The "Originator Profile Collaborative Innovation Partnership" (hereinafter "OP-CIP"; Chief Director: Jun Murai, Professor Emeritus and Senior Advanced Research Project Professor, Keio University) aims to realize a safe Internet space by preventing the spread of disinformation and misinformation through the development and social implementation of originator identification and tamper detection technologies. We are pleased to announce that OP-CIP and Tottori Prefecture co-organized a briefing session for local governments.
■ Key Points

2. Event Details
- The final number of seminar viewers was 30 (from 14 prefectures and 7 municipalities), with participants from a wide range of regions, from Tohoku to Kyushu.
- Tatsuya Kurosaka, Secretary-general of OP-CIP, explained the usefulness of OP to local government representatives, stating, "With disasters occurring across Japan, the authenticity of information originators is being questioned. Until now, the Internet lacked an established means to identify the source of information. OP enables the receiving side to verify its authenticity."
- Kosaku Shimoda, Director General of the Digital Bureau of Tottori Prefecture, explained the prefecture's challenges toward realizing a safe Internet space, stating, "We are promoting initiatives based on three pillars: 'preparing' for disinformation and misinformation, 'conveying' information about Internet literacy, and 'showing' the originator of the information through OP." He then introduced their efforts regarding OP and called on participating local governments to consider its introduction.
- Indicating a high level of interest, participants asked questions such as "Which browsers are supported?" and "Is maintenance of digital certificates required?"
■ Positioning of OP Technology
In FY2026, this partnership applied for the Ministry of Internal Affairs and Communications' "Development and Demonstration Projects for Countermeasure Technologies against Dis-/Mis-information on the Internet" and was adopted for the "Development and Demonstration for the Social Implementation of 'Originator Profile,' Enabling the Identification of Content Originators and Tamper Detection".
■ What is OP Technology?
OP is a technology that makes the information verifiable identifying the originator by attaching a profile certificate using digital signature technology to each article or advertisement on the Internet. For companies such as media companies or advertisers, third-party organizations (like industry associations to which they belong) can digitally verify the existence of the organization and the fact of their membership. Because it enables the verification of not only self-certification by the originator but also confirmation by a third-party organization, it becomes easier for citizens to judge the trustworthiness of information. We are aiming to provide a mechanism where Internet users can verify the authenticity of the information by displaying it on their web browsers.
