Abstract
Methods and devices for NFC-tap file encryption, decryption and access via Near Field Communication (NFC) are disclosed. A user can select an unencrypted file stored in a computing device for encryption. Upon encryption, the file name of the selected file and the encryption key used to encrypt the selected file are transmitted to an NFC-enabled wireless device for storage. The user can select an encrypted file stored in the computing device for access. As the user taps the computing device with the wireless device, the file name of the selected file is transmitted to the wireless device, which in turn transmits a decryption key for decrypting the selected file to the computing device. The computing device decrypts the selected file with the decryption key. The user can now access the decrypted file.
