The TrustedCamApp project builds on the results of the BMBF-funded research project TrustedCam and aims to enable tamper-free video recordings on mobile devices. While TrustedCam developed technologies to secure video recordings in industrial and governmental contexts, TrustedCamApp transfers these to the civilian domain, specifically for use on smartphones.
With the increasing prevalence of mobile phones with video capabilities, especially in crisis and conflict areas, the risk of misinformation through manipulated videos also rises. TrustedCamApp offers an open-source solution that establishes a secure connection between the camera system, recording application, and security application. The project implements an innovative registration method that prevents manipulations between the image sensor and storage.
For verification, GPS data and system information are used to check the identity of the device. Additionally, blockchain technology is employed to ensure the integrity of the captured information. A dynamic blinking pattern with an embedded QR code serves as an additional protection mechanism.
This technology lays the foundation for various application areas where the verification of digital content is crucial, providing the basis for future developments in secure and tamper-proof multimedia recordings.
