I. Introduction
Following the annual Mobile Visual Networking Index study, the results of which were presented by Cisco [1], in 2022 the share of video in the global mobile traffic reached 79%, while the mobile traffic is 930 exabytes per year. In 2023, worldwide Internet video traffic is expected to comprise 82% of all consumer Internet traffic, compared to 73% in 2017 [2]. A considerable amount of different video content can be used as containers to hide information from human eyes. Steganography is a science exploring various methods of concealing information in multimedia objects, which should remain undetectable both statistically and for human perception.
