  A year has passed since our last report on this topic and the email industry saw huge changes in 2023. In the first half of this article, we report on the latest attack methodology observed by IIJ and discuss the new countermeasures we have started taking against these threats. In the second half, we report on the dramatic changes in sender authentication technology DMARC compliance rates observed over the past year.

• Focused Research(1) "W3C Standardization: RDF Dataset Canonicalization"[649KB]

  In this article, I describe RDF Dataset Canonicalization, which became a World Wide Web Consortium (W3C) recommendation in May 2024. I was involved in the standardization process at W3C. RDF Dataset Canonicalization is an algorithm for canonicalizing (i.e., normalizing or generating a serial canonicalization of) data represented using the Resource Description Framework (RDF). I explain what RDF is, what the process of RDF canonicalization entails, and when it is needed. I also go over the path we took to standardization at W3C and describe the canonicalization procedure in some detail.

• Focused Research(2) "IIJ's DRM Initiatives"[2.19MB]

  DRM stands for digital rights management and refers to technologies used to control copyrights by, for instance, imposing restrictions on the use and duplication of digital content. DRM applies to static content such as text and images as well as digital content in general, including music and games. In this article, I will discuss DRM as it relates to video delivery from the perspective of the IIJ Media Sphere Service, a video delivery platform that I work on at IIJ.
