Abstract: In some embodiments, techniques for computer security comprise receiving an email message; determining a sender of the email message; determining whether the sender of the email message is trusted, wherein determining whether the sender of the email message is trusted includes determining whether the sender of the email message is associated with a whitelist; retrieving domain-related information by performing a DNS query on a domain associated with the sender; based at least in part on the domain-related information, determining whether the sender of the email message is verified; determining whether the sender is both trusted and verified; and when it is determined that the sender is both trusted and verified, treating the email message as trustworthy, wherein treating the email message as trustworthy includes bypassing a classifier.

Abstract: A system to control an electrical device, such as a lighting component or set of components. The system includes a set of connection lines, a power control module and a load interface component. The power control module is responsive to an alternating current source being connected to one of a first connection line and a second connection line to provide a regulated voltage signal output. A load interface component receives the regulated voltage signal output to control the electrical device.

Abstract: A home device controller can include one or more touch grooves, a touch slider operatively coupled to each of the one or more touch grooves, and one or more processors. The processor(s) can receive signals from each touch sensor, each signal corresponding to a touch gesture performed by a user interacting with the one or more touch grooves. The processor(s) can generate control commands executable by a home device based at least in part on the signals, and transmit the control commands to the home device for execution.

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.

Abstract: The transmission system transmits an encrypted identifier ultrasonically in an open-air environment using an ultrasonic transmitter. The ultrasonic identifier is associated with a location, which may be a store or a department within a store, and may be received by a microphone on a mobile phone. The identifier may be used to infer presence of the mobile phone user at the location associated with the identifier. The transmitter may include an ultrasonic transducer. The system may further provide a reward, responsive to inferring presence at the location.

Abstract: Various presence detection techniques are disclosed. In some embodiments, a system comprises a signal generator configured to generate a signal that includes a plurality of selected frequencies that are selected from among a set of candidate frequencies, wherein inclusion or exclusion of each candidate frequency in the signal encodes a bit of information and wherein the encoded information comprises a store identifier that identifies a retail store; and a transmitter configured to transmit the signal within the retail store; wherein presence of a device in the retail store is determined in response to reception of the signal at the device and extraction of the store identifier from the received signal by decoding the received signal.

Abstract: In some embodiments, techniques for computer security comprise parsing an electronic document; determining that a first element of the electronic document specifies immutability of a second element of the electronic document; setting an immutability indicator associated with the second element of the electronic document; receiving a request to modify the second element of the electronic document; determining that the immutability indicator associated with the second element of the electronic document is set; and responsive to determining that the immutability indicator associated with the second element of the electronic document is set, preventing the second element of the electronic document from being modified.

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: The optimization system monitors a mobile phone user's behavior in response to an offer for a reward and determines a good level for a product promotion. The determination may be made based upon the user's current response, past response patterns to various reward levels or a correlation between a user's behavior and the behavior corresponding to a class of users. The system can determine an offer level that maximizes the return on the profit or revenue from a potential purchase for which the offer applies.

Abstract: In some embodiments a system is provided, comprising a playback device, configured to play a piece of multimedia content, stop playing the piece of multimedia content, wherein the playing of the piece of multimedia content is stopped at a first point, connect to a server, and synchronize information relating to the first point to the server; the server, configured to save the information relating to the first point in a profile associated with an individual user, connect to a recipient device, and synchronize the information relating to the first point to a recipient device; the recipient device, configured to play the piece of multimedia content, wherein playing the piece of multimedia content on the recipient device starts from a second point related to the first point at which the playing of the piece of multimedia content on the playback device is stopped.

Abstract: In some embodiments, techniques for data security may include encoding and decoding unreadably encoded data, such as data encrypted with a public key or tokenized.

Abstract: Analyzing routing information to identify and intercept unauthorized, unwanted, and/or otherwise malicious communications is disclosed. In some embodiments, routing information associated with a message currently being processed is checked against corresponding information associated with a message from the same source that was processed previously. In some embodiments, a message processing system that handled and/or otherwise has access to routing information for both messages performs the check, such as a network messaging and/or access service provider with which the sender is associated, performs the check. If the routing information for the current message does not match the corresponding information observed in the previous message, responsive action is taken. Using routing information to determine whether a source of an infected message should be notified is disclosed.
