Description

Read-only method and system for operating portable devices

technical field

The present invention relates to a read-only method and system, in particular to a read-only method and system for operating portable devices.

Background technique

Some portable devices require setup or initialization before they can start operating. For example, fingerprint recognition flash memory will require users to register their fingerprint information into the device, and then the security measures will take effect. Because the fingerprint recognition flash memory has no user interface to interact with the user, it must be assisted by a host computer such as a computer. Usually software needs to be installed or executed on the host computer so that related initialization tasks can be performed.

Manufacturers of fingerprint-reading flash memory face a problem if a computer is used to run software. For each operating system that supports the computer, the manufacturer has to provide a corresponding version of the software, which is an additional cost.

There is a common method used to solve the above mentioned problem. Instead of using software that must be installed and executed on the host, an HTML file is sent to the web browser on the host to be able to interact with the user and guide them to an online web page for further installation or partial completion of the same Initialize the job. However, for some portable devices, executing the HTML file(s) in the web browser to interact with the attached device may be blocked by the security system in the operating system. For example, if an HTML file provided by the fingerprint flash memory requires writing data into the fingerprint flash memory while the fingerprint flash memory is connected to the computer, because the default browser security overrides any desired When trying to write data to the local file system, the security system of the host may pop up a warning message to warn the user that the next action will have potential security risks. Obviously, the fingerprint flash memory is regarded as a local storage device relative to the computer. Many people don't understand how the security system works, and think that there is a security risk in the fingerprint flash memory. This can lead to a lot of phone calls about the above issues, and even the return of fingerprint flash memory.

There is thus a need for how to configure or initialize a portable device linked to a host without being hindered by a security system. One teaching is given in US Patent No. 7,676,675. US Pat. No. 7,676,675 has steps to accomplish this by considering the portable device as a remote client who wants to access the local desktop computer. However, this patent requires additional listening sockets to be arranged at both ends, which cannot be accepted by users who purchase the portable device.

The present invention proposes an accurate but simple read-only method and a system for operating portable devices using the method. The system spans both the device and the host, so that existing components available on the host can be used effectively without installing new components. Therefore, the requirements mentioned above can be met.

Contents of the invention

As can be seen from the above description, for today's portable devices, when they are connected to the host computer for setting or initialization, if the manufacturer does not provide specific driver software for a specific operating system, it can be accessed through the webpage. Completing setup or initialization will be blocked by the operating system. However, existing technologies have been unable to break through such barriers. The present invention proposes a solution to such a demand.

According to an aspect of the present invention, a read-only system for operating a portable device includes: a portable device, including: a memory unit with a file system directory, and a program implanted HTML files or an application program file for storing data in a physical and/or virtual memory space, the aforementioned program is programmed by a scripting language or a programming language, the application program file is embedded in or points to an operation; and a processing unit , for transmitting HTML files or application files from the memory unit, running a monitoring program, executing a service required by the monitoring program, and transmitting data in the address; and a host computer, connected with the portable device, for Receiving the HTML file or application program file, including: a display unit for displaying web pages on a browser, or displaying the execution result of the application program file, the aforementioned browser displays the content of the HTML file and executes the embedded program; and a processor for running an operating system and the browser or application program files.

The host regards the portable device as a storage device indicated by the file system directory structure. The browser installed on the host executes the HTML file and executes the embedded program. The embedded program or application file operates to translate a selected selection attribute or a message entered by the user corresponding to a service into a corresponding URL or combination of URLs, the aforementioned single URL A combination of URLs or global resource locators, respectively, point to one or more files located in a file system directory. the operating system accesses the one or more files by searching for addresses of the one or more files in an index table of the file system directory and then requesting the portable device to read data at the address(es); The watchdog checks the addresses sent by the operating system and determines whether the address(s) correspond to the service. If the monitoring program finds that the address(s) correspond to the service, the monitoring program notifies the processing unit to execute the service. The address(es) provided by the file system directory is an index number of a memory space in the portable device.

