16. A computer program product, comprising a non-transitory computer readable medium having program instructions embodied therewith, the program instructions executable by a processor to: receive a request to perform an operation using a mobile device, the operation requiring authentication; in response to receiving the request, initiate capturing an image of a document using the mobile device, the document depicting identifying information; extract the identifying information from the image of the document using the mobile device; validate the identifying information extracted from the image of the document against identifying information corresponding to an owner of the mobile device; determine an immutable identifier associated with the mobile device used to capture the image of the document; validate the immutable identifier associated with the mobile device used to capture the image of the document with an immutable identifier associated with the identifying information corresponding to the owner of the mobile device; and authenticate the operation in response to determining both: the identifying information extracted from the image of the document matches the identifying information corresponding to the owner of the mobile device; and the immutable identifier associated with the mobile device used to capture the image of the document matches the immutable identifier associated with the identifying information corresponding to the owner of the mobile device.
