在本实施例中，终端可以是接收到开始信号后开始获取红外摄像数据和可见光摄像数据，或者，也可以是在获得供电时始终获取红外摄像数据和可见光摄像数据，相对应地，可以在接收到结束信号后结束获取，也可以在失去供电后结束获取。其中，开始信号和结束信号可以由终端的使用者或视频拍摄场景中的特定事件的触发生成，也可以由后台服务器发送至终端。终端由开始信号和结束信号的控制获取红外摄像数据和可见光摄像数据，更适用于生物识别、活体检测等使用视频数据的时长较短的场景中，视频数据的时长短、数据量小，外发至其他设备时的耗时短，便于对其他设备对视频内容进行实时分析并完成下一步操作；终端由供电控制获取红外摄像数据和可见光摄像数据时，操作简单，更适用于长期的环境安全监控等场景中，视频持续录制，保障该场景的安全性。
步骤102，将红外摄像数据和可见光数据合成处理得到视频数据；其中，红外摄像数据包括红外光变化特征，红外光变化特征为红外补光装置获得第一光线变化规则，并根据第 一光线变化规则进行补光后，得到的视频特征；

在本实施例中，终端可以通过WIFI、4G、电力网络等通讯方式将视频数据发送至后台系统服务器，为后台系统服务器实时更新视频数据，便于后台系统服务器及时对数据进行分析，及时为终端的监控环境或交易环境的安全提供保障。
在本实施例的一个可选实施方式中，终端可以使用密钥将该视频数据加密后发送给后台系统服务器，该密钥可以是后台系统服务器的密钥的对称密钥，也可以是非对称密钥，将视频数据加密后发送，提高了视频数据的安全性。
在本实施例的一个可选实施方式中，终端还可以使用其存储的私钥或外接的电子签名 设备的私钥将视频数据签名后发送至后台服务器，后台服务器通过验签，即可进一步判断出该视频数据是否被截取并篡改，进一步保障了视频数据的安全性，提高了该视频数据的防伪效果。在本可选实施方式中，电子签名设备可以是终端的使用者的电子签名设备，也可以是终端的所属的营业网点的电子签名设备，使用用户的电子签名设备进行签名，可以进一步保障视频数据是用户本人录制的，且该录制行为经过了用户本人的同意，提升了视频数据的真实性，使用终端的所属的营业网点的电子签名设备，可以使得后台服务器进一步确认视频录制的地点，提高该视频数据的防伪效果。
步骤104，后台系统服务器接收视频数据，提取视频数据中的红外光变化特征，判断红外光变化特征是否符合第二光线变化规则，若符合，则视频数据为真；其中，第二光线变化规则与第一光线变化规则相匹配。
在本实施例的一个可选实施方式中，后台系统服务器提取红外光变化特征，可以包括：提取红外光的闪烁的频率、亮度或时长等内容。第二光线变化规则与第一光线变化规则相匹配，可以是，第二光线变化规则与第一光线变化规则相同，也可以是，第二光线变化规则可以由第一光线变化规则按照预设计算规则计算得到。第二光线变化规则与第一光线变化规则相同时，后台系统服务器判断视频数据是否为真的速度更快，第二光线变化规则由第一光线变化规则计算得到时，由于计算规则的保密性，视频数据的真伪判断更为安全可靠，避免后台系统服务器遭到攻击导致时产生的第二光线变化规则泄露的风险。
在本实施例的一个可选实施方式中，本方法还包括：步骤105，如果后台系统服务器判断视频数据为真，后台系统服务器判断视频数据中是否存在活体人脸。在本可选实施方式中，后台系统服务器在判断视频数据为真后判断该视频数据中是否存在活体人脸，可以进一步判断终端的使用者的真实性，有效防止视频、照片、面具等伪造人脸的攻击，进一步提高监控环境或交易环境的安全性。
在本实施例中，由于红外光并不是可见光，红外光变化特征无法通过人类的肉眼识别，只有通过特殊的设备才能够读出红外光线的变化，因此，通过红外光变化特征来判断视频数据的真伪，有着更高的安全性和可操作性。并且，当外界的光照环境比较暗时，通过红外补光装置的补光，能够增加视频数据的清晰度，进一步提高视频数据的可靠性。
通过本实施例提供的视频数据防伪方法，终端获得包括了符合第一光线变化规则的红外光变化特征的视频数据之后，发送至后台系统服务器，后台系统服务器从视频数据中提取红外光变化特征，并通过该红外光变化特征是否符合预设的第二光线变化规则，判断出该视频数据是否为真。通过红外光变化特征判断视频真伪的方式，避免了视频数据被非法截取并篡改时，后台系统服务器无法快速准确的识别的安全风险，提高了交易环境中的身份识别安全或终端监控环境的安全，且本技术方案并不增加现有的视频监控场景中的设备 数量，仅需对现有设备进行改造即可完成，易于推广应用。
