Users may have various login ids it will be hard to remember their passwords and alphanumeric passwords are difficult to remember. So the graphical password is one of a secure solution. Some threats of Internet security are spyware and shoulder-surfing attacks. This paper presents a new scheme for a graphical password that uses images that are unexplainable and have larger password space. The proposed scheme is also resistant to spyware and shoulder-surfing attacks. Security always remains a constraint when we talk about the sharing of any information or document. For enhancing the security, here we have first encrypted the image then this encrypted image is used as password, so the password will be hard to guess and much secure from the attack to guess the password. One of the most challenging issues in data sharing systems is the enforcement of access policies and the support of policy updates. The solution to this issue is Ciphertext policy attribute-based encryption (CP-ABE). Ciphertext–Attribute-Based Encryption scheme enables an encryptor to define the attribute set over a universe of attributes that a decryptor needs to possess in order to decrypt the ciphertext, and enforce it on the contents. Thus, every user needs a different set of attributes to decrypt different pieces of data. It is proposed to use the CP-ABE scheme to improve security and efficiency in attribute-based multimedia data sharing. The proposed multimedia data sharing system includes Key Generation Center, Data Owner, Data User, Data Storing Center system entities that help to share image securely using CP-ABE scheme. Here, specifically focus is on sharing the image in ‘.jpg’ format.
