Embodiment Construction

[0067] In order to express the objectives, technical solutions and advantages of the present invention more clearly, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0068] In the embodiment of the present invention, the input content is intercepted when the input method is loaded, and the input content and the digest of the input content are encrypted by the public key of the counterpart user and the private key of the local user, respectively, and then sent to the counterpart user with the local user ID; The digest of the input content is decrypted using the public key corresponding to the local user ID, the input content is decrypted by using the private key of the opposite user, and the digest of the decrypted content is generated from the input content. If the digest of the decrypted content is the same as the digest of the input content, the decryption is successful and the input conten...

Abstract

A method capable of guaranteeing safety of inputted content comprises steps of capturing inputted content when calling in an input method; utilizing opposite user identification to calculate to obtain a corresponding public key of the opposite identification, encrypting the inputted content by the opposite identification, and utilizing private keys of local users to encrypt the inputted content; encrypting and decrypting abstract of the inputted content according to the public key corresponding to the private keys of the local users to achieve the abstract of the inputted content, using the private keys corresponding to the opposite user identification to encrypt and decrypt the inputted content, and converting decrypted inputted content into decrypted inputted content abstract; and displaying decrypted inputted content. The invention further discloses a device capable of guaranteeing the safety of the inputted content, a transmitting end capable of guaranteeing the safety of the inputted content and a receiving end capable of guaranteeing the safety of the inputted content. By means of an embodiment of the method, the device, the transmitting end and the receiving end, transmitting object identification is utilized to encrypting the inputted content so as to guarantee the safety of the inputted content.

Description

technical field [0001] The present invention relates to the field of network technologies, and more particularly, to a method, a device, a sending end and a receiving end for ensuring the security of input content. Background technique [0002] The Internet has now become a virtual platform corresponding to real life. More and more information is transmitted and published in the network, and confidential information and personal privacy information are no exception. Network security is receiving more and more attention. [0003] At present, when network users transmit input information to each other, they have not formed the habit of information authentication. Criminals can easily use related software to intercept the information transmitted by network users. For example, users communicate through chat tools, and installing a Trojan horse on a user's computer can smoothly obtain the input information between the users. The same problem exists with email. Hackers can us...
