In some embodiments, techniques for modifying a profile may include receiving a first profile data associated with a first user, associating the first profile data with a profile associated with the first user, receiving a second profile data from a second user that is a result of a modification of the profile data, associating the second profile data with the profile, and providing the profile to a third user, wherein the profile includes the second profile data and an indication that the profile has been modified, which includes an indication that the second user is responsible for the modification.
Abstract:
The detection system monitors WiFi wireless communications at a wireless device and detects a probe request associated with a location. The WiFi device may be a dedicated presence detection device or may offer access to internet and other services as a WiFi access point. A device identifier associated with the originating device may be a component of the probe request. Using the device identifier, the system can detect the presence of a consumer at the location associated with the wireless communications device and transmit information to the consumer based upon the device identifier.
Abstract:
In some embodiments, techniques for pricing may include detecting a visitor at an e-commerce site, determining that an item offered for sale at the e-commerce site is of potential interest to the visitor, detecting another e-commerce site at which the user has viewed the item, determining a historical price, wherein the historical price is associated with a web page, wherein the web page offered the item at the other e-commerce site, calculating an offering price, wherein the offering price is based on the historical price, offering the item to the visitor at the offering price, and selling the item to the visitor at the offering price.
Abstract:
In some embodiments, a technique for logging an item encountered by a mobile device comprises automatically detecting an item in an uncontrolled environment, extracting an identity associated with the item, logging an encounter, wherein the encounter includes the identity, and deleting the encounter after a predetermined period of time has elapsed, wherein the encounter is not marked as relevant.
Abstract:
Distributed distribution of patches and other updates is disclosed. A request for an update is received. In some embodiments it is determined whether the source of the request will serve as a redistribution point. If the source will serve as a redistribution point, a redistribution identifier associated with the source is stored. In some embodiments it is determined whether the update will be provided to the source of the request directly, e.g., from a (more) primary source of the update, such as a source that received the request, or indirectly, e.g., from a secondary source such as a host to which a (more) primary source provided the update previously. The request is serviced either directly or indirectly, in accordance with the determination.
Abstract:
The presentment and redemption system offers discounts directly to consumers through their mobile phones. The discounts are based upon the user of the mobile phone meeting a targeting criterion and the discounts are determined using the targeting criterion. Mobile phone users that do not meet the targeting criterion are not eligible for the discount. Because the discounts can be targeted to each individual consumer, there can be a better correlation between consumers' interests and the transmitted discounts.
Abstract:
Techniques for providing a digital frequency card are disclosed. A digital frequency card provides an offer or reward upon completion of a prescribed set of one or more actions. In some embodiments, in response to receiving an indication of an occurrence of an action from a set of one or more prescribed actions associated with a digital frequency card of a user, information associated with the digital frequency card stored with respect to a user account of the user is automatically updated to reflect the occurrence of the action, and the user is automatically provided a current status of the digital frequency card.
