提出了一种针对百度地图坐标加密算法的解密方法，利用百度开放的坐标转换接口获取多组GPS和百度地图坐标对，基于BP神经网络拟合出逆转换函数，利用训练后的BP网络来预测新的百度坐标所对应的GPS坐标。实验结果证明，该方法得到的GPS坐标与实际的GPS坐标较为接近，因而可以达到较为理想的解密结果。

This paper presents a decryption method of Baidu map’s coordinates. A converting interface from GPS coordi-nates to Baidu map’s coordinates given by Baidu is utilized to get pairs of GPS-Baidu coordinates. The inverse convert-ing function is fitted based on BP neural network. The trained BP network is used to predict GPS coordinates correspond-ing to some new Baidu coordinates. Experimental result demonstrates that the converted GPS coordinate given by this method is closed to the real GPS coordinate. Hence the decrypted result is ideal.
