The present invention provides a system and method for server side control of storage and momentary access to restricted material from a remote client side computer. The method comprises the following steps: sending an identification and selection code from a client to a server over a connection between the client and the server; sending selected digital materials in encrypted format from the server to the client in response to the reception of the identification and selection code; sending the information code and an initiation request from the client to the server; generating a decryption key at said server for decryption of the selected digital materials in response of the reception of the information code and an initiation request; executing a control programme in the client; sending the decryption key from the server to the client; and accessing the selected digital materials at the client under control of the control programme using the decryption key, and wherein the control programme is designed to regulate the display of a service connected with the selected digital materials. The present invention may as well provide a beneficial model for advance download and timed access of any digital material, where real time online access may be difficult due to bandwidth requirements. |
