    Abstract: A content server provides a browser of a client with encrypted content and with obfuscated browser-executable code for decrypting and displaying the content within the browser. Both the encrypted content and the obfuscated browser-executable code are generated based at least in part on an identity of the user requesting the content, and thus are different from encrypted content and obfuscated browser-executable code provided to other users. Further, in one embodiment the browser-executable code provided by the server changes periodically, such as weekly, thereby rendering ineffective any malicious software tools that obtain decrypted content by calling expected functions of the code. In one embodiment, the obfuscated browser-executable code for a user is pre-computed before that user makes a request for content.

    Abstract translation: 内容服务器为客户机的浏览器提供加密的内容和用于在浏览器内解密和显示内容的模糊浏览器可执行代码。 加密内容和模糊化浏览器可执行代码至少部分地基于请求内容的用户的身份而生成，并且因此不同于加密内容和提供给其他用户的模糊化浏览器可执行代码。 此外，在一个实施例中，由服务器提供的浏览器可执行代码周期性地改变，例如每周，从而通过调用代码的预期功能而使得通过调用预期功能获得解密内容的任何恶意软件工具变得无效。 在一个实施例中，在该用户对内容进行请求之前，预先计算用户的混淆浏览器可执行代码。

    Abstract: The functionality of an ereader module that is displaying an electronic book (“ebook”) is extended. A user identifier specifying a user using a client device executing the ereader module and an ebook identifier specifying the ebook displayed by the ereader module are received from the client device. One or more layers associated with the user are determined. One or more layers associated with the ebook are determined. A list of one or more layers is assembled. The layer list is transmitted to the client device. The client device enables the user to select a layer and use the selected layer to interact with content of the ebook.

    Abstract: Information about named entities referenced in an electronic book (ebook) is provided to a client device. An ebook identifier identifying the ebook is received from the client device. A set of layers available for use with the ebook is determined. The layers in the set provide information associated with the ebook and a layer in the set provides information associated with named entities referenced in content of the ebook. A content range identifying a range of content of the ebook for which layer information is requested and an identification of one or more of the layers in the set for which layer information is requested is received from the client device. Layer information associated with the ebook content identified by the content range for the identified layers is transmitted to the client device. The transmitted layer information includes information associated with named entities referenced by ebook content.
