The Cancel button plays a role in terminating the setup when a user does not want to setup the SLSTP for a locking screen.
TPCO Manager (time pattern count operation manager) is responsible for counting the number of incorrect time patterns that are inputted by a user when the SLSTP is activated.
Activity consists of the Guide Viewer, which shows a novice SLSTP user how to use the system, the Setting Viewer, which sets a count for the number of allowable input times in a row and a time pattern for the SLSTP, and the Lock Viewer, which shows the SLSTP activation for users.
The initial screen of the SLSTP proposed in this paper is shown in Figure 4.
Figure 5 shows setup process locking mechanism of SLSTP. The left screen in Figure 5 shows an input screen for a time pattern to be set by the user.
Figure 6 shows waiting visualization for nonauthorizing access of SLSTP. The left screen in Figure 6 shows the activated status of the locking screen of SLSTP, while the right screen shows an activated status when a user enters an incorrect time pattern five times consecutively.
In this section, the SLSTP proposed in this paper is compared with the other popular locking systems, such as pattern lock, password, and PIN.
Table 2 shows the comparison of the SLSTP with other popular locking systems in terms of the pattern lock, password, and PIN limitations.
Since it is difficult for the SLSTP to estimate the time pattern of a single pressing, as shown in Table 2, pattern lock, password, and PIN were measured for this experiment.
On the other hand, since the number of locking patterns using the SLSTP is unlimited, the SLSTP can provide robust security strength to users.
