Secure address book adding method and system, secure information communication method and system, and secure call method and system

Abstract

The invention relates to a secure address book adding method and system, a secure information communication method and system, and a secure call method and system. The secure address book adding method comprises the following steps that a terminal of a user B collects fingerprint information of a user A; the terminal of the user B obtains user basic information of the user A from an information management server according to the fingerprint information of the user A, wherein the user basic information comprises public key information of the user; and the terminal of the user B stores the user basic information of the user A into an address book. Through adoption of the secure address book adding method and system, the secure information communication method and system, and the secure call method and system, the technical scheme can ensure that contents of either short messages and multimedia messages or voice calls cannot be easily leaked in a transmission process; an eavesdropper obtains a plaintext of the information through a complicated cracking process; all operations to send either short messages and multimedia messages or voice calls are completed internally, the user does not need the additional operation, and the operations are very simple and fast, and furthermore, the methods and the systems are suitable for large-scale popularization 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.
