title: Feature extraction from Image metadata
body: <p>I am working on a security problem, where I am trying to identify malicious images. I have to mine for attributes from images (most likely from the metadata) that can be fed in to Weka to run various machine learning algorithms, in order to detect malicious images.</p>
  
  <p>Since the image metadata can be corrupted in various different ways, I am finding it difficult to identify the features to look at in the image metadata, which I can quantify for the learning algorithms.</p>
  
  <p>I had earlier used information like pixel info etc using tools like ImageJ to help me classify images, however I am looking for a better way (with regards to the security) to identify and quantify features from the image/image-metadata.</p>
  
  <p>Any suggestion on the tools and the features?</p>
