A method of authenticating a user access to network stations is disclosed. Users of the new authentication system do not need to input passwords to gain access to the network stations for on-line transactions, as the authentication job is handled by the authentication server and the net entry apparatus through a host computer. A token is generated dynamically and sent to the application server to which the user intends to gain access, and the verification process is then activated between the authentication server and the application server, which then retrieves a symmetrical copy of the token to compare with the token passed from the application server. If both tokens match up, the user ID has passed the security check. Users are freed from having to memorize different user IDs and passwords to operate many network accounts, with no risk of losing network account numbers and passwords.

A method of an efficient adaptive mode selection for H.264 / AVC-coded video delivery in burst-packet-loss networks to generate the image data of the missing macroblocks in the decoded current frame by using the information related to the spatial redundancy in the same frame and the temporal redundancy in the inter frames is disclosed. The method first employs the Intra High-Speed Spatial Error Concealment (SEC) method for the initial frame.
