CHIEF ARCHITECT

ROLE: Project Manager, Architect

· Security - developed a solution for security and privacy in web application. It’s designed to be superior to conventional https and doesn’t need certification. Each user has a unique service channel all for himself with the server. The service channel is created during sign up and can be changed at any time. The security is robust and designed for a collaborative environment. Each collaborator or user has its own private key and not shared. It’s public key too is shared with main server alone and none other. Main server plays the role for the exchange of Symmetric keys between two collaborators and it signs off. Collaborators then exchange information during a session that can’t be interpreted by any one – even Main server. New algorithm has been devised for symmetric key generation that’s very fast and arbitrarily long. Encryption algorithm is Stream Cipher that too it is different in each invocation. ‘Sign up’ cannot be done under program control. User password is never sent from client in any form, and not stored in server. Client side object retrieves private messages and makes it available to JavaScript for incorporation within web document. Prototype in C++ is ready. Server side deployment was done using IIS 5 that's translated to COM objects, Java2 applets and RMI EJB using WebSphere AS2 and Java Web Server. IDE used included the following: VS 6, Forte 3, VisualAge 3 in Windows NT/ME

· Directory Services – Engaged in testing and evaluation of Java LDAP, eDirectory, Active Directory in web environment (WebSphere, IIS, TomCat) for development of enterprise wise user authentication system.

Responsibility: Architect, developer, sole contributor, and performance analysis

A Short Note on Security, Privacy and Encryption

Collaborative Platform for Healthcare

· Designed/developed a web based distributed document management system for the healthcare industry. This is a collaborative platform for the healthcare industry. Patients, practitioners, medical service providers, diagnostic centers, plan purchasers and health plan providers may become participating users and can communicate with each other at the P2P level. It implements instant messaging system for transferring message, document or document request. Collaborating servers could be any – IIS, Apache, WebSphere, or even, Personal Web Server etc. Authentication is only done in the central system implemented using IIS. Documents remain in the web servers of the participating user. It’s possible to search extensively for a patient, PCP, or document owned by any user. After locating a document, message may be sent instantly to the owner to release the same for access for limited time period. It’s also possible to capture all information related to patients – comments, notes, diagnostic reports, observations etc. It’s also possible to assign or remove consultants to a patient by PCP. PCP may allow limited access of patient information to consultants to a patient

Technology used: Windows NT, IIS 4/5, WebSphere 4, JavaScript, Java AWT and Swing, XML, XSL, XSD, WASD, MQSeries, VB Script, ADO 2, C/C++, SQL Server 7, ASP.NET, and Perl 5.6
