Abstract: Methods and systems are presented for using blockchain technologies to establish and manage personal profiles for users. A credential system registers a user by generating a token associated with a blockchain for the user, and storing authentication data associated with the user in the blockchain. The authentication data may include encoded data that represents an identification document and biometric data. After registering the user with the credential system, a verifier device can authenticate the user via the credential system using the authentication data stored on the user device. Additional information, such as interaction data associated with the user's interaction with various computer system can be added to the blockchain using the token generated for the user. The interaction data of the user with various computer systems, collectively, forms a universal personal profile of the user, and can be used by the various computer systems to manage the user.

Abstract: Methods and systems are presented for using blockchain technologies to manage the life cycle and authentication of artificial intelligence (AI) agents. When an AI agent is created, the AI agent registers itself with an authentication system. The authentication system creates identity information for the AI agent and store on a blockchain. The identity information is used to track the changes of the AI agent through its life cycle, including upgrading of the binary code, transfer of ownership, change of a delegator, and others. When the AI agent requests for access of one or more resources, the authentication system uses the information stored on the blockchain to authenticate the AI agent before granting the AI agent access to the one or more resources.

Abstract: Methods and systems are presented for analyzing feedback data associated with a content and generating an interactive graphical representation of the feedback data. Upon receiving a request from a user, a feedback analysis system may access feedback data associated with a content from a content hosting server. The feedback data may include comments submitted by viewers of the content. The feedback analysis system may analyze the comments and generate an interactive graphical representation of the feedback data. The interactive graphical representation may include icons that represents keywords that are relevant to the comments and sentiments of the viewers derived based on the comments. Upon receiving a selection of an icon, the feedback analysis system may present a comment that corresponds to the keyword and/or sentiment represented by the icon.
