Description

电子设备内置软件的防盗版装置及其方法Anti-theft device and method for electronic device built-in software 技术领域Technical field
本公开涉及电子技术领域，例如涉及一种电子设备内置软件的防盗版装置及其方法。The present disclosure relates to the field of electronic technology, for example, to an anti-piracy device and a method thereof for electronic software built-in software.
背景技术Background technique
随着互联网技术的快速发展和机顶盒终端设备的日趋智能化，机顶盒终端所承载的内容和功能随之增多。用户通过机顶盒终端不仅能收看精彩的节目内容，还可以实现浏览网页、搜索查询、游戏娱乐、社交互动以及网上购物等功能。With the rapid development of Internet technology and the increasing intelligence of set-top box terminals, the content and functions carried by the set-top box terminals have increased. Users can not only watch the wonderful program content through the set-top box terminal, but also realize the functions of browsing webpage, search query, game entertainment, social interaction and online shopping.
通常一种新电子产品推出后，在市面上都会出现抄袭，通常是对存储器内的可执行程序进行读取复制。对于机顶盒产品来说，可执行程序一般存放在闪存(FLASH)里。由于FLASH是可以直接脱离中央处理器(Central Processing Unit，CPU)的，其内部的程序可以通过其它设备直接读取出来。为了预防盗版软件，则须对FLASH进行相应的防盗措施。Usually, after a new electronic product is launched, plagiarism will occur on the market, usually by reading and copying executable programs in the memory. For set-top box products, executable programs are typically stored in flash memory (FLASH). Since FLASH can be directly separated from the Central Processing Unit (CPU), its internal programs can be directly read by other devices. In order to prevent pirated software, the corresponding anti-theft measures must be applied to FLASH.
通常采用的防盗措施是通过与第三方芯片厂商定制芯片识别号(CHIP ID)，该CHIP ID仅被机顶盒厂商知悉，从而实现保密。或者通过与第三方芯片厂家协调进行软件加密。但是这些防盗措施都对第三方芯片厂商有依赖性，在不能确定市场销售量大小的情况下找第三方芯片厂商定制芯片，可行性不高且成本不易控制。而且第三方芯片厂商的加密存在泄密的风险，可能被第三方破解。The commonly used anti-theft measure is to customize the chip identification number (CHIP ID) with a third-party chip manufacturer, which is only known by the set-top box manufacturer, thereby achieving confidentiality. Or by software encryption with third-party chip manufacturers. However, these anti-theft measures are dependent on third-party chip manufacturers. If you can't determine the size of the market, you can find a custom chip for a third-party chip manufacturer. The feasibility is not high and the cost is not easy to control. Moreover, the encryption of third-party chip vendors is at risk of being compromised and may be cracked by third parties.
因此，相关技术中的机顶盒还有待于改进和发展。Therefore, the set top box in the related art has yet to be improved and developed.

The anti-piracy device is disposed on a whole circuit board of the electronic device, and the device includes: a protective cover 10; and a first detecting module 40. The first detecting module 40 is configured to detect whether the protective cover 10 is detached and output a first detection signal; the core board 20 is disposed in the protective cover 10, and the core board 20 and the first detecting module 40 are electrically connected. Connected, the above software is stored in the core board 20, the core board 20 is arranged to recognize that the software is erased when the protective cover 10 is detached according to the first detection signal; and the battery 50 is set to give the first detection Module 40 and core board 20 are powered. The core board 20 recognizes that the built-in software program is erased when the protective cover 10 is detached according to the first detection signal, thereby avoiding theft of the program; and does not rely on the third-party chip manufacturer, and there is no risk of program leakage; thereby solving the core of the set-top box in the related art. The built-in software of the board is easy to be stolen by others.
