Benefits of technology

The patent text describes a system and method for detecting manipulations to photographs, which can be used in various applications such as forensics, security, and advertising. The invention uses image analysis to compare attributes of an image with a database of reference signatures to determine if the image has been modified. The technical effect of the invention is to provide a reliable tool for detecting and objecting to manipulations to photographs, which can be used to protect against fraud and ensure trust in photographic images.

Problems solved by technology

The resulting undermining of trust in photographic images impacts law enforcement, national security, the media, advertising, e-commerce, and more.

Embodiment Construction

[0010]The invention can be implemented in numerous ways, including as a process; an apparatus; a system; a composition of matter; a computer program product embodied on a computer readable storage medium; and / or a processor, such as a processor configured to execute instructions stored on and / or provided by a memory coupled to the processor. In this specification, these implementations, or any other form that the invention may take, may be referred to as techniques. In general, the order of the steps of disclosed processes may be altered within the scope of the invention. Unless stated otherwise, a component such as a processor or a memory described as being configured to perform a task may be implemented as a general component that is temporarily configured to perform the task at a given time or a specific component that is manufactured to perform the task. As used herein, the term ‘processor’ refers to one or more devices, circuits, and / or processing cores configured to process da...

Abstract

Evaluating an image is disclosed. A plurality of attributes of the image is analyzed. A determination is made that a portion of the attributes of the image imperfectly matches a reference attribute signature corresponding to a device. It is distinguished whether the imperfect match likely corresponds to a modification of the image.

Description

CROSS REFERENCE TO OTHER APPLICATIONS[0001]This application is a continuation of co-pending U.S. patent application Ser. No. 13 / 782,032, entitled PHOTO FORENSICS USING IMAGE SIGNATURES filed Mar. 1, 2013 which is incorporated herein by reference for all purposes, which claims priority to U.S. Provisional Patent Application No. 61 / 641,636 entitled PHOTO FORENSICS FROM JPEG SIGNATURES filed May 2, 2012 which is incorporated herein by reference for all purposes.BACKGROUND OF THE INVENTION[0002]Recent advances in computational photography, computer vision, and computer graphics allow for the creation of visually compelling photographic fake images. The resulting undermining of trust in photographic images impacts law enforcement, national security, the media, advertising, e-commerce, and more. The field of photo forensics has emerged to help determine whether a photographic image has been manipulated. Often, techniques in photo forensics operate on the assumption that most forms of tamp...
