The problems and defects of existing anti-forgery system was analyzed and the method of applying digital identity to drug industry was also put forward in this paper

which realized anti-falsification

retrospect and flow direction track.Methods of destroying verification code while opening the package and ways of feeding back drug information

codes and flow direction track that was returned to customers while checking were put forward in this paper.JUNA lightweight digital signature technology was used to design a drug anti-forgery and tracing system.Digital identity formed from JUNA is only 16 characters long expressed by base-32 system

which can solve the problem of unsafe secret key and too long signature.Finally

constructing cloud computing platforms test center was taken into consideration.