参考图1B，本实施例提供又一种电子设备内置软件的防盗版装置，该软件防盗版装置设置在电子设备的整机电路板60上，该软件防盗版装置包括一保护罩10，设置在保护罩10内的核心板20，设置为检测电子设备外壳是否被拆卸并输出第二检测信号的第二检测模块30，设置在保护罩10内用于检测保护罩10是否被拆卸，并输出第一检测信号的第一检测模块40；用于对核心板20、第二检测模块30和第一检测模块40供电的电池50。核心板20根据第一检测信号 和第二检测信号识别出外壳和保护罩10均被拆卸时，对内置软件进行擦除。其中，第二检测模块30为该电子设备中可选的模块。Referring to FIG. 1B, the embodiment provides another anti-piracy device for the built-in software of the electronic device. The anti-piracy device is disposed on the whole circuit board 60 of the electronic device. The software anti-piracy device includes a protective cover 10 disposed on the The core board 20 in the protective cover 10 is disposed to detect whether the electronic device housing is detached and output a second detection signal, and is disposed in the protective cover 10 for detecting whether the protective cover 10 is detached and outputting the first A first detecting module 40 for detecting signals, and a battery 50 for supplying power to the core board 20, the second detecting module 30, and the first detecting module 40. The core board 20 is based on the first detection signal When the second detection signal recognizes that both the outer casing and the protective cover 10 are detached, the built-in software is erased. The second detecting module 30 is an optional module in the electronic device.
所述核心板20上可以设置有CPU、双倍速率同步动态随机存储器(Double Data Rate，DDR)和闪存FLASH，其中FLASH内存储有上述软件。在本实施例中，CPU设置为将第一检测信号和第二检测信号的电压值与预设的阈值进行比较来识别外壳和保护罩10的拆卸状态，并在至少有保护罩被拆卸时对FLASH内的程序进行擦除。The core board 20 may be provided with a CPU, a double rate synchronous dynamic random access memory (DDR) and a flash memory FLASH, wherein the software is stored in the FLASH. In this embodiment, the CPU is configured to compare the voltage values of the first detection signal and the second detection signal with a preset threshold to identify the disassembly state of the outer casing and the protective cover 10, and when at least the protective cover is removed The program in FLASH is erased.
在本实施例中，第二检测模块30和第一检测模块40采用光学检测方式来检测上述外壳和保护罩10是否被拆卸。通常整机电路板60装在电子设备内部，在外壳的遮挡下不会接受到自然光的照射。假如有人想盗版软件(主要指核心板20内的软件程序)，则会将外壳拆卸使整机电路板60暴露在光线下。相关技术中核心板20外没有设置保护罩10，可直接读取FLASH内的软件程序从而进行盗版仿制。当第二检测模块30检测到有光线则判定外壳被拆卸。由于有时拆卸外壳可能是检修整机电路板60上的其他部件，不一定是读取FLASH内的软件程序。本实施例通过增加一保护罩10来包围核心板20，在外壳被拆卸后核心板20仍不会被光照射到。如果要盗读软件程序，则要拆卸核心板20外的保护罩10使其暴露在光照下。为此，通过第一检测模块40可以判断保护罩10是否被拆卸，来识别核心板20的内置软件程序是否被盗读。In this embodiment, the second detecting module 30 and the first detecting module 40 use an optical detecting manner to detect whether the outer casing and the protective cover 10 are detached. Usually, the whole circuit board 60 is installed inside the electronic device, and the natural light is not received under the shielding of the outer casing. If someone wants to pirate software (mainly referred to as a software program in the core board 20), the outer casing will be removed to expose the entire circuit board 60 to light. In the related art, the protective cover 10 is not disposed outside the core board 20, and the software program in the FLASH can be directly read to perform pirate imitation. When the second detecting module 30 detects light, it is determined that the outer casing is detached. Since sometimes disassembling the casing may be to repair other components on the complete circuit board 60, it is not necessary to read the software program in the FLASH. In this embodiment, the core panel 20 is surrounded by the addition of a protective cover 10, and the core panel 20 is still not exposed to light after the outer casing is detached. If the software program is to be stolen, the protective cover 10 outside the core board 20 is removed to expose it to light. To this end, the first detecting module 40 can determine whether the protective cover 10 is detached to identify whether the built-in software program of the core board 20 is stolen.
