Problems solved by technology

[0012] However, when sending instructions to the environmental sensor from various terminals including mobile terminals, the terminal must be prepared (that is, user authentication cannot be performed without the terminal), and when the input unit is installed on the environmental sensor itself, the presence of the environmental sensor Issues of size, complexity and cost increase

Embodiment 1

[0052] figure 1 A block diagram of the environmental sensor module 1 as the environmental sensor of this embodiment is shown in . The environmental sensor unit 1 includes: a plurality of types of sensors 4a to 4g as sensor elements, a flash memory 5 temporarily storing measurement results, a communication module 2 capable of communicating with external devices, and an MCU (Micro Controller Unit) as a processing device. )3. As a plurality of types of sensors 4a to 4g, more specifically, a temperature and humidity sensor 4a, an illuminance sensor 4b, a UV sensor 4c, an air pressure (absolute pressure) sensor 4d, an acceleration sensor 4e, a microphone (acoustic sensor) 4f, a CO 2 The sensor 4g can continuously acquire the surrounding environment data of the environment sensor unit 1 . In addition, by using the communication module 2 to communicate with a remote control device (not shown) such as a smartphone, the environmental data detected by the sensors 4a to 4g can be sent ...

Embodiment 2

[0083] Next, a second embodiment of the present invention will be described. In this embodiment, a case where user authentication is performed based on other physical quantities measured by the environmental sensor unit 1 , specifically, changes in the sound pressure level detected by the microphone 4 f will be described. In addition, in this embodiment, only the type of physical quantity used for user authentication and the "prescribed rules" are different from Embodiment 1, and the configuration of the environmental sensor unit 1, the flow of abnormal response processing, etc. are the same as Embodiment 1. Therefore, for This section uses the same symbols and omits detailed explanations.

[0084] Figure 6 It is a graph showing the value of the sound pressure level detected by the microphone 4f on the vertical axis, the elapsed time on the horizontal axis, and their relationship with the time of user authentication. Such as Figure 6 As shown, after the sound pressure lev...

Embodiment 3

[0088] Next, Embodiment 3 of the present invention will be described. In this embodiment, a description is given based on a plurality of physical quantities measured by the environmental sensor unit 1, specifically illuminance and CO 2 The change of the data of the value is an example of performing user authentication.

[0089] Figure 7 A flow chart of processing for user authentication in the MCU 3 of this embodiment is shown in . In addition, this program is a program stored in the memory in MCU3, and is repeatedly executed every predetermined time by the processor in MCU3.

[0090] When this program is executed, first, in S201, data of illuminance detected using the illuminance sensor 4b is extracted. When the process of step S201 ends, it progresses to step S202. In step S202, it is determined whether or not the state continues for a predetermined time after the extracted illuminance data has changed from a value higher than a predetermined illuminance threshold to a ...

Abstract

An authentication method and program for an environmental sensor and its user, without using other terminals and / or without adding other mechanical structures to the sensor, and effectively utilizing the sensor elements of the environmental sensor to perform user authentication. The environmental sensor is capable of measuring a physical quantity related to the surrounding environment, and includes: a single or a plurality of types of sensor elements capable of detecting the physical quantity; and when at least one of the sensor elements detects a physical quantity that fluctuates according to a prescribed rule (S101), a user authentication unit that determines that the change in the physical quantity is caused by the behavior of the user (S102).

Description

technical field [0001] The present invention relates to an environmental sensor capable of measuring multiple types of physical quantities related to the surrounding environment, and an authentication method and program for a user thereof. Background technique [0002] Currently, there has been proposed a device that includes various measurement units and measures biological information about a user or environmental information about a surrounding environment (for example, Patent Document 1). The device listed in Patent Document 1 includes a plurality of measuring units and notification units. In addition, various elements have been developed as sensor elements for detecting physical quantities such as temperature, humidity, air pressure, and light intensity. In particular, in recent years, small-sized and low-power-consumption sensor elements (hereinafter, all referred to as MEMS sensors) using MEMS (Micro Electro Mechanical Systems) technology have attracted attention. I...
