摘要
Data security is a long-term challenge that spans the whole history of human society, particularly in the field of commercial activities and military actions. To date, a variety of data protection techniques have been developed. Early examples include watermarks and holograms.[1] Later, color-shifting inks and luminescent patterns had been developed as well.
