Problems solved by technology

[0002] The anti-counterfeiting of digital multimedia information has the characteristics of accurate and efficient identification. Today, with the popularity of smart phones and the Internet, the identification is very convenient and accurate. It does not require instruments, tools, or professional knowledge and ability. However, there is a fatal flaw that digital information is easy to be copied. A good solution is to supplement it with carrier anti-counterfeiting
