Medex Changelog

Includes the following updates:

• Datetime-based tests
  • Over the years we have noticed a consistent behavior with Apple embedded dates that provides a signal whether the file is the original file created on the device, or whether the file is a successor to the original for one reason or another. We have added dynamic tests that focus on these datetime values and reports on them when they are of significance in the automated analysis results within the Medex Insights area.
• Generational History simplification
  • You’ll notice that we have simplified the data we report for Last Generation results in the Structural Analysis area of the platform. You will now see a distinct list of Last Generations that we are matches structurally to the file being analyzed.
• Updated Parsers
  • We are always improving our forensic file format parsers to ensure you have comprehensive and transparent results. This fix includes support for Apple-specific data fields so that they do not interrupt the parsers’ efforts to find all valid boxes in a file.

After an incubation period, we are releasing a significant frontend update to the Medex Video Authentication Platform.

Here’s a short explainer video to see the changes in action.

This release will includes the following.

Significant transformation of the File Examination Result page:

• The option to request Advanced Analysis has been relocated to the “Action” dropdown menu on the File Examination Result page.
• The option to explore the internal structure of the file has been relocated to the “Action” dropdown menu on the File Examination Result page.
• The file’s name and the date and time of the examination are now elegantly displayed as a prominent header on the File Examination Result page.
• To enhance user experience, we have relocated the File Summary section to the top right of the File Examination Result page. In order to streamline the page and reduce clutter, the data in this section is initially hidden but can be easily revealed by simply clicking the chevron located in the top right corner of the section.
• To declutter the page and create a seamless user experience, we have relocated the user Comments section to the top right of the File Examination Result page, just beneath the File Summary section. In order to maintain a clean interface, the data in this section is initially concealed, but can be easily revealed with a simple click on the chevron located in the top right corner of the section.
• The Structural Analysis section on the left side of the File Examination Result page now houses the Structural Signature section, accompanied by a “View Signature” button that allows users to easily access and view the file’s structural signature.
• The Medex Classifier section has been renamed the Attribute Similarity Analysis section.
• The Proprietary Structural Data and Unknown Structural Data sections now appear in the left column of the File Examination Result page just under the Attribute Similarity Analysis section.
• The File Metadata section has been renamed Decoded Metadata and has been moved to the right column of the File Examination Result page.
• The new beta Medex Insights section is now displayed at the top of the left column of the File Examination Result page.

New Product Behaviors:

• The Project Summary page now features auto-refresh. No longer will you need to refresh the page manually while you await results for your file analyses. The page will auto-refresh every thirty seconds until all files in the project have been completely processed.
• We have eliminated the concept of a “Partial Match.” Previously, this match was based on a limited structural signature to identify file relationships when a full structural signature match was not found. However, in order to enhance user experience and reduce unnecessary information, we have decided to remove it. Now, you will only see reports of “Full Match” or “No Match” in the Structural Analysis section of the system.
• We are excited to announce the addition of new columns on the Project Summary page, providing you with more useful and accurate data to compare files within your project.
  • Match: If we made a full signature match to the structural signature of your file, then you will see a green check mark in this column. If we did not make a match, then there will be no green check mark in this column.
  • Signature: If we made a full signature match to the structural signature of your file, then you will see the Medex Reference Library identifier for the signature in this column, e.g., “rl.881.” If we did not make a match, then you will see a Project File identifier for the signature in this column, e.g., “pf.1234.” This identifier is still a unique identifier for the signature, so you can use it to group files together based on their signatures within the Project Summary table.
  • Brand: If we made a full signature match to the structural signature of your file, and if we have only seen one distinct Brand generate that signature in our Reference Library, then we will display the brand here. If we have seen more than one Brand generate that signature, then we will display Multiple here. If we did not make a match to the structural signature of your file, then we will not display any value here.
  • Model: If we made a full signature match to the structural signature of your file, and if we have only seen one distinct Model generate that signature in our Reference Library, then we will display the model here. If we have seen more than one Model generate that signature, then we will display Multiple here. If we did not make a match to the structural signature of your file, then we will not display any value here.
  • Last Generation: If we made a full signature match to the structural signature of your file, and if we have only seen one distinct Last Generation generate that signature in our Reference Library, then we will display the generation name here. If we have seen more than one generation generate that signature, then we will display Multiple here. If we did not make a match to the structural signature of your file, then we will not display any value here.
  • Structural Consistency: If we did not detect any inconsistencies in the binary structure of your file, then we will display a green check mark here. If we found anything out of the ordinary in terms of the binary structure of your file, then we will display a red warning triangle here.
  • Status: Indicates the status of processing your file, e.g., Processing, Complete, Error.
• As an official contributing member of the Coalition for Content Provenance and Authenticity (C2PA), we have introduced the ability for Medex to recognize and validate C2PA manifests if they are present in a video file. Medex will display a box alerting you to the presence of a C2PA manifest. If present, Medex will attempt to validate the manifest and will report whether it is valid or invalid. Medex will also allow you to view the embedded JSON of the manifest to review the data present within it. Learn more about the Coalition for Content Provenance and Authenticity (C2PA).
• Introducing our groundbreaking feature – Medex Insights! Get ready to unlock a whole new level of analysis with our automated logic that highlights the key attributes and features of your file. From originality and brands to models and last generations, we’ve got you covered. This beta section is designed to test its effectiveness, so we value your feedback. Let us know if Medex Insights are helpful by responding to the prompt within the section.
