Methods and systems for facilitating photo-based estimation are described. In an aspect, a server is configured to receive, via the communications module from a remote computing device, a signal comprising image data obtained by the remote computing device, the image data including metadata identifying an image capture location and a time of image capture; obtain verification data, the verification data comprising sensor data received from the remote computing device and identifying a location of the remote computing device at the time of image capture; and evaluate the image data based on the verification data to verify the authenticity of the image data by comparing the image capture location in the metadata to the location of the remote computing device at the time of image capture.
