1. The shortcomings of current communication methods

At present, with the popularization and application of mobile Internet, people can use many convenient communication methods to realize personal communication or business communication. However, as people gradually pay attention to the protection of online privacy and the security of communication privacy, all existing communication methods have some problems, specifically:

  1. First, Paper Letters. Writing letters is the best way of communication in the era when communication is still underdeveloped, and its advantages now seem to be many more meanings. From ancient times to the present, and only now in the 21st century, writing letters gradually began to be forgotten, and we have had a more convenient way to get in touch with people. People are grateful for the great convenience brought to life by the advancement of science and technology, and they gradually forgot the other deep meanings of writing letters. The disadvantage of writing letter is that the delivery process is too slow, even if it is an express delivery, the delivery will take the next day.
  2. Second, Telephone Communication. The telephone is a modern communication tool, divided into landlines (wired phones) and mobile phones (wireless phones). Although they have begun to be less used now, they are still one of the main communication methods, it is very convenience and can hear the other party's voice. The disadvantage is that the international long-distance call is expensive, and it can only be voice, and the other party cannot be seen. There are also issues that may disturb the other party.
  3. Third, Email Communication. Since the beginning of the Internet, there has been email, turning traditional paper letters into electronic letters, which can be delivered in real time via the Internet, while the content of the letters is still typed and written by users. It is completely free and will not disturb the recipient. Email can be text, files, voice and small video, etc. Its only disadvantage is cleartext transmission and cleartext storage in cloud, not in people’s hand, and there is no guarantee that the email content will not be illegally stolen or tampered with.
  4. Fourth, Instant Messaging. Also known as chat software. Since emails require the recipient to go to the mail server to receive them in real time, ICQ software has opened the communication method of online real-time chat, and some social media also have the chat function now, which is very convenient and fast. However, there is a problem of disturbing the other party, and it is a centralized communication method. The communication content is relayed through the service provider's server, and there is a risk of leaking confidential information.
  5. Fifth, Social Network. It is a form of network service with human socialization as the core, and it also provides instant messaging and information publishing functions, but it is no longer outside the scope of peer-to-peer private communication.

2. MeSign encrypted communication solution

(4) Encrypted email has the same value of family, friendship and collection as paper letters, but it completely solves the problem that paper letters are too slow, and it also completely solves the problem that paper letters are difficult to store for a long time. Encrypted email can be securely stored permanently in personal mailbox or business mailbox, without worrying about the loss and damage of paper letters.
  5. (5) Encrypted email can be set to be received in real time. The immediacy is not bad for instant messaging, and it can even be said to be better than instant messaging (chat), because instant messaging has the problem of disturbing users, and encrypted emails can be received when people are free or want to receive emails, it will be automatically received in the inbox silently instead of being passively interrupted, which will never be as annoying as instant messaging.
  6. (6) Encrypted emails are not only encrypted transmission and encrypted storage of messages, but also direct end-to-end delivery. They will not be transferred through a central server like chat. The central server may save and permanently own the chat messages, which cannot guarantee the chat messages proprietary and confidentiality.
  7. (7) Encrypted email can be permanently encrypted and stored in the mail server, but chat information cannot be stored permanently.
