Abstract
A method, an information handling system (IHS) and a validation system for validating an image using an embedded hash. The method includes retrieving, via a controller, a first image from a first memory device and extracting a first hash from a first location within the first image. The first hash was previously generated using an original set of data that includes a first data string, and the first image includes the first hash inserted into the first location to replace the first data string. The method includes retrieving a copy of the first data string. The method further includes generating a second image by inserting the first data string into the first location from which the first hash was extracted such that the second image contains the original set of data. The method further includes validating the first image using the first hash and the second image.
