Method for adding secure address book, information communication method and calling method and system

Abstract

The present invention relates to a method for adding a secure address book, an information communication method, a calling method and a system, wherein the method for adding a secure address book includes the method for adding an address book including: user B terminal collects fingerprint information of user A; user B terminal collects fingerprint information of user A according to The fingerprint information of user A obtains the basic user information of user A from the information management server, and the basic user information includes the public key information of the user; the terminal of user B stores the basic user information of user A in the address book. Adopting this kind of safe address book adding method, information communication method and call method and system, no matter it is a short message, multimedia message, or voice call, this technical solution can guarantee that the content is not easy to be leaked during the transmission process; the eavesdropper must go through complicated Only through the cracking process can the plaintext of the information be obtained; whether it is sending SMS, MMS, or voice, all operations are completed internally, and users do not need additional operations. It is very simple and fast, and is suitable for large-scale promotion and application.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to the technical field of mobile phone communication, and specifically refers to a method for adding a secure address book, an information communication method, a calling method and a system. Background technique [0002] Calls and text messages have always been the mainstay of mobile communication services. However, in the current smart phone applications, the security of calls and text messages has not been fully paid attention to and improved. Some confidential or sensitive information (such as important information such as bank card information, personal identity information, intellectual property rights, finance, etc.), often dare not use mobile phone text messages to transmit. And some confidential calls may also be wiretapped and identity forged. [0003] The following list several common communication security control methods in the prior art: [0004] (1) Security ...

AI Technical Summary

Problems solved by technology

[0007] Disadvantages: Can not protect newly received SMS content leakage; can not guarantee the leakage of SMS content in transmission

[0011] Disadvantage: keys must be negotiated in advance

[0021] Disadvantages: too complicated, TF card must be configured, in terms of price and operation complexity, it is not suitable for ordinary users;

[0027] Disadvantages: information must be transmitted multiple times; voice encryption cannot be performed; S->B transmission cannot be guaranteed not to be leaked

[0028] To sum up, the secure short message and telephone communication methods in the prior art are either too complicated or too simple, and cannot meet the security needs of the majority of ordinary mobile phone users.
