Visual semagrams steganography involves concealing messages within visual patterns or images that do not draw attention to the presence of hidden information. This technique uses subtle alterations in visual content that appear normal at a glance, making it less likely for observers to detect that a hidden message is present. For example, the slight modification of an image's pixel color or the arrangement of objects within a visual scene can encode messages that remain unnoticed by the casual viewer.

Open code steganography is focused on using open or overt messages that may indicate a hidden communication method but do not obscure the transmission itself. Text semagrams steganography applies the concept of concealing messages within the text itself, which may be less subtle than visual counterparts. Technical steganography focuses on the methods and technologies used for hiding messages, such as algorithms or protocols, rather than how the messages are camouflaged in unassuming patterns.

In this context, visual semagrams steganography is characterized by its ability to embed messages in a way that blends seamlessly with other visual elements, making it a more effective method for communication without raising suspicion.
