Methods and systems for authentication of a physical document

A computerized method of authentication of a physical document, the method comprising:

• capturing, using an image capture device coupled to a mobile computing device, images of a physical document in a scene, during which the mobile computing device adjusts one or more operational parameters of the image capture device, resulting in a sequence of images captured using different capture settings;
• partitioning, by the mobile computing device, the sequence of images into one or more subsets of images, wherein each subset comprises images with a similar alignment of the physical document and captured using the same capture settings;
• processing, by the mobile computing device, the subsets of images to identify a region of interest in each image, the region of interest corresponding to one or more visual features of the physical document;
• generating, by the mobile computing device, a representation of the identified region of interest using the processed images;
• generating, by the mobile computing device, an authentication score for the document using the representation of the identified region of interest;
• and
• determining, by the mobile computing device, whether the physical document is authentic based upon the authentication score.
