The SignHear signature verification system is the patented ground breaking technology developed by Sign Assured Ltd. The SignHear system like no other uses the sound of your handwritten signature to verify your identity. The traditional methods of comparing the images of signatures are both insecure and costly, though the acceptance by customers has kept it alive well past its sell-by date. What SignHear bring to the market place is a system, which is low in cost, high in robustness and high in user acceptability.
The images of signatures have been easily forged by fraudsters for many years past, giving rise to a varied range of hard-to-use security systems such as PIN numbers, passwords and a host of ID tokens. Signatures however are not as insecure as the market will have you to believe, replicating the image is easy, replicating how-it-is-done is much more difficult. It is this unseen behaviour of signing which SignHear captures and uses to verify its customers. The combination of movements across a surface creates a set of sounds, which is uniquely identifiable to the customer, enabling replication from an image almost impossible. This combination of movements gives rise to a behaviour which can only be done by the customer when they so choose, thus SignHear does not only indicate the presence of the customer, or the presence of their token/PIN/fingerprint/etc, but it also shows intent. It shows that the customer intended to carry out the task in question, and it was no mere mistake they had submitted their signature. This factor becomes highly important in mission critical environments. It is true that signatures do vary even when the same customer signs the same signature again, though the pattern of ‘how' the customer signs remains very much the same and the robust algorithms of SignHear caters for this.
The capturing of signatures sounds requires a tough surface, and in the case of SignHear, a steel pad is the input surface onto which the customer signs. Therefore, SignHear is highly robust, as the only exposed sensor of this Biometric device is a piece of coated metal, making SignHear suitable for a huge number of environments ranging from office based to factory the floor to the front lines of war.
The usage of sound to capture a signature reduces the complexity of the processing system considerably, thus enabling the price of this eloquent Biometric technology to be highly competitive. And with the universal acceptance by customers of signatures as a form of identity and intent verification, SignHear makes available to the market place a very attractive offering in the form of a highly robust, low cost and customer friendly biometric solution.
