Abstract

To speed up the process of sending secret messages, we need a medium for small messages that can still guarantee the confidentiality of the messages they contain. GIF (Graphics Interchange Format) is an image format that is one of the most commonly used formats on the web because of its small size and for encrypting the text that is sent. Encryption is carried out at the time of delivery by converting the original data into confidential data, while decryption is carried out at the time of receipt by converting the confidential data into original data. The most common way to hide messages is to use the Least Significant Bit (LSB). This research has succeeded in implementing the LSB algorithm to solve steganography on digital images in GIF format optimally

数字图像中文本隐藏的最低有效位方法的实现
为了加快发送秘密消息的过程,我们需要一种能够保证其包含的消息的机密性的小消息的介质。GIF(图形交换格式)是一种图像格式,它是网络上最常用的格式之一,因为它体积小,并且用于加密发送的文本。加密是在发送时将原始数据转换为机密数据进行的,解密是在接收时将机密数据转换为原始数据进行的。隐藏消息的最常用方法是使用最低有效位(LSB)。本研究成功地实现了LSB算法对GIF格式数字图像的隐写问题的优化解决
