Generative Artificial Intelligence (GenAI)

This guide provides an introduction to Generative Artificial Intelligence, originally created in Fall 2023 and updated in Winter 2024 by Librarian Greg Bem. Content based on Fall 2023 and Winter 2024 workshops developed by Greg Bem.

Evaluating Images for Authenicity

Questions to ask:

  • Who is posting this image? Is this a reliable source?​

  • What is the purpose of the image? Why is it being posted?​

  • Who is the intended audience?​

  • When is it being posted?​

  • Can it be verified or found elsewhere? ​

  • Can I find images from the moments before or after?​

AI image generation continues to improve. In addition to becoming familiar with common issues in AI generated images, there are different online tools that can help verify the authenticity of an image found online. 

These tools are not perfect. They shouldn't be relied upon completely, but they can be added to your "toolkit" of approaches to use when considering the authenticity of an image.

Reverse Image Search

A reverse image search can show where else on the internet an image can be found. This can help you evaluate whether the image is real by giving more information and sources to investigate for authenticity. 

  • Google Lens: On a computer, click the small camera icon in the Google Images search bar to search by image. On a smartphone, the Google Lens app will offer the same functionality. 
  • TinEye 

AI Detection Tools

Use AI to spot AI? There are a number of websites utilizing AI technology to help identify AI generated media. These can be helpful, but it is good to remain skeptical and not rely solely on this one tool. 

  • SightEngine: This tool evaluates based on the pixel content in an image and claims to be able to identify authenticity of images from popular Ai image generators. 
  • Hive Moderation: A Chrome extension that can process images, text, audio, and video. 

Metadata

Metadata is information about a file that is hidden (embedded) into the file itself. Image files typically contain EXIF data. This can include information on the type of camera or lens, GPS location, time stamps, and copyright details. This information, or the lack of such information, can be helpful in evaluating if a photo was taken by a camera or generated online. However, it should be noted that metadata can be removed from files, so again, this method should be used in addition to other approaches to evaluating image authenticity. 

AI images are relatively easy to generate and access. They may be useful for personal, professional, or even academic purposes (but must be properly cited!). However, there are other options for easily finding copyright-free or limited copyright images.

AI Image Examples

An AI generated image showing a teacher in front of a class. The prompt used to generate the image is also included on the slide:

Classroom Instruction

  • Consider the hands on each person. Are there any issues in these details? In the bottom right corner, do you see anything that doesn't quite make sense? 
  • Would an instructor be likely to use the slide that is shown? 
  • What is on the laptop screen? Does it look realistic?
