The present invention is drawn to an apparatus and method for providing secure network communication. Each node or computer on the network has a secure, intelligent network interface with a coprocessor that handles all network communication. The intelligent network interface can be built into a network interface card (NIC) or be a separate box between each machine and the network. The intelligent network interface encrypts outgoing packets and decrypts incoming packets from the network based on a key and algorithm managed by a centralized management console (CMC) on the network. The intelligent network interface can also be configured by the CMC with dynamically distributed code to perform authentication functions, protocol translations, single sign-on functions, multi-level firewall functions, distinguished-name based firewall functions, centralized user management functions, machine diagnostics, proxy functions, fault tolerance functions, centralized patching functions, Web-filtering functions, virus-scanning functions, auditing functions, and gateway intrusion detection functions.

A hash function used for content addressing is different from the hash function used for content verification. Adding a file to a database involves storing both hash function values in a table as pair. Verifying the integrity of a file believed to be a duplicate in a database, or when retrieving a file, makes use of the verification hash function. Files can be continuously checked. A multi-level database can be used. A second hash function can be added to an existing system. A verification hash function can be upgraded and more than one content verification hash function can be used. In a variation, a random number generator is used instead of a hash function for content addressing; the verification hash function is also used. Files addressed using a random number are added or retrieved from a database and their verification hash values are checked. Time stamps and digital signatures are used for security.

A method of directly modifying ray tracing samples generated by a ray tracing renderer. Modifications to samples may be made after rendering and before rasterizing, in contrast to typical compositing workflows that manipulate pixels of a rasterized image. Modifications may be based on user input. Rasterization may be performed afterwards at any desired resolutions, for example to adapt to different displays. Samples may be tagged with object identities, facilitating object selection without the need for object masks. Pseudo-random ray patterns typically used by renderers may be supported directly. Many operations may be performed directly on samples, including color changes, object repositioning, and merging of samples from different scenes. Secure samples with scrambled ray directions may be modified directly. Modified samples may be compressed for storage or transmission, and may be streamed to receiving devices that rasterize the samples for display, possibly after decompressing or decrypting the received streams.

Secure rendering system that creates ray tracing samples with obfuscated positions, so that images can only be viewed by an authorized consumer able to recover the sample positions. Obfuscation of ray directions is integrated into the rendering process, for example by incorporating encryption into a lens shader. The rendering system never stores or transmits an image without obfuscating positions, so even the rendering system cannot see the image it is rendering. Embodiments may use public key cryptography, so that encryption of sample positions is done with a public key, and only the owner of the secret private key can view the rendered image. Since keys are asymmetric, the rendering system cannot decrypt the obfuscated samples. Piracy of rendered images is therefore mitigated. Some compositing operations may be performed on the secure rendering output prior to decrypting sample positions; for example, colors may be modified globally or for selected objects.
