Embodiment Construction

[0046] figure 1 A portable electronic device in the form of a mobile telephone 1 is shown. The mobile phone has a housing 10 , input / output means in the form of a touchscreen display 17 and further input means in the form of buttons 12 . An output device in the form of a loudspeaker is arranged below the first opening 13 at the front of the housing 10 . Further openings 14 , 15 and 16 are provided in the lower side wall region of the housing 10 . Behind these openings, components such as microphones, additional speakers and connectors are located. Furthermore, behind any of these openings there may be arranged sensors such as humidity sensors, temperature sensors and sensors for detecting at least one chemical analyte (ie one or more chemical sensors). A chemical sensor may comprise one or more sensor units, each sensor unit exhibiting a different sensitivity to a selected analyte. The mobile phone runs an operating system routine or application program (app) for operating...

Abstract

A chemical sensor (11) of a portable electronic device (1) is authenticated by reading a cryptographic sensor identifier from a memory of the chemical sensor and transmitting sensor-related data from the portable electronic device to a remote evaluation unit (6), the sensor-related data comprising the cryptographic sensor identifier. The sensor-related data may be transmitted in encrypted form. The sensor-related data may be complemented with a device identifier for the portable electronic device.

Description

technical field [0001] The present invention relates to a method of authenticating a chemical sensor of a portable electronic device, a correspondingly configured portable electronic device, a corresponding server-based authentication system, and corresponding software. Background technique [0002] Portable electronic devices such as mobile phones, tablets, laptops, etc. have become ubiquitous in our daily lives. Such devices today are equipped with multiple sensors, including gyroscopes, acceleration sensors, magnetic field sensors, proximity sensors, cameras, GPS modules, and more. It is expected that more sensors, especially those sensitive to chemical analytes, can be integrated into portable electronic devices. Such sensors will be referred to as "chemical sensors" hereinafter. [0003] In particular semiconductor sensors are known for this purpose. Such sensors have a sensitive layer having at least one electrical property that changes in the presence of one or mor...
