Virtual Teller Check Unique Pattern Security

The patent applies the copying principle by creating a virtual teller check that is a digital replica of a physical check. The system generates a virtual check image that can be transmitted and stored electronically, replacing the need for physical check handling while maintaining the fundamental check functionality. This digital copy approach enables enhanced security features without the complexity of physical security infrastructure.

The patent incorporates color changes as a security feature by including a color-shifting element in the virtual check design. This element changes color when viewed from different angles or under different lighting conditions, making it difficult for counterfeiters to replicate accurately. The color-shifting feature is integrated into the virtual check image, allowing authentication without physical manipulation.

The patent applies asymmetry by incorporating a unique, irregular pattern into the virtual check that is difficult to replicate. The pattern includes asymmetric geometric shapes and non-repeating designs that vary for each check, making them ideal for authentication. The asymmetric pattern is embedded in the virtual check image and serves as a key authentication feature that validates the check's authenticity.

The patent implements preliminary action by pre-generating and storing the unique pattern and color-shifting elements in the virtual check before the check is issued. The authentication data and pattern characteristics are prepared in advance and embedded in the virtual check image, so that validation can be performed quickly without complex real-time calculations. This preliminary preparation reduces the complexity of the validation process while maintaining high security standards.
