InVID at the IEEE Workshop on Information Forensics and Security 2017


The InVID Innovation Manager, Mr. Denis Teyssou from AFP, participated at the IEEE Workshop on Information Forensics and Security (WIFS) 2017 that took place in Rennes (France) at INRIA Bretagne Atlantique, and gave a talk on the state of the art in journalism about fake image and video detection.

During his presentation, Mr. Teyssou reported on a variety of currently existing guidelines, tools and approaches for forensics analysis, and discussed about investigative journalism and post-mortem analysis of events. Following, he showcased the application of some of these tools in real-life scenarios, to better illustrate their effectiveness in evaluating the originality and trustworthiness of a media item. Finally, Mr. Teyssou presented part of the work undertaken so far in the InVID project, focusing on the developed InVID Verification Plugin (freely available at:

The functionality of several analysis components of this tool, such as the ones for video fragmentation and reverse keyframe search, advanced Twitter search, detailed inspection of images using a digital magnifying glass, and reverse search of a flipped image, was discussed with the help of representative examples. Through his presentation, Mr. Teyssou highlighted the usefulness of the developed technology for fake news video debunking, which has already gained some very positive feedback on social media platforms, from experts of the media verification community.

The given presentation can be seen below.

The entire talk of Mr. Teyssou can be seen in the following.

The InVID plugin now with a new launch menu and extended functionalities

New release of InVID Verification Plugin

Check the new version of the InVID plugin (released on January 31st 2018) that contains a new launch menu and extended functionalities for content collection and verification. After fixing a number of bugs, and thanks to the valuable and constructive feedback from the users of the tool, we developed the next version of the InVID verification plugin, which:

  • Contains a new launch popup menu with three options (see image on the right):
    • “Open InVID” opens the user interface of the plugin in a new tab of the browser
    • “Video Urls” allows journalists to identify the video URL in the HTML code of the webpage, open it a new tab that enables the direct download of the video or use it for analysing the video through the Keyframe component of the tool (supports Instagram, Vimeo and Liveleak platforms)
    • “Images Urls” gathers all the existing images in the webpage and permits a more organised inspection of these images through the offered functionalities in the contextual menu of the InVID plugin (supports Instagram, Vimeo and Liveleak platforms)

An example of how the URL of an Instagram video can be retrieved using the newly added functionality is illustrated in the following image.

  • Supports YouTube shorteners in the entire set of integrated video analysis functionalities
  • Offers an enhanced contextual menu
  • Includes the latest version of the Metadata component, that offers a preview of the picture and supports Dropbox and Google drive URLs
  • Integrates the latest version of the Analysis component, which now supports Twitter content and provides a link to for direct convertion to local time
  • Offers Tineye as an alternative reverse search engine, in all tabs where this searching process is applicable

InVID at MIL meeting on social media detection and verification

InVID at MIL meeting on social media detection and verification

The InVID project and the developed technologies for newsworthy media collection and verification, were presented on a meeting focusing on tools for detection and verification of videos shared on social networks, that was co-organized by CERTH/InVID and the Media Informatics Lab of the Journalism & Mass Media Dept. of the Aristotle University of Thessaloniki, on Thursday 14th of December 2017.

An audience (approx. 80 people), comprised by professors, academics and students of the Journalism & Mass Media Dept, journalists and media verification experts, was initially informed about the InVID project by the project co-ordinator Dr. Vasileios Mezaris, who introduced the project’s motivation, goals, overall concept and integrated technologies for newsworthy media collection and verification.

Following, Mr. Evlampios Apostolidis from CERTH-ITI, gave a talk on fake news that rely on video reuse and the way that InVID handles such fakes. In particular, he presented the developed web application for video fragmentation and reverse keyframe search, that assists journalists to perform reverse video search at the fragment-level, and detect previously published versions of the same video online.

Then, Dr. Symeon Papadopoulos from CERTH-ITI, discussed methods for automated detection of fake posts on social media and highlighted the efficiency and functionality of an InVID tool (which was based on one of the outcomes of the Reveal EU-funded project) for contextual analysis. This tool is capable to identify and evaluate verification-related content, and provide clues about the trustworthiness of a social media item to the journalists.

Subsequently, Dr. Markos Zampoglou from CERTH-ITI, presented the developed tools for image forensic analysis. Dr. Zampoglou described, with the help of some representative examples, different types of image tampering, explained the InVID apprach to identidy many of them, and outlined the challenges of this task, the limitations of existing approaches as well as some future directions.

Finally, Mr. Denis Teyssou from AFP, joined the meeting via Google Hangouts and gave a nice presentation about the verification functionalities of the developed plugin for fake news video debunking.

InVID at UN experts’ meeting on Digital Image Authentication and Classification

InVID logo

Members of the InVID team will take part in a focused workshop organized by the UN High Commission for Human Rights (OHCHR) in Geneva on December 6-7.

This experts’ meeting on “Digital Image Authentication and Classification” will look into:

  • how human rights investigations are conducted by OHCHR & NGOs;
  • what image- and multimedia-related problems and technical challenges are encountered in the course of such investigations;
  • and how existing and under-development tools for authenticating, analyzing, and classifying digital images (including tools we are developing in InVID!) could contribute to the work of human rights investigators.
