Embodiment

[0045] The information hiding and protection method proposed by the present invention is applied to mobile computing devices represented by smart phones. The following is an example where the user wishes to hide and protect the text message "HelloWorld" on the mobile phone. Information hiding process such as figure 1 shown.

[0046] The information encryption process is as follows:

[0047] Step 1: Input the original information, for example, the user enters the text information "HelloWorld";

[0048] Step 2: Select an existing image as a camouflage image, for example, the user selects a landscape image as a camouflage image, such as figure 2 shown;

[0049] Step 3: Divide the image area, for example, the user selects the nine-square grid to divide the camouflage picture, such as image 3 shown. Among them, the display of the dividing line is only for the convenience of operation, and will not be used as an integral part of the image;

[0050] Step 4: Determine the enc...

Abstract

The invention provides an information hiding and protecting method based on an image and belongs to the technical field of computer applications. According to the information hiding and protecting method, original information to be transmitted is encrypted and hidden into an image, a user without a decryption password can only see the disguising image, and setting of an encryption password and a decryption password is completed by operations carried on the image; the operations carried on the image are composed of one behavior conducted on the area of the image by a user or multiple behaviors conducted on the area of the image by the user; during decryption, when the user inputs a correct decryption password, the coding data of the image are read, decrypted original information is extracted from the coding data, and the original information is displayed after the original information is decrypted through the decryption password. The information hiding and protecting method based on the image is high in safety and usability, capable of being applied to a mobile computing platform and a non-mobile computing platform and also capable of being applied to encrypted storage of local information and encrypted transmission or encrypted copying of information, and therefore the information safety of the user is effectively protected.

Description

technical field [0001] The invention relates to a picture-based information hiding and protection method, which belongs to the technical field of computer applications. Background technique [0002] Computer and information technology have developed rapidly in recent years, especially information processing technology based on mobile computing platforms, which has played an increasingly important role in people's production and life. According to information from China Industry Consulting Network, in terms of hardware, it is estimated that by 2016, the number of smartphones in my country will reach 700 million. In addition, in terms of the amount of information sent, in 2012, the number of mobile short messages sent nationwide reached 897.31 billion. In recent years, with the rapid development of new-generation instant messaging systems such as WeChat, people will increasingly use mobile platforms to send messages. [0003] The widespread use of information technology has ...
