A method may include receiving a data unit and identifying a state of a memory storing data units. The original image is guidedly perturbed into a first plurality of recognizable uniquely perturbed images, each of the first plurality of recognizable uniquely perturbed images being recognizable as representing the target and distinguishable from the original image. An ESI may represent a logical entity that identifies a grouping of elements of a network or network device and associated attributes. This configuration prevents inverse rotation due to rapid further growth of tissue.
