1. A method for processing a digital image, comprising:
acquiring image data using an image sensor;
generating a compressed reference data from the acquired image data;
generating a hash of the compressed reference data using a hashing function;
signing the generated hash using an encryption function;
attaching the signed hash of the compressed reference data and the compressed reference data to a file of the acquired image data as metadata thereof;
transmitting the file of the acquired image data including the compressed reference data and the signed hash as metadata,
retrieving the compressed reference data and the signed hash from the metadata of the file of the acquired image and authenticating the retrieved compressed reference data based on the retrieved signed hash, and
verifying the authenticity of the acquired image data based on visual similarities between the acquired image data and the authenticated retrieved compressed reference data,
wherein the generating of the compressed reference data, the generating of the hash, and the signing of the hash are performed by the image sensor,
wherein the image sensor is part of a digital camera device.
