Preferences provide capabilities for processing data in the form of key-value (KV) pairs and supports lightweight data persistence, modification, and query. In KV pairs, keys are of the string type, and values can be of the number, string, or Boolean type.

### Function
Personal Identification Number (PIN) authentication provides user authentication capabilities and applies to identity authentication scenarios, such as device unlocking, payment, and app logins. After a user registers a PIN, the PIN authentication (pin_auth) module unlocks the device only when a correct PIN is entered. The figure below shows the architecture of PIN authentication.
Personal Identification Number (PIN) authentication provides user authentication capabilities in identity authentication scenarios, such as device unlocking, payment, and app logins. After a user registers a PIN, the PIN authentication (pin_auth) module unlocks the device only when a correct PIN is entered. The figure below shows the architecture of PIN authentication.
The pin_auth driver is developed based on the Hardware Driver Foundation (HDF). The pin_auth driver model shields hardware differences and provides stable PIN authentication capabilities for the user IAM framework(UserIAM) and PIN authentication system ability (SA). The PIN authentication capabilities include obtaining the PIN authentication executor list, executor information, anti-brute force information of the specified template, comparing the template list of the executor and that of UserIAM, enrolling or deleting PINs, and performing PIN authentication.

### Basic Concepts
The identity authentication consists of UserIAM and basic authentication services (including PIN authentication and facial recognition). It supports basic functions such as setting and deleting user credentials, deletion, and performing authentication.
