which uses our ¡§Mobile Encryption Proximity Sensor¡¨ to unlock mobile devices and apps. It incorporates NFC (Near Field Communication) technology and the conceptions of encryption and invisibility with the files to embody the key to decipher the password. It also increases the difficulties for mobile devices to crack the code and improves the safety of utilizing mobile devices. ¡§Mobile Encryption Lock¡¨ functions with its own application program and is able to encrypt and dematerialize all sorts of files existing within the mobile devices. With the capability to lock down all apps, Mobile Encryption Lock guarantees the protection of personal information security. The encrypted and dematerialized files and locked apps could only be accessed to the user with the Mobile Encryption Proximity Sensor itself.
