Problems solved by technology

[0003] On the one hand, when people need their own personal data, they need to prepare paper or electronic materials (such as the personal electronic ID card in the card bag) and give them to a third party. These personal data are often not issued by the individual themselves. The residence permit needs to be applied for at a government agency, and many times a business needs to use multiple materials, and the user needs to apply at multiple different agencies before collecting all the materials, which brings great inconvenience to the user

On the other hand, due to the increasingly prominent problems of user data leakage, user privacy violation, illegal collection, and use of user data in the Internet era, at present, the authorized use of user data to third-party organizations or platforms is generally based on paper-based carriers or electronic forms. Authorization, when user data is abused or stolen for business or verification, it is difficult to be identified and cannot be traced, resulting in damage to personal interests
