This paper presents the state-of-the-art technical reviews and analysis of recent copy-move forgery detection (CMFD) techniques. A new CMFD process pipeline was introduced. In addition, the techniques used in each stage of the CMFD pipeline are summarized and classified into small categories. Furthermore, the tables of comparison are provided as a quick reference. This technical review paper is expected to help provide useful insights and updated information regarding recent advancements in CMFD to researchers in the field.

Zero trust (ZT) is a new concept involving the provisioning of enterprise/organization resources to the subjects without relying on any implicit trust. Unlike the perimeter-based architecture in which any subject behind the wall (i.e., inside the predefined perimeter) is considered trusted, zero trust architecture (ZTA) processes any request and provides a resource to the subject without relying on implicit trust. In this paper, based on NIST Special Publication SP800-207, the concept of ZT and ZTA is introduced. Also, challenges, steps, and things to consider when migrating from the legacy architecture to ZTA are presented and discussed.
