Design and implementation of commercial SMS supervision model based on blockchain

With the rapid development of the telecommunications industry, commercial short message service (SMS) provides enterprises with low-cost marketing channels. The increasing illegal marketing behavior not only causes troubles for mobile users, but also has a negative impact on the normal supervision of the industry. Under the traditional operation mode, it is challenging to know whether enterprises or service providers (SP) provide commercial SMS according to the wishes of mobile users. Another reason that makes the regulation of commercial SMS more challenging is the lack of transparency in the identification of business entities in the existing commercial SMS service model. Usually, the business SMS service process will generate corresponding communication records, called “Call Details Record” (CDR). When dealing with user complaints or violations, industry regulators spend a long time verifying the effectiveness of CDR, which is also one of the reasons for the decline in the supervision of commercial SMS. In view of the above problems, this paper proposes a commercial SMS supervision model based on blockchain that uses blockchain technology to optimize the traditional SMS supervision methods and combines smart contracts and asymmetric encryption algorithms to achieve the security and trust of CDR management. The model aims to solve the problems of fuzzy identity of business subjects in commercial SMS, difficulty in CDR traceability of commercial SMS, and long time-consuming CDR verification in the process of SMS supervision. At the same time, the model is conducive to reducing the obstacles of data sharing among multiple parties. Finally, this research designs and implements a business SMS supervision prototype system based on blockchain under Hyperledger Fabric. The performance test results demonstrate the feasibility of the model proposed in this research.
