Abstract

The present invention provides a data encryption method and device, wherein the method includes: the terminal obtains the first encrypted identity information in the user ID card through NFC; sends an identity verification request to the server, and receives the response request and the communication key returned by the server , to perform mutual identity verification with the server to verify whether the identity is legal; when the server is determined to be legal, use the communication key to encrypt the first encrypted identity information; send the encrypted first encrypted identity information to the server; receive the The second encrypted identity information; using the communication key to decrypt the second encrypted identity information to obtain the second identity information; displaying the second identity information. Through the technical solution, the data of the ID card is encrypted to ensure the security of the data transmission of the ID card.

Description

technical field [0001] The invention relates to the technical field of identity authentication, in particular to a data encryption method and device. Background technique [0002] At present, ID card recognition is widely used in many fields such as public security, transportation, financial securities, logistics transportation, hotel reservations, etc. However, the existing ID card identification devices are stand-alone devices, resulting in huge waste of resources, high system cost, long deployment cycle, inconvenient use and portability, and high upgrade and maintenance costs. Contents of the invention [0003] The invention provides a data encryption method and device for realizing the security of protecting identity data. [0004] According to the first aspect of the embodiments of the present invention, there is provided a data encryption method for a terminal device, including: [0005] Obtain the first encrypted identity information in the user ID card through NF...
