ADT Security System is defined into two operations. The first operation is pushing the button. Afterward, you insert the some data item in the form of structure, later you pop it. After you do both basic operations, you will get abstract data type. It is a theory that uses other thing to make a description of your abstract algorithm. This process will you to have implementation where later it becomes a module that will corresponded to ADT operation. Finally, your information of your data will hide by the system and nobody knows it except you. Therefore, your safety is really guaranteeing 100%. In conclusion, Abstract Data Type is very sophisticated technology system security. It is very appropriate for you who have valuable thing.
