Patent ID: 8639062

Claim:
A computer-implemented method of ensuring integrity of a plurality of images in a document archive, the method comprising: receiving, by an image management platform, a captured image of a document, wherein the image comprises image characteristics; analyzing, by an image analysis module functionally connected to the image management platform, the captured image of the document to determine the image characteristics associated with the image and storing the captured image of the document as an image file; storing, by the image management platform, the one or more image characteristics associated with the image in an index, separate from the image file; receiving, at the image management platform and from an application, a request to access the image file associated with the captured image of the document; comparing, by the image management platform and in response to the request by the application to access the image file associated with the captured image of a document, the image characteristics stored in the index with image characteristics embedded in the image file to verify the integrity of the image file prior to granting the request by the application to access the image file; in response to the image management platform determining that the image characteristics stored in the index match the image characteristics embedded in the image file, sending the image to the application that requested access to the image file; analyzing, by the application, the image file to determine the image characteristics associated with the image; extracting, by the application, embedded characteristics data from the image file; comparing, by the application the image characteristics determined by the application with the characteristics data extracted from the image file by the application; and in response to determining that the image characteristics determined by the application match the characteristics data extracted from the image file by the application, verifying, by the application, the integrity of the image file.
