A high embedding capacity image steganography using stream builder and parity checker

Abstract

Steganography is one of the arts and sciences of securing or hiding secret information in some cover media. In the present study, a new steganography technique is developed to hide large data in Bitmap image using stream builder and parity checker. This method uses the concept of odd and even parity for embedding and extracting of secret message. This method is an improvement of Least Significant Bit (LSB) method for hiding information in images. The proposed method can hide large data in a single Bitmap image retaining the advantages and discarding the disadvantages of the LSB method.

An Intelligent Food Inventory Monitoring System using Machine Learning and Computer Vision

“…When a user edits a wishlist item, the stock of the item could be updated, and how many of the item the user wants is also constantly modified. As a result, these two pieces of information are asynchronous, requiring real-time updates, and thus, a StreamBuilder, shown in Figure 5, is implemented [12]. The StreamBuilder widget treats these real-time data as streams, and since these data are stored in Firebase, it takes a stream that constantly requests a snapshot of the user's wishlist in the Firebase.…”

Variant of LSB Steganography Algorithm for Hiding Information in RGB Images

“…It is observed that efficiency of the approach is highly attributed to the number of eligible pixels, with the moderate number of eligible pixels producing better results. On the other hand, Islam [11] used 24-bit bitmap image for embedding messages using stream builder and parity concept. One stream is built by aggregating LSBs of 8 bytes of pixels and then parity values of these pixels decide how the message will be embedded.…”

“…From the Table 6, it is observed that our proposed approach is able to produce better capacity and PSNR value compared to approaches introduced by Mandal and Das [19], Lin, et. al., [30] and Islam [11]. Moreover, although methods proposed by Wu, et.…”

Improving the non-filtering steganographic algorithm using LSB verification method

“…For this above reason Steganography is more reliable than Cryptography. Figure-1 shows the main categories of file formats that can be used for Steganography [5]. Almost all digital file formats can be used for Steganography.…”
