An Improved Method for Hiding Text in Image Using Header Image

Abstract

The necessities of steganography methods for hiding secret message into images have been ascend. Thereby, this study is to generate a practical steganography procedure to hide text into image. This operation allows the user to provide the system with both text and cover image, and to find a resulting image that comprises the hidden text inside. The suggested technique is to hide a text inside the header formats of a digital image. Least Significant Bit (LSB) method to hide the message or text, in order to keep the features and characteristics of the original image are used. A new method is applied via using the whole image (header formats) to hide the image. From the experimental results, suggested technique that gives a higher embedding of several stages of complexity. Also, LSB method via using the whole image is to increase the security and robustness of the proposed method as compared to state-of the-art methods.

Analysis attackers’ methods with hashing secure password using CSPRNG and PBKDF2

“…When retrieval of plain text is required, cryptography is the appropriate method, using a key for encryption and decryption [1]. As for hashing, it is one-way and cannot be decrypted, a hacker can try to reverse engineer it [2]. As nothing is safe online, even computers that are not connected to the Internet are not completely secure, which is why passwords are used, not to ensure that attacks will not happen, but to reduce the risk [3].…”
