Abstract

Real-world multimedia data is often composed of multiple modalities such as an image or a video with associated text (e.g., captions, user comments, etc.) and metadata. Such multimodal data packages are prone to manipulations, where a subset of these modalities can be altered to misrepresent or repurpose data packages, with possible malicious intent. It is therefore important to develop methods to assess or verify the integrity of these multimedia packages. Using computer vision and natural language processing methods to directly compare the image (or video) and the associated caption to verify the integrity of a media package is only possible for a limited set of objects and scenes. In this paper we present a novel deep-learning-based approach that uses a reference set of multimedia packages to assess the semantic integrity of multimedia packages containing images and captions. We construct a joint …
