2019. Electromagnetic Vulnerabilities of LCD Projectors. Proceedings of the 6th Conference on the Engineering of Computer Based Systems. :1–6.
This paper presents for the first time a study on the security of information processed by video projectors. Examples of video recovery from the electromagnetic radiation of these equipment will be illustrated both in laboratory and real-field environment. It presents the results of the time parameters evaluation for the analyzed video signal that confirm the video standards specifications. There will also be illustrated the results of a vulnerability analysis based on the colors used to display the images but also the remote video recovery capabilities.
