Regular auditing of system logs allows for the detection of unauthorized changes or manipulations in the software.
Authentication and Access Control
Authentication and access control mechanisms are essential in preventing unauthorized access to software systems. These mechanisms ensure that only authorized individuals can make changes to the software. By implementing strong authentication protocols and access control policies, the chances of software tampering are significantly reduced.
Firmware Verification
Firmware verification involves the process of verifying the integrity of firmware installed on a system. By comparing the firmware’s checksum or digital signature against a trusted source, any unauthorized modifications can be detected. This technique ensures that the firmware has not been tampered with and guarantees the system’s security.
Network Tampering Detection
Network tampering detection focuses on identifying any unauthorized alterations or manipulations to network devices or data transmission. This type of tampering detection ensures the security of network communication and prevents unauthorized access. Some commonly used network tampering detection techniques include:
Network Activity Monitoring
Network activity monitoring involves the continuous surveillance of network traffic and communication. By analyzing network packets, any unusual or unauthorized activities can be identified. Monitoring network activity allows for the detection of suspicious behavior, such as unauthorized access attempts or data exfiltration.
Intrusion Detection Systems
Intrusion detection systems (IDS) are designed to identify and respond to any malicious activities or security policy violations on a network. These systems monitor network traffic and compare it against known patterns and signatures of attacks. When a deviation from normal behavior is detected, an alert is triggered, indicating potential tampering.
Protocol Monitoring
Protocol monitoring focuses on analyzing network protocols to detect any anomalies or unauthorized changes. By monitoring the protocol specifications and ensuring compliance, any modifications or manipulations can be identified. Protocol monitoring is crucial in detecting tampering attempts aimed at exploiting vulnerabilities or bypassing security mechanisms.
Video Tampering Detection
Video tampering detection is specifically targeted towards security cameras and surveillance systems. It enables the detection of any unauthorized modifications or alterations to video footage, ensuring the authenticity and reliability of the recorded data.

This technique allows for the quick detection of potential tampering, such as covering the camera or obstructing its view.
Image Comparison
Image comparison techniques involve analyzing consecutive frames of video footage to identify any discrepancies or differences. By comparing the frames pixel by pixel, any alterations or modifications can be detected. Image comparison is effective in detecting tampering attempts that involve modifying or replacing specific frames of video.
Scene Change Detection
Scene change detection focuses on identifying sudden changes in the camera’s field of view. For example, if an object is moved or removed from the scene, the algorithm detects this change and triggers an alert. Scene change detection is valuable in detecting tampering attempts that involve altering the environment captured by the camera.
Challenges in Tamper Detection
While tamper detection offers significant benefits, there are several challenges that need to be addressed to ensure its effectiveness. These challenges include:
False Positives and False Negatives
