The study of content-based image retrieval (CBIR) algorithms has been extensive due to the exponential rise in digital photo storage. Processing and storage resources are frequently heavily depleted in CBIR services. Thus, it makes sense to take use of the cloud server’s enormous capacity to manage CBIR services. However, privacy protection becomes a huge concern since there is a lack of confidence in the cloud server. In this paper, we provide an innovative outsourced CBIR technique based on the bag-of-encrypted-words (BOEW) concept. The picture is encrypted using three different techniques: color value replacement, block permutation, and intra-block pixel permutation. The local histograms are then calculated by the cloud server using the encrypted photo blocks. It can be useful to combine RSA cryptography with DWT, Huffman Coding, and steganography.

摘要

The study of content-based image retrieval (CBIR) algorithms has been extensive due to the exponential rise in digital photo storage. Processing and storage resources are frequently heavily depleted in CBIR services. Thus, it makes sense to take use of the cloud server’s enormous capacity to manage CBIR services. However, privacy protection becomes a huge concern since there is a lack of confidence in the cloud server. In this paper, we provide an innovative outsourced CBIR technique based on the bag-of-encrypted-words (BOEW) concept. The picture is encrypted using three different techniques: color value replacement, block permutation, and intra-block pixel permutation. The local histograms are then calculated by the cloud server using the encrypted photo blocks. It can be useful to combine RSA cryptography with DWT, Huffman Coding, and steganography.
