Abstract
A method to detect a plurality of steganography based information embedded in a multimedia file associated with an online computer environment is provided. The method may include detecting the multimedia file entering or exiting an online environment associated with a network or an organization. The method may also include comparing a stored hashed version of the detected multimedia file to the detected version of the multimedia file. The method may also include comparing a stored perceptual hashed version of the detected multimedia file to the detected version of the multimedia file based on the detected multimedia file not matching the stored hashed version of the detected multimedia file. The method may further include assigning a flag attribute to the detected multimedia file based on the detected multimedia file matching the stored perceptual hashed version of the detected multimedia file.
