Realization Model of Personal Data Rights Based on Blockchain Technology

In the era of artificial intelligence, personal data is the nourishment for many artificial intelligence algorithms. Some face recognition, voice recognition and other algorithm models must be fed with personal data to bring commercial value. Therefore, various technology companies currently collect user data while providing services, and apply user data to various commercial purposes, such as precision marketing. These companies use users' personal data for revenue. However, as the owner of their own data ownership, individuals cannot obtain any benefits from it, and even in the process of data circulation, they are subject to various harassment and infringements due to personal data being leaked. Blockchain technology benefits from the application of key pairs of asymmetric encryption technology in cryptography, which can prevent data from being copied at will. It cannot only protect user privacy, but also enable personal data to circulate among various business entities, and it can also enable individuals to obtain benefits in the process of their own data circulation. This article proposes a model for the realization of personal data rights and interests based on blockchain technology. Individuals, companies or institutions with a large amount of user data, personal data account banks, personal data regulators and other parties, under the support of blockchain technology, are in their proper place, develop in benign cooperation, and share the results of data economy together.
