A Protected File Access Mechanism Using Visual Cryptography

S. Rajkumar, B.V. Baiju and Sruthi Chandrasekaran

In this era Cloud Computing has been used widely to bring more distributed data and resources together. The client can easily access the information from anywhere via internet at any time. As many data is introduced in each day, the insurance of information protection, delicate information typically needs to be scrambled before redistributing, which makes compelling information usage a difficult assignment. Here comes the need of client to protect the data that they store and accessing it wisely. The proposed system uses Advanced Encryption System (AES) for secure file uploading. Cloud provider upload the user file with secured image, that image should be splitting into two images like source and key image by using BVCS (Binocular Visual Cryptography schemes algorithm. Then, the key image and the password will be sent to the particular user and the necessary file can then be downloaded. The password is generated which is then splited into source image and key image and they are stored to the user and cloud server. Now the user has to send the key image to the cloud for accessing the files. The cloud matches the key image with the source image it already has. When both matches the file can be downloaded.
