Background
Information interaction refers to the transmission and communication activities of information, data and technical knowledge in all aspects of nature and society. Because all information is visually transmitted in the information interaction process, the information interaction has certain security risks, such as the risk that the communication content is known, the risk that the communication content is stolen, the risk that the communication content participates in communication by impersonating identity, and the risk that the communication content is modified. Taking a payment code payment means which is common in the field of mobile payment as an example, in a normal mobile phone payment process, a customer presents a WeChat or Paibao payment code, and a merchant needs to scan the code by using hardware equipment such as a code scanning gun or a POS integrated machine to collect the money. However, the mobile phone can also have a code scanning collection function by registering some third-party payment software with lower requirements, so that the mobile phone can pretend to be the identity to participate in the collection process. Specifically, the third-party payment software is registered as a money receiving merchant by the merchant identity, and then the payment code is scanned by using a mobile phone and the amount value is input, so that the payment can be received. When the customer shows the payment code, someone may steal and scan the payment code by using a mobile phone at one side to steal the payment code, thereby causing money loss to the customer.
In summary, certain security risks exist in the information interaction process.

When information interaction is carried out, the driving unit selectively drives at least part of the infrared light emitting layers in the light emitting areas of the labels to emit infrared light, so that the infrared light has a specific pattern, and the information interaction terminal receives the infrared light and acquires the specific pattern to realize information interaction. Because the infrared light generated by the information interaction label structure is invisible light, information is difficult to know in the transmission process, and the risk of information embezzlement can be effectively reduced; meanwhile, the information interaction tag structure generates infrared light, so that the information interaction terminal needs to be provided with a special structure to receive information, and the difficulty of information acquisition is increased. Namely, the information interaction tag structure can effectively improve the safety in the information interaction process.
2. The information interaction device provided by the invention comprises an information interaction label structure. When information interaction is carried out, the information interaction label structure emits infrared light with a specific pattern, and the information interaction terminal receives the infrared light and obtains the specific pattern to realize information interaction. Because the infrared light generated by the information interaction label structure is invisible light, information is difficult to know in the transmission process, and the risk of information embezzlement can be effectively reduced; meanwhile, the information interaction tag structure generates infrared light, so that the information interaction terminal needs to be provided with a special structure to receive information, and the difficulty of information acquisition is increased.

When information interaction is carried out, the information interaction label structure generates infrared light with a specific pattern, and the information interaction terminal receives the infrared light and acquires the specific pattern to realize information interaction. Because the infrared light generated by the information interaction label structure is invisible light, information is difficult to know in the transmission process, and the risk of information embezzlement can be effectively reduced; meanwhile, the information interaction tag structure generates infrared light, so that the information interaction terminal needs to be provided with a special structure to receive information, and the difficulty of information acquisition is increased. Namely, the information interaction tag structure can effectively improve the safety in the information interaction process.
