Abstract

Embodiments herein are directed security access. Embodiments include an electronic lock that executes a time-based cryptographic algorithm to compute a time-based access code. The electronic lock compares the time-based access code with a received access code, and grants access to one or more lock features when the time-based access code matches the received access code. Embodiments also include providing an unlock code, including receiving a lock identifier and a user identifier. The lock identifier and the user identifier are sent to a remote computer system, and an access code for the lock is received from the remote computer system. Embodiments also include an electronic lock that receives and verifies an access code that includes a validity start time and a validity end time. When the current time is within the validity start time and the validity end time, the electronic lock grants access to one or more lock features.

Claims

1. At a mobile computer system including one or more processors and system memory, a method for providing an unlock code for a lock, the method comprising:

receiving a lock identifier for a lock;

receiving a user identifier identifying a user of the mobile computer system;

sending the lock identifier and the user identifier to a remote computer system;

based on sending the lock identifier and the user identifier to the remote computer system, receiving an access code for the lock.

2. The method as recited in claim 1, wherein receiving the lock identifier for the lock comprises scanning a machine-readable optical identifier on the lock, or receiving the lock identifier over a radio communications medium.

3. The method as recited in claim 1, wherein receiving an access code for the lock comprises receiving an access code that was generated by a time-based cryptographic algorithm.

4. The method as recited in claim 1, further comprising receiving one or more log entries from the lock, and sending the one or more log entries to the remote computer system.

5. The method as recited in claim 1, further comprising receiving one or more of log entry count or a log hash from the lock, and sending the log entry count and/or the log hash to the remote computer system.

6. The method as recited in claim 1, further comprising receiving a battery level from the lock, and sending the battery level to the remote computer system.

7. The method as recited in claim 1, further comprising receiving a time stamp from the lock, the time stamp indicating a time of a real-time clock at the lock, and sending the time stamp to the remote computer system.

8. The method as recited in claim 1, further comprising receiving Bluetooth pairing information over a NFC communications medium, a RFID communications medium, or a machine readable optical identifier, and automatically initiating a Bluetooth paring operation based on the received Bluetooth pairing information.

9. The method as recited in claim 1, further comprising sending the access code to the lock using one or more of visible light or sound.

10. An electronic lock, comprising:

one or more processors that are configured to;

execute a time-based cryptographic algorithm to compute a time-based access code;

compare the time-based access code with a received access code; and

grant access to one or more lock features when the time-based access code matches the received access code;

a machine-readable optical identifier that encodes at least a lock identifier of the electronic lock; and

an input device configured to receive an access code and communicate the access code to the one or more processors.

11. The electronic lock as recited in claim 10, wherein the machine-readable optical identifier comprises a dynamic display.

12. The electronic lock as recited in claim 11, wherein the machine-readable optical identifier is also configured to encode a time received from a clock at the electronic lock.

13. The electronic lock as recited in claim 11, wherein the machine-readable optical identifier is also configured to encode a battery level of a battery at the electronic lock.

14. The electronic lock as recited in claim 11, wherein the machine-readable optical identifier is also configured to encode a log entry of a log at the electronic lock.

15. The electronic lock as recited in claim 11, wherein the machine-readable optical identifier is also configured to encode a log entry count of a log at the electronic lock.

16. The electronic lock as recited in claim 11, wherein the machine-readable optical identifier is also configured to encode a hash of a log at the electronic lock.

17. An electronic lock, comprising:

one or more processors that are configured to;

receive an access code that includes a validity start time and a validity end time;

verify authenticity of the received access code;

determine if a current time is within the validity start time and the validity end time; and

when the current time is within the validity start time and the validity end time, grant access to one or more lock features; and

an input device configured to receive the access code and communicate the access code to the one or more processors.

18. The electronic lock as recited in claim 17, wherein verifying authenticity of the received access code comprises decrypting or decoding the access code with a shared key.

19. The electronic lock as recited in claim 17, further comprising a machine-readable optical identifier.

20. The electronic lock as recited in claim 19, wherein the machine-readable optical identifier encodes one or more of a lock identifier, pairing information, lock status information, or log information.
