Abstract: A mechanism for building decentralized computer applications that execute on a distributed computing system. The present technology works within a web browser, client application, or other software and provides access to decentralized computer applications through the browser. The present technology is non-custodial, wherein a public-private key pair, which represents user identity, is created on a client machine and then directly encrypted by a third-party platform without relying on one centralized computing system.

Abstract: Described are techniques for establishing secure communication channels between user devices and service providing devices. Correspondence between a request received from a user device and security data may be used to determine that the user device has provided a valid access credential. The access credential may be replaced with a subsequent access credential after use. Correspondence between the request and service data may be used to determine that the request may be processed by the receiving service and that the user device has the permissions necessary for the request to be processed. Portions of the request that meet these criteria may be provided to the service. The secure communication channel may also be used to provide the response from the service to the user device.

Abstract: The invention has disclosed a method for user identity tracking, and is suitable for wireless Internet. Precisely, mobile phone client end or WAP website sends user access request and parameters; user identity recognition server judges whether the user access request is for the first time; if so, it will distribute a unique user identifier, insert the user identifier in the returned information, and guide the mobile phone user to access the user identity recognition server based on the user identifier; read the recognition file on mobile phone, and complete the recognition of mobile phone user identity according to user identifier. With the technical proposal of the invention adopted, it is possible to realize the recognition on user identity through distributing the user identifier or through the corresponding relations between user identifier and users' mobile phone number.