在本实施例中，所述保护罩10可以为不透明金属保护罩，例如黑色金属保护罩，可以将CPU、第一检测模块40、FLASH和DDR全部罩在保护罩里面以隔离光线，即使外壳被拆卸也不会使FLASH暴露在光线下。参考图2，第一检测模块40和第二检测模块30分别对应包括第一光传感器401和第二光传感器301。第二光传感器301对整机电路板60上的第二光照强度进行采样并输出具有对应电平的第二检测信号。第一光传感器401对FLASH所在位置的第一光照强度进行采样并输出具有对应电平的第一检测信号。In this embodiment, the protective cover 10 may be an opaque metal protective cover, such as a ferrous metal protective cover, and the CPU, the first detecting module 40, the FLASH, and the DDR may all be covered in the protective cover to isolate the light even if the outer casing is Disassembly does not expose the FLASH to light. Referring to FIG. 2, the first detecting module 40 and the second detecting module 30 respectively include a first photo sensor 401 and a second photo sensor 301. The second photosensor 301 samples the second illumination intensity on the entire circuit board 60 and outputs a second detection signal having a corresponding level. The first photosensor 401 samples the first illumination intensity at the location of the FLASH and outputs a first detection signal having a corresponding level.
在室内正常光的照射下，光传感器内的光敏电阻会随着光照强度返回一个对应的阻值，通过电阻分压法，可将该随光变化的阻值转化为随光变化的电压，其中光照强度与电压成正比。将光照强度较低情况下(如黑暗状态下)采得的 电压值记为第一电压V1，将光照强度较高情况下(如正常白天拆机室内中午的自然光)采得的电压记录为第二电压V2。阈值可以设置为(V2+V1)/2，在出厂时进行设定。当两个检测信号的电压值小于阈值时，表明外壳和保护罩10未被拆卸；当两个检测信号的电压值大于等于阈值时，表明外壳和保护罩10被拆卸掉。Under normal indoor illumination, the photoresistor in the photosensor will return a corresponding resistance value with the light intensity. Through the resistor divider method, the resistance value of the light change can be converted into a voltage that varies with light. The light intensity is proportional to the voltage. When the light intensity is low (such as in the dark state) The voltage value is recorded as the first voltage V1, and the voltage obtained when the light intensity is high (such as the natural light at noon in the normal daytime disassembly room) is recorded as the second voltage V2. The threshold can be set to (V2+V1)/2, which is set at the factory. When the voltage values of the two detection signals are less than the threshold value, it indicates that the outer casing and the protective cover 10 are not disassembled; when the voltage values of the two detection signals are greater than or equal to the threshold value, it indicates that the outer casing and the protective cover 10 are removed.
下面以电子设备为机顶盒进行举例说明，CPU先判断第二检测信号的电压值是否小于阈值：是则正常工作；当第二检测信号的电压值大于等于阈值时，则表明机顶盒外壳被拆卸掉，发送通知信息给服务器。机顶盒内有相应的联网模块，CPU通过该联网模块可以读取机顶盒的媒体访问控制(Media Access Control，MAC)地址和身份(Identity，ID)号(每个机顶盒的MAC地址和ID号是唯一，在机顶盒被卖出时会记录哪些购买商买了哪些MAC地址和ID号的机顶盒)，通过网络上传到机顶盒公司的后台网络服务器，可跟踪是哪个购买商购买的机顶盒的外壳被拆卸。接着CPU判断第一检测信号的电压值是否小于阈值：是则不处理；在第一检测信号的电压值大于等于阈值时，则可以识别出保护罩10被拆卸，对FLASH内的内置软件程序进行擦除。The following is an example in which the electronic device is used as a set-top box. The CPU first determines whether the voltage value of the second detection signal is less than a threshold value: if it is normal operation; when the voltage value of the second detection signal is greater than or equal to the threshold value, it indicates that the set-top box casing is removed. Send notification information to the server. The set-top box has a corresponding networking module, through which the CPU can read the Media Access Control (MAC) address and identity (ID) number of the set-top box (the MAC address and ID number of each set-top box are unique). When the set-top box is sold, it will record which MAC addresses and ID number of set-top boxes are purchased by the purchaser, and upload to the set-top box company's back-end network server through the network to track which purchaser's purchased set-top box's casing is removed. Then, the CPU determines whether the voltage value of the first detection signal is less than the threshold value: if not, the processing is not processed; when the voltage value of the first detection signal is greater than or equal to the threshold value, it can be recognized that the protective cover 10 is removed, and the built-in software program in the FLASH is performed. Erase.
