Abstract: The subject disclosure is directed towards securing electronic commercial activity. Geo-locations are determined for one Internet transaction and another Internet transaction. These Internet transactions are related based on a common credential. Using timestamps, a relative travel speed between the geo-locations is computed for the Internet transaction and the other Internet transaction. Based upon the relative travel speed, a security component may invalidate the Internet transaction and/or the other Internet transaction.

Abstract: A system and related techniques manage the adding of digital images or other media to email messages using a comparatively straightforward insert-and-send scheme. A user may choose to insert or embed comparatively low-resolution versions of images or other media automatically published to a media server into an email message. The recipient of that media-enabled message may receive and view the email text message along with the low-resolution images in typical fashion using an email or other client. The recipient may choose to view one or more of the embedded images in greater resolution by linking or activating those images, for instance by moving a cursor and clicking into the selected image or other object. Activating the image or other media object from within the email pane may seamlessly transport the user to the media server's Web page to view a larger-resolution version of that image, for instance using a media player. Video, audio and other media may likewise be inserted into messages.
