Summary:
With the acceleration of informatization, all kinds of information are flooded in our daily life, and the security of such information is also particularly important. In the relevant secret-related industries, the information leaked to the state due to personal reasons every year has caused huge losses to the society, and the attacks of library towing and credential stuffing have emerged in an endless stream, and personal computers have also become broilers because of the leakage of account passwords. In the course of on-the-spot investigation, it was found that most of the sensitive personnel of secret-related units were still using notepads to record some sensitive information, such as account numbers and passwords, which caused great inconvenience to work and life.
In view of this situation, in order to facilitate the use of non-consumer people, this project uses the existing mature AES encryption technology, SQLite database, canvas technology, AsyncTask technology, intent technology, and front-end programming technology to design and implement the software.
This subject can mainly easily record a variety of text or information entered by the user, at the same time, the information is encrypted and stored locally, and decrypted when needed, the software brings a certain convenience to the work of relevant personnel, improves work efficiency, and reduces the risk of information leakage.
