  • Publication number: 20210256104
    Abstract: An information processing apparatus includes a voice input processing unit, a memory, and a controller. The voice input processing unit takes in voice of a user of the information processing apparatus to convert the voice into a first voice signal. The controller extracts a first voice feature from the first voice signal to compare it with voice features registered in the memory. When the first voice feature is not matched with any voice features, the controller executes a process for storing the first voice feature in the memory to be associated with the registration target user, a process for generating a voice password based on the first voice feature, and a process for storing the voice password in the memory. The controller executes user authentication processing for an authentication target user by using the voice password in the memory by the user registering process.

  • Publication number: 20210258786
    Abstract: A wireless LAN communication system which achieves convenience where a terminal of a user who is external to an organization can temporarily use the system while ensuring security. For example, a first terminal is used by a user internal to an organization and a second terminal is used by a user external to the organization. A communication device has a display function and the first terminal connects to the communication device via a wireless LAN access point device. The second terminal connects, under permission from the first terminal, to the communication device via the wireless LAN access point. The second terminal uses the display function of the communication device through the connection via the wireless LAN access point. The first terminal and the communication device confirm whether the permission is to be continued or terminated to make the second terminal unable to use the display function.
