Research on face authentication technology based on companion robot

Under the background of the development of industrial Internet and digital economy era, artificial intelligence is widely used in all businesses of power grid, among which the identity authentication of personnel in substation operation and maintenance area is a common requirement in the business scenario of power grid. This paper proposes a " cloud to edge integration" solution based on offline feature extraction + cloud recognition and authentication, which extracts face features from the end side, compares face information in the cloud, and realizes identity authentication through minimized data transmission. Compared with the traditional non biometric identification means such as key and ID card, fingerprint and iris identification and other biometric identification means, this scheme has the advantages of insensitive identification operation, fast speed, high accuracy and good economic benefits, and has high promotion value.
