An information transmission method and system for protecting privacy

Abstract

The invention belongs to the technical field of communication, and in particular relates to a privacy-protecting information transmission method and a system thereof. The method of the invention includes the identity registration phase of the calling user and the communication phase between the calling user and the called user, and the system of the invention includes a calling terminal, a called terminal, an identity management system and a message server. In this method, the identity token passed between the calling user and the message server does not contain any calling user privacy information, and the original calling user identity information is determined by the user ID i Instead, the calling user information is hidden, but identity verification can be performed at the same time. Even if the message server is attacked and the information is leaked, it will not affect the protection of user privacy. The system of the present invention can only provide services to registered users, so that charging can be carried out. At the same time, through high-speed information transmission, credible identity information can be transmitted before the voice is connected, and credible communication is supported, thereby avoiding the authority of notification calls Calls to agencies and services were refused.

Description

technical field [0001] The invention belongs to the field of communication technologies, and in particular relates to an information transmission method and a system for protecting privacy. Background technique [0002] With the popularization of telephones and mobile phones, telephone communication itself can no longer meet the needs of users. In the telephone communication (the present invention calls the telephone communication channel as the control channel), it is often necessary to send other digital information, such as the caller's identity, the caller's CRBT, the caller's ringing music, the calling purpose, and even digital files. Since the control channel can only send short messages, it cannot carry trusted identity information, let alone electronic digital files. [0003] At present, mobile smart terminals can not only make calls, but also have the ability to connect to the Internet through the intranet, and the smart fixed phone also has the ability to connect ...
