Abstract
Ubiquitous Computing uses mobile phones or tiny devices for application development with sensors embedded in mobile phones. The information generated by these devices is a big task in collection and storage. For further, the data transmission to the intended destination is delay tolerant. In this paper, we made an attempt to propose a new security algorithm for providing security to Pervasive Computing Environment (PCE) system using Public-key Encryption (PKE) algorithm, Bio-metric Security (BS) algorithm and Visual Cryptography Scheme (VCS) algorithm. In the proposed PCE monitoring system it automates various home appliances using VCS and also provides security against intrusion using Zigbee IEEE 802.15.4 based Sensor Network, GSM and Wi-Fi networks are embedded through a standard Home gateway.
