Identity recognition method based on block chain, information storage method and related device

The invention discloses an identity recognition method based on a block chain, an information storage method and a related device. The method is applied to the block chain network, and according to the invention, a hash sequence value is generated from a face front image; and the hash sequence value is stored in the block chain network, so that the obtained hash sequence value corresponding to thehuman face front image of the person is compared with the hash sequence value stored in the block chain network in subsequent identity recognition of the person by the user, and therefore, identity recognition can be performed on the person, and the efficiency of identity recognition can be improved. 本发明公开了一种基于区块链的身份识别方法、信息保存方法及相关装置，应用于区块链网络，本发明通过将人脸正面图像生成哈希序列值，并将该哈希序列值保存至区块链网络中，以使后续用户对人员的身份识别中，将获得的该人员的人脸正面图像对应的哈希序列值与区块链网络中保存的哈希序列值进行对比，从而对该人员进行身份识别，提升身份识别的效率。
