BACKGROUND

The invention is a digital interface on the electronic device for identifying human or electronic activation of the device. The user is challenged with an image captcha consisting of various panels and is asked to identify the challenge points. The image-based captcha challenge is repeated at least twice in tandem to ensure user identity as a human. The electronic device is configured to detect at least one input from the user in both challenges and it allows access to the use of the electronic device only when both inputs match.

APPLICATIONS

• Secure access to the electronic device

• Security check for use of various laboratory instruments

• If the security device is linked with an alarm system, it can be used in sectors containing sensitive equipment/machines to warn of unauthorized access.

ADVANTAGES

• Secures authorized use of the electronic device
