BACKGROUND

Description of Related Art

[0002] Computer systems (e.g., desktops, laptops, portables, etc) typically employ some form of a non-volatile data storage device such as a disk drive, or a solid state drive comprising a non-volatile semiconductor memory such as flash memory. A solid state drive typically emulates a disk drive so that the same communication protocol may be employed. That is, a host typically interfaces with a solid state drive using a standard disk drive communication protocol, such as the Advanced Technology Attachment (ATA) protocol.

[0003] Computer systems typically allow access to the Internet using a standard web browser (Internet Explorer, Safari, Firefox, etc.) and therefore have become significant platforms for consumer transactions and advertising. Web browsers store information in configuration files that help facilitate browsing sessions. For example, a website may store a cookie in a browser cookie file, wherein the cookie may include information for authentication and session tracking (state maintenance), or specific information about a user, such as site preferences or the contents of their shopping cart. Each time the user visits a particular website, or browses through different pages of a website, the corresponding cookie information may be transmitted to the website to facilitate the browsing session.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0019] FIG. 1A shows a data storage device 2 according to an embodiment of the present invention comprising a non-volatile memory 4 having a host operating system stored in an unprotected area of the non-volatile memory, a device operating system stored in a protected area of the non-volatile memory, and a device application operable to transmit a web browser file over the Internet, the device application stored in the protected area of the non-volatile memory (FIG. 1B). The data storage device 2 further comprises control circuitry 6 for executing the flow diagram of FIG. 1C. When a first read command is received from a host to load the host operating system (step 8), the device operating system is returned in response to the first read command (step 10). A second read command is then received from the host to load the device application (step 12), wherein the device application transmits the web browser file over the Internet (step 14).

[0020] In the embodiment of FIG. 1B, the protected area of the non-volatile memory is inaccessible by the host that boots the host operating system. In this manner, the device operating system and the device application are protected from being modified or disabled by the host. Any suitable technique may be employed to reserve the protected area in the non-volatile memory, such as by reserving a number of data locations and corresponding block addresses for internal use only.

[0021] Any suitable technique may be employed to return the device operating system instead of the host operating system during the initial boot operation of the data storage device. Suitable techniques are disclosed in U.S. Pat. No. 6,948,165 entitled "METHOD FOR INSTALLING AN APPLICATION PROGRAM TO BE EXECUTED DURING EACH BOOTLOAD OF A COMPUTER SYSTEM FOR PRESENTING A USER WITH CONTENT OPTIONS PRIOR TO CONVENTIONAL SYSTEM STARTUP PRESENTATION WITHOUT REQUIRING A USER'S PARTICIPATION TO INSTALL THE PROGRAM" the disclosure of which is incorporated herein by reference.

[0022] FIG. 2A is a flow diagram according to an embodiment of the present invention which extends on the flow diagram of FIG. 1C. When the device operating system executes the device application, the device application scans the file system of the host operating system (step 16) in order to locate the target web browser file to be transmitted over the Internet (step 14). After transmitting the web browser file, the device application generates a reboot command to reboot the host so that the host resends a request to load the host operating system (step 18) wherein the data storage device returns the host operating system (step 20). After the host operating system is loaded, the host operates normally including to execute the web browser application.

[0023] The device application may be executed in any suitable manner during the boot of the host. FIG. 2B is a flow diagram according to an embodiment of the present invention wherein while executing the device operating system (step 10) the device application is copied from the protected area of the non-volatile memory to the unprotected area (step 22). The host operating system is then modified (step 24) so that the device application is executed automatically when the host operating system is loaded and executed. For example, the device application (or alias) may be copied into a startup folder of the host operating system. The device operating system then generates a reboot command to reboot the host so that the host resends a request to load the host operating system (step 26). The data storage device returns the host operating system (step 28) which then executes the device application (step 30) which scans the file system (step 16) and transmits the target web browser file over the Internet (step 14).

[0024] In the embodiments of the present invention, any suitable web browser file may be transmitted over the Internet for any suitable web browser (Internet Explorer, Netscape, Safari, Firefox, etc.). FIG. 3A shows an embodiment of the present invention wherein the web browser file transmitted over the Internet comprises a cookies file (step 14). In one embodiment, the cookies file stores cookies generated by various Internet websites, wherein the cookies may include information for authentication and session tracking (state maintenance), or specific information about a user, such as site preferences or the contents of their shopping cart. Each time the user visits a particular website, or browses through different pages of a website, the corresponding cookie information may be transmitted to the website to facilitate the browsing session.

[0025] FIG. 3B shows an embodiment of the present invention wherein the browser file transmitted over the Internet comprises a history file (step 14). The history file stores information related to the history of the web browser, such as a history of websites visited by the user. FIG. 3C shows an embodiment of the present invention wherein the browser file transmitted over the Internet comprises a cache file (step 14). The cache file stores content related to websites visited by the user, such as the content of various web pages visited by the user.

[0026] FIG. 3D shows an embodiment of the present invention wherein the web browser file transmitted over the Internet comprises a bookmarks file (step 14). The bookmarks file stores a list of website addresses for quick access by the user during Internet browsing sessions. The bookmarks may be displayed in any suitable manner, such as in a drop-down menu or in a toolbar of the web browser.

[0027] FIG. 3E shows an embodiment of the present invention wherein the web browser file transmitted over the Internet comprises a security file (step 14). The security file may store configuration information for enabling/disabling certain security features of a web browser, such as enabling/disabling various program components (e.g., Java, .NET, ActiveX, etc.) that a website may attempt to download and run on the host computer together with the standard HTML scripts. Alternatively, the security file may store security certificates which enable secure communication between a website and the web browser over the Internet. In one embodiment, the security file comprises a list of websites having a particular security configuration.

[0028] FIG. 3F shows an embodiment of the present invention wherein the web browser file transmitted over the Internet comprises a preference file (step 14). The preference file may store configuration information, such as the address of a website displayed initially (the homepage) when the web browser is first launched.

[0029] FIG. 3G shows a dialog window displayed from a web browser for enabling/disabling cookies for selected websites. For example, if a user wants to block all cookies generated by a particular website, the user enters the address of the website and selects the "Block" button which adds the website address to the list of blocked websites. The list of website addresses and access setting is typically stored in a cookies exclusion file (a configuration file) for the web browser.
