1. Background, and other details

　e-Seal" is technology used to certify the source of electronic data issued by companies and other entities, and to ensure that the electronic data has not been tampered with. In March 2025, the MIC issued the Regulations for Accrediting Certification Operations Pertaining to e-Seal (MIC Notice No. 113 of 2025) to establish an accreditation system under which the Minister of Internal Affairs and Communications accredits providers of e-seal certification operations, which function as certification authorities (CAs).

　According to the relevant MIC notice, the provisions concerning specified investigation bodies have already come into force, while those concerning the accreditation of e-seal certification operations by the Minister of Internal Affairs and Communications will come into force within one year from the date of promulgation (March 31, 2025).

2. Designation of specified investigation bodies

　Pursuant to Article 13 of the Notice, JADAC submitted an application for designation as a specified investigation body. Upon examination, JADAC was found to meet the requirements stipulated in Articles 14 and 15 of the Notice. Today, the MIC has designated it as a specified investigation body.

3. Publication of the logo

　The MIC has established an accreditation logo and will publish it. The logo allows providers of e-seal certification operations accredited by the Minister of Internal Affairs and Communications to indicate on their websites, business cards, and other materials that they are accredited.

　The logomark features a ribbon—often used to seal items—as a symbol of sealing information. The design of "information" is intended to evoke a human figure, while the ribbon is intended to evoke the shape of a computer.