Preferably, the file system directory is FAT (File Allocation Table, file allocation table), FAT16, FAT32, exFAT (Extended File Allocation Table), NTFS (New Technology File System, new technology file system), ext2, ext3, ext4, HFS (HTTP File Server, network file server), HFSX, or ISO9660 (international standard format). The index table of the file system directory is a file allocation table in the FAT file system, an index node (inode) in the extended file system, or a master control file table in the new technology file system (NTFS). The watchdog has a default table or rules linking addresses to corresponding services. The program or application operates to interact with the user to obtain the selected attributes or input information. The selection attribute appears to the browser in the form of a radio button, check box, or drop-down menu. Alternatively, the selection attribute appears in the browser as an image that, if clicked, triggers a specific service. The information is input by a text input box on the browser, and the scripting language is a programming language used by JavaScript or HTML5. The portable device receives and executes commands/information from the user through the service, and the service includes initializing the portable device, configuring the portable device, performing an action of the portable device, providing the portable device A piece of information within, or cut off the connection with the host.

According to the present invention, the portable device is connected to the host through a wireless or wired connection. The wireless connection method uses a Wi-Fi module or a Bluetooth module. This wired connection uses a USB connector, SD card slot, e-SATA connector, Lighting connector or Thunderbolt connector. The portable device is a hard disk, a flash memory, a solid state drive, a fingerprint reader, or a fingerprint flash memory, and the host is a desktop computer, a notebook computer, a tablet computer or a smart phone. The display unit is a monitor, a screen, or a touch screen. The host further includes an input device for selecting the service option. The input device is a mouse, a keyboard or a touch screen.

According to another aspect of the present invention, a read-only method for operating a portable device includes the steps of: connecting a host computer and a portable device; providing a file system directory and plant from the portable device; Enter an HTML file of a program into the operating system of the host; initialize a browser to run the program in the HTML file by the operating system; input a message to the interface of the browser or select an option attribute from the interface; translate The selected attribute and/or information is a global resource locator or a combination of global resource locators; the operating system translates the global resource locator or the combination of global resource locators into a read action; by searching in the file The address of the one or more files in an index table of the system directory and then request the portable device to read the data on the address(s), access one or some files located in the file system directory, the aforementioned (some) files are pointed to by the global resource locator or the combination of the global resource locators; during the (some) file access process of the portable device, monitor the (some) access addresses; find the corresponding to the a service of the access address(es) of the portable device; and execution of the service by the portable device.

As can be seen from the above description, in the system provided by the present invention, when the browser requests access to the portable device connected to the host, the memory unit is accessed and tracked, and the corresponding service can be provided by the portable device implement. With such a technique, the setting or initializing operation can be completed through the webpage, which will not be blocked by the host computer security system.

Detailed ways

The present invention will be described more specifically by referring to the following embodiments.

Please refer to FIG. 1, which illustrates a read-only system 10 according to the present invention. The read-only system 10 is used to operate a portable device. A fingerprint flash memory 100 is used as an example of the portable device. For the fingerprint flash memory 100, the user needs to use a host computer, the notebook computer 200, to register his fingerprint into the fingerprint flash memory 100, so that the fingerprint flash memory 100 can start to work. The ROM system 10 is a good example for initializing the fingerprint flash memory 100 without being blocked by the notebook computer 200 security system.

As mentioned above, the read-only system provided by the present invention spans the device end and the host end, and at least a part of the notebook computer 200 should have corresponding functions, which will be described later. For an ordinary laptop, these functions are handled by specific components, such as processors or modular chips. The present invention implements the read-only system 10 using only available electronic components, and the critical part is in the fingerprint flash memory 100 .

The fingerprint flash memory 100 includes three main units: a memory unit 110 , a processing unit 120 , and a USB connector 130 . It can also have other components to perform the functions of the fingerprint reader and the flash memory, but these are not the main points to be discussed in this embodiment. The fingerprint flash memory 100 can be accessed by the operating system of the notebook computer 200 .

The storage unit 110 has an HTML file 111 and a file system directory 112 . The HTML file 111 provides information to the user via a display unit, and interacts with the user by selecting an option it provides or inputting a piece of text information. The HTML file 111 is embedded with a program programmed by a scripting language or programming language. The program can translate user selections or information into a corresponding URL or combination of URLs (this will be described in detail later). Javascript is an applicable scripting language. As for the programming language, C++ and Java are often used. In fact, no matter it is a script language or a program language, as long as it can meet the functional requirements of the present invention, it will be stored in the memory unit 110 .

