Embodiment Construction

[0041] Integrating a security processing circuit or a security circuit on the same integrated circuit as at least one sensor module achieves benefits in terms of integration and security, because sensor information does not need to be conducted in leads outside the integrated circuit. Sensor information can include fingerprint data or other biometric data, which is personal in nature. Furthermore, where biometric data is used as part of an access control solution, the theft of reference data can also compromise the access control solution. In addition, tampering with reference data may cause attackers' interest due to various reasons such as stealing the device.

[0042] For example, in IoT devices, a high-security microphone may be required as a biometric sensor module, for example, for voice passwords. Integrating the sensor module and the security circuit into the same integrated circuit needs to solve the problem of generating access windows to the outside of the silicon chi...

Abstract

According to an example aspect of the present invention, there is provided an apparatus comprising a silicon layer comprising security circuitry and a first part of a first sensor, an insulator layer attached on the silicon layer, comprising integrated therein a second part of the first sensor, and a conducting pathway coupling the security circuitry to the first sensor, comprising a portion extending on the insulator layer and portions extending at least partly through the insulator layer.

Description

Technical field [0001] The present invention relates to the field of semiconductors and integrated sensors such as biometric sensors. Background technique [0002] The security of personal information in electronic communication is very important. Internet banking, cloud services, and e-commerce, for example, rely on reliable and secure methods to process sensitive information and payments. Encryption, hash functions, and standardized protocols are used to achieve these goals in a way that users can trust and trust. [0003] Personal devices can be equipped with mechanisms to prevent theft or unauthorized use. For example, a smart phone may include a fingerprint reader that is convenient for the owner and discourages use by thieves. Fingerprint readers can also be used in storage units for storing medicines, for example. Facial or voice recognition systems can be used to unlock devices, doors or other electronic security devices. [0004] Facial recognition systems can work by f...
