To obtain a method for anonymously transmitting web site user infor mation by allowing a web site operation computer to automatically perform dynamic access to user information and enciphered user identification while a user is connected with a web site.

The dynamic generation of a user different name is automatically operated each time an internet computer 10 transmits user information records, and this user different name is not stored. This user's alias name is generated based on the real identification (name) of a user so that this user's alias name can be the same identification for the same user each time this user's alias name is generated. When the same internet web site 18 is visited by the same internet user computer 10, the same user different name is linked with the user information records. Therefore, the real identification (name) of the user can be prevented from being leaked to the web site 18 or found out.
