Abstract: Users access content using a variety of formats, where some formats provide stronger encryption or protections than others. Content transmitted over open protocols may expose content to unauthorized third parties or enable unauthorized use of the content. The content may be protected by converting the content to a set of instructions on a user device, where the instructions correlate characters to identifications and outlines of the characters with instructions for rendering the characters. Different segments of content may have different mappings between characters, identifications, and outlines to add time or resource use to attempts to reverse engineer the instructions.

Abstract: Electronic content such as an electronic book (e-book) that is referenced in or otherwise related to other content such as website content is identified, and a visual representation of the electronic content is generated. The visual representation is presented in conjunction with the website content, and a reader application for previewing the electronic content is launched via user interaction with the visual representation. Exiting the reader application causes a browser application that is rendering the website content to be automatically returned to a foreground state. A variety of actions are enabled via interaction with the reader application such as purchasing the electronic content, sharing the electronic content, or downloading a sample preview of the electronic content for later consumption.

Abstract: Techniques are provided for selectively and dynamically determining one or more words of an electronic book to present with comprehension guides. For instance, an electronic device rendering an electronic book may determine whether to display some, all, or no words of the book with comprehension guides for words within the electronic book based on word difficulty, contextual importance or aspects of the user. Techniques are also provided for determining the content of comprehension guides to be presented with the words.

Abstract: Media devices display content with fonts that contain sets of glyphs such as letters. Described herein are systems, devices, and methods for providing parameters for modifying a font. The modification of the font may increase readability for users of the media devices. The parameters may be determined based on at least one of an analysis of the content or an analysis of existing fonts and modifications already made to the existing fonts.
