ABSTRACT:
A publication system effective and secure to the publication agency and a user is provided for the publication agency, and a signature verifying function using the published signature log entries is provided for the user. The publication agency publishes a signature log entry received from the users on the Web, and acquires a time-stamp at the time of the publication, and transmits the time-stamp together with a publication notice back to the user. The publication agency also has the signature log, and either discloses part of the log at regular intervals in a newspaper or the like, or produces publication-purpose data based on the signature log entry received from each user, and publishes the data in the newspaper. The publication agency, after the newspaper publication, transmits the signature log of the publication agency to the user.