The main function of the memory unit 110 is to store data. Please continue to refer to FIG. 1 , some data can be stored in the memory space 114 for reading. It should be noted that there is a reserved memory space 113 in the memory unit 110 . The reserved memory space 113 only stores some default data for operating the read-only function, and no other data is stored here. The reserved memory space 113 can be physical and/or virtual memory space. If the reserved memory space 113 is a virtual memory space, each minimum read/write unit can only include the header of a file, and the entire virtual memory space can be constructed by an emulation program, so that the operating system of the notebook computer 200 believes that there is such a The data of is in the reserved memory space 113. Certainly, the reserved memory space 113 may be part of the physical memory space and part of the virtual memory space, which vary according to the design. It is emphasized that the smallest read/write unit is a "page" in the NAND flash chip used by the memory unit 110 . If the present invention is applied to other portable devices, such as flash memory or solid state hard disk, one page is also the minimum read/write unit. However, if the portable device to which the present invention is applied uses a hard disk as the memory unit 110, the minimum read/write unit should be a block.

The file system directory 112 indicates a file system, which has hierarchical subdirectories and logical files stored therein, and a corresponding physical address somewhere in the memory unit 110 . The file system provides pages in reserved memory space 113 and free memory space 114 referenced by single digits. The file system directory 112 is implemented by a conventional file allocation table (FAT) or FAT with a flash translation layer (FTL). In fact, the file system directory 112 can also be FAT16, FAT32, exFAT, NTFS, ext2, ext3, ext4, HFS, HFSX, or ISO9660. For the operation of the read-only system 10, the file system directory 112 must have data stored in many layers, because the spirit of the present invention is to observe the access of some specific pages and decide to activate a corresponding service. If the default data, such as a text file, is fetched from the operating system's cache, so that the read of those pages will not be performed, regardless of whether the file is read or not, the read-only system 10 cannot operate correctly. In this embodiment, the virtual memory space in the reserved memory space 113 is used. In this way, the file system has also become a simulated file system, and the file system directory 112 makes the operating system believe that the file system exists but actually does not exist. Similarly, if using physical memory space, the file system is a normal file system with actual FAT and stored data. As mentioned above, the reserved memory space 113 can be a part of the physical memory space and a part of the virtual memory space, that is, a mixed physical and simulated file system is used. The architecture of the virtual memory space will be described later.

The processing unit 120 is used to transmit the HTML files from the memory unit 110 to the notebook computer 200 , and it can also run a monitoring program 121 and perform a service, which is required by the monitoring program 121 . At the same time, the processing unit 120 can transmit the data of the page (address) in the memory unit 110 according to the requirement of the notebook computer 200 . The USB connector 130 is a wired connection for transferring HTML files. In fact, it could be another connector, such as an eSATA connector. It can also be a wireless connection for transmission. The wireless connection can be realized by a Wi-Fi module or a Bluetooth module.

The host computer, laptop 200, is connected to the fingerprint flash memory 100 and receives the HTML file (or application file, if used). As mentioned above, although there are many electronic components in the notebook computer 200, only three of them are required, and each has a specific function. They are a USB port 210 , a display unit 220 , and a processor 230 . Obviously, the USB port 210 is used to connect the USB connector 130 and transmit data from the USB connector 130 to the processor 230 . If the USB connector 130 is changed to an eSATA connector, the USB port 210 will also be replaced by another eSATA port. If the USB connector 130 is replaced by a corresponding module, such as a Wi-Fi module or a Bluetooth module, the USB port 210 will be replaced by the corresponding wireless module.

The display unit 220 can display the webpage on a browser, and the browser displays the content of the HTML file. The browser also executes the embedded program (or displays the execution result of the application file, if any). The purpose of the display unit 220 is to facilitate user interaction with the read-only system 10 . The processor 230 is used to run the operating system and browser (or application program files), and it can also be a general central processing unit in the notebook computer 200 . For the convenience of reading the manual, the operating system and the browser are marked as 231 and 232 respectively. When a global resource locator requested by the browser 232 is a web page (http), the operating system 231 can perform web services. Global resource locators can also be used for file transfer (ftp), email (mailto) and many other applications. The operating system 231 can also provide file services according to the directory information of the file system, and translate the directory path of a file into a page number to access the reserved memory space 113 and the free memory space 114, thereby achieving page access.

