Researchers at Universidad Politecnica de Madrid's Group of Biometrics, Biosignals, and Security say they have developed a biometric authentication technique that provides higher security than the use of a personal identification number.
The researchers say the system can be applied to the e-commerce industry, protecting transactions that require user identity verification or preserving private information that is stored in the mobile device. They hope to increase the security in these services and transactions by using biometrics and cryptographic techniques.
One technique is based on an in-air signature made with a mobile device that is equipped with an accelerometer. The sensor can analyze the accelerations of the signature, using the information to verify the identity of the user and allow secure transactions to be completed. The researchers have developed algorithms that maximize the accuracy of the system, achieving an error rate of three percent. They say their test results demonstrate the viability of an in-air signature as a biometric security technique.
