MobiComBiom

Mobile Comunication Biometrics

MobiComBiom is an amplification of the product «ComBiom», which is a software providing a unique multimodal simultaneous biometric authentication process. Thereby the biometric face recognition, the biometric voice recognition, the recognition of the biometric lip movement and word recognition are carried out simultaneously, requesting the user to speak four randomly generated numbers (Random Challenge Response or otp = one time password).This authentication process guarantees highest security, highest user-comfort and low hardware costs (only a webcam is required).

Development of Mobil Technology: Mobile All-rounder as our steady companion

Mobile technology has advanced quickly and created all-rounder which accompany and support us in our day-to-day life. They yield many possibilities of applications, but are also associated with high risks. Who can guarantee that the user of a handheld is actually allowed to use all the mobile services?

MobiComBiom, the Swiss Solution of BIOMETRY.com AG

To solve this security problem, BIOMETRY.com AG developed the product MobiComBiom (Mobile Communication Biometrics). It enables distinct authentication of the user containing the biometric face recognition, the biometric voice recognition, the recognition of the biometric lip movement and word recognition, - requested simultaneously through four randomly generated numbers  (Random Challenge Response or otp = one time password).

Pushing a specific «Soft Button» on the mobile phone (e.g. number 1 and 3 are simultaneously pushed), the authentication process of MobiComBiom starts. Thereby four randomly generated numbers appear on the display. Similar to video phoning, the user speaks the numbers. The video and audio data are saved and transferred to the provider (the so called Trust Center). There, every number is converted into a file (templates, approx. 4KB). These files are then compared with the reference data, which the user previously taught-in for all the numbers from 0,1,2… to 9. If the data matches, the user of the mobile phone is clearly authenticated. 

MobiComBiom, Higher Security for Mobile Payment

For Mobile Payment, the process is the same way executed as described above. If the authentication is positive, the user receives a 2D bar code as a confirmation, sent to his mobile phone, which he can use for payments at the point of sale (e.g. shops).

Right after the authentication (approx. 10min), the bar code contents 100% trust level. Therefore, the maximum amount of money, which was authorised by the bank, may be spent (e.g. 5000 euro). To counteract the steadily increasing risk of a theft, the percentage rate subsequently decreases to lower percentages and amounts (e.g. 500 euro). Thereby, a trust level of at least 10% (e.g. 50 euro) is always guaranteed to assure lower payments, for example for parking fees. With every phone call, the biometric voice is recognized and in case of a match, the trust level increases.

The increase of the trust level is limited to 10% per phone call and a fixed level of 50% cannot be exceeded. This is because clever hackers could execute a replay attack on only one single biometric mode. Whereas there is no such danger for the multimodal biometric authentication with random challenge response, provided by MobiComBiom. Furthermore, if the user is exposed to loud background noise and wants to increase his trust level, there is also the possibility to use the biometric face recognition instead. If the user wants to use the maximum amount of money, he just has to authenticate himself. This means, he simply starts MobiComBiom and speaks to four generated numbers.

MobiComBiom is a very secure process and at the same time offers customer friendliness due to FreeHaM (Free Hands and Memory). Moreover there is no high hardware investment; Webcam and Microphone come standard with newer mobile phones.
