Abstract: A test person is compared to a reference person by comparing detailed information regarding the configuration, capabilities and usage of computers—such as installed hardware devices, makes and models and firmware versions of such hardware devices, installed software, versions of installed software, and usage logs—used by the respective individuals. In effect, each person's computer is considered a proxy for the person herself, representing countless purchasing, maintenance, pastime choices in the configuration and use of a thoroughly complex personal and professional tool.

Abstract: Energy resource dispensing terminals can be added one-at-a-time to a wide area resource distribution system very easily where needed as needed. Each terminal can dispense any of a number of types of energy resources such as electricity, compressed hydrogen, compressed air, and waste vegetable oil. The energy dispensing terminal includes a terminal control computer that interacts with customer computing devices, such as personal, portable computing devices or onboard computers installed in vehicles to effect negotiation and fulfillment of energy resource purchase transactions. A resource sharing server facilitates such transactions by maintaining and verifying identities of customers and sellers along with financial account information such that a registered customer can purchase energy resources from any seller registered with the same resource sharing server.

Abstract: A local area advertising server limits distribution of advertisements to computing devices, preferably mobile computing devices, that are carried by people likely to be in close physical proximity to a store or location to which the advertisements pertain and likely to be currently engaged in activities relevant to the advertisements. Advertisements from a specific store can be delivered immediately through the Internet to people physically inside the store. Computing devices coupled to a local area network located in or near a store or other location are presumed to be physically in or very near the store or location. By associating advertisements with local area networks to which they pertain, only advertisements associated with the local area network to which the computing device is connected are sent to the computing device.

Abstract: Reputations of anonymous sources of information are managed by associating the reputations with devices from which the information is received rather than from the human individuals using those devices. The devices are recognized using a one-way identifier, such as a digital fingerprint, such that the source device cannot be used to readily identify the source device or its user(s) but all items of information received from the same source device can be readily recognized. Feedback from other devices is accumulated and used to assess trustworthiness of the source device and reputation data representing such trustworthiness is published along with the information received from the source device.

Abstract: A method for near field authentication of sources using an audio transceiver computing device includes scanning a plurality of predetermined frequencies for a free frequency, selecting the free frequency from the plurality of predetermined frequencies, generating a periodic enclosed content message, generating a modulated carrier wave representing the periodic enclosed content message, and transmitting the modulated carrier wave at the free frequency. A method for near field authentication of sources using a microphone input of a receiving computing device includes scanning a plurality of predetermined frequencies to detect a signal using the microphone input, verifying, responsive to detecting the signal, that the signal includes at least one enclosed content message, and extracting a content from the enclosed content message.

Abstract: Personal information on a networked client computer is used by a server from which the device has requested information to infer demographic characteristics of the user of the client computer in order to add customized content to the requested information. The personal information provided to the server is gathered from the use of network browser software by the client computer and includes cookies, history and bookmarks. Inferring demographic characteristics of the user involves application of predetermined demographics inference rules stored by the server to the personal information provided by the client.

Abstract: A method for implementing zone-restricted behavior of a computing device includes identifying wireless access points using the computing device, determining a number of authorized wireless access points from the wireless access points identified by the computing device, determining that the computing device is located within a restricted access zone when the number of authorized wireless access points identified by the computing device exceeds a predetermined threshold of authorized wireless access points identified, and enabling a zone mode of the computing device when the computing device is determined to be located within the restricted access zone.
