A system and a method are disclosed for tracking user activity with products in an environment. In an embodiment, a processor detects that a user has entered an environment, and responsively uniquely identifies the user. The processor determines that the user interacts with a product of a plurality of products within the environment, and responsively updates a profile of the user with indicia of the product. The processor determines whether the user is attempting to exit the environment, and, in response to determining that the user is attempting to exit the environment, prompts the user to confirm that the user intends to remove the product from the environment based on the updated profile. The processor receives input from the user confirming that the user intends to remove the product from the environment, and responsively further updates the profile based on the input.

A Method and apparatus for resilient Decoy Routing without conspiring Autonomous Systems by instead using a DHT routing table is described. In one embodiment of the present invention, there would exist a set of Decoy Routing Nodes which would be connected via a DHT's routing table. This would enable decoy routing nodes to not depend on a predefined list. Traditionally, Decoy Routing depends upon either a pre-configured list of computer systems to connect to or is wholly dependent upon BGP to happen to route to friendly Autonomous Systems that understand the true intent of the packet being routed. This method and apparatus solves these problems by providing a means to use a dynamic routing table, provided by a DHT to ensure that a packet can be delivered to computer systems that understand how to do decoy routing. This approach further ensures that the routing table being used is one that is kept up to date automatically as a function of the DHT providing the routing table. Further, the methodology described ensures that evading censorship, defending against TCP replay attacks, latency analysis, website fingerprinting, and denial of service (DoS) attacks are successfully executed.
