Security Enhancement using Image Hotspot with Hidden Privacy-Cipher text Policy-Attribute Based Encryption

Cloud computing is one of the developing fields for the automation and maintenance of several organizations. It increases the flexibility of the applications and has improved their efficiency. Due to this, a greater number of clients opt for cloud computing. Though it has several advantages in terms of maintenance and functioning of the applications, there is always the issue of data security and reliability. Various research works have concentrated on the security aspect of cloud computing and have proposed different protocols and algorithms to provide the user with the necessary security. However, these security solutions are primarily software-based and lack a basic architecture for protecting the data from malicious attacks. With the development of cryptography and other encryption models, it is difficult for attackers to decrypt the data and provide the necessary solution. This paper uses these advancements to provide a better security model that uses attribute-based encryption to protect user data. The cipher text policy is also used as a standard for this encryption process, and the user is given full control over his data. The file uploading is protected using the HP-CP-ABE method for secured file uploading. The authority center is maintained to authenticate the users in the system. And finally, an image shield security system is used to secure the users’ login. And finally, an OTP verification process is for approving the user. The proposed security model provides a foolproof mechanism to safeguard user security by providing security at different levels. The efficiency of the proposed system is compared with various existing ones, and the usability of the model is validated. The validation clearly shows that the proposed model provides better security than the existing ones.