The notebook computer 200 regards the fingerprint flash memory 100 as a storage device, and the storage device is pointed to by the file system directory 112 . Because a virtual memory space is used, the content of the reserved memory space 113 does not have to physically exist. For a better understanding, please refer to Figure 2. FIG. 2 shows the detailed structure of the memory unit 110 . The file system directory 112 maintains the correspondence between logical files (directory paths) and virtual memory spaces (pages). For example, page P001 records the corresponding relationship of data, the data does not exist but has header and some information stored in pages P101 and P102. If the GPS requests to access the non-existent data, the data in the page P001 will return the page numbers of P101 and P102 to the operating system 231, so that the operating system 231 will try to obtain the data in the pages P101 and P102. Similarly, page P004 will return the page number of page P110 and page P006 will return the page number of page P124 if requested by the corresponding global resource locator.

When the notebook computer 200 is connected to the fingerprint flash memory 100 by connecting the USB port 210 and the USB connector 130 , the fingerprint flash memory 100 is powered by the notebook computer 200 . After a few seconds, the processing unit 120 will send the HTML file (or application program file) and file system directory information (shown by the dotted arrow in FIG. 1 ) to the operating system 231 . When the operating system 231 receives the HTML file, the browser 232 installed in the notebook computer 200 will automatically execute the HTML file and the embedded program.

The content of the HTML file provides a user-browser interface with a plurality of selection attributes, and each selection attribute corresponds to a service. Once the service is selected, the fingerprint flash memory 100 will execute it. The service fingerprint flash memory 100 receives and executes commands/information from the user. The service includes initializing the fingerprint flash memory 100, configuring the fingerprint flash memory 100, executing an action of the fingerprint flash memory 100, providing A piece of information in the fingerprint flash memory 100 , or cut off the connection between the notebook computer 200 and the fingerprint flash memory 100 . Other services can be cited, and the present invention is not limited. For illustration purposes, all services will be used in the following operation example.

Once a selection attribute is selected or a user enters a message, the embedded program (or application file) runs to translate the selection attribute to a specific URL or combination of URLs. The global resource locator(s) can each be pointed to one or more files located within the file system directory 112 . The operating system 231 accesses the file(s) by searching the file address(es) in the index table of the file system directory 112 and then requesting the fingerprint flash memory 100 to read the data at the address(s). The address of the file system directory 112 is the index number of a memory space in the fingerprint flash memory 100 , such as a page. Here, the index table of the file system directory 112 is a file allocation table in the FAT file system. In practice, it can also be an index node (inode) in an extended file system, or a master file table in NTFS. Please still refer to Figure 1. When the operating system 231 searches with a global resource locator (shown by the solid arrow in FIG. 1 ) of the file system directory 112 index table, it finds the page P001 at this address. Next, the file system directory 112 returns the data indicated by the global resource locator to be stored in the pages P101 and P102 (shown by the dotted arrows in FIG. 1 ). Finally, the operating system 231 accesses pages P101 and P102 in the reserved memory space 113 in the form of requesting the fingerprint flash memory 100 to read data (shown by dotted line arrows in FIG. 1 ). A total of 3 pages are accessed. It is also possible to access two pages at a time if the particular data indicated by the GPS is stored in one page. In this example, the two pages of data may have a larger storage capacity, or may be logically stored in an emulated file system with many levels of subdirectories.

The monitor program 121 monitors the execution process of the page access. If a page access is to a physical memory space of the file system directory 112, normal file access is performed. Conversely, if a page access is to the virtual memory space of the file system directory 112, the accessed page is translated into the corresponding service. The monitoring program checks the addresses issued by the operating system 231 and determines whether the address(s) correspond to the service. If the monitoring program finds that the address(s) correspond to the service, the monitoring program notifies the processing unit 120 to execute the service. The address(s) provided by the file system directory 112 is an index number of a memory space in the fingerprint flash memory 100 .

