Abstract

A barcode is an optimal machine-readable representation of data relating to the object to which it is attached. Encoding data using barcodes enables a significant decrease of work in comparison with the amount of work involved when data is entered manually. In this paper, a high capacity color two dimensional barcode uses the colors to increase the barcode data density. This is proposed by encoding data in individual color channels. Data encoded in cyan, magenta, and yellow channels are estimated from red, green, and blue sensor channels of a scanner, respectively. Data is encoded by modulating the orientation of elliptically shaped dots. The orientation based data encoding provides beneficial robustness against printer and scanner tone variations. By encoding data in individual color channels, the capacity of color barcode is increased. The color interferences are avoided by using error correction methodology. The security is involved through modify extraction of geometric distortion signature from a printed barcode, which can be used to identify the type of source printer. User can view the data from the color barcode by using their mobile phones.

Abstract

This paper proposes to create a Security measures in an organisation using Android based mobile device to provide security alert and prevention system. The main objective is to provide the physical security for the employees, because employees are the major asset of an organization. This security mechanism is also used to prevent the loss of physical assets of an organization. This Security mechanism includes common alert system for individuals, ability to search for emergency request team, emergency path search, fire extinguisher search and calling to an emergency team on easy access that can be accessed from anywhere and around the organization’s environment. If any unexpected accident happens in an organization, the administrator triggers the alarm to employees, so the persons inside the building may know the actual reason of the alarm. This alarm is not triggered to the entire department in an organization. The alarm is triggered only to the departments which are in danger zone. Employee can also alert administrator by uploading the images to the server which will handle Short Message Service and mailing functionalities. Client can also update the server by sending the information regarding the current location and about the current situation. This type of alert system reduces the ambiguity in case of emergency situation. This alert system makes employee feel safe and ease during the unexpected situation happening inside the organization. If any unusual things happening in the outside of the organization, administrator immediately sends the information to the clients in the form Short Message Services. Employees in the one region can be alerted from any other region if the organization and the organization’s employees is equipped with this security and alert system.
