Abstract: Images that appear in content are often of low quality, so there may be reason to provide higher quality images to a user. When content, such as a web page, is detected as having an image, a system may generate a query that can be used to retrieve the image from a search engine. The query also causes the search engine to identify other images, which, since they satisfy the query, may be similar to the original image. An interface may be presented to the user that presents these alternative images. In this way, the user can be shown images that are similar to that which the original content author wanted the user to see, but where the additional images may be of higher quality.

Abstract: Techniques for correlation of users to IP address lease events are described herein. In one or more embodiments, an audit system is provided to collect IP address lease events from a DHCP server and authentication data from one or more sources of authentication data. The audit system may store the collected data in a common data store. The common data store may be searched to correlate the IP address lease events with authentication data. In this manner, a comprehensive record of the computers or devices used by a user within a given time period can be established through correlation of the historical IP address lease information from the DHCP server with the user login information from an authentication source. This may occur by matching events using timestamps of the events and the IP address and/or other common elements between two event sources.
