Research on Energy Blockchain Platform Based on Private Key Storage Algorithm of Image Information Hiding

Abstract

With the adjustment of the world’s energy structure, the proportion of clean energy represented by renewable energy is increasing. In response to the shortcomings of renewable energy instability, researchers have proposed the concept of the microgrid. However, with the expansion of the scale of the promotion of the microgrid, the traditional energy distribution system with the sales company as the core exposes the shortcomings of being inflexible. Based on this researcher’s continuous exploration of new energy trading models, the energy blockchain has developed rapidly in recent years. Reliable private key storage is a necessary guarantee for the security of energy blockchain services. At present, blockchain private key storage technology still has many security risks in the new energy transaction mode. This paper first builds an energy blockchain platform inside the microgrid, so that all participants can complete energy transactions more safely and conveniently. At the same time, the energy blockchain private key storage technology based on image information hiding is proposed. The blockchain private key is hidden in the watermark information and embedded in the carrier image. A watermarking algorithm based on discrete wavelet transform and quantization index modulation is used to accurately extract the blockchain private key. Finally, the feasibility and security of the algorithm are proved by an example test analysis.
