界: Input Validation and Representation
輸入驗證和表示法問題是由中繼字元、替代編碼和數值表示法引起的。信任輸入會導致安全問題。問題包括：「Buffer Overflows」、「Cross-Site Scripting」攻擊、「SQL Injection」及其他許多問題。
Predicate Injection
Abstract
透過使用不可信賴來源的輸入建構動態
NSPredicate 可讓攻擊者修改陳述式的意義。Explanation
NSPredicate 實例指定應如何從諸如 CoreData 持續性儲存系統、陣列和字典等來源中擷取或篩選集合。其查詢語言提供類似於 SQL 的易懂語言來定義搜尋集合所依據的邏輯條件。例如，能夠影響述詞的攻擊者可能會變更其意義，從而洩露資料、略過安全控制或模擬其他使用者。
範例 1：下列範例顯示在存取應用程式所儲存的部分資料時，
NSPredicate 如何用作驗證因素。由於使用者可以提供任意 PIN 值，他們將能夠使用萬用字元 (*) 來略過 PIN 保護。
NSString *pin = [self getPinFromUser];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"pin LIKE %@", pin];
