A Trinity Approach for Secure Image Access and Retrieval in Cloud

Images plays an important role in human’s day to day life and it consumes much more space for storage rather than other formats. Hence, the need for cloud storage outsourcing arises. The Privacy of user and transfer of images in the network is the main concern. For privacy-preservation purposes, sensitive images, such as medical and personal images are needed to be encrypted before outsourcing, which makes the CBIR technique on plaintext realm to be inoperative. To ensure user privacy, a keyword based technique is introduced to provide individuality for the users. User validation for accessing their images from the cloud is provided by generating an OTP. The cryptography and segmentation techniques are upholding image security during transfer. Additionally, the illicit publication of user images is recognized with the help of watermark extraction. Keyword: User Keyword, One Time Password (OTP), AES 128 bit Encryption/Decryption, Watermark, Segmentation, Least Significant Bit (LSB) Steganography, and Locality Sensitive Hashing (LSH).
