Due to the extensive availability of wireless internet connectivity and low cost light weight mobile devices, an omnipresent customizable service is not a vision anymore. With enhanced wireless connectivity, the handheld mobile devices (PDA, smart phone, cell phone, etc.) can act as a digital personal secretary, being employed in all aspects of life for the purposes ranging from accessing wide range of information to performing various types of activities with greater ease and comfort. If this type of service can be made a reality, it can be used by different types of users in different fields such as education, tourism, shopping or business, at any time and at any place. Here we present Ubiquitous Secretary, which is designed and developed to accomplish the above objectives. Ubiquitous computing applications developed so far are all independent and rich in their own domains but they suffer from the problem of non-inter operability and non scalability. Ubiquitous Secretary is developed upon the web services architecture that easily solves the interoperability and adaptability problem between different ubiquitous computing applications. We developed a prototype and presented how the implementation of the prototype satisfies the characteristics and features of Web Service based architecture.
