolve with emerging security challenges, maintaining the integrity of the overall security architecture.

Figure 2A and Figure 2B illustrate a flowchart describing the method to detect tampering with a smart lock cable in accordance with an embodiment of the present disclosure. The order in which method 200 is described is not intended to be construed as a limitation, and any number of the described method steps may be combined in any order to implement method 200, or an alternative method. Furthermore, method 200 may be implemented by processing resource or computing device(s) through any suitable hardware, non-transitory machine-readable medium/instructions, or a combination thereof.

Figure 3A and Figure 3B illustrate the architecture of the device to detect tampering with a smart lock cable in accordance with an embodiment of the present disclosure. Figure 3A shows the front view of the lock 102 and Figure 3B shows the back view of the lock 102. Figure 3A shows the indicators of operating device 110 for indicating the status of the lock 102. The indicators include GPS for providing live positioning of the lock 102, GSM (network) for communication and transmitting data, and the Status of the lock which shows whether the tamper event occurs or not. Figure 3B shows that lock 102 has a pair of lock sections (holes) 102a and 102b for locking cable 104. The lock 102 checks the change in the resistance value to prevent tampering attempts by shorting the cable. The cable 104 with a connector end 104a and a terminal end 104b, wherein the connector end 104a is operatively coupled to the first lock section 102a and the terminal end 104b is operatively coupled to the second lock section 102b. The resistance data is transmitted in time intervals or continuously or in the event of detection of a tamper attempt (change of resistance) to the server 108 for processing. The device 100 provides real-time alerts in case of any tamper event, such as cutting the cable/ shackles. The device 100 measures the resistance (using Ohm law or Wheatstone bridge or any other method of measuring resistance) of cable 104 instead of simply checking for the conductivity of cable 104. The solution is applicable for any locking device/ seal that checks for conductivity across a cable to detect a tamper attempt.
In an operative configuration, the device 100 is a sophisticated tamper detection system engineered to enhance the security of smart lock cables. It integrates a lock 102, a cable 104, and a controller 106 that communicates with a server 108. The lock 102 consists of two sections: a first lock section 102a and a second lock section 102b, interconnected by a cable 104. The cable features a connector end 104a affixed to the first lock section and a terminal end 104b attached to the second lock section, forming the physical foundation for monitoring and detecting tampering attempts.
The controller 106 is the central component of the device, responsible for real-time monitoring and tamper detection. It employs a communication interface 114 to interact with the server 108 and monitors resistance data across the cable 104 to identify deviations that may indicate tampering. The controller's modular design includes a data repository 106a that stores lock-specific details, live positioning data, predefined resistance thresholds, and historical resistance records. This repository enables the controller to analyze real-time resistance data in comparison to historical and threshold values to detect anomalies accurately.
The data collector module 106b operates as the system’s real-time monitoring unit, recording resistance data and filtering out noise to ensure precision. The collected data is stored in the repository for further analysis. The transmitter module 106c facilitates communication by transmitting resistance data and tampering alerts to the server at predefined intervals or immediately when anomalies are detected. Meanwhile, the triggering module 106d evaluates the cable's electrical conductivity and identifies tampering events by analyzing deviations from the predefined resistance thresholds. When tampering is detected, it generates an alarm notification and communicates the alert to an operating device 110 for immediate action.
An additional layer of security is provided by a quick response (QR) code 112 embedded in the lock 102. This code encodes metadata, including lock details and a unique security token, enabling secure authentication and interaction with the server. Authorized users can scan the QR code to access detailed lock information and perform secure operations, thereby ensuring robust protection against unauthorized access or tampering.
The device operates seamlessly by continuously monitoring resistance data through the data collector module 106b and comparing real-time measurements with historical and threshold data stored in the repository. When significant deviations are detected, the triggering module 106d identifies the event as tampering, generates an alarm, and transmits the alert to the server and operating device via the transmitter module 106c. This device ensures prompt detection, alerting, and storage of tampering details for further analysis.
The device 100 represents a highly advanced and secure solution for tamper detection in smart lock systems. Its real-time monitoring, precise resistance analysis, modular architecture, and secure QR-based authentication provide robust protection against unauthorized access. With seamless communication to a server and comprehensive detection capabilities, the device ensures enhanced security for modern smart locks.
Advantageously, the device 100 offers significant advantages in ensuring the security and reliability of smart lock systems. By integrating real-time resistance monitoring with advanced analytics, it provides precise and immediate detection of tampering attempts, minimizing the risk of unauthorized access. Its modular architecture, comprising dedicated data collection, analysis, and communication modules, ensures efficient and accurate performance. The inclusion of a quick response (QR) code enhances usability by enabling secure authentication and interaction with the server, adding additional layer of protection. Furthermore, the system’s ability to store historical resistance data and predefined thresholds allows for adaptive learning, improving detection accuracy over time. Its real-time alerting and seamless communication with servers and operating devices ensure prompt responses to security breaches. Overall, the device’s combination of robust functionality, reliability, and secure interaction makes it an indispensable solution for safeguarding modern smart lock applications.