The monitoring program 121 may have a default table of pages (or rules) about addresses and corresponding services. The monitoring program 121 checks the addresses issued by the operating system 231 and determines whether the address(s) correspond to the service. If the monitoring program finds that the address(s) correspond to the service, the monitoring program notifies the processing unit 120 to execute the service.

The selection attribute can be selected or the user enters a message via the browser 232 , the information is entered into the browser 232 from a text input box. This information has the same functionality as selecting attributes. In fact, the selection of selected attributes appears in the browser 232 in the form of radio buttons, check boxes, or drop-down menus. They can also be presented in the form of an image that, if clicked, triggers a specific action. Service, select attribute form is not limited by the present invention. The purpose of the program (or application program) is to interact with the user to obtain the selection result or input information.

The following is an example of operation, see Figure 4. The display unit 220 presents the browser 232 with the selected attributes described above (initializing the fingerprint flash memory, configuring the fingerprint flash memory, performing fetching a fingerprint, providing a fetched fingerprint image, and disconnecting the fingerprint flash memory Connection). The corresponding service is displayed in a drop-down menu. When a selected attribute is selected in the browser 232, the operating system 231 of the notebook computer 200 will access a global resource locator according to the default list of global resource locators. Please refer to Figure 5, which shows the structure of some files in the virtual memory space. The fingerprint flash memory 100 is regarded as a local disk by the notebook computer 200 . There are 5 root directories: A1, B1, C1, D1 and E1. Each root directory has many subdirectories. For example, the root directory A1 is a subdirectory A2 and the subdirectory A3 of the subdirectory A2. There are 100 files in subdirectory A3, other root directories have similar structure. All files in the virtual memory space are regarded as described in FIG. 6 .

A selection attribute corresponds to some specific global resource locator. Since a file pointed to by a GPS may be cached by the operating system 231 of the notebook computer 200, once the GPS is initiated by the operating system 231 to access the file, in accordance with the spirit of the present invention, the used GPS The URL will be discarded, and another specific URL will be used for the next access to the same selection attribute. For example, when the user selects "initialize fingerprint flash memory" to conform to the default list of the global resource locator, the browser 232 initializes the fingerprint flash memory 100 for the first time, and the operating system of the notebook computer 200 will access file://s:/A1/A2/A3/1.txt. Then, the monitoring program 121 will know that the file pointed to by the global resource locator is accessed. The monitoring program 121 will notify the processing unit 120 to initialize the fingerprint flash memory 100 for use. If the fingerprint flash memory 100 is asked to redo "Initialize fingerprint flash memory" once, the same execution will run. However, on the second time, the global resource locator changes to: file://s:/A1/A2/A3/2.txt. The page corresponding to the access will not be used twice. Theoretically, the same selection attribute can be selected 100 times until all globs are exhausted. If the manufacturer of the fingerprint flash memory 100 expects it to be reset many times, the number of global resource locators will be even greater. According to the present invention, if the fingerprint flash memory 100 is plugged into other computers, the (some) used global resource locators can be used again, because the information of the file system directory is identifiable to other computers. New (even for a laptop 200, unplugged and reinserted would count as new), the cached file function will not link to the page where the original file was stored.

It should be emphasized that it is not important whether the file pointed out by the global resource locator actually exists, and the operating system 231 does not need to read it. The browser 232 may be set to ignore the feedback information from the reserved memory space 113 . The number of directory layers is not necessarily three as shown in FIG. 6 , but may be greater than three. The file system directory 112 may be another arrangement in which a file is located in a certain level and the next accessed file is in a lower level. For example, the global resource locator used to get the fingerprint for the first selection execution is: file://s:/C1/C2/C3/1.txt, and the same selection attribute for the second selection is: file://s: /C1/C2/C3/C4/2.txt, the third time will be: file://s:/C1/C2/C3/C4/C5/3.txt. Among them, A4 is a subdirectory of C3, and C5 is a subdirectory of C4.

