Multimedia internet of thing secure communication method based on information hiding technology

Abstract

The invention relates to a multimedia internet of thing secure communication method based on the information hiding technology, comprising a data service module, an encrypting module, an information hiding module, a data transmitting module, an information hiding core and an API (application programming interface). The data service module is used for providing multimedia carrier data or to-be-transmitted hidden data according to the application scene of the internet of thing; the encrypting module is used for encrypting and pretreating the to-be-transmitted hidden data; the information hiding module is used for embedding the pretreated hidden data into the multimedia carrier data; the data transmitting module is used for safely transmitting the multimedia carrier data into which the pretreated hidden data is embedded; the information hiding core is used for managing the transmission of data among the modules comprehensively and coordinating the work process of the modules; and the API is used for providing flexible interfaces for the use to call the function of the system. The method provides a complete multimedia internet of things secure communication solution which has significant theoretical and applicable values and realizes the secure communication of the multimedia internet of thing.

Problems solved by technology

Although traditional cryptography has good solutions to data confidentiality, authenticity, and non-repudiation, for the application scenarios of the multimedia Internet of Things, traditional cryptography has the following problems: First, encryption may make data unreliable. Therefore, it has an impact on the dissemination of multimedia data; secondly, encrypted multimedia data is easy to attract the attention of attackers, and once the data is decrypted, it can be spread arbitrarily and cannot obtain any form of protection; thirdly, traditional encryption The method does not consider the characteristics of multimedia data; in addition, the traditional encryption method with high security has high time and space complexity and a large amount of calculation, so it is not suitable for the multimedia Internet of Things environment with insufficient computing power and limited energy resources.

At present, the information hiding technology and information hiding detection technology at home and abroad have developed to a relatively mature stage. They have important applications in copyright protection, information authentication, anti-counterfeiting marks, tampering reminders, and confidential communications. Feasible scheme to apply information hiding technology to secure communication of multimedia Internet of Things
