Embodiment Construction

[0062] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0063] A method for securely transmitting data provided by an embodiment of the present invention can implement securely transmitting data between a first terminal and a second terminal, or between a second terminal and a server. see figure 1 As shown, the method is applied to the second terminal side, specifically including steps 101-104:

[0064] Step 101: Identify the two-dimensional code provided by the first terminal, determine the server address, port number and encrypted verification field contained in the two-dimensional code, the verification field includes the verification code and the transmission identification corresponding to the first terminal, and tr...

Abstract

The invention provides a method, a device and a system for securely transmitting data. The method comprises the following steps: identifying a two-dimensional code provided by a first terminal; decrypting an encrypted check field according to a preset decryption key, and determining a check code and a transmission identifier; when the check field is correct, sending a second data transmission request to a server according to a server address and a port number, wherein the second data transmission request includes a local flag and the check field encrypted according to the decryption key; and receiving an encryption protocol issued by the server after the validity of the second data transmission request is verified, and transmitting data to the server according to the encryption protocol. The method only needs to identify the two-dimensional code, and is easy to operate. Moreover, a user name and a password do not need to be input, and the operation process is safe, so that the problemof leakage of the user name and password is solved. Moreover, no information is transmitted to the server before correct identification of the check field in the two-dimensional code, thereby effectively preventing the second terminal from connecting an illegal server by mistake and avoiding information leakage.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method, device and system for secure data transmission. Background technique [0002] Currently, between two devices, such as between a mobile phone and a PC (Personal Computer, personal computer), two transmission modes, contact and non-contact, are generally used. [0003] Specifically, the contact transmission method uses a data cable; the problem of this method is that the plugging and unplugging of the data cable is very easy to be infected with viruses, and a corresponding driver needs to be installed. [0004] Non-contact transmission requires a proxy transfer server. Generally, proxy servers provide authentication means for security needs, and the process of entering user names and passwords is cumbersome; and it is easy to be peeped by others, and there is a risk of leaking account numbers. Contents of the invention [0005] The invention provides a method...
