Abstract: Systems and methods are disclosed for trusted imaging. In some examples, a trusted imaging device can emit a patterned light onto a real-world scene while an image sensor (e.g. photo or video) generates data representative of the real-world scene. The data can be processed to attempt to recover a pattern of the patterned light from the data. Whether, or to what extent, the pattern can be recovered can be determinative of a trustworthiness of the data from the image sensor. In further examples, the image data can be encrypted, as well as the imaging device output. In still further examples, a depth map of the image data can also be used to determine the trustworthiness of the image data.
