Show HN: Tripwire: A new anti evil maid defense (github.com)

Tripwire has emerged as a new anti-evil maid defense system aimed at protecting devices from sophisticated physical attacks, known as "evil maid attacks," where an adversary gains access to a device left unattended. Unlike traditional monitoring solutions designed for burglaries, Tripwire utilizes a Raspberry Pi 5 combined with a camera and motion sensor to create a robust, tamper-evident security system. It operates by sharing secret keys with a user's mobile web client before deployment. If any motion is detected while the user is away, these secrets are deleted, ensuring that an attacker cannot erase evidence of their intrusion without detection. The significance of Tripwire lies in its potential to safeguard high-profile users like software developers, journalists, and legal professionals from technically adept threats. With built-in cryptographic measures, such as a public-private key pair for signing photos, users can verify the authenticity of captured evidence even if both the target device and the Raspberry Pi are compromised. This innovative approach enhances the security landscape for individuals concerned about privacy breaches and physical device security in ways that traditional off-the-shelf systems cannot, establishing a new standard for personalized monitoring in the AI/ML community.
