Effect Of Blob And String Data Type On Time And Space Consumption In Recognition Based Image Authentication Scheme
Zeeshan I. Khan , Vijaya K. Shandilya
Abstract
Authentication is the process of recognizing a user’s identity on any system or network. The authentication process always runs at the start of the application to authorize the user. Recognition based image authentication scheme (RBIAS) is one of popular method of image authentication scheme in which user can select its password in the form of images to remember it easily. A binary large object (BLOB) is a collection of binary data stored as a single entity. Blob data type is typically used to store images, audio or other multimedia objects. In this paper, we have given the comparison of time and space complexity between blob data type and string data type at the time of image storage and verification in recognition based image authentication scheme. The results are analyzed by implementing both (blob and string) data type techniques and given a productive output showing which data type should be used while storing images in image authen-tication scheme
