Described herein is a method and apparatus to randomize instruction sets, memory registers, and pointers to increase computer security by increasing resource commitment requirements for malicious software, malicious computer users, or reverse engineers to understand the meaning of the new instruction sets, memory registers, and pointers.

Method and apparatus for randomizing computer instruction sets, memory registers and pointers

The present invention allows an on-line user to specify the name by which that user is known when communicating with other target users, regardless of the name under which the sending user is currently logged-in. The invention also provides a mechanism to block messages from sending parties that are not willing to divulge their real identity.

Preferred name presentation in online environments

An avatar in a virtual world is provided with credentials for access to various parts of the virtual world by embedding information derived from avatar identification and authorized credential information in the form of a graphic image associated with the avatar. The embedded information is preferably encrypted.

Identity verification in virtual worlds using encoded data

A system and method provides secure channels for communication in a virtual universe by employing a packet interception layer for incoming and outgoing data packets. A data path is defined and is sequentially encrypted with the public keys of servers in the path. Decryption and identification of the next server occurs in a sequential manner in which the path is known only to the sender.
