A review of methods of embedding information in digital objects for security in the internet of things

Transmission, processing and storage of information in the infrastructure of the Internet of Things are related to the necessity for solving a number of problems in information security. The main difficulty lies in the fact that the infrastructure of the Internet of Things is not homogeneous and contains many different devices, including those with limited computing resources. One of the approaches to solving these problems is to embed additional information into the transmitted and stored digital objects. In this paper we present a review of methods of embedding information in digital data to provide security in the Internet of Things, including methods of steganographic embedding of information and methods for embedding digital watermarks. We reviewed methods of embedding information into digital images, as well as wireless sensor network data, proposed for use in the Internet of Things. In this paper we defined the advantages and disadvantages of individual methods and groups of methods, also we analyzed their applicability for data protection in the Internet of Things. Relevant trends in this field of research have been identified.
