A Personal Digital Key Digital Content Security System (PDK-DCSS) is used to protect computers from unauthorized use and protect the digital content stored on computers from being wrongfully accessed, copied, and / or distributed. The basic components of the PDK-DCSS are (1) a standard hard drive device, with the addition of a PDK Receiver / Decoder Circuit (PDK-RDC) optionally integrated into the hard drive's controller, and (2) a PDK-Key associated with the PDK-RDC. The PDK-Key and RDC technology is utilized to provide two categories of protection: (1) hard drive access control for providing Drive-Level and Sector-Level protection and (2) operating system-level independent file protection for providing File-Level and Network-Level protection.

The present invention relates to a method and a system for protecting data in a computer network. A device is placed on a network edge in such a way, that all outgoing data has to pass through it. Separately, a set of data that is not allowed to leave the network is defined and stored in a secure form (typically, one way hash). The device determines the network protocol, file type, transforms and normalizes the passing data, and seeks the presence of the data from the defined set. If a threshold amount of the protected data is present, the device takes one of the following actions: block, alert, log, redact, store, redirect, encrypt, notify sender.

The invention provides a network identity authentication method based on the biological characteristic authentication of a third party on the Internet. The biological characteristics (fingerprint, human face, iris, lip membrane and so on) are used as the identity identification of the user, the user can obtain an authentication request from the third party by submitting the biological characteristic codes through a client terminal widget provided by the third party, the identity authentication is carried out through the request password process and the matching algorithm, the Internet identity authentication can be carried out through a fully cooperative website or an application program provided by a cooperative network in a self-help mode, the third party provides request interfaces containing the registration, verification, reset of the biological characteristics, binding information,etc., the third party needs not to know the name of the user in the cooperative website or the application program provided by the cooperative network, thus avoiding to obtain the other information of the user in the cooperative website or the application program provided by the cooperative network, the reliability at the service terminal and the communication safety among the three parties can be guaranteed through the complete active service request of the cooperative website or the application program provided by the cooperative network, the Cookie, SSL, multi-encryption, digital signature of the widget, user-defined words or pictures,etc.

A method and system are directed towards enabling content security in a distributed environment. The system includes a data store for content associated with an application that may be tagged as exclusively memory resident at a client. The content may also be encrypted and digitally signed. When an authenticated client requests the content, it is provided at a constrained rate that enables a portion of the content to start execution on the client before the application associated with the content is completely downloaded. Additional portions of the content are provided to the client when the additional portions are required for execution by the application.
