Data processing method, device and equipment

The invention discloses a data processing method, device and equipment. The method comprises the following steps: collecting original data of a current data collection burying point in at least one data collection burying point; determining noise corresponding to the original data according to the global sensitivity corresponding to the original data of the current data collection burying point and the privacy budget of the current data collection burying point; and scrambling the original data according to the noise to obtain scrambled data. By means of the mode, differential privacy protection of the data maintainer on the delivered data is achieved. 本发明公开了一种数据处理方法、装置及设备，该方法包括：获取至少一个数据采集埋点中当前数据采集埋点的原始数据；根据所述当前数据采集埋点的原始数据对应的全局敏感度和所述当前数据采集埋点的隐私预算，确定所述原始数据对应的噪声；根据所述噪声对所述原始数据进行加扰，得到加扰后的数据。通过上述方式，本发明实现了数据维护方对交付数据的差分隐私保护。
