From the user (100) which possesses the perusona identifier receiving access request is included in this method. Next, the challenge message which includes the verification data like the perusona identifier and the false random data as a part at least is drawn up.

The certification object which is formed is transferred to the user. When certification object is received from the perusona server, the user searches the code-breaking data from the perusona server. If it is the user where the perusona user is legitimate, making use of the data which is searched from the perusona server the certification object package is solved by the security protection functional equipped hardware (104) of the user computer, the verification data is extracted. Receiving the verification data from the user, after verifying, the contents provider (106) permits the fact that it accesses the contents which the user selects.
