Secured Digital Image Sharing by using NVSS

Pramod Shimgekar ^[2] | Kishor Wane ^[2]

Abstract: Conventional visual secret sharing schemes hide secret images in the form of shares that are printed on transparencies and stored in a digital form. The generated shares appear as noise-like pixels, but it will stimulate suspicion and increase the interception risk during transmission of the generated shares. Hence, visual secret sharing schemes experience from a transmission risk problem for both the secret data image and for the participants who are involved in the sharing process. To tackle this problem, the proposed natural-image-based visual secret sharing scheme (NVSS scheme) shares secret images via various transporter media to protect the secret data image and the participants during the transmission phase. A very significant role is played by Encryption and decryption algorithms to transmit digital images securely from source to destination. Number of encryption and decryption algorithms is available in order to encrypt the task. The proposed analysis over the different sets of the image by using the three different Encryption and Decryption algorithms is performed. The comparison is made over the analysis made by using the different parameters such as PSNR value, Bi-Linear PSNR value, MSE (Mean Square Error) value, Elapsed time required or Encryption and Decryption process. Implementation and analysis of different selective image encryption and decryption technique is made in this paper by using Matlab.
