The encrypted storage file includes log files, photos, audio, and video One or more of

S3: The encrypted folder is hidden after it is created.

As shown in FIG. 3, a fingerprint-based encrypted file reading system includes a setting module 1, a creation module 2, an acquisition module 3, an identification module 4, a storage module 5, an encryption module 6, and a display module 7. The setting module 1 Set the encrypted fingerprint input by the user. Multiple encrypted fingerprints can be set. The encrypted fingerprint and the unlocking fingerprint of the mobile terminal use different finger fingerprints; the creation module 2 creates a corresponding encrypted folder based on the fingerprint entered by the user; the acquisition module 3 obtains the user Fingerprint entered on the mobile terminal; identification module 4 identifies whether the fingerprint entered by the user is consistent with the unlock condition of the encrypted folder; storage module 5 stores the file in the corresponding encrypted folder; encryption module 6 hides the encrypted folder; display Module 7 opens the corresponding encrypted folder according to the fingerprint display input by the user on the mobile terminal, and reads the file.

As shown in FIG. 4, a fingerprint-based encrypted file reading method, which reads a stored file, includes the following steps:

S1: The mobile terminal obtains the fingerprint input by the user,

S2: The fingerprint is matched with the encrypted fingerprint of the encrypted folder. When the matching is opened, the corresponding encrypted folder is opened. When the input fingerprint matches the encrypted fingerprint 1, the mobile terminal switches to display the encrypted folder corresponding to the encrypted fingerprint 1, and nothing else. The encrypted folder of the encrypted fingerprint remains hidden. When the input fingerprint matches the encrypted fingerprint 2, the mobile terminal switches to display the encrypted folder corresponding to the encrypted fingerprint 2, and so on to read the file.
