Physical access control systems with localization-based intent detection
Systems and techniques for a physical access control systems with localization-based intent detection are described herein. In an example, an access control system may regulate access to an asset. The access control system is adapted to receive a credential of a user from a key device associated with the user using a first wireless connection. The access control system may be further adapted to establish a second wireless connection with the key device. The access control system may be further adapted to determine the user intends to access the asset based on a data set generated derived from the second wireless connection. The access control system may be further adapted to use a trained machine learning model to determine the intent of the user to access the asset. The access control system may be further adapted to transmit a command to grant access to the asset.
1. A method for regulating access to an asset in an access control system, the method comprising:
receiving a credential of a user from a key device associated with the via a first wireless connection using a low power communication protocol;
establishing a second wireless connection with the key device using Ultra-Wideband (UWB);
determining the user intends to access the asset based on a data set generated based on the second wireless connection, wherein determining the user intends to access the asset comprises:
determining a probability the user intends to access the asset using the generated data set and a trained machine learning model, wherein the trained machine learning model is trained with data sets collected from a plurality of users; and
determining the probability exceeds a predetermined threshold;
providing the credential to an access controller of the access control system for validation in response to determining the user intends to access the asset; and
receiving a validation indication from the access controller and transmitting a command to grant access to the asset.
2. The method of claim 1 , wherein the first wireless connection is Bluetooth Low Energy.
3. The method of claim 1 , wherein the data sets include movement data for the plurality of users within a range of the asset.
4. The method of claim 3 , wherein the data sets include a time of day timestamp and wherein the generated data set is timestamped.
5. The method of claim 1 , wherein the data sets include movement data from the plurality of users and wherein the key device provides movement data from an accelerometer of the key device.
6. The method of claim 1 , wherein determining the user intends to access the asset further includes using data received from a calendar system.
7. The method of claim 6 , further comprising:
identifying an event in the calendar system associated with the asset; and
identifying an indication of attendance to the event by the user.
8. The method of claim 1 , wherein the asset is a physical location.
9. The method of claim 1 , wherein the asset is an electronic device.
10. A system for regulating access to an asset in an access control system, the system comprising:
at least one processor; and
memory including instructions that, when executed by the at least one processor, cause the at least one processor to:
receive a credential of a user from a key device associated with the user via a first wireless connection using a low power communication protocol;
establish a second wireless connection with the key device using Ultra-Wideband (UWB);
determine the user intends to access the asset based on a data set generated based on the second wireless connection, wherein determining the user intends to access the asset further comprises instructions to:
determine a probability the user intends to access the asset using the generated data set and a trained machine learning model, wherein the trained machine learning model is trained with data sets collected from a plurality of users; and
determine the probability exceeds a predetermined threshold;
provide the credential to an access controller of the access control system for validation in response to determining the user intends to access the asset; and
receive a validation indication from the access controller and transmit a command to grant access to the asset.
11. The system of claim 10 , wherein the first wireless connection is Bluetooth Low Energy.
12. The system of claim 10 , wherein the data sets include movement data for the plurality of users within a range of the asset.
13. The system of claim 12 , wherein the data sets include a time of day timestamp and wherein the generated data set is timestamped.
14. The system of claim 12 , wherein the key device provides movement data from an accelerometer of the key device.
15. The system of claim 10 , wherein determining the user intends to access the asset includes using data received from a calendar system.
16. The system of claim 15 , further comprising instructions to:
identify an event in the calendar system associated with the asset; and
identify an indication of attendance to the event by the user.
17. The system of claim 11 , wherein the asset is a physical location.
18. The system of claim 11 , wherein the asset is an electronic device.
19. The method of claim 1 , further comprising storing the credential in cache memory, wherein providing the credential to the access controller comprises transferring the credential from the cache memory.
20. The method of claim 19 , further comprising removing the credential from the cache memory based on at least one of:
receiving an indication the user is not permitted to access the asset;
losing the second connection with the key-device; or
an elapsing of a predetermined time.
