Patent ID: 7581244

Claim:
A network communication system comprising: a network server for selectively providing network access to soliciting network clients; and a client device for contacting said network server and soliciting network access; wherein: said network server is configured to respond to said client device soliciting network access by requesting authentication information from said client device, and responding to receipt of verified authentication information from said client device by generating a first access key code transmitted as a first issued key code embedded within an executable software code to said client device; said executable software code being effective for launching a client application on said client device and passing said first issued key code to said launched client application; said client application being effective for transmitting to said network server said first issue key code as a first returned key code along with a request for establishment of a communication session; said network server, upon receipt of a document submission or document request from said client device, responding to said first returned key code matching said first issued key code by destroying said first access key code, accepting the submitted document or document request, establishing a communication session with said client application, generating a second access key code unrelated to said first access key code, and transmitting said second access key code as a second issued key code to said client application.
