嵌入软件的计量器具防弊系统研究

Based on Embedded Software Measuring Instruments Anti-Cheating System Research

针对目前我国有不法分子为了获取非法利益,将电子计量器具改变内部芯片代码进行作弊,提出了一种基于嵌入式软件的防作弊系统,以保证质检人员对作弊器具的有效检测。首次以嵌入式软件质量测评系统为基础,在审批计量器具之前提取其软件内部特征信息作为数字指纹并保存,在质检人员检测计量器具时,提取待检测器具的内部芯片程序信息并生成数字指纹,通过将生成的数字指纹与之前保存的数字指纹进行比较,就可以准确实现作弊计量器具的成功检测。实验结果表明,嵌入软件检测系统能够准确将作弊计量器具检测出来,具有一定的使用价值。

This paper proposed a new anti - cheat system based on embedded software, to ensure the quality inspection personnel to effectively detect instruments cheating. Based on embedded software quality evaluation system, This system extracts the internal features of the software and saves the information as a digital fingerprint prior to the approval of measuring instruments. When quality control personnel test the measuring instruments, the program information in the apparatus to be tested is extracted to generate the digital fingerprint of the internal chip. Through comparing the generated digital fingerprint with the previously stored, the instruments can be accurately measured to achieve the cheating detection. Experimental results show that the fraud detection system can accurately detect the measuring instruments.
