offline data synchronization using prioritization based speech authentication system

Abstract

Offline data synchronization is a technique used to design an application that works without an internet connection. In the proposed work, offline synchronization methods for Android have been enhanced along with the Security, Prioritization and Optimization in the data file. The synchronization process has to be first validated, and hence a speech recognition mechanism has been applied in the proposed solution. Speech authentication systems along with unique feature selection and classification techniques are applied for providing security. In addition to security, the proposed framework presents a set of cache memory which is updated when the user is online to optimize the synchronization process. The priority algorithm works according to user preferences. The files which are not in use for a long time are removed from the cache memory of the offline user and the files which are used by the user are often transferred to the cache automatically. The proposed work does not simply emphasize user access, but also offers a secure manner to handle the data. The proposed job also manages memory well so that the user does not find any hysteresis. The encryption time and the retrieval time for varied file sizes have also been measured using AES and DES. The proposed work measures accuracy of synchronization utilizing the ANN and Storage space consumption with or without using Storage Optimization algorithm.
