Searching Text on 2D Image Over Encrypted Cloud Data using OCR

摘要

In this paper, we propose a scheme to search a text keyword on 2D image over encrypted cloud data using OCR conversion. Nowadays, Storage as a Service (SaaS) has become a reliable method of storing the individual and organizations huge volumes of confidential data in the cloud server. The data stored on the cloud may be a text file with normal plain text and an image file that contains text or scanned image of a text file. It is also an essential to store this kind of image document into cloud server and provide security to it. There are many traditional schemes to search keyword over cloud data and retrieve the required files. The scheme should also support keyword search over image documents when it is stored on the cloud. In this proposed scheme, we are using OCR technique for image document to text file conversion.
