Android解锁模式是一种广泛使用的图形密码形式，与所有密码方案一样，许多研究表明，用户选择了一组相对容易猜测且不多样化的密码。虽然已经提出了加强模式的建议，例如增加接触点的数量或改变接触点的位置，但自界面推出以来的十多年中，这些建议都没有得到实施。我们提出了一种新的方法;用户选择两个顺序的Android模式，即所谓的双重模式，而不是增加单个的复杂性，这两个模式在视觉上相互叠加。这允许在不显著改变接口的情况下增加复杂性。我们报告我们的初步调查结果的一个大型用户研究（n=634）的双重模式，发现强有力的证据表明，该计划是高度可用的，增加了用户选择的复杂性。
Android unlock patterns are a widely used form of graphical passwords, and like all password schemes, numerous studies have shown that users select a relatively guessable and non-diverse set of passwords. While proposals have been put forth for hardening patterns, such as increasing the number of or changing the location of contact points, none of these proposals has been implemented in the decade-plus since the interface's launch. We propose a new approach; instead of increasing the individual complexity, users select two sequential Android patterns, so called Double Patterns, that are visually super imposed on one another. This allows more complexity without dramatically changing the interface. We report on our preliminary findings of a large user study (n=634) of Double Patterns, finding strong evidence that the scheme is highly usable and increases the complexity of user choice.
