The present invention relates to securities having a forgery prevention function, a method for preventing forgery of the securities, and a method for determining forgery. Securities are printed by a securities printing system comprising: a securities writing device having a function of generating securities printing device identification code information, hash algorithms, and codes; and a securities printing device connected to the securities writing device to print the securities. The method for preventing forgery of the securities comprises: a hash value generation step of generating a hash value from securities information and securities printing device identification code information by a hash algorithm; and a code generation step for generating a code from the hash value. When printing securities, the code generated in the code generation step is printed on the securities.
