Goals:
-
For a given visitor, your system should be able to depict their face and email you to allow or deny them access.
-
If allowed access, you should be able to capture their information through a hosted web page. You should then send them an SMS message with a valid OTP that is only valid for a maximum of 5 minutes.
-
The OTP should be valid only once and guaranteed unique across the
different visitors. -
For a returning visitor, your system should
automatically send them an SMS message with a valid OTP. -
Given a valid OTP, a visitor should be able to input it and receive a personalized greeting.
-
Visitor Vault
- Create a S3 bucket ( B1†) to store the photos of the visitors.
- Create a DynamoDB table “passcodes” ( DB1†) that stores temporary access codes to your virtual door and a reference to the visitor it was assigned to a. Use the TTL feature1 of DynamoDB to expire the records after 5 minutes.
- Create a DynamoDB table “visitors” ( DB2†) that stores details about the visitors that your Smart Door system is interacting with.
-
Analyze
-
Create a Kinesis Video Stream3 ( KVS1†), that will be used to capture and stream video for analysis. You can use the built-in video recording feature in the Kinesis console to simulate a real streaming video camera.
-
Subscribe Rekognition Video4 to the Kinesis Video Stream (KVS1).
-
Output the Rekognition Video analysis to a Kinesis Data Stream (KDS1) and trigger a Lambda function for every event that Rekognition Video outputs.
-
-
Authorize
-
Create a second web page, the “virtual door”, that prompts the user to input the OTP. a. If the OTP is valid, greet the user by name and present a success message. b. If the OTP is invalid, present a “permission denied” message.
-
Note that you will have to build your own API to capture and validate the OTP.
