Problems solved by technology

The disadvantage is that the initial digital password is too simple (such as 0000 or 1234), even if the user modifies the password with several digits, it will bring a greater memory burden to the user, and the consequences of forgetting it will be relatively large

[0004] 2. Application number / patent number: 200810303556, by setting an image method, it needs to go to subjective memory, which increases the user's memory burden

[0005] Although fingerprint encryption and voice encryption are relatively safe, they also have certain shortcomings. Due to changes in physiological characteristics or physiological activity performance affected by the objective environment, there is a risk of being overwhelmed within a certain period of time.
