Image Encryption and Decryption for Real time Applications

Introduction

 

The issues addressed in this research are possibilities to achieve efficiency measured in terms of level of security, compression rate and processing time, by using partial image encryption. The objectives of this research are as follows:

 

•  To reduce the amount of data to encrypt while achieving a satisfactory and low-cost protection

•  Image encryption applied in the field of secure information transmission and secured data storage

•  The implementation of partial image encryption suitable for the real time applications like image encryption for medical, image encryption for satellite among others

•  The development and performance of a unique partial image encryption based on the percentage of encryption

Achievements

 

In this project work a quicker image encryption is proposed. Here we are implementing the partial image encryption using pixel scrambling technique to reduce the time required for encryption and decryption, this makes the encryption faster and reduces the time complexity. The security of this project work depends on pixel scrambling technique. Since there are many possibilities of pixel scrambling and random key generator, hackers will find it difficult to correctly guess all random strategies at the same time. Thus, the security is enhanced. The experimental results show that this method is effective to scramble the image and can provide high security.
