In general, there is a risk with the Internet that the transmitted data and its content can be accessed by malicious third parties. Therefore, the following important information should be transmitted and received securely and safely on the Internet:
With Census Online, the information being exchanged on the communication path is encrypted by SSL/TLS in order to prevent it from being accessed by malicious third parties, etc., thereby enabling safe communication.
Pages on the Internet using SSL/TLS have an address starting with "https://" instead of "http://" and a lock mark is displayed.
▼Example in Microsoft Edge
Encryption by SSL/TLS is achieved as described below.
The browser confirms the following details about the "server certificate".
Depending on the browser used, inability to confirm "whether the certificate was issued by a trusted certificate authority" noted above will result in a warning message like that below being displayed.
This is caused by the self-signed certificate of DigiCert issuing the "server certificate" (called a "Certificate for safe communication" with this system) is not registered to the browser.
<If using Microsoft Edge>
<If using Firefox>
<If using Google Chrome>
<If using Android (Google Chrome)>
The "server certificate" issued by DigiCert for Census Online can be confirmed by double-clicking or clicking the 
mark for your browser.
The "server certificate" is sent from the website accessed when performing encrypted communication by SSL/TLS. By confirming this, the site accessed can be confirmed to be Census Online.
The issuer of Census Online's "server certificate" is "DigiCert SHA2 Extended Validation Server CA".
<If using Microsoft Edge>
The server certificate can be displayed by clicking the mark displayed at the top of the screen.
<If using Firefox>
The server certificate can be displayed by clicking the mark displayed at the top of the screen.
<If using Google Chrome>
The server certificate can be displayed by clicking the mark displayed at the top of the screen.
<If using Android (Google Chrome)>
DigiCert (certification authority) is the certificate authority that issues "server certificate" and "code signing certificate". For details, see the DigiCert (certificate authority) page.
Census Online uses a "server certificate" issued by DigiCert (certificate authority).
In order for a "server certificate" to be confirmed as being issued by a trusted certificate authority, the self-signed certificate (certificate for safe communication) of the certificate authority that issued the "server certificate" must be registered to the browser. Census Online uses a "server certificate" issued by DigiCert (certificate authority); therefore, DigiCert's "Certificate for safe communication" must be registered to the browser.
(DigiCert's "Certificate for safe communication" is registered to your browser.)
The Statistics Act (Act No. 53 of 2007) stipulates that the national administrative organ or local public entity conducting a statistical survey must take measures necessary for managing statistical information related to the statistical survey in an appropriate manner.
Data for answers made using this system shall be managed in an appropriate manner based on this provision. Specifically, the following measures shall be taken at the "communication encryption", "server, etc. administration", "Census Online", and "Census official certification" stages.
All communication from the computer, tablet, or other device sending responses to this system is encrypted.
The servers, etc. of this system are set up in a strictly administered data center and monitored 24 hours a day for intrusion and other unauthorized access.
Response data is stored on this system, but a structure is in place whereby the answer data cannot be obtained or viewed via the Internet, even by the respondent, after a certain period of time. Also, after the Statistics Bureau of the Ministry of Internal Affairs and Communications obtains the data for tabulation processing, it is completely erased from the server so that it cannot be restored.
Only Census officials are authorized to access responses.
Such officials must have an individual-specific ID and password in order to access this system.
Whether or not one is an authorized official is confirmed by individual-specific ID and password.
Personal information collected in statistical surveys based on the Statistics Act, including in census surveys, is not protected by the Personal Information Protection Law, due to the following reasons.
