Abstract: Systems and methods are described for enabling documents to be controlled by a sender, in a manner which is transparent to any end recipients. The invention include mechanisms enabling a sender to control documents sent to recipient, in a manner that (1) encrypts the message to ensure its security, and (2) restricts operations the recipient may perform on the received message. The recipient and sender need not agree on a control protocol in advance of the communication. Wide distribution of a Digital Rights Management System may be facilitated by use of self-installing modules, which integrate with existing software used for document publishing and retrieval. The modules are forwarded to unregistered recipients upon authentication of the recipient, and install automatically on the recipient's computer. The modules authenticate instructions from a sender, and, per instructions from the sender, may pre-empt certain types of operations on the e-mail by the recipient

Abstract: A method and apparatus implementing a separate child context for each applet (or similar element) of a browser. A described embodiment of the present invention provides one or more child contexts that correspond to elements in the HTML for a web page displayed by a browser. For example, each applet executed by the browser has a corresponding and separate child context. Each child context has an associated memory buffer. An orphan context is provided for behind the scenes drawing, where contents of the orphan context is indirectly drawn on a display screen via the buffer associated with the child context. The browser also has a parent context, which each child context points to. When a graphic is displayed via a widget, the widget draws the graphic (such as a panel or a non-pressed button) in the child context of the applet and sets a “damage” flag in the child context. When the browser performs its main browser loop, it checks the status of the damaged flag for each element (including each applet). If the browser finds a damage flag that is set, this means that something was written into the child buffer and that the parent buffer needs updating. In this case, the browser “pulls” the information from the child buffer into the parent buffer, which is then used to update the display screen.

Abstract: A system and method for receiving and rendering Unicode text in multiple languages on a set top box is disclosed. The system includes a set top box which receives an application program from a broadcast station. The set top box executes the application program. The application program includes Unicode character encoding text for display on a television coupled to the set top box. An operating environment running on the set top box includes a Unicode encoding engine which the application program invokes to display Unicode text. The encoding engine determines the language of characters in the text and invokes a rendering engine corresponding to the language of each character, thus enabling characters from different languages to be mixed in the same text string. The rendering engine has specific knowledge of the language, such as rendering direction and context. One or more glyph sets may be plugged in to the set top box to support different languages and fonts according the locale in which the set top box will be used. The rendering engine renders the characters using the glyphs in the glyph sets. Furthermore, glyphs not present in the set top box may be downloaded to the set top box along with the application program and rendered by a rendering engine. A set top box and method for efficiently storing and quickly retrieving the large number of Japanese Unicode characters using a hash table and hashing method in the set top box is also disclosed.

Abstract: A device may select a password and encrypt it utilizing a public key. The device may provide the encrypted password when an access request is received from a client. The client may obtain an unencrypted version of the password by submitting it to a private key server (which utilizes the private key to decrypt the password) and return the password to the device. When the device receives the unencrypted password from the client, the device may allow access. The device may generate the password once during operation. However, in some implementations, the device may generate a new password for each access request and may only respond to the most recently issued password. The device may generate, encrypt, and transmit a single password. However, in various implementations the device may generate, encrypt, and/or transmit a number of different passwords to support different access configurations.

Abstract translation: 设备可以选择密码并利用公钥加密密码。 当从客户端接收到访问请求时，设备可以提供加密密码。 客户端可以通过将密码提交给私钥服务器（使用私钥解密密码）并将密码返回到设备来获取密码的未加密版本。 当设备从客户端收到未加密的密码时，设备可能允许访问。 设备在运行过程中可能会生成一次密码。 然而，在一些实现中，设备可以为每个访问请求生成新密码，并且可以仅响应最近发布的密码。 该设备可以生成，加密和传输单个密码。 然而，在各种实现中，设备可以生成，加密和/或发送多个不同的密码以支持不同的访问配置。

If the browser finds a damage flag that is set, this means that something was written into the child buffer and that the parent buffer needs updating. In this case, the browser “pulls” the information from the child buffer into the parent buffer, which is then used to update the display screen. Other components, called reactive components, present special problems and are treated specially. Reactive components are drawn directly into both the child and parent contexts and buffers without waiting for the main browser loop.