本实施例是对电子设备的FLASH内的软件程序进行擦除。在实施时，还可对其他需要进行保护的存储器的软件程序进行擦除，需将该存储器设置在保护罩10内，并对应设置检测外壳是否被拆卸的第二光传感器301和检测存储器是否暴露在光线下的第一光传感器401。电池50是为了防止盗版人员对CPU断电使其不能对FLASH进行擦除时，还能使第二光传感器301和第一光传感器401正常工作。可选地，电池50可以设置在保护罩10内。参考图3，电池50设置在保护罩10内，以防止盗版人员去除电池50使FLASH的内置软件不能被擦除。In this embodiment, the software program in the FLASH of the electronic device is erased. In implementation, the software program of the memory that needs to be protected may also be erased, and the memory needs to be disposed in the protective cover 10, and correspondingly, the second light sensor 301 that detects whether the outer casing is detached and the detection memory are exposed. First light sensor 401 under light. The battery 50 is configured to prevent the pirate personnel from operating the second photosensor 301 and the first photosensor 401 in order to prevent the pirate from powering off the CPU so that the FLASH cannot be erased. Alternatively, the battery 50 may be disposed within the protective cover 10. Referring to Figure 3, a battery 50 is disposed within the protective cover 10 to prevent pirates from removing the battery 50 so that the FLASH built-in software cannot be erased.
为了避免在外壳被拆卸后这两个光传感器被盗版人员发现，可对光传感器的外观进行调整，如伪装成电容或芯片的形状。这样就可以在盗版人员发现之前对FLASH内的程序进行擦除，以免盗版人员发现进行补救措施(如在较暗光下读取程序)。In order to avoid the two light sensors being discovered by pirates after the outer casing is removed, the appearance of the light sensor can be adjusted, such as disguised as a capacitor or a chip. In this way, the programs in the FLASH can be erased before the pirates find out, so that the pirates can find remedial measures (such as reading the program in a darker light).
在实施时，第二检测模块30和第一检测模块40还可以采用其他方式检测电子设备外壳和保护罩10是否被拆卸。如在外壳和保护罩10上设置一引线连 接整机电路板的地和CPU，则该引线一直输出低电平给CPU，CPU根据低电平判定外壳和保护罩10未被拆卸。引线的长度尽可能短且易断，以便外壳和保护罩10被打开时就能断掉，被拆卸时则会断掉。引线断开则无电压输出给CPU，CPU判断引线悬空则识别被拆卸。本实施例对拆卸检测方法不作限定。In implementation, the second detecting module 30 and the first detecting module 40 may also detect whether the electronic device housing and the protective cover 10 are removed by other means. If a lead wire is placed on the outer casing and the protective cover 10 When the ground of the circuit board and the CPU are connected, the lead always outputs a low level to the CPU, and the CPU determines that the outer casing and the protective cover 10 are not disassembled according to the low level. The length of the lead wire is as short and fragile as possible so that the outer casing and the protective cover 10 can be broken when opened, and broken when removed. When the lead is disconnected, no voltage is output to the CPU, and the CPU judges that the lead is floating and the identification is removed. This embodiment does not limit the disassembly detection method.
