摘要：Internet communication has become the essential part of the infrastructure of today’s world. The informationcommunicated in various forms and this information is used in many applications which are in a secrete format. Securityis one of the most important factors for transferring different types of important documents. Internet is one of the mostimportant media which is used to transfer documents. This is used in bank transfers, email communications, credit cardpurchases on large number of daily email and military application. But in reality the internet is not a secure form. So weare suggesting VC that is visual cryptography method which is simple, fast and provide security while sharing secretesdocuments over the internet. These documents are presented in a bit map format file, and extend it into two or moreencoded file shares which can be transferred to the receiver in a cover image using BPCS that is Bit Plane ComplexitySegmentation technology through electronic mail. The Bit Plane Complexity Segmentation allows hiding large secretinformation into cover image. This cover images are selected for analysis and according to the threshold value it willincrease the complexity of each segment to verify the changes occurred in the original image. And data will be stored athigher complexity. Steganography is technique of data hiding. Steganography is a technique in which secret data is hiddeninto vessel image. All other techniques have limited data hiding Capacity and other technique can hide up to 15% of dataamount of vessel image. But hiding capacity of steganographic technique is up to 50 –60%. This technique is called BitPlane Complexity Segmentation (BPCS) Steganography. Therefore, the final image can be obtained only when the numberof shares is combined together at receiving side. Thus a combined use of VC and BPCS technology provides data securityto all forms of documents during transfer over internet.
