Recently, reversible data hiding in encrypted image (RDHEI) has attracted extensive attention, which can be used in secure cloud computing and privacy protection effectively. In this paper, a RDHEI scheme based on redundancy transfer and sparse block encoding is proposed. Content owner first utilize...
Multi-domain Reversible Data Hiding in JPEG Images Images reversible data hiding is a technique to embed additional data by modifying carrier images in a recoverable way, that has attracted more and more attention, especially for the most widely used JPEG format. As data carrier or modif... W...

In this paper, we propose a data hiding technique specific to the H.264/AVC video format based on the motion vectors. We achieve the purpose of data hiding by modifying motion vectors to their neighboring points within 16 grids. Experimental results show that our method can maintain a good ...
2. Data hiding by simple LSB substitution In this section, the general operations of data hiding by simple LSB substitution method is described. Let C be the original 8-bit grayscale cover-image of pixels represented as (1) M be the n-bit secret message represented as ...
This is a current spreadsheet I am working on - it is to record book sales. All the repeating data, I want to make blank until the blank areas are filled in...
Moreover, the combination of information hiding and secret sharing based on QR codes has been proposed. Wang et al. [13] propose a visual secret-sharing scheme (VSSS) with (k, n)-threshold based on QR codes. In the processing of encoding QR code, the bits corresponding to shares ...
Data hiding by simple LSB substitution In this section, the general operations of data hiding by simple LSB substitution method is described. Let C be the original 8-bit grayscale cover-image of Mc×Nc pixels represented asC={xij|0⩽i<Mc,0⩽j<Nc,xij∈{0,1,…,255}}.M be the n-...
