Methods and systems for providing bidirectional authentication
Abstract:
Methods and systems for providing access to a secure computing device are disclosed. A security device is used to generate a one-time password, a sequence of symbologies, and location information. The security device transmits the password, sequence and location information to the secure computing device for storage and displays the password and sequence to a user. A user device provides a password to the secure computing device in order to obtain access. The secure computing device compares the password with the stored one-time password to verify the user of the user device and sends the sequence to the user device in response. The user or user device verifies the sequence of symbologies to confirm the secure access. The location information may be used to detect fraudulent accesses to the user account.
