Abstract

Smart home is an emerging form of the Internet of things (IoT), which provides a convenient and comfortable living environment for the smart home users. With the explosive growth of smart home information, people pay more attention to the privacy protection of smart home, including the choice of privacy and effective privacy protection scheme. This paper proposes a privacy protection scheme based on information hiding, the scheme guarantees the sensitive data transmitted securely. First, the smart home Real-time sensor data are classified into sensitive data and non-sensitive data through machine learning, the process can be controlled according to the user's preferences. Second, the sensitive data can be transmitted securely by ordinary channels using method of combination encryption with information hiding. Experiment results show that this scheme can help users to express their preferences to the privacy protection, changing the previous practice that users can only accept the privacy settings provided by the supplier. What's more, the scheme combines encryption with information hiding, providing a double guarantee for the sensitive data during they are transmitted on ordinary channels. Comparing to the previous practice of using encryption merely, this scheme greatly improves the security of data transmission and is more suitable for the real environment.

Highlights

With the advent of the Internet, the number of Internet of things (IoT) connected objects surpass the population of earth’s human in 2010[1]
The experiment shows the scheme proposed in this paper can realize the safe transmission of smart home data after they are classified into sensitive data and non-sensitive data according to users’ preferences; the combination of TTMSB information hiding method and EDS encryption can make up for the deficiency of data concealment transmission when using encryption technology only, it can realize the covert transmission of information effectively
This paper proposes a scheme based on information hiding, it combines DES encryption algorithm with TTMSB information hiding method to protect the privacy of smart home system, during the sensitive data are transmitted

Summary

INTRODUCTION

With the advent of the Internet, the number of IoT connected objects surpass the population of earth’s human in 2010[1]. Cryptographic-based encryption is to encrypt data into unreadable code, it is more likely to attract the attacker’s attention Once these ciphertext is intercepted, the attacker will try to decrypt these ciphertext to obtain some useful information, so as to carry out some illegal activities. TTMSB information hiding method proposed by this paper has well performance of robustness and concealment It is suitable for data-centered sensor networks and can protect data security with lower computing overhead. The experiment shows the scheme proposed in this paper can realize the safe transmission of smart home data after they are classified into sensitive data and non-sensitive data according to users’ preferences; the combination of TTMSB information hiding method and EDS encryption can make up for the deficiency of data concealment transmission when using encryption technology only, it can realize the covert transmission of information effectively
