Researchers have proved the ability of peculiar magnetic materials to hide magnetic information and reveal it under certain conditions and at room temperature.
Since the 1950’s, magnetic materials have been used to store all kinds of information. Magnetically stored information is convenient because it is easily accessible using very well-known magnetic data reading procedures. However, sensitive information must be carefully stored to ensure confidentiality; thus easy access becomes a bad instead of a good feature. The optimal way to prevent unauthorised information access is to make it invisible.
