The invention provides a tamper-proofing method for an electronic stop board information issuing system, which belongs to the technical field of electronic stop boards, and comprises the following steps: extracting a timestamp of each electronic stop board point in a system layout, and obtaining an information change set of each time point on the timestamp, determining an inconsistent coefficient of the first information and the second information in n1 adjacent time points and a time influence coefficient of issuing operation corresponding to the second information at each time point on the corresponding received first information, judging a tampered probability time abnormal line of the first information at each time point, and performing abnormal section division, determining an issuing protection mode according to the segment tampering set of each abnormal segment, and setting an anti-tampering triggering condition; and when the new time point arrives, performing security protection on the first information of the new time point in combination with the mode change coefficient corresponding to the second information of the new time point. The accuracy of information issuing and information presentation is ensured, and the timeliness of information acquisition by passengers is improved.
本发明提供了一种电子站牌信息发布系统防篡改的方法,属于电子站牌技术领域,包括:提取系统布局中每个电子站牌点的时间戳,并获取时间戳上的每个时间点的信息变更集合,确定n1个相邻时间点内的第一信息与第二信息的不一致系数以及每个时间点的第二信息所对应下发操作对相应所接收第一信息的时间影响系数,判断每个时间点下第一信息的被篡改概率时间异常线并进行异常段划分,并按照每个异常段的段篡改集确定下发保护方式,并设置防篡改触发条件;当到达新的时间点时结合新的时间点的第二信息所对应的方式变化系数,对新的时间点的第一信息进行安全保护。保证信息下发以及信息呈现的精准性,提高乘客对信息获取的及时性。
