Gesture-based password entry to unlock an encrypted device

摘要

Systems and techniques are provided for gesture-based password entry to unlock an encrypted device. A gesture input from a user to a gesture interface may be received. The gesture input may be converted to gesture data which may be hashed using a hashing algorithm to obtain a table key. A table including a master key may be encrypted using the table key. The master key may include a key for decrypting a primary storage that is at least partially encrypted. A second gesture input may be receive. The second gesture input may be an input from a user to the gesture interface. The second gesture input may be converted to second gesture data which may be hashed using the hashing algorithm to obtain a key equivalent to the table key. The table including the master key may be decrypted using the key equivalent to the table key.

1. A computer-implemented method performed by a data processing apparatus, the method comprising:
receiving a gesture input, wherein the gesture input is an input from a user to a gesture interface; converting the gesture input to gesture data; hashing the gesture data using a hashing algorithm to obtain a table key; and encrypting a table comprising a master key using the table key, wherein the master key comprises a key for decrypting a primary storage that is at least partially encrypted.
