This paper addresses the problem of image retrieval from an encrypted database, where data confidentiality is preserved both in the storage and retrieval process. The paper focuses on image feature protection techniques which enable similarity comparison among protected features. By utilizing both signal processing and cryptographic techniques, three schemes are investigated and compared, including bitplane randomization, random projection, and randomized unary encoding. Experimental results show that secure image retrieval can achieve comparable retrieval performance to conventional image retrieval techniques without revealing information about image content. This work enriches the area of secure information retrieval and can find applications in secure online services for images and videos.

“…Images are different from text. Only recently, secure text document search in the encrypted domain [8], [9] has been extended to secure multimedia data search [10], [11]. Although traditional cryptosystems may be used to encrypt images directly, it is not a good idea for two reasons.…”

Security in the cloud is the top most concern. To achieve trust and preserve the privacy of data stored in third-party cloud storage has emerged as a key research area. To achieve this, several different techniques have been proposed based on cryptography. Secret sharing schemes and chaos based encryption have also been considered to address these issues of trust and privacy by various researchers. In this paper, we are proposing a new scheme to encrypt the private and sensitive images of users in the third party storage named as "Securing images in cloud using hyper chaos with user authentication" to solve the problem of authenticating users. Chaos based encryption with image captcha authentication using VCS is a major advantage of this scheme. Chaos based encryption is a very secure method for encryption. Many researchers have used the above technique but user authentication or authorization is not mentioned in their schemes. To increase more security we have included the authentication in the scheme. In this paper the authentication process is explored in depth and only the overview of encryption process is given. For securing the authentication logistic map is used to divide and shuffle the original image captcha into many blocks. The use of visual cryptography technique is explored to preserve the privacy of image captcha. Part of the image share will be kept with the image owner such that the original image captcha can be revealed only when both (user, owner) of the shares are simultaneously available. The individual share images do not reveal the identity of the original image captcha. Once the original image captcha is revealed after merging different shares, the user will be considered as authenticated user. Then only the encrypted key for the images will be transferred to the user. Dynamically generating the Captcha image by the system is one of the major advantage of the system.

“…The symmetric encryption of the actual data, S(M (j) , Lj) is efficient in terms of storage and protocol overhead as it does not cause ciphertext expansion. Such a strategy of searching for matches in a lower dimensional space, while encrypting the media file separately has also been applied in media retrieval schemes based on order-preserving encryption [16].…”

We are specifically concerned with scenarios in which multimedia data is stored once on the server and the same data is queried by multiple parties. We propose a framework for privacy preserving querying, in which encryption is performed only once, and the ciphertexts are stored on a database server. Rather than using public-key homomorphic cryptosystems, the parties querying the database first derive an "attribute" from their query signal. They can decrypt the server's ciphertext only if their attribute satisfies a specified mathematical condition. This queryspecific decryption capability makes attribute based cryptography a vital addition to the secure signal processor's toolkit. We give an example of a construction for privacy preserving querying, in which a client can privately retrieve an image from the server if attribute vectors extracted from the server's and client's images are close enough in Euclidean distance.
