D4.3 Biometric photosensor for users’ identification - EXECUTIVE SUMMARY

Task 4.3 – Validation of biometric photosensor for users’ identification

This deliverable describes the validation of the biometric photosensor related to Task 4.3 -Validation of biometric photosensor for users’ identification.

In the first section the mechanical integration of the biometric photosensor and electronics into the Cooltra scooter (Askoll) is investigated. The best location for integration of both elements was determined and located in the front of the scooter. However, due to the minimalistic design of the scooter, the current solution would require adaptations to the body work. A solution would come from minimizing the readout/driving electronics such that it can be fully integrated. The cut out required for the sensor can be done post fabrication of the body work and does not hamper integration. Electrically, the electronics should be powered by the 12V delivered by the scooter battery, which is feasible with the current photosensor.

In the second section the main life time and reliability tests are described. The life time in ambient, tested by exposure to accelerated climate conditions, and the mechanical reliability to scratch resistance were selected as the most relevant test parameters, since the integration of the sensor is with a hard plastic cap (to prevent ambient light causing too much variation in the fingerprint readout and liveness detection) preventing direct UV exposure and direct impacts to the sensor. It was found that the samples survive exposure to 50 °C and 90 % relative humidity for 300 h and scratch tests with 1N load and varying testing conditions. This clearly demonstrates that the thin film encapsulation in combination with the developed hard coat is sufficient protection for the photosensor to be applied as biometric sensors in scooters.

The final section is about further security assessment, as an extension to those reported in D3.3. In D3.3 the results of the initial security assessment showed that still 25% of the security assessments were not fulfilled. Now both the implementation of security assessment as well as the vulnerability testing of these requirements has been assessed. The results of the second security assessment show that 100% of the security requirements are covered. Out of 44 security assessments, 30 passed and 14 passed with comments.
