A Random and Unselectable Graphic Password Scheme

The most widely popular graphic password design scheme among them is the Android graphic unlocking scheme (AUP). AUP and AUP based graphic password schemes often use only a very small part of their theoretical password space in practical use, resulting in AUP’s actual security far falling short of theoretical security. Therefore, AUP actually has significant security risks and is more susceptible to attacks and cracking by attackers. This article proposes a random and non optional graphic password scheme, which effectively avoids the potential risk of shoulder scanning attacks due to its randomness. In addition, the scheme incorporates image elements, making the user’s memory of the set password more vivid and vivid. In this scheme, the image is divided into 8x8 squares, and the password setting habit is broken to avoid the problem of overly simple passwords caused by user usage habits. Additionally, a randomly selected square is designed to effectively prevent enumeration attacks, brute force attacks, and shoulder scanning attacks, resulting in higher security and ease of use.
