摘要

The Reversible Data Hiding (RHD) is the one of the useful technologies to solve the issues in multimedia security. The lossless data hiding is the most promising data technique; it needs to provide the complete data with a cover media after embedded data is retrieved. For solving this issue, reversible data masking method like Versatile Speed Correlation Vector (VFCVQ) compressed images have been proposed. The two main concerns about data masking are the ability to hide and stereo image quality. The higher efficiency of the VFCVQ images sends more confidential data. A VFCVQ compressed image means it will store the secret data with the original image size, and it will keep avoiding the unwanted attention of the compressed image. The scheme proposed an RHD method based on the concept of a VFCVQ. The proposed coding system uses a specific value to determine the ability to embed confidential data into an image and creates a VFCVQ encoded image or output compressed code stream. Progression of integrating a sensitive data with an original VFCVQ encoded images will be retrieved when output is needed. The proposed method will be implemented to process the secret data using three ways progress which is typically identical in a VFCVQ encoded image; initially the system obtained four-layer connection for embedding the data bit, second it uses the Hierarchical Code-Code Mapping (HSCM) reconstruction to match the first word's encoded-word in image, Finally it will calculate the difference between the new code of the two adjacent blocks, After progressing all of this procedure the encryption of secret bit data values are analyses with each compressed output block. The proposed system is executed in the MATLAB simulation environment; the result of an output data is compared with the proposed methods with previous RHD techniques. The performance analysis of the proposed RHD techniques provides an efficient in terms of like compression ratio 39.2 (%), embedding rate 1.50 (kb), PSNR rate 38.9 (dB) compared with conventional schemes.