Of course, the global resource locator does not have to point to a text file, it can also point to other kinds of files, such as HTML files. At the same time, the monitoring program 121 can keep track of multiple GPS locators for a selected attribute, and then the corresponding service can be executed. Another embodiment is shown in FIG. 7 . In this embodiment, a selection attribute points to two global resource locators. That is, once the selection attribute is selected, the operating system of the notebook computer 200 will access pages of two different global resource locators. For example, if the user selects "Disconnect Fingerprint Flash", the global resource locator file://s:/E1/E2/E3/1.HTML and file://s:/I1/I2/I3/ 1. The page pointed to by the HTML will be accessed. Then the monitoring program traces the access situation, and the corresponding service will be executed. Likewise, when many URLs (not shown) correspond to a selection attribute, the used URLs will be discarded, as described in the previous embodiments.

In the previous embodiments, a virtual memory space and an emulated file system were used. Meanwhile, the portable device is a fingerprint flash memory and contains non-volatile memory. However, according to the present invention, portable devices with a hard disk as a memory unit can also be used.

Please refer to FIG. 3 , the fingerprint flash memory 100 is replaced by a fingerprint hard disk. Therefore, the reading and writing of the memory unit 110 is in a "block". Because the physical memory space is used, the content of the reserved memory space 113 should physically exist. For example, the block B001 of the file system directory 112 records the corresponding relationship of the data in the blocks B101 to B104. If a global resource locator requires access to the data, the data in the block B001 will feed back the block numbers B101 to B104 to the operating system 231, so that the operating system 231 will try to obtain the data in the blocks B101 to B104 in the future, and the data Must be all and existing in blocks B101 to B104. Similarly, block B004 feeds back blocks B127 to block B143, and block B024 feeds back blocks B179 and B180 if required by the corresponding global resource locator.

It should be noted that the scripting language is not limited to Java script, it may be a programming language used by HTML5 (Hyper TextMarkup Language 5) in the future. The USB connector 130 is not limited to a USB or eSATA connector, and an SD card slot, a Lighting connector or a Thunderbolt connector can be used according to different operating systems. The portable device is not limited to the fingerprint flash memory 100, it can be a flash memory, a hard disk, a fingerprint reader, or other devices that need to operate the read-only system. Of course, the corresponding services will also change accordingly. For example, for flash memory, the service may be to lock access, provide ECC function, and so on.

In another embodiment, the host computer can be a desktop computer, tablet computer or smart phone. In the case of tablet computers and smart phones, the connection between the host and the portable device is not a wired connection. Such products can use wireless connections. Preferably, the wireless connection method complies with Wi-Fi or Bluetooth specifications. The display unit could be a touchscreen, a regular screen, or even a remotely connected monitor. The host side can include input devices for selecting selected attributes, such as a mouse or a keyboard can be used for the notebook computer 200 . Touch screens are an option for portable devices such as tablet computers.

According to the above, the general read-only method used to achieve the same function of the read-only system 10 is summarized as follows, please refer to FIG. 8 . Firstly, connect a host (such as the fingerprint flash memory 100 ) and a portable device (such as the notebook computer 200 ) ( S01 ). Then, provide a file system directory and an HTML file embedded in a program from the portable device to the operating system of the host (S02). The operating system initializes a browser to run the program in the HTML file by the operating system (S03). Thus, the browser will provide an interface to the user. A selection attribute (or information) is input by the interface of the browser (S04). As mentioned above, selection attributes can be selected from a bunch of options, or typed in manually. The program translates the selection attribute (and/or information) into a URL or a combination of URLs (S05). The browser translates the global resource locator(s) into a read action (S06). Then, the operating system accesses the file system directory by searching the address of the one or more files in an index table of the file system directory and then requesting the portable device to read the data at the address(es). One or some of the files, the aforementioned file(s) are pointed by a global resource locator or a global resource locator (S07). A monitoring program can be used to monitor the accessed address(s) during the file(s) access process of the portable device (S08). By finding a service corresponding to the access address(s) on the portable device (S09), the portable device executes the service (S10).

Although the present invention has been disclosed above in terms of implementation, it is not intended to limit the present invention. Any person skilled in the art may make some changes and modifications without departing from the spirit and scope of the present invention, and all of them fall within the scope of the present invention. within the scope of protection of the invention.
