In the context of digital assets, this can involve embedding messages within transaction metadata, using steganography in unrelated files, or employing encrypted channels that appear as benign network traffic. The objective is to convey data without revealing its existence or content to external observers. Such methods are typically employed for privacy or illicit activities.
