Steganography is leveraged to store additional data in the existing data on any given electronic storage. For example, a first request to store a first electronic file is received. Based on the first request, a determination is made as to whether one or more second electronic files meet one or more predefined criteria for being a carrier file for steganography. If the one or more second electronic files meet the one or more predefined criterion for being a carrier file, the first electronic file is electronically stored into the one or more second electronic files using steganography.
