Personate photograph producing method used for keep input secret and method of use thereof

Abstract

The invention discloses a generation method and a use method of camouflage picture used in secure input, wherein, a credible machine can be preinstalled with a background picture, a conceptual picture and corresponding conceptual information through other machines; moreover, the conceptual picture and corresponding conceptual information are concealed in the background picture in random distribution; the corresponding relation of the coordinate region and the conceptual information of the conceptual picture is stored to form a camouflage picture; in addition, a camouflage picture preappointed with a person knowing the range is generated through creating concealed appointment mode between an operator and the credible machine. During use, the credible machine which displays a combined camouflage picture and clicks the corresponding area on another machine through a driver judges the character to be input by the operator according to the returned click position coordinate; therefore, the credible machine realizes information input by certain means. Through adopting the camouflage picture based on image, the invention determines the input content through clicking corresponding image position information in the picture by a mouse keystroke; therefore, secure input for computer is realized along with convenience and shortcut in use.

Description

technical field [0001] The invention belongs to the field of computer information, and in particular relates to a method for generating a camouflage picture and a method for using the same, so as to realize safe and confidential input of a computer. Background technique [0002] In the process of receiving, processing and providing data with the help of computers, people will inevitably face the danger of leaking secrets, which is hard to guard against. Inputting with a computer keyboard or clicking characters with a mouse may be discovered and understood by others. Even if security measures are taken, such as encryption, the existing internal information of the computer may be discovered by others or deciphered by programs in the computer. Therefore confidential input is crucial to improving the security in computer use. [0003] In the prior art, in order to prevent leakage of secrets, camouflaged pictures are used for confidential input. Hiding meaningful conceptual inf...

AI Technical Summary

Problems solved by technology

Hiding meaningful conceptual information in a special visual picture makes it easy for people to see the specific image and understand its meaning, but it is difficult or impossible for computers to recognize and understand

However, simple camouflaged pictures, such as the verification code pictures commonly used on websites, are easily recognized by computers because of the insufficient concealment of the camouflaged method and features, thus losing the effect of forcing people to identify

In addition, the current method of using camouflaged pictures is also relatively single, mainly by people reading the symbols in the pictures and then inputting them into the input box. These methods are not suitable for high security systems, because keyboard input cannot prevent Trojans monitor

Simple camouflage and a single application method make the picture very predictable, and it is very easy to be automatically recognized by a Trojan horse program with pattern recognition technology. For example, if you insert an encrypted USB flash drive into a computer with unknown security, you must enter U The password of the U disk, if there is a Trojan horse in the computer, the password of the U disk is dangerous
