Abstract: In some embodiments, a method of verifying images includes receiving, at a server, a request from a mobile device to sign a device public key of the mobile device; in response to the request from the mobile device, signing, at the server, the device public key with a server private key so as to generate a signed device public key and returning the signed device public key to the mobile device; generating, at the mobile device, data for verification; signing, at the mobile device, the data with a device private key of the mobile device; and storing, at the mobile device, the signed data, the device public key of the mobile device, and the signed device public key of the mobile device as a data token. Numerous other aspects are provided.

Abstract: A method for removing satellite trails from images includes the following: obtaining an initial image having stars, locating stars in the image, removing the located stars from the initial image to form a star-removed image, locating the satellite trail in the star-removed image, determining brightness information for the satellite trail in the initial image including trail wobble information, creating a satellite-trail-containing image with only satellite trail brightness information based on the determined brightness information, and subtracting the satellite-trail-containing image from the initial image to remove the satellite trail so as to form a satellite-trail-removed image. Systems for removing satellite trails from images are also provided, as are other aspects.
