In open network Encryption is used to transmit data securely. Each type of data has its own features, therefore to protect confidential image data from unauthorized access different techniques should be used. A framework is presented in this paper to evaluate image encryption schemes. A number of parameters such as correlation coefficient, information Entropy and a number of pixel change rate are used to quantify the security of encrypted images instead of visual inspection. Encryption efficiency analysis and security evaluation of some schemes like Zonal Transformation Matrix Method and Primitive Root Based Image Encryption schemes are presented. Experimental results demonstrate that the Zonal Transformation Matrix Method provides effective performance and security compared to primitive ischolar_main based encryption scheme.

With the fast development of data exchange in electronic system, safety of information is becoming more important in data storage and transmits. Because of commonly using images in industrial practice, it is very important to protect the confidential data from unauthorized access. This paper suggests that image encryption and decryption process based on block based encryption. The algorithms consider here are zonal based image encryption and primitive ischolar_main based image encryption. The zone based image encryption is working based on the principle of zonal transformation matrix, whereas primitive ischolar_main based image encryption is based on the principle of primitive ischolar_main theorem. The attribute considered for the comparative study are information entropy and average deviation analysis. Experimental results demonstrate that the zone based image encryption method provides effective performance compared to primitive ischolar_main based encryption method.

Due to the unlimited growth of Internet and communication technologies, the extensive use of images in diverse areas such as medical, military, science, engineering, art, entertainment, advertising, education has become unavoidable. With the increasing use of digital techniques for transmitting and storing images, the fundamental issue of protecting the confidentiality, integrity as well as the authenticity of images has become a major concern. This paper proposes a new encryption and decryption algorithm based on transformation matrix. According to this, there are two levels of process. In the first level the block matrix of size 3 x 3 is constructed using the secret key. In the second level, the zone of size 6 x 6 is constructed from the block matrix. The two levels are repeated to get the transformation matrix and is used for encryption purpose. The experimental results are compared with various image encryption algorithms.Keywords

Road transport is highly affecting the routine activities of the people due to over population and availability of poor resources. In order to utilize the precious time available in an efficient manner an Android App could be a solution. This paper aims in providing a dynamic time chart for the Public who rely on the bus transport facilities. In the proposed work the Android App continuously sends information regarding the location of the bus to the database linked with the APACHE server. The database also contains the distance and the location of the bus stop. The time taken to reach the destined bus stop is calculated using the database. On opening the webpage the public’s can select the bus stop and view the arrival time of the buses to the respective bus stop. By linking the app with the traffic monitoring system of that area an accurate arrival time of the buses could be predicted to suite the real time scenariosKeywords

Increasing power demand provokes the young minds to found alternative solution to generate power using various modes. Among the various method of conventional power generation, solar is a prominent energy source for generating power. But the availability of the same is possible only during the day time and is also affected by monsoon variations. An alternative effort to solve this problem is proposed in this paper using IR sensors. The IR sensor in a grid arrangement could be used for energizing the solar panel during the night time and even during the days of monsoon variations. This work analyzes the efficiency and driving capacity of the IR grid used for power generation. This paper also focuses on the alternatives to the IR sensor which is under the study for future development.Keywords
