Abstract: Methods and systems for performing electronic commerce using mutating identifiers. One method can include encrypting buyer transaction data with a first mutating identifier, transmitting the buyer transaction data to an authenticator device, decrypting the buyer transaction data, generating a payment request, encrypting the payment request with a third mutating identifier, and transmitting the payment request to a payment authenticator device.

Abstract: A multiple party system for distributing content. In one embodiment, four parties are involved in the system: a consumer, a service provider, an authenticator, and a content provider. The distribution of content from the content provider to the consumer is carried out using a predefined protocol, mutating IDs, watermarks, and licenses. The authenticator controls the distribution of mutating IDs, verifies the identity of one or more participating parties, and provides tracking information for mapping service providers and consumers to particular, possibly watermarked, content items.

Abstract: Methods and systems of encrypting data. One method includes establishing data that includes discoverable or “white” data and undiscoverable or “black” data. Black data is generally unrecognizable. For example, it may be random data. White data generally has recognizable content or is transmitted in a recognizable format. A first key and a second key are created or established, such that the second key is substantially underivable from the first key. The discoverable or white data is encrypted with the first key and the undiscoverable or black data is encrypted with the second key. In subsequent communications or transactions, at least one of the first key and the second key is mutated.
