Blockchain Based Secure Communication Application Proposal: Cryptouch

Abstract

The convergence which brought with the globalizing world, highly affects the network and the communication sectors. Mostly closed source and centralized systems are used for network and communication. This contradicts with the information security principles and privacy. These centralized systems can not fully meet the concept of transparent, reliable, fast and uninterrupted communication. Distributed, decentralized and also transparent communication is possible with the blockchain technology. In this study, a communication application which is based on blockchain technology is proposed. InterPlanetary File System (IPFS) is preferred to overcome the limits of the blockchain. A prototype implementation called Cryptouch is proposed. Application features and potential benefits are discussed.
